The Ads Glossary, A to Z

Every Facebook & Instagram advertising term, in plain language. 225 entries, updated July 2026

Agencies love jargon because it justifies invoices. Every term below is explained the way we'd explain it to a friend — because once the words make sense, running your own ads does too.

A

A/B test (split test): Running two versions of an ad (different image, text or audience) at the same time to see which performs better. Change one thing at a time, or you won't know what made the difference.
Ad: The thing people actually see: an image or video, text, headline and button. It lives inside an ad set, which lives inside a campaign.
Ad account: Your billing and campaign container on Meta. It holds the payment method, spending limits and history. Bridge24 connects to it through the official API; you stay the owner.
Ad auction: Every time someone could see an ad, Meta runs an instant auction. The winner is not the highest bid but the best mix of bid, estimated action rate and ad quality.
Ad fatigue: When the same people have seen your ad too many times and stop reacting. Rising frequency plus falling CTR means it is time for fresh creative.
Ad Library: Meta's public, searchable archive of every ad currently running. Free competitor research: search any brand and see exactly what they are testing.
Ad set: The middle layer of a Meta campaign. It decides who sees your ads (audience), where (placements) and when (schedule). Your ads live inside it.
Ads Manager: Meta's native tool for running ads. Powerful and famously overwhelming; the reason Bridge24 exists.
Advantage+ audience: Meta's AI-driven audience expansion. You give hints, it reaches beyond them whenever it predicts better results.
Advantage+ placements: Letting Meta automatically show your ad wherever it predicts the best results — feed, Stories, Reels, Messenger — instead of you hand-picking. Usually the right default.
Advantage+ shopping campaigns (ASC): A largely automated campaign type for e-commerce where Meta handles most targeting and placement decisions for you.
Always-on: Running ads continuously instead of in bursts. Keeps the learning data warm and your pipeline steady.
Angle: The persuasive idea behind an ad: saving time, saving money, status, fear of missing out. Same product, different angle, wildly different results.
AOV (Average Order Value): Revenue divided by number of orders. Raising AOV with bundles and upsells is often easier than lowering ad costs.
API (Application Programming Interface): The official pipe through which software talks to Meta. Bridge24 uses the Marketing API, the same one agency tools are built on.
App events: Actions inside a mobile app (install, signup, purchase) reported back to Meta so campaigns can optimize for them.
Aspect ratio: The width-to-height shape of your creative. 1:1 for feed, 9:16 for Stories and Reels, 4:5 for mobile feed.
Attribution: The question of which ad gets credit for a sale. Imperfect on every platform; directionally useful, never gospel.
Attribution window: How long after a click or view a conversion still counts for the ad. Meta's default is 7-day click, 1-day view.
Audience: The group of people your ad targets: defined by location, age, gender and interests — or built from your own data (see Custom audience).
Audience Network: Meta showing your ads inside third-party apps and sites. Cheap reach, mixed quality; check your placement breakdowns.
Audience overlap: When two ad sets target many of the same people and bid against each other in the auction, quietly raising your own costs.
Awareness (objective): The campaign objective that optimizes for people remembering your brand rather than clicking today.

B

B2B: Selling to businesses. Meta works better for B2B than its reputation suggests; decision-makers scroll like everyone else.
B2C: Selling to consumers. Meta's home turf.
Banner blindness: People's learned ability to ignore anything that looks like an ad. The cure is creative that looks like content.
Behavioral targeting: Reaching people based on what they do (purchase behavior, device, travel) rather than what they say they like.
Benchmark: A reference number to compare against, like a ~1% link CTR or the average CPM in your country. Useful as a compass, dangerous as a goal.
Bid: What you are willing to pay in the auction. With default settings Meta bids for you at the lowest workable cost.
Bid cap: A manual ceiling on your bids. An advanced tool; most accounts perform better without it.
Bid strategy: The rule Meta follows when bidding for you: lowest cost (the default), cost cap, bid cap or ROAS goal.
Billing event: What Meta charges you for — usually impressions (each time the ad is shown), even when you're optimizing for clicks or purchases.
BOFU (Bottom of funnel): People close to buying: cart abandoners, pricing-page visitors. Retargeting territory, and the cheapest conversions you will ever get.
Boosted post: The blue Boost button on a page post. Quick, but limited: fewer objectives and less control than a real campaign.
Brand awareness: How many people know you exist. Hard to measure day to day, very real over the long run.
Brand lift: The measured change in awareness or purchase intent caused by ads, usually via surveys. Big-budget territory.
Breakdown: Splitting results by age, gender, placement, country or time to see what is actually driving performance.
Broad targeting: Targeting with few or no interest filters, letting Meta's algorithm find your buyers. Counter-intuitively, it often beats hand-picked interests on modern campaigns.
Budget (daily / lifetime): A daily budget caps average spend per day; a lifetime budget caps total spend for the campaign's whole run. Daily is simpler and easier to reason about.
Business Manager / Meta Business Suite: Meta's hub where pages, ad accounts, pixels and people's permissions are owned and managed.
Buyer persona: A sketch of your typical customer used to guide targeting and copy. Useful until it replaces talking to real customers.

C

Call to action (CTA): The button on your ad: Shop Now, Sign Up, Book Now. Match it to the actual next step, not the most ambitious one.
Campaign: The top layer of Meta's structure. It holds your objective (what you want: sales, leads, traffic) and usually the budget. Inside it: ad sets, and inside those, ads.
Carousel ad: An ad with 2 to 10 swipeable cards, each with its own image and link. Great for product ranges and step-by-step stories.
Catalog: Your product list uploaded to Meta, powering dynamic product ads and shop features. See XML product feed.
Catalog sales: The objective that advertises products straight from your catalog to the people most likely to buy them.
CBO (Campaign Budget Optimization): Setting the budget at campaign level and letting Meta split it between ad sets automatically, favouring whichever performs best.
Click (all clicks): Any tap on the ad, including reactions and profile visits. The number to actually watch is link clicks.
Cold audience: People who have never heard of you. The most expensive to convert and the only way to grow.
Collection ad: A mobile format that opens into a full-screen product showcase (an instant experience) when tapped.
Conversion: The action you actually want: a purchase, a sign-up, a booked call. Counted by the pixel or the Conversions API.
Conversion rate (CVR): Conversions divided by clicks or visits. If purchases sit under ~1%, look at your landing page before blaming the ad.
Conversion value: The money amount attached to your conversions. It is what ROAS is calculated from, so track it honestly.
Conversions API (CAPI): A server-to-server channel that reports conversions from your website's backend to Meta — more reliable than the pixel alone now that browsers block trackers. Bridge24 gives you your CAPI token in one click.
Cookie: A small browser file used for tracking. A dying technology, which is exactly why the Conversions API exists.
Copywriting: The words in your ad. On Meta, the first line does 80% of the work.
Cost cap: A bid strategy telling Meta the average cost per result you can accept. Keeps costs predictable, can make spend bursty.
Cost per result: Meta's flexible metric: whatever your objective counts as a result, this is its unit price. Always check what the result actually is.
CPA (Cost Per Acquisition): Spend divided by conversions. Next to your margin, the number that decides whether ads are profitable.
CPC (Cost Per Click): What you pay on average for one click: spend ÷ clicks. Useful for comparing creatives, but ROAS matters more.
CPL (Cost Per Lead): Spend divided by leads. Judge it together with lead quality, never alone.
CPM (Cost Per Mille): The cost of 1,000 impressions. It's the "market price" of your audience's attention — high CPMs mean an expensive audience or weak creative.
Creative: The ad itself: the image or video, the primary text, the headline and the call-to-action button.
Creative testing: Systematically trying different hooks, formats and angles to find winners instead of betting everything on one guess.
Cross-sell: Advertising complementary products to people who already bought. Warm, cheap and usually neglected.
CTR (Click-Through Rate): Clicks ÷ impressions, as a percentage. Under ~0.9% your creative isn't stopping thumbs; above ~1.5% it's doing its job.
Custom audience: An audience built from people who already know you: website visitors, customer lists, video viewers. The raw material for retargeting.
Custom conversion: A conversion you define yourself from URL rules or events, like counting everyone who reaches /thank-you.
Customer lifetime value (LTV): Everything a customer spends with you over time. LTV higher than CPA is the whole game of paid acquisition.

D

Daily budget: The average amount Meta may spend per day on a campaign or ad set. Actual daily spend can flex ~25% up or down, but averages out.
Dark post: An ad that never appears on your page's timeline. Standard practice for testing many variants, nothing shady.
Dashboard: Where your numbers live. Bridge24's shows spend, results and delivery status synced with Meta, live.
Dayparting: Showing ads only at certain hours or days. On Meta it requires a lifetime budget.
Deep link: A link that opens a specific screen inside an app instead of a web page.
Delivery: Whether and how Meta is actually showing your ads. "Active" means running; "In review", "Learning" and "Rejected" are delivery states worth watching.
Demographics: Age, gender, location, language: the skeleton of any audience definition.
Destination URL: Where the click lands. Test it on a phone; that is where most of your clicks happen.
Detailed targeting: Meta's panel of interests, behaviors and demographics used to narrow an audience. See interest targeting.
Direct response: Advertising built to trigger an action now, not warm feelings later. Most small-business advertising is this.
DSA (Digital Services Act): EU regulation requiring ads shown in Europe to declare who pays for and benefits from them. Meta asks for a "beneficiary" on EU-targeted ad sets.
Duplicate: Copying a campaign or ad set to test a change without breaking what already works. One click in Bridge24.
Dynamic creative: You upload several images, texts and headlines; Meta mixes and matches them to find the winning combination.
Dynamic product ads (DPA): Automatically showing each person the exact products they browsed on your site, pulled from your catalog.

E

Earned media: Attention you did not pay for: shares, press coverage, word of mouth.
Engagement: Any interaction with your ad: reactions, comments, shares, clicks, video views. Nice to have; revenue is nicer.
Engagement custom audience: An audience of people who interacted with your page, posts, videos or forms. Free retargeting fuel.
Engagement rate: Engagements divided by reach or impressions. A quick health check for your creative.
Estimated audience size: Meta's rough count of how many people match your targeting. Too small (<100k) can starve delivery; there's rarely such a thing as "too big".
Event (pixel event): An action the pixel or Conversions API reports to Meta: ViewContent, AddToCart, Purchase. The vocabulary of tracking.
Event Match Quality (EMQ): Meta's score for how well your server events match real people. Higher scores mean better optimization.
Evergreen creative: An ad that keeps performing for months. Rare and precious; do not touch it while it works.
Exclusion: Removing groups from your targeting, like excluding existing customers from a prospecting campaign.

F

Facebook Page: Your business identity on Facebook. Ads are published from it, so keep the basics (photo, reviews, info) presentable.
Feed: The main scrolling stream on Facebook and Instagram — still where most ad money is spent and won.
First-party data: Data you own: customer lists, site visitors, app users. Gold, and getting more valuable every privacy update.
Format: The physical shape of the ad: single image, video, carousel, collection.
Frequency: How many times the average person has seen your ad (impressions ÷ reach). Above ~3–4, fatigue sets in: refresh the creative.
Frequency cap: A limit on how often one person sees your ad. Directly controllable only in reach campaigns; elsewhere, watch the frequency metric.
Full-funnel: Running ads for every stage at once: prospecting for strangers, proof for the curious, offers for the almost-ready.
Funnel: The path from stranger to customer: see it (TOFU), consider it (MOFU), buy it (BOFU).

G

GDPR: Europe's privacy law: consent for tracking and rights over personal data. Bridge24 is built around it; see the privacy policy.
Gender targeting: Limiting an audience by gender. Not allowed in special ad categories like housing or employment.
Geo targeting: Choosing where your ads show: countries, regions or specific cities. Tighter geography usually costs more per result — go city-level only for local offers.

H

Headline: The short bold line under your ad's image or video. Its whole job: make the click feel obvious.
Hold-out test: Deliberately excluding a group from your ads to measure the true incremental effect of advertising.
Hook: The first 1–3 seconds of a video ad. If it doesn't stop the scroll, nothing after it matters.
Horizontal video: 16:9 video. Fine for in-stream placements, weak in the mobile feed; shoot vertical when in doubt.
Hyperlocal targeting: A radius of a few kilometers around an address. Bread and butter for restaurants, salons, gyms and clinics.

I

Image ad: A single static visual. The fastest format to produce, and it still wins more often than people admit.
Impressions: The number of times your ad was displayed on a screen — whether or not anyone paid attention. The raw fuel for every other metric.
Instagram Explore: Instagram's discovery tab, available as a placement. Your ad reaches people actively browsing for new content.
Instant experience: A full-screen mobile page hosted by Meta that loads instantly from an ad. No website required.
Instant form (lead form): A pre-filled form that opens inside Facebook or Instagram. Leads without a landing page; watch quality.
Intent: How ready someone is to act. Search engines capture existing intent; Meta creates new intent.
Interest targeting: Targeting people by what Meta thinks they're into ("yoga", "e-commerce"). Increasingly beaten by broad targeting plus a strong creative.
iOS App Tracking Transparency (ATT): Apple's permission popup that cut ad tracking on iPhones and made the Conversions API a necessity.
Iteration: The habit that compounds: small changes tested weekly beat grand redesigns tested yearly.

J

Journey (customer journey): The path from stranger to customer: sees ad → clicks → visits site → buys. Every step you can measure is a step you can improve.
Junk leads: Form fills that never answer. Fight them with clearer copy, an extra qualifying question, or a real landing page.

K

Key visual: The one image or opening frame that carries your ad. If it does not stop the scroll, nothing else gets read.
Keyword targeting: What Meta does not have. Search engines target what people type; Meta targets who people are and what they do.
KPI (Key Performance Indicator): The one number that tells you if it's working. For most sales campaigns that's ROAS; for lead campaigns, cost per lead. Pick one and judge everything by it.

L

Landing page: The page after the click. Half of your ad performance is decided here, not in the ad.
Landing page view: Counted only when the page actually finishes loading. Stricter and more honest than a link click.
Lead: A person who gave you their contact details. The start of a sales conversation, not the end of one.
Lead magnet: The free thing (guide, discount, audit, sample) you trade for contact details.
Lead quality: Whether leads turn into customers. Optimize for this, not for the sheer count of leads.
Learning phase: The period after launching or significantly editing an ad set, while Meta's algorithm figures out who converts. Performance is noisy here — avoid editing daily, it restarts the clock.
Lifetime budget: A total spend cap for the campaign's entire schedule. Requires an end date; Meta paces the spend itself.
Link clicks: Clicks that leave Meta for your website. Cheaper to optimize for than conversions, but optimizing for purchases usually earns more.
Link CTR: Link clicks divided by impressions. The cleanest read on whether your creative makes people act.
Lookalike audience: An audience of strangers who statistically resemble your existing customers. One of the strongest targeting tools once you have real customer data.
Lookback window: Another name for the attribution window: how far back a conversion can be credited to an ad.

M

Manual placements: Hand-picking where your ads appear instead of letting Meta decide. Useful when creative only fits certain formats.
Marketing API: Meta's official programming interface for managing ads. It's what tools like Bridge24 are built on — the same rails as Ads Manager, minus the 400 buttons.
Media buyer: The specialist agencies bill you for. Their day-to-day setup work is what Bridge24's wizard does in minutes.
Messenger ads: Placements inside Messenger, plus click-to-Messenger ads that open a direct conversation with your business.
Meta pixel: A small script on your website that tells Meta what visitors do — pages viewed, carts filled, purchases made. Without it, Meta optimizes blind.
Metric: Any measured number. Pick the two or three that map to money and ignore the rest until you need them.
Micro-conversion: The small steps before a purchase: add to cart, signup, a video watched. Cheap signals to optimize on early.
Minimum budget: Meta's floor per ad set per day, roughly a few euros depending on setup. Below a realistic budget, learning crawls.
Mockup: A preview of the ad before it runs. Bridge24 shows every placement's real preview before you publish.
MOFU (Middle of funnel): People who know you but have not bought. Feed them proof: reviews, demos, comparisons.
Multi-advertiser ads: Your ad shown in a carousel alongside other brands' ads. Opt out if positioning matters to you.

N

Native content: Ads that look and feel like normal posts. The highest-performing disguise in advertising.
Negative feedback: People hiding or reporting your ad. Meta tracks it and quietly punishes ads that annoy — creative that respects people is also cheaper creative.
Niche: The specific slice of the market you serve. The tighter the niche, the cheaper the relevance.
Non-discrimination policy: Meta's rules banning exclusionary targeting for housing, employment and credit ads. See special ad categories.
North star metric: The one number that best captures the value you deliver. For most advertisers: CPA or ROAS measured against margin.

O

Objective: What you tell Meta you want from a campaign: Sales, Leads, Traffic, Awareness, Engagement or App promotion. It decides who Meta shows your ads to — choose based on the business result, not the vanity metric.
ODAX (outcome-driven objectives): Meta's six simplified objectives: awareness, traffic, engagement, leads, app promotion, sales. Pick by outcome, not by habit.
Offer: What you actually propose: the discount, bundle, free trial or guarantee. A weak offer makes every ad expensive.
Opt-in: Explicit permission to be contacted or tracked. The legal and ethical baseline in Europe.
Optimization goal: The specific event Meta optimizes delivery for inside an ad set: link clicks, landing-page views, purchases. Switching it restarts the learning phase.
Organic reach: The people you reach without paying. On business pages it is small; that is precisely why ads exist.

P

Paid social: Advertising on social platforms, as opposed to posting organically and hoping.
Payment threshold: The spend level at which Meta charges your card mid-cycle. New accounts start low and graduate.
Placement: A specific slot where ads appear: Facebook feed, Instagram Stories, Reels, Marketplace, Messenger and more. Bridge24 previews your ad in all of them before you spend.
Placement asset customization: Using different crops, videos or texts per placement inside a single ad.
Post engagement: Reactions, comments, shares and clicks on a post. Nice signal, weak buying proof.
Primary text: The main copy above your ad's image or video. First two lines matter most — that's all most people see before "…more".
Prospecting: Advertising to cold audiences to find new customers. The growth engine; retargeting only harvests what prospecting plants.
Psychographics: Targeting by attitudes, values and lifestyle rather than age and city.
Purchase event: The pixel or CAPI event that reports a sale with its value and currency. The anchor of every ROAS number.

Q

Qualified lead: A lead that matches who you can actually serve. Sales time is too expensive to spend on the rest.
Quality ranking: Meta's grade of your ad versus competitors for the same audience. Low quality means higher costs — the algorithm taxes boring.
Quartiles (video): The 25/50/75/100% watch milestones. A cliff at 25% means your hook failed, not your product.

R

Reach: How many different people saw your ad at least once. Compare with impressions to get frequency.
Reaction: Like, love, wow. Cheap engagement and a weak buying signal; do not scale an ad on reactions alone.
Reels: Short vertical video on Facebook and Instagram — the fastest-growing placement, and often the cheapest attention available right now.
Rejected ad: An ad that failed Meta's review. Read the policy cited, fix the issue, resubmit. Repeated violations hurt the whole account.
Report: Numbers arranged to answer a question. If it does not change a decision, it is decoration.
Results: Meta's count of whatever your objective optimizes for. Always check which event a result means before celebrating.
Retargeting: Showing ads to people who already interacted with you — visited the site, watched a video, abandoned a cart. Highest-converting audience you'll ever have.
Retention: Keeping the customers you won. The cheaper half of growth, and the part ads cannot fix.
Review (ad review): Meta's automated and human check of every ad before it runs, usually minutes to 24 hours.
ROAS (Return On Ad Spend): Revenue ÷ ad spend. A ROAS of 3 means every €1 of ads returned €3 of sales. The king of metrics — most others exist to explain this one.
ROI (Return On Investment): Profit-based return: (revenue minus all costs) divided by costs. ROAS ignores your margins; ROI does not.
Rules (automated rules): If-this-then-that automations, like pausing an ad set when its CPA doubles.

S

Saturation: When more budget stops bringing more results at the same cost. Time for new audiences or new creative, not a bigger dial.
Scaling: Increasing budget on what works. Raise it gradually (~20% every few days) — doubling overnight can knock an ad set back into learning.
Scroll-stopper: The visual hook that interrupts the thumb. The first half-second of your ad's life decides the rest.
Seasonality: Predictable demand waves: Q4 gifting, January fitness, summer travel. CPMs ride the same waves.
Segmentation: Splitting audiences or customers into groups that deserve different messages.
Server-side tracking: Sending events from your server instead of the browser. On Meta, that is the Conversions API.
SKAdNetwork: Apple's privacy framework for app-install attribution on iOS. Aggregated, delayed, and the only game in town.
Social proof: Evidence that others trust you: reviews, customer counts, logos, user content. The strongest single lever in ad creative.
Special ad categories: Housing, employment, credit and political ads, which get restricted targeting options by law and policy.
Spend: What you've paid Meta for delivery. In Bridge24 you always see it live, next to what it bought you.
Sponsored: The label Meta puts on every ad. Everyone sees it; native-feeling creative wins anyway.
Stories: Full-screen vertical photos/videos that disappear after 24 hours — as a placement, cheap reach with a native feel.

T

Targeting: All the choices about who sees your ad: geography, age, gender, interests, custom audiences. Modern rule of thumb: broad targeting, strong creative.
Test budget: Money earmarked for learning rather than immediate return. Typically 10 to 20% of spend.
Testimonial ad: A customer's own words as the creative. Screenshot-style testimonials are quietly excellent.
Third-party data: Audience data bought from brokers. Fading fast for privacy reasons; first-party data wins.
Thumbnail: A video's cover image. It decides whether the video ever gets a chance.
TOFU (Top of funnel): Strangers. Entertain and intrigue; do not propose marriage on the first scroll.
Tracking: Measuring what happens after the click, via the pixel and Conversions API. No tracking, no learning — for you or for Meta.
Traffic (objective): Optimizing for clicks or landing page views. Good for warming up a pixel, a poor proxy for sales.
Trust signals: Guarantees, secure-payment badges, return policies. Reduce perceived risk right next to the CTA.

U

UGC (User-generated content): Real-people style content filmed on phones. The dominant winning ad format of this decade.
Underdelivery: Spending less than the budget because the audience is too small or the bid too low.
Unique clicks: Clicks counted once per person, however many times they tapped.
Upsell: Offering a bigger or better version at the moment of purchase. Raises AOV and quietly subsidizes your ads.
Urgency: A real deadline or limited quantity that gives people a reason to act now. Fake urgency reads as noise.
UTM parameters: Tags added to your link (?utm_source=facebook…) so your analytics knows which ad brought each visitor. Free attribution — always use them.

V

Value proposition: Your one-sentence answer to why buy from you. If it is fuzzy, no targeting will save it.
Vanity metric: A number that flatters but does not pay: followers, likes, raw impressions.
Verification (business verification): Proving your business identity to Meta. Required for some API access levels and features.
Vertical video: 9:16 video filling a phone screen — the format Stories and Reels demand. Horizontal video in a vertical slot is money on fire.
Video completion rate: Completions divided by plays. Measures how well the content holds attention after the hook.
Video views: Counted generously (3 seconds counts). Watch "ThruPlays" and completion rates if you want the real picture.
ViewContent: The pixel event fired when someone views a product or key page. An early-funnel signal worth tracking.

W

Warm audience: People who already know you: past visitors, engagers, subscribers, previous buyers.
Watch time: Total time people spent watching your video. The algorithm's favorite currency.
WhatsApp ads: Click-to-WhatsApp ads that open a chat with your business. Huge in markets where WhatsApp is the default channel.
Whitelisting (creator licensing): Running ads through a creator's own handle with their permission. Their face, your budget.
Winning creative: The ad variant that beats the others on your KPI. Find it by testing, then give it the budget — most accounts make their money on one or two winners.

X

XLSX / CSV export: Getting your raw numbers out of the platform for your own analysis or your accountant.
XML product feed (catalog): A structured file listing your products (names, prices, images) that Meta ingests to run dynamic catalog ads — each shopper sees the products they actually browsed.

Y

Yield: Revenue per unit of spend or attention. The optimizer's lens on every placement and audience.
YoY (Year over Year): Comparing a metric with the same period last year — the only fair way to judge seasonal businesses, where month-to-month swings mislead.

Z

Zero-click content: Posts that deliver full value without asking for a click. They build the warm audience your ads later harvest.
ZIP / postal-code targeting: The most granular geo targeting Meta offers — down to postal codes. Powerful for hyper-local businesses; expensive if the area is tiny.
Zombie campaign: Still spending, long past its best. Audit monthly and pause without mercy.

Now that the words make sense…
