Meta Ads glossary

The creative itself. One ad set can carry several, and Meta will quietly favour one of them.

The layer holding budget, audience, placement and optimisation. Where most of the real decisions get made.

Setting budget per ad set instead. More control, slower learning, and the right choice when you need guaranteed spend on a segment.

The billing and campaign container. One business can hold many, and mixing objectives across them makes reporting a mess.

One budget at campaign level that Meta spreads across ad sets. The current name for CBO.

Lets Meta look beyond the audience you defined. Your input becomes a suggestion rather than a boundary.

Automatic tweaks to your creative, from brightness to music to text overlays. Test it rather than trusting it, because some changes hurt.

Lets Meta serve wherever it expects the best result. Usually the right default, and worth checking the placement breakdown afterwards.

The current name for Advantage+ Shopping after Meta renamed the objective structure.

Meta automated ecommerce campaign type with minimal manual targeting. Strong with a clean catalog and good creative, opaque when either is missing.

Results split by age band. Often reveals that one band carries the entire campaign.

Meta framework limiting how many events per domain can be reported after iOS privacy changes. Forces you to rank what matters.

Optimises toward installs or in-app events.

The click and view windows used to credit conversions. Changing it changes reported performance without changing anything real.

Two of your own ad sets competing for the same person. Meta suppresses one, and you get less reach for the same money.

Meta serving beyond your defined audience when it expects better results.

Third-party apps and sites Meta sells inventory on. Cheapest CPMs and the placement most worth checking before you trust the results.

How much two audiences share. High overlap means you are paying to reach the same people twice.

Optimises toward reach or ad recall lift. Judged on cost per thousand, never on last-click return.

Running a creator post as an ad from your account with their permission. Keeps the creator credibility and adds your budget.

Little or no targeting beyond country and age, letting the algorithm find people. Now the default advice, and it needs volume to work.

The parent entity owning pages, pixels, catalogs and ad accounts. Set permissions here rather than on individual assets.

The button label. Small changes here move click-through rate more than most people expect.

The older name for the same thing. Meta decides which ad set deserves the money.

What you tell Meta to optimise toward. Pick the wrong one and no amount of budget fixes it.

A hosted setup for the Conversions API that avoids building your own server integration.

Several cards people can swipe through. Good for multiple products or a sequence, and the first card does most of the work.

The product database Meta pulls from. Feed quality decides catalog ad performance more than bidding does.

Ads generated from your product catalog rather than built by hand.

Ads that open a chat instead of a website. Effective where the sale needs a conversation.

The same idea through WhatsApp. Dominant in markets where WhatsApp is the default channel.

A brand advertising through a retailer catalog and getting attributed sales back. Common in FMCG and marketplace selling.

A hero image or video above a grid of products. Strong on mobile, weak in placements that do not support it.

Where catalogs and shops are configured.

A lead objective mode that optimises toward leads your CRM says converted, not toward form fills.

Where the conversion happens: website, app, messaging or on Meta itself.

Server-side event sending that survives browser restrictions. Recovers a meaningful share of conversions the pixel loses.

Results by country. Essential whenever margin or shipping cost differs by market.

Running genuinely different concepts rather than variations of one. Protects against fatigue better than swapping colours does.

The general practice of improving what the ad looks like and says. On Meta this outweighs targeting work by a wide margin.

A list built from your own data: site visitors, customers, video viewers or engagers.

Uploaded emails or phone numbers, matched to Meta profiles. Match rates fall every year.

Whether an ad is running, in review, limited or off.

The smaller line beneath the headline. Frequently hidden depending on placement.

Interest, behaviour and demographic layers. Less useful every year as Meta leans on its own signals.

Results by phone, tablet or desktop.

Proving you own a domain so you control which events it can report. Skip it and your event priority is set by someone else.

Meta mixing your headlines, images and copy into combinations. Good for finding a winner, poor for knowing why it won.

Catalog ads that show the specific products someone viewed. The workhorse of ecommerce remarketing.

Credit for conversions after someone watched a meaningful chunk of video without clicking. Sits between click and view attribution.

People who interacted with your content on Meta rather than on your site.

Optimises toward reactions, comments and shares. Cheap, and rarely connected to revenue.

Meta forecast for a given budget and setup. Wide, optimistic, and useful only for spotting obviously broken configurations.

A score for how well your event data matches Meta users. Low scores mean lost conversions, and adding customer parameters is the fix.

Ranking your eight allowed events. Only the highest-priority one that fired gets reported for iOS users.

Where pixel and conversions API data is inspected. First stop when conversions look wrong.

A list you deliberately keep out, usually existing customers. The simplest way to stop paying for people who already bought.

Ads on Facebook surfaces. Still the deepest targeting data Meta holds, and the oldest audience.

The main scrolling placements on Facebook and Instagram. Most expensive inventory, and usually the best performing.

A limit on how often one person sees the ad. The cheapest defence against creative fatigue.

Results split by gender, where local rules allow it.

The bold line under the creative. Short, and often the only text people read.

Awaiting policy approval. Editing an approved ad restarts this and resets learning.

Ads inside longer video content. Higher completion rates and a more passive audience.

Ads on Instagram feeds, stories and reels. Younger audience, higher creative demands, and usually higher CPMs.

The same for your Instagram profile.

A fast-loading full-screen page inside the app. Useful when your own site is slow.

The current name for lead forms. Add qualifying questions if sales complains about quality.

A form that opens inside Meta rather than on your site. Higher volume, lower intent, and the gap is usually large.

People who opened or submitted an instant form.

Optimises toward form fills or messages. Produces cheap leads and, without qualification feedback, plenty of worthless ones.

A warning that the ad set will never gather enough conversions to stabilise. Usually means the budget or the audience is too small.

The period while Meta gathers enough data to deliver stably. Performance during it is not representative of anything.

Meta signalling that something is holding the ad set back, from audience size to bid caps.

Ads inside Facebook Marketplace. Commercial intent, and a browsing mindset closer to shopping than scrolling.

Placements inside the Messenger app.

Meta advertising platform covering Facebook, Instagram, Messenger and Audience Network from one account.

Where campaigns are built and reported. The tool most of this list lives inside.

The old name for the account and asset container. Now folded into Business Suite.

The wider workspace holding pages, catalogs, pixels and people permissions.

The browser-side tracking snippet. Increasingly unreliable on its own thanks to blockers and privacy changes.

Sales completed by phone or in person, matched back to ad exposure. The fix for lead campaigns that optimise toward noise.

Actions that happened outside the browser, uploaded afterwards.

The specific action the ad set is bidding toward. Choose one with enough volume to learn from.

People who engaged with your Facebook page.

Results by where the ad ran. The fastest way to find out that Audience Network spent a third of the budget.

Results split between Facebook, Instagram, Messenger and Audience Network.

Interactive demo units, mostly for apps and games. Higher intent installs at a higher cost per install.

The copy above the creative. Gets truncated on mobile, so the first line carries the weight.

A filtered slice of the catalog, used to target specific products or margins.

Short vertical video placements. Cheap reach and heavy competition for attention.

Vertical video in the Reels feed. Cheapest inventory Meta sells right now, with the shortest attention window.

Splitting results by a dimension such as age, placement or device. Where averages stop hiding things.

Any warm audience of people who already know you. Great attributed numbers, modest incremental ones.

Desktop sidebar placements. Small, cheap, and largely ignored.

Optimises toward purchases or other conversion events. Needs enough weekly conversions to escape the learning phase.

Ads shown against searches inside Meta apps.

Ads pointing to your Meta shop rather than to your own site.

One static image. Still competitive, and by far the cheapest format to produce and test.

A restricted category covering housing, employment, credit and social issues. Targeting options are cut hard, and lookalikes behave differently.

Full-screen vertical placements. Needs creative built for the format, not a cropped feed ad.

Full-screen vertical placements between stories. Skipped fast, so the first second decides everything.

Optimises toward clicks or landing page views. Useful for testing pages, poor for driving sales.

Bidding toward revenue rather than conversion count. Requires accurate purchase values in your events.

Video creative in feed or stream. Higher production cost, and usually better at cold prospecting than static.

Dedicated video browsing surfaces such as Facebook Watch.

People who watched a set share of your video. A cheap way to build a warm pool when site traffic is thin.

Actions on your website, sent by pixel or Conversions API.

People who visited specific pages, built from pixel data.
