Paid ads glossary

The terms you see in Ads Manager, Google Ads and your reports, explained without the jargon.

A

A/B test: Comparing two versions of an ad, audience or page while changing only one thing, to find out which one brings better results. It works best when each version gets enough budget and time to collect data.
Ad Rank: The score Google uses to decide whether your ad shows and in which position. It combines your bid, ad quality, expected impact of extensions and the context of the search.
Ad set: The middle level of a Meta campaign. It is where you choose the audience, placements, budget (when not set at campaign level) and schedule.
Advantage+: A set of automated Meta features that let the algorithm choose audience, placements and creative combinations. It tends to work well when the account has the pixel and conversions properly set up.
Algorithm: The system each platform uses to decide who sees your ad, when and at what price. It learns from the conversions you send it, so good tracking makes it smarter.
Attribution: The rule that decides which ad or channel gets credit for a sale. Different tools use different models, which is why Google, Meta and GA4 rarely show the same numbers.
Audience: The group of people your ads are shown to. It can be built from interests, demographics, location, website visitors or customer lists.

Bid strategy: How you tell the platform to spend: maximize clicks, maximize conversions, target a cost per acquisition, target a return on ad spend, and so on.
Broad match: A Google Ads keyword match type that shows your ad for searches related to your keyword, even without the exact words. Powerful with Smart Bidding, risky without good negative keywords.

Campaign: The top level of an ad account structure. It is where you set the objective and, often, the budget.
Click-through rate (CTR): The share of people who clicked your ad out of everyone who saw it. Clicks divided by impressions. A falling CTR usually signals tired creative or the wrong audience.
Conversion: Any valuable action you want people to take: a purchase, a lead form, a call, a booking. It is what your campaigns should be optimized for.
Conversion rate: The share of clicks or visits that turned into a conversion. It tells you how well the landing page and offer work after the click.
Conversions API (CAPI): A Meta tool that sends conversion events from your server or platform directly to Meta. It complements the pixel and recovers data that browsers and ad blockers cut off.
Cost per acquisition (CPA): How much you paid, on average, for each conversion. Ad spend divided by the number of conversions.
Cost per click (CPC): How much you pay, on average, for each click on your ad. Ad spend divided by clicks.
CPM: Cost per thousand impressions: how much it costs to show your ad 1,000 times. It reflects competition for the audience you chose.
Creative: The ad itself: image, video, text and headline. On social platforms it is usually the biggest lever on results.
Custom audience: An audience built from your own data: website visitors, people who engaged with your page or video, or a customer list.

Frequency: How many times, on average, each person saw your ad. When it climbs too high, people tune out and costs go up.
Funnel: The path from first contact to purchase, usually split into awareness, consideration and conversion. Each stage calls for different ads and messages.

GA4: Google Analytics 4, Google's free analytics tool. It shows where visitors come from and what they do on your site, based on events.
Google Tag Manager (GTM): A free Google tool that manages tracking codes (GA4, pixels, conversions) in one place, without editing your site's code each time.

Impression: Each time your ad is shown on screen. One person can generate several impressions.

Keyword: The word or phrase you choose in Google Ads to show your ad when someone searches for it.

Landing page: The page people land on after clicking your ad. It needs to deliver what the ad promised and make the next step obvious.
Lead: A potential customer who left their contact details or asked for information, usually through a form, call or message.
Learning phase: The period after you launch or significantly edit an ad set when the Meta algorithm is still figuring out who to show your ads to. Results tend to be unstable until it ends.
Lookalike audience: A Meta audience of people similar to a source list, like your customers or best leads. It helps you reach new people with a profile close to who already buys.

Negative keyword: A word you add in Google Ads so your ad does not show for searches containing it. It is the main way to stop paying for irrelevant clicks.

Objective: What you tell the platform you want from a campaign: sales, leads, traffic, awareness and so on. The algorithm optimizes toward it, so choose carefully.
Offer: What you are proposing to the customer and on what terms: product, price, bonus, guarantee, urgency. A weak offer rarely gets saved by good targeting.

Performance Max: A Google Ads campaign type that runs across Search, YouTube, Display, Gmail, Maps and Discover from a single campaign, with heavy automation.
Pixel: A snippet of code installed on your site that records what visitors do (views, add to cart, purchase) and sends it to the ad platform.
Placement: Where your ad appears: Instagram feed, Stories, Reels, Facebook, Messenger, Audience Network, YouTube, search results, and so on.

Quality Score: A 1 to 10 rating Google gives your keywords based on expected CTR, ad relevance and landing page experience. Higher scores usually mean lower costs.

Remarketing: Showing ads to people who already interacted with your business, such as site visitors or people who started a purchase and did not finish.
Return on ad spend (ROAS): Revenue generated by ads divided by what you spent on them. A ROAS of 4 means $4 in revenue for every $1 spent.

Search terms report: The Google Ads report that shows the actual searches that triggered your ads. It is where you find new keywords and negative keywords.
Smart Bidding: Google's automated bidding strategies, which use machine learning to adjust the bid for each auction based on the likelihood of conversion.

Tracking: Everything that records and attributes results: pixel, GA4, conversion tags, Conversions API and UTMs. Without it, you are optimizing blind.

UTM parameters: Tags added to the end of a link (utm_source, utm_medium, utm_campaign) so GA4 knows exactly where each visit came from.

Value-based bidding: Bidding strategies that optimize for revenue or conversion value instead of the number of conversions, usually with a target ROAS.
