What do D2C marketing and AI search terms actually mean?

Meta's set of automated campaign options, such as Advantage+ shopping campaigns, where Meta's system chooses audiences, placements and creative combinations within the budget, goal and assets the advertiser sets.

Why it matters to an agency. Automation hides which audience or placement produced a result, so when performance moves, the team needs other evidence to explain it to the brand.

Writing and structuring content so it answers a specific question directly, in a form search features and AI assistants can lift as the answer. It overlaps heavily with GEO; the term is older and grew out of featured snippets and voice search.

Why it matters to an agency. Buyers increasingly read the answer rather than the list of results, so content that answers the question in its first lines is the content that gets used.

AI-generated summaries that Google shows at the top of some search results, with links to the pages they draw on. Google Search Console includes their impressions and clicks in its search performance data.

Why it matters to an agency. A brand can lose clicks while its rank holds, because the answer is read before the links, so the team needs to know whether the brand's pages are the ones cited.

The share of AI answers, across a fixed set of buying questions, that name a brand, usually compared with the same share for its rivals.

AI share of voice = answers naming the brand ÷ answers tracked × 100

Why it matters to an agency. It turns AI visibility into a rate an agency can track month to month and report, instead of one screenshot of one answer.

Automatically flagging a metric that moves outside its normal range, judged against its own baseline, instead of waiting for someone to spot the change in a report.

Why it matters to an agency. The agency hears about a drop the morning it happens, before the brand does, while moves inside the normal range stay silent.

The average revenue per order over a period.

AOV = revenue ÷ number of orders

Why it matters to an agency. AOV sets how much a brand can pay to win an order, so a falling AOV can make a steady CPA unprofitable.

The rule that decides how credit for a conversion is shared across the ads and channels a buyer touched before converting, such as last click, first click, linear, position-based or data-driven. ai-dm does not do attribution modelling; it shows each platform's own numbers side by side.

Why it matters to an agency. Changing the model changes which channel looks best without any change in sales, so the team should say which model a number uses before comparing channels.

The period after someone clicks or views an ad during which a conversion can be credited to that ad. Meta's default, for example, is 7-day click and 1-day view.

Why it matters to an agency. The same sale can be counted by two platforms with different windows, so ROAS from Meta and Google Ads can't be compared until the windows are known.

The expected value of a metric for a period, worked out from its own recent history, often for the same weekday or season, and used as the reference for judging whether a change is real.

Why it matters to an agency. Without a baseline, every daily wobble looks like news and real drops get missed. A baseline frozen before a change is also how you check whether that change worked.

A login space where a brand sees its own live numbers, what changed and what its agency did about it, instead of waiting for a monthly report.

Why it matters to an agency. Brands that can see the work between reports ask fewer “what are you doing for us” questions, and the portal carries the agency's name.

A short, versioned statement of who a brand serves, the promise it makes, the proof behind that promise and what it never says, used as the reference for every ad, post and article.

Why it matters to an agency. It keeps a brand sounding the same whoever on the team writes, and gives reviewers one document to check every draft against.

What it costs to win one new customer over a period: acquisition spend divided by new customers. Blended CAC uses all marketing spend and all new customers; ai-dm does not calculate blended CAC.

CAC = acquisition spend ÷ new customers

Why it matters to an agency. CAC against LTV shows whether a brand's growth pays for itself. A platform's CPA is not the same number, because it counts only that platform's conversions.

A link or source reference that an AI answer shows for what it says. A brand can be cited without being named in the answer, and named without being cited.

Why it matters to an agency. Citations show which of a brand's pages AI systems rely on, which tells the team which pages to strengthen and which questions the brand is missing.

Google's three page experience metrics, measured on real visits: largest contentful paint (LCP) for loading, interaction to next paint (INP) for responsiveness, and cumulative layout shift (CLS) for visual stability.

Good: LCP ≤ 2.5 s · INP ≤ 200 ms · CLS ≤ 0.1 (Google's thresholds)

Why it matters to an agency. Slow mobile product pages cost conversions from paid traffic as well as organic, so a speed problem is an ads problem too.

Ad spend divided by the number of conversions it produced, where the conversion is whatever the campaign is set to win: a purchase, a lead or a sign-up.

CPA = ad spend ÷ conversions

Why it matters to an agency. A rising CPA can come from creative fatigue, a pricier auction, a site problem or a broken pixel, and each needs a different fix.

The average amount paid for each click on an ad.

CPC = ad spend ÷ clicks

Why it matters to an agency. It separates traffic getting more expensive from traffic converting worse after the click, which are different conversations with the brand.

The cost of showing an ad 1,000 times. The M stands for mille, Latin for a thousand.

CPM = ad spend ÷ impressions × 1,000

Why it matters to an agency. CPM moves with auction competition and the season, so it helps tell market pressure apart from a creative problem.

The drop in an ad's results as the same people see it again and again: frequency climbs, CTR falls and CPA rises.

Why it matters to an agency. Spotting it early lets the team refresh the creative before budget is spent on an ad people have stopped noticing.

The share of ad impressions that led to a click.

CTR = clicks ÷ impressions × 100

Why it matters to an agency. A falling CTR on the same audience usually points at the creative or the offer, not the budget.

The share of clicks or sessions that end in the goal action, such as a purchase. Ad platforms usually divide by clicks; GA4 usually divides by sessions or users.

CVR = conversions ÷ clicks (or sessions) × 100

Why it matters to an agency. When CTR holds but CVR falls, the problem is usually after the click: the landing page, price, stock or checkout.

A dated record of each marketing decision for a brand: what was changed and why, the metric it was expected to move, that metric's baseline before the change, who approved it and what happened.

Why it matters to an agency. It shows the brand what worked, and it keeps the reasoning when someone on the team leaves.

The qualities Google's search quality rater guidelines use to judge whether content is helpful and reliable, with trust treated as the most important. It is a framework for human raters, not a single ranking score.

Why it matters to an agency. Named authors, first-hand detail and clear sources make a brand's articles believable to buyers, to Google and to the AI systems that cite them.

A distinct, identifiable thing, such as a brand, person, product or place, that search engines and AI systems recognise and link to facts about it, rather than treating it as a string of keywords.

Why it matters to an agency. When a brand is a clear entity, with consistent names, details and markup across the web, AI answers are more likely to describe it correctly.

The chain from a reported number back to the raw record it came from: the platform, the account, the date range and how the metric was counted.

Why it matters to an agency. It turns “trust us” into “check it”, and it shows why two platforms disagree when they do.

The average number of times each person saw an ad over a period.

Frequency = impressions ÷ reach

Why it matters to an agency. Rising frequency with falling CTR is a common early sign of creative fatigue, especially for a brand with a small audience.

Google's analytics platform for websites and apps. It records events such as page views, add to carts and purchases, groups them into sessions and users, and applies its own attribution settings.

Why it matters to an agency. GA4 is often the referee between Meta and Google Ads, yet it disagrees with both, so the team needs to know how each one counts before quoting any of them.

Work that makes a brand's content more likely to be used, named and cited in answers from generative AI systems such as ChatGPT, Perplexity, Gemini and Google's AI Overviews.

Why it matters to an agency. Buyers ask AI assistants which brand to choose. If a brand is never named, it isn't on the shortlist, however well it ranks in search.

A brand's map ranking for one keyword, checked from many points on a grid laid over its area, because local results change with where the searcher is.

Why it matters to an agency. A single rank check from the office hides the streets where the brand drops out of the map results.

Google's free business listing shown in Search and Maps, with the address, opening hours, photos, posts, products and reviews.

Why it matters to an agency. For a brand with a store, showroom or service area, the profile drives calls and direction requests, and an outdated one quietly loses them.

Google's free tool that shows how a site performs in Google Search: the queries it appears for, impressions, clicks, average position, indexing, and reports on rich results and Core Web Vitals.

Why it matters to an agency. It is the only first-party record of what people searched before they reached a brand's site.

The results a campaign caused that would not have happened without it, measured by comparing a group that saw the ads with a similar group held out from them, as in a lift test or a geo holdout.

Why it matters to an agency. Platform-reported conversions include people who would have bought anyway, so incrementality is how a brand learns what its spend actually added.

A proposed convention, first published in 2024, for a Markdown file at a site's root (/llms.txt) that gives large language models a short guide to the site's most useful pages. It is not an official standard, and the major AI search providers have not said they rely on it.

Why it matters to an agency. It is cheap to add, but it should be offered to a brand as housekeeping, not as a way to rank in AI answers.

The block of map listings, usually three, that Google shows for searches with local intent, such as “furniture store near me”, above or among the regular results.

Why it matters to an agency. For local searches the pack takes the clicks first, so a brand outside it is often not seen at all.

The total revenue, or better the gross margin, a customer brings across all their purchases over a set period. Simple versions multiply AOV by the number of purchases per customer.

LTV = AOV × purchases per customer (over the period)

Why it matters to an agency. LTV sets how much CAC a brand can afford, and a brand with strong repeat buying can bid harder for a first order.

A brand's total revenue divided by its total marketing spend across every channel for the same period, sometimes called blended ROAS. ai-dm does not calculate MER; it shows each platform's own ROAS side by side.

MER = total revenue ÷ total marketing spend

Why it matters to an agency. Because it ignores which platform claims the sale, MER checks the whole budget in a way no single platform's attribution can inflate.

Google's product results where a shopper can buy, shown in Search, the Shopping tab and Images with price, availability and shipping. They draw on product structured data on the page or a Google Merchant Center feed.

Why it matters to an agency. Product markup errors can drop a brand's products out of these listings without any warning in its ad accounts.

A Google Ads campaign type that runs one campaign across Search, Shopping, YouTube, Display, Discover, Gmail and Maps, with Google's automation choosing where ads show from the assets, budget and goal provided.

Why it matters to an agency. It reports less detail by channel, so the team has to dig to see whether it is taking budget from the brand's own Search campaigns.

A 1 to 10 rating Google Ads gives each keyword, based on expected CTR, ad relevance and landing page experience. Google describes it as a diagnostic tool, not an input to the auction.

Why it matters to an agency. A low score tells the team which of the three parts to fix, which often lowers what the brand pays per click.

Search results with more than a title and a link, such as star ratings, price, availability or images. Pages usually qualify through structured data, but Google decides when to show them.

Why it matters to an agency. Rich results take more space and attention on the results page, and broken markup removes them without warning.

Revenue credited to ads divided by the ad spend that produced it, usually as reported by each ad platform under its own attribution settings.

ROAS = revenue ÷ ad spend

Illustrative example30,000 in credited revenue on 10,000 of ad spend is a ROAS of 3, often written 3×.

Why it matters to an agency. It is the number most brands ask about first, and each platform works it out its own way, so the team should always say whose ROAS it is quoting.

Code added to a page, usually JSON-LD using the schema.org vocabulary, that describes what the page is about, such as a product, its price and reviews, an article's author or the organisation, in a form machines can read.

Why it matters to an agency. It is how a brand's product details reach rich results and merchant listings, and it helps AI systems read the page correctly.

In Google Ads, the impressions an ad received divided by the impressions it was eligible for. The share it missed is reported as lost to budget or lost to rank.

Search impression share = impressions ÷ eligible impressions × 100

Why it matters to an agency. It tells the team whether a brand is missing searches because of budget or because of ad rank, which lead to different recommendations.

Sending conversion events to analytics and ad platforms from a website's server, rather than only from the visitor's browser. Meta's Conversions API is one example; it usually runs alongside the browser pixel, with an event ID so the same conversion isn't counted twice.

Why it matters to an agency. Browser restrictions and ad blockers drop some events, so platforms see fewer conversions and optimise on less data. Knowing how a brand sends its events explains part of the gap between platforms.

Tags added to the end of a link, such as utm_source, utm_medium and utm_campaign, that tell analytics tools where a visit came from.

Illustrative example?utm_source=meta&utm_medium=paid_social&utm_campaign=summer_sale

Why it matters to an agency. Inconsistent or missing UTMs are a common reason GA4 can't match the numbers in a brand's ad accounts.

A report an agency sends under its own logo, colours and domain, with no mention of the software that produced it.

Why it matters to an agency. The brand sees the agency's work and name, not a tool it could sign up for itself.
