Attributing PR Campaigns to AI Answers
Coverage and a screenshot can both be true and prove nothing. A pre-launch design for reading PR against AI answers: fixed prompts, a control group, 90 days.
Issue focusOff-Site Authority: Digital PR, Communities, and the Knowledge Graph
Consider a composite example. The retainer renews tomorrow. The agency sends a deck: eleven placements across outdoor and business press, two screenshots of a gear site’s homepage. The growth lead opens a chat log instead — one buyer question, “portable power station for a van conversion that runs a 500 W fridge overnight,” asked three times a week apart. Four brands come back each time; theirs appears once, as “a solid budget option.” Both documents are true. Only one answers whether the retainer worked.
PR earns GEO credit only when an answer moves inside a prompt set fixed before launch and holds against a control group; coverage proves the pitch landed, not that a model read it.
Four handoffs, and coverage measures one
A placement reaches an answer through four stages: published, independently crawled, rewritten by a third party, assembled into an answer. Coverage counts the first; the rest run on someone else’s clock.
A release on a syndication site sinks in days; the same study on your own domain, with a methodology page, data table, and update date, gets re-fetched for months. The third handoff is where value appears: a reporter or community writer takes your numbers and builds their own argument — what citable assets are for. The fourth is assembly: one article often contributes a clause of context, sometimes only that the brand exists.
A placement can surface a month later, and no single one supports “AI recommends us now.” Ask which handoff moved, and where next quarter’s budget goes.
| Layer | What it measures | Data source | Common misuse |
|---|---|---|---|
| Reach | Whether the story ran | Placement links, media list | Reported as the result |
| Corpus | Whether it was crawled and rewritten | Citing domains, third-party articles, crawl logs | Syndication counted as independent |
| Answer | Whether it appears, is cited, is recommended | Repeated samples of fixed prompts | “It appeared,” no position or citation |
Noise that looks like lift
Answers move on their own: another metro, account, or week, and the brand list changes. Much of a visible campaign gain is that churn.
Four treatments: repeat every prompt three times and keep only recurring phrasing; keep Black Friday weeks out of the baseline; hold ten category questions you never wrote for as a control; stagger paid social and creator drops, and say so when they cannot be separated.
Read the control first. If it rose as much as the test group, subtract it; if it fell while the test group rose, the signal is harder to explain away.
The brief that makes attribution possible
Attribution is an agreement made before launch, not arithmetic after it.
| Step | Action | Owner | Passes when |
|---|---|---|---|
| 1 Lock the set | 20 buyer questions from tickets and site search, plus 10 controls | Growth, content | Each maps to a page or competitor |
| 2 Store a baseline | Sample 14 days out, three runs each, save text and cited domains | Growth | One prompt’s spread is visible |
| 3 Log the corpus | New citing domains, third-party articles on your data, crawl hits | Content, technical | Every domain has a first-seen date |
| 4 Read | T+30, T+60, T+90 — same account, region, wording | Growth | Test and control in one table |
| 5 Report | Three lines of conclusion, one page of detail, one next action | Lead | A decision in five minutes |
Step 3 is the one teams skip and the one that explains causality: a citing domain usually appears before the answer changes, so skipping it credits the campaign’s last week for a rewrite that entered the corpus two weeks earlier. Log it as citation monitoring does, with one entity ID across links, mentions, and citations.
Example: one data campaign, four readings
Example — brand, figures, and campaign are invented; read the time series, not the numbers. A DTC brand runs a camping power survey with a methodology page, data table, and three expert commentaries: twenty test prompts, ten controls, four sample dates.
| Metric (Example) | T-14 | T+30 | T+60 | T+90 |
|---|---|---|---|---|
| Test prompts naming the brand | 3 | 5 | 9 | 11 |
| Answers citing the brand’s domain | 0 | 1 | 4 | 5 |
| Third-party articles using the data | 0 | 0 | 2 | 3 |
| Control prompts naming the brand | 2 | 2 | 3 | 2 |
Three readings. The 3-to-5 move at T+30 sits inside the control’s 2-to-2 spread: noise, not results. The inflection is T+60, as third-party articles go 0 to 2; that timing explains more than the count. T+90 flattens — corpus accumulation has a ceiling, so the next round needs a new data point, not another mailing.
Three lines, one page
Two audiences. For whoever funds the next round: which layer moved, whether it separates from control, where the budget goes. For the team: prompt text, sample time, answer text, cited domains, a verdict — new, gone, reworded. Keep mention, citation, and recommendation as separate counts, as the three layers of off-site authority do.
Do not report the test group alone; do not merge “mentioned” with “cited,” the difference between being in the room and being the source; do not claim a lift without the control’s same-period change; do not turn one sample into a finding.
Where this breaks
Event PR — funding, a recall, a lawsuit — drowns the signal; unify the message, do not attribute. Campaigns you cannot stagger cost more to separate than the answer is worth; report the total and label it inseparable. In-platform AI and agent shopping barely read press; they read listings, reviews, fulfillment, and feed data, so this covers off-site authority only. One extra mention written up as a lift discredits a small-sample report.
The most common misuse is choosing prompts after the fact, reporting only the questions that improved. That is evidence shopping, and a reviewer who asks for the excluded prompts will find it.
This month, before the next PR calendar is locked, put 20 buyer-voice questions, 10 controls, a 90-day window, and three read dates into the campaign brief, and archive one baseline sample before launch. Without it, the post-mortem is another argument. For the dashboard view, start with the measurement hub; for how off-site nodes corroborate one another, open the issue’s off-site trust network.
