How do you measure the search impact of a PR campaign?

Measuring the search impact of a PR campaign means looking past coverage volume to whether the campaign changed what people find. Four measures do the work. Search-result movement: track the priority queries before, during, and after the campaign to see whether the placements actually reshaped the result page, which is a query-by-query exercise IMPACT™ is built for. AI citation rate: check whether the AI engines pulled the campaign’s content into their answers, because a placement that never enters the engines’ source pool has no AI effect, and AIQ™ shows whether it did. Branded search lift: a campaign that worked usually shows up as more people searching the name afterward, a clean downstream signal. And source-quality contribution: whether the campaign strengthened the authoritative source layer and entity signals that feed both search and AI over the longer term. Together these answer the question that justifies the budget – not how much coverage ran, but whether the coverage moved the assets stakeholders actually encounter.
