The export is not the audit. Crawlers flag every missing alt attribute, every long title and every redirect, and rate them all as warnings. Handing that spreadsheet to a developer produces either nothing or a week spent on cosmetic fixes while a template-wide noindex keeps product pages out of Google. The value of an audit is the judgement applied to the export: which issues affect pages that earn traffic or revenue, and in what order to fix them.
Without a baseline, nobody knows if it worked. An audit that does not record clicks, impressions, indexed pages and Core Web Vitals at the start cannot show next quarter whether the fixes helped. Search Console keeps 16 months of performance data, so record your benchmarks inside the audit itself and compare like with like: the last three months against the same three months a year earlier, which removes seasonal swings.
The fundamentals have not been replaced. Google’s own guidance on generative AI search, published in May 2026, says AI Overviews and AI Mode draw on the same core ranking and quality systems as the rest of Search. It states that Google Search ignores llms.txt files, that content does not need to be broken into small chunks, and that no special markup is needed. An audit that checks crawlability, indexation, page quality and helpfulness is already the audit for AI search.
Scope it to what the business sells. A 20,000-page ecommerce site and a 60-page professional services site need the same phases but very different depth. Before crawling anything, list the sections that earn enquiries or revenue and the goal each one serves. Those sections get a full review in every phase; archive pages, tag pages and old campaign pages get a lighter pass. Writing the scope down also stops an audit growing into a site rebuild halfway through the quarter.
Someone has to own the outcome. The audit lead finds the problems, but developers, content editors and whoever manages the Business Profile fix them. This checklist ends with a signed-off fix plan so the work is agreed before tickets are raised, and the next quarterly run opens by checking what happened to the last plan.
