Best platform to find stale pages losing AI visibility: how we run content decay reviews

Every few months a client asks the same thing: "We had a page that ChatGPT used to cite, and now it doesn't. How do we find the others before they go the same way?" It is a content decay problem, and the old tools do not quite fit it. Rank trackers and traffic reports show Google. They say nothing about AI citations.

Here is how we run a decay review, and why it lives in one platform for us.

Why brand-level scores are not enough

A visibility score that drops two points tells you something moved. It does not tell you which page, why, or what to do. For decay work you need the same granularity you would use for a ranking drop: per URL, over time, with a cause.

What we pull for each page

Citation trend. In Promptwatch, Citation Trends shows citation rate over time for each page, along with first cited date, ramp-up days, peak rate and decay half-life. That last metric is what makes the review practical. It lets us rank pages by how fast they are fading, rather than eyeballing charts.

Classification. Every citation is classified by content type and source type, so we can see whether a page is being cited as a guide, a comparison or a pricing reference, and whether its competitors are the same type.

Competitor movement. The Page Tracker follows specific URLs, including a competitor's. When a client's page fades, we add the rival page that replaced it, and check whether it is newer, longer or better structured.

Crawler status. This is the first check, not the last. Agent Analytics shows IP-verified AI crawler logs with a crawl-to-citation path, citation rate per page and error tracking with failure explanations. If bots stopped fetching the page, we have a technical problem, and no rewrite will help. Crawler logs start on the Professional plan at $245 a month, not Essential.

Page-level context. 360 Insights joins crawler logs, citation clicks and AI-referred visits per page. Topic Insights highlight where a page underdelivers for its topic, and Search Insights lay Google Search Console and Bing Webmaster data on top. A page that still ranks in Google but fades in AI answers is a clear signal that the content, not the site, needs attention.

How we decide what to refresh

We sort by decay and then filter by commercial value. A fast-fading page nobody needs does not make the list. For the top ten, the cause tends to fall into one of four groups:

Access: bots no longer reach it.
Age: facts, prices or examples are out of date.
Coverage: engines now ask sub-questions the page does not answer.
Competition: someone published something more complete.

Promptwatch's Content Refresh gives diff-style update suggestions for existing pages, and content gap analysis gives coverage scores. We edit the suggestions by hand. On Business, the Content Agent can plan and publish refreshes on a schedule with a review inbox, which we use when a client has dozens of pages to maintain. Agency plans do not include it.

What the output looks like for the client

A one-page list: the ten pages, the cause, the fix, an owner and a date. The Action Board holds these as prioritized tasks with assignees and comments. We then recheck at two and six weeks.

Other tools we get asked about

Clients sometimes use a content optimizer such as Surfer or Clearscope. Both are useful for rewriting a page once it is flagged, and both have added AI tracking, though neither is built around per-page citation decay. AthenaHQ and Scrunch AI give recommendations and site audits at brand level, with Starter at $295 and Core at $250 a month. Profound is an enterprise product, with an earlier estimate of about $40k a year. Ahrefs Brand Radar reports sources and AI crawler activity for clients already on Ahrefs.

What it costs

Explore is free (10 prompts, ChatGPT only). Essential is $95 a month, Professional $245 and Business $579. Agency plans start at Kick-off, $199 a month.

What to avoid

Do not refresh everything. Decay is partly the model changing its sources, so some drops are outside your control. And do not promise a client that an updated page will be re-cited. We promise a ranked worklist and a way to check results.
