Monitor SEO changes after launch with an AI agent and MCP

Run the workflow

1. 1. Choose a small set of production pages

   Start with your homepage, main service or product page, and an enquiry page. Record the intended canonical URL for each. A watch observes one public URL; it does not crawl an entire website or measure your rankings. Avoid adding private pages or URLs containing access tokens.

2. 2. Create a baseline and read it before waiting

   Connect the Page Watch MCP endpoint and call watch_page with the URL and a frequency your plan supports. It runs an initial check so later checks have something to compare with. Free currently supports weekly checks; daily checks depend on your plan. Read the returned baseline and actual frequency. Existing baseline problems need attention now: change alerts do not replace that review.

3. 3. Confirm alerts and review the schedule

   Confirm your ToolCargo account email to receive change alerts. Use list_watches to review the last state and next check; manage the same watches in the browser on Watched pages. Due checks run through the hourly job. A daily or weekly schedule can miss a temporary problem between checks, so choose a separate continuous monitoring service if your operation needs minute-by-minute coverage.

4. 4. Investigate changes using evidence

   Use watch_history for the affected page to read changes and recoveries, including a new noindex directive, a changed canonical, Googlebot blocking or an HTTP error. Review linked saved audit reports when history is enabled. Compare the observed value with the intended production setting before asking your developer to change it. A canonical change can be deliberate; the alert itself does not decide whether it is wrong.

5. 5. Recheck the fix and keep indexing separate

   After deployment, run audit_page on the affected URL to verify its current response and HTML. Check Google Search Console separately for Google crawling and indexing. Keep the scheduled watch for future changes; a recovery appears when a later check observes it. For HTTP and TLS monitoring, use watch_uptime on the separate Uptime & SSL endpoint, then review list_uptime and uptime_history.

What a useful result looks like

Illustrative incident note, not a live tool result: a watched pricing page changes from noindex absent to noindex present after a release. Record the watched URL and detection time, inspect the current robots meta tag or HTTP header, compare it with the intended production configuration, and assign a fix. Re-run audit_page after deployment, then check Google separately. For a planned canonical change, record the new intended URL instead of automatically reverting it.

Know the limits

Page Watch checks served HTML without running JavaScript. It is a scheduled comparison of audit signals, not arbitrary text-change detection, a full-site crawler or a ranking tracker. Unreachable pages alert after two consecutive failed checks; bot protection can prevent an assessment. Checks consume the shared Site Audit quota and pause when the monthly allowance is reached. Uptime & SSL Monitor is also scheduled from one server location, not continuous or multi-region. These tools do not edit your website.
