Introduction

A page can accidentally become noindex after an update. A canonical URL can change. Schema markup can disappear. A redirect can start pointing outside your site. Your robots.txt or XML sitemap can change without anyone noticing.

SEO Sentry catches these changes.

How it works

1. You choose the pages to monitor.
2. The first successful check of each page records a baseline of its SEO elements.
3. Every later check compares the page with that baseline.
4. Each difference is recorded as a finding, graded critical, warning or info.
5. Qualifying findings are sent to you in one email digest per check run.

On top of individual pages, SEO Sentry runs site-wide checks on robots.txt, the XML sitemap, AI crawler rules and WordPress search visibility.

What SEO Sentry is not

• It is not an SEO plugin. Keep using your SEO plugin to manage titles, descriptions, canonicals, schema and sitemaps.
• It never changes anything. SEO Sentry does not rewrite titles, change canonicals, edit robots.txt, modify schema or change indexing settings.

It works alongside your SEO plugin, theme, page builder, structured-data setup and sitemap system. If any of them changes an SEO-relevant part of a monitored page, the next check records the difference.
