Does it store my pages?

It keeps the extracted on-page fields (such as title, canonical and headings) to compare versions. Monitor allowances depend on your plan.

SEO problems often start with a silent change: a developer removes a canonical, a plugin adds a noindex, a title gets overwritten. Code Monitor watches your pages and tells you when something changes.

Code Monitor lists changes detected on monitored pages such as Title, Canonical, Meta Description, noindex, H1 and Status code — What Code Monitor watches.

What it tracks

Title, Canonical, Meta Description, noindex, robots.txt, sitemap.xml, H1, Status code, Hreflang, Open Graph, Twitter image, Analytics and Tag Manager.

Where to find it

Open Health in your project and select Monitor. Next to it you will find Alerts, Indexation and Link Monitor.

How to use it

Review the changes list, newest first.
Filter to one page to see its history.
Pair it with annotations to connect a change with a traffic movement.
