SEO is never stagnant, and it’s more than just the search results that never stand still. Multiple teams are constantly making changes to your site — especially at the enterprise level.

This could be developers, merchandisers, UX team, and plenty more.

Unfortunately, SEOs are usually the last to know about these changes. And these site changes can be detrimental to rankings and traffic long before you even find out about them!

Without knowing about site changes, your SEO strategy can go right out the window.

To overcome this challenge, there are page monitoring tools on the market that can help you catch these site changes as they happen so you can protect your rankings and traffic

Here are the tools we’ll explore down below:


What is an SEO Page Monitoring Tool?

An SEO page monitoring tool crawls and analyzes your web pages and alerts you when a change is detected.

This way, you’ll know what changed and when, so you can mitigate any potential damage to your SEO program.  

Page monitoring also includes monitoring the performance of the page and specific annotations for the changes made. This means you can correlate on-page changes with any performance metric at a page level.

Why is a Page Monitoring Tool Important?

If — or actually, when — other teams in your organization make changes to the site, they probably aren’t thinking about the SEO ramifications.

Instead, they’re making the changes to achieve a goal for their own department. However, they could unknowingly change a critical SEO element that tanks your website's rankings and traffic.

A page monitoring tool will inform you of these changes so you can go in and revert any potentially damaging changes before you lose your search visibility.

Plus, you can correlate everything together and see it in one view. For example, you can pinpoint content changes and show their impact.
