Mikhail Broun

Project/Product Manager at Serpstat

Our primary goal is to save the time of our users. That's why we've created the Serpstat plugin — the website SEO checker Chrome extension which allows you to find out the key metrics of any site in just a few clicks. Now it is available for Google Chrome, Mozilla Firefox, Opera, and Microsoft Edge!

To examine a domain, you don't need to open the Serpstat site in a new tab. All necessary data is available with one click directly on the site! Read the post to learn about the benefits of the updated Serpstat checker.

If you have the first version of the extension installed, it'll automatically update and won't need any further action.

The updated on-page SEO checker lets you read the Serpstat reports without having to leave the site you are analyzing. Click on the icon and you'll get multiple SEO metrics about a domain or page: visibility, traffic, number of keywords, analyze top competitors in the region, etc.

Let's take a closer look at the information provided by the browser extension.
