Overview
Product summary
Review the store description, core capabilities, and common use cases.
SEO Checker is an easy to use browser extension designed to help you optimize your website's SEO, page speed, and security. It efficiently scans thousands of pages on your site, pinpointing issues and providing clear guidance on how to fix them.
Here's what SEO Checker checks for you:
- Page Titles & Meta Descriptions: It scans your site's page titles and meta descriptions to identify those that are too long, too short, missing, or duplicated, helping you optimize these critical elements.
- Page Headings: It checks if each page has a unique and properly optimized H1 heading.
- URLs: It ensures your website's URLs follow best practices, making them easy to read and SEO-friendly.
- Content Analysis: It looks for duplicate or thin content, checks if images have proper meta tags, and assesses how well your content works on mobile devices.

A little wonderful jewel that can replace very expensive tools. I love the work of these guys!!!
Very insightful tool! Thanks
This is great! I've had to create my website myself. I had enough knowledge to get things up and running but this tool will be excellent at helping me spot and fix the stuff I wouldn't have been able to identify. Thank you!
Best extension really worth it
What a superb browser extension! This is most definitely one of the best website analytic tools available within the freemium space.
Checked this out, this is wonderful, handy tool for my website! Would love to know how in-depth this will work for YouTube analytics.
Thank for the wonderful tool. As a non-seo fan I got a lot of insights to our sites in double quick time. Motivated me to learn SEO and help our websiste staff! Simple and reliable.
I just crawled my website and the info returned was fast. The interface is user friendly and I received A LOT of information that I can see where I am good and where I need to make tweaks! I will be using SEO Checker going forward!
Very slow. Screaming Frog is faster and much more comprehensive.
Excellent tool! Clean and intuitive. Will be using this tool from now on. Congrats!!
