Gives a ton of SEO info in one area. I usually have to use a few different Chrome extensions that show different areas to get the full picture that this tool gives you upfront.

The domain comparison feature is nice to see a high-level view of how a website sizes up against competitors.

It gives you info on ways to improve the infrastructure of your website.

It’s free for the first 100 pages of the audit.

what are the cons? 

It doesn’t have a sleek or exciting design. It is kinda clunky and not super appealing in color.

The keyword density section is somewhat helpful but gives the density in a percentage without rationale as to what an average percentage is or what the website should aim for.

The high-level parameters are nice to see, but for a new-to-the-tool person, they are confusing and don’t provide a lot of explanation, unfortunately.

 SEO Quake is a good option if you want something quick on your browser to analyze some high-level information about a website.

However, if you want more in-depth analysis, other tools may be better suited for that type of work.
