Favorite Google SEO Tools (Free & Paid)

My absolute favorite (can't imagine living without it) is SEO quake, so basic, easy and what a time saver. Free

I use WebCEO all the time and it's a great tool, except for when Google blocks my IP! Paid

I've used tons of backlink checkers, and I think this one is my new favorite: http://www.backlinkwatch.com/ Free

Just searching for a data center checker and I found this one to work the best for me: http://www.seologs.com/dc-rank-check.html and that site has a bunch of other good, easy to use tools that haven't had errors for me.

What are some of your favorite Google SEO tools?

Please share

I use WebCEO too and i think is great tool.

www.seochat.com/seo-tools/ have some good tools but do not know why the site probably is down today
hope seochat master can be aware and fix it soon

We have a free backlink checker. It is here:

seopro DOT com DOT au/free-seo-tools/link-checker/

(I haven't posted enough yet to make it a link)

It checks for Homepage PR, Linkpage PR, Robots.txt, Nofollow, Outbound Links Count, Anchor Text, Anchor Type (text, image or image with alt), RSS, Frames and Broken Links. You can sort all columns in descending or ascending order and output results to CSV.

You can check one URL or the whole site. And you can check display it 100 results per page, or up to 1000 on the page.

Oh, and our PR and Nofollow columns actually work! (LOL Backlinkwatch) ;)
