Alexa – owns by Amazon, Alexa uses a toolbar (i.e. spyware) in order to track visitor behavior and rank websites by traffic.
Best Use: Don’t install the toolbar, instead go direct to Alex.com or use the Search Spy Firefox extension to get key Alexa data. Alexa ranks websites in reverse order (the lower the number the more traffic).

SEO Browser – See your site the same way a search engine sees it.
Best Use: Not a great tool, but if you are really struggling with ranking, check your site and see if there is something “off” with how your site is being shown to a spider.

Server Header Check – Often your first step in determining issues if your pages are not being indexed or if a competitor is using cloaking.
Best Use: Check competitor URLs and marketing URLs for redirects. See exactly which URL the redirect is going to and which type (301 or 302). I like running any URL that redirects through this tool to understand what process is being executed.

Traffic Estimate – Approximate traffic levels for last 30 days.

Yahoo! vs. Google – Compare by graph the search results in Google and compare with Yahoo!.
Best Use: This gives me a good understanding how different or similar the search engines are for my targeted keyword phrase. Often, if the results are fairly similar, if I get a top ten listing in Google, the same should occur in Yahoo! as well.s
