Some of my favorite optimization tools

Here's a list of some of my favorite optimization tools:

• Ranking Check: www.rankingcheck.com - allows you to check the SERP values for 3 keywords. The check runs on a single domain. You can also store up to ten keywords for free that Ranking Check will track for free.
• Dig Page Rank: www.digpagerank.com - shows the actual Pagerank for a website from up to 700 DC's (data centers). Shows faked Pagerank also.
  
• SEO Moz Page Strength tool: www.seomoz.org/page-strength - shows an interesting set of data for a website including the Pagerank, link information, domain age, and a Page Strength value that they calculate for you. Very nice tool to see data in an aggregate form without having to go to many different sites. (If PR goes away, I see a tool like this becoming very popular)
• Backlink Watch: www.backlinkwatch.com/index.php - get a list of backlinks to your website.

I'll be back with more later.
