Free Open Sourced AdSense Tracker & Other SEO Tools

AdSense Logger:
[edit: site turned to spam, link to site removed]. I have not tried it and do not know the owner. I do not recommend AdSense Logger. Instead try our free AdSense tracker which integrates with Google Analytics.

Rapid Keywords:
a keyword tool I missed in my monster keyword tool post...will probably add it soon. similar to lots of the ones like AdWords Analyzer or Keyword Locator, but also offers a few additional ways to gather the keywords from (like scraping Google Suggest) and a few formatting tools.

SEO Tools in Perl:
Not sure if these are any good, as I don't code, but here are some Perl codes related to: Overture search term suggestion tool & PageRank. Some people have also mentioned that the PageRank checksum is also an easy find in the Google FireFox toolbar.

FeedPlex:
XML feed search engine

Feedalicious:
Free search engine friendly, randomized RSS content for your pages...hmm, I didn't know something could be both random and search engine friendly.

I don't like the idea of getting locked into a free system which could likely start charging. plus its really a big risk to trust someone else to throw random content in your site without occassionally throwing in something a little extra.

As the price of random [and targeted] content generators decreases and search spam generator product sophistication increases you can expect search engines to place more weight on user feedback and linkage data.

Philanthropix:
Making philanthropy more efficient. I do not know much about them, but the idea sounds cool.
