Reverse Keyword Lookup
In theory, you can use this tool to check any URL (even an opponent's URL) to see which keywords drive traffic to that webpage from the organic (i.e., free) section of Google's search results. However, the lookup feature only reports findings for keywords that it has examined in the past. So, the tool will be more useful if you add keywords now and then check back in the future.

Dynamic Site Mapping
If your website uses form variables to produce dynamically generated content, those results pages are likely invisible to search engines. Dynamic Site Mapping solves this by recognizing the most commonly generated pages and then makes them "spiderable" by creating a search-engine friendly map.

SEOToolSet
Remember the old saying that, "No one ever got fired for buying IBM." There was a general sense that while IBM equipment was necessarily leading edge at all things, at least you could be comfortable that all of its equipment was at least very good. Well, among Search Engine Optimization practitioners, the same could be said for The SEOToolSet by Bruce Clay. Many of the tools offered at BruceClay.com are available elsewhere, in other forms, and sometimes with spiffier features or an easier interface. But the tools in the SEOToolSet are at least very good, well integrated, and convenient, except for the learning curve. (SEOToolSet training is available for an additional fee.)
Bruce Clay's SEOToolSet includes: a competition ranking report, a server page status checker, a keyword selection tool, a keyword density analyzer, search engine submission recommendations, a search engine ranking monitor, a domain ranking report, a ranking report by page name, a ranking report by keyword, and a link analysis tool.
