I'm assuming you're aiming your site at people who are new to SEO (the information you provide is pretty basic) so some more info about the results would be useful. For instance:
Title - What is a title tag? Is this important relative to other factors? Why titles should be unique on your site, why the page subject should usually be listed first.
Meta keywords - What this is. Why you may not actually bother, as Google doesn't.
hn - How to structure a page (with reference to standards).
URLs - Examples of what's good and bad, how to set this up in e.g. WordPress, the importance of using dashes (and more recently underscores).
Consider doing more with the results. You provide a list of keywords & densities but don't really say why anyone should care or what you can do with the info. The
SEOmoz Term Extractor seems to do the same analysis, but gives a more detailed breakdown of the page and, to me at least, seems a lot more 'actionable' as a result.
You could also give info on other things that are important for ranking, such as writing good quality content, trusted backlinks & how to attract, getting involved in relevant communities, why it's often good to share, etc. (Just as info, not tools. Though if you could make tools for this, that would be amazing
)
Hope that helps a little, anyway.
PS Your title graphic says 'SEO Bugs' but you use 'bugz' elsewhere.
