Why I am ranking for irrelevant keywords

[BipSum]

My website is e-commerce and used to rank for all industry related keywords like buy widgets, cheap widgets, online widgets in top10.

And suddenly my website was hacked and to resolve this hacking issue i have re-write all my dynamic urls into static pages after that new pages are indexed and ranking well. But after few months i have notice few changes in keywords ranking going down. But suddenly after Google Algo (EMD/Panda) update on Sept 27 i lost all my positions. And then according to Google guidelines i have worked on over optimization and low quality pages. I have removed all tones of low quality pages from SERP and simultaneously worked on url re-write.

But i have notice small percent of changes in keyword positions like when Google Algo (EMD/Panda) is rolled out i lost my keyword positions from 1st page to 200 page and after working on over optimization and low quality pages the keywords are came back to 100 pages.

Recently i have notice that my web pages ranking for irrelevant keywords. For example, let's say i used to rank for home page for these keywords; buy widgets, cheap widgets, online widgets but now am ranking for different inner pages say (guide pages).

Can any one suggest me whats wrong..

Hi Irving Weiss,

Thanks for reply.

What type of penalization? And now i am ranking for guides pages for main keywords.

Could you please suggest us how to resolve this?

you were penalized, so now your main pages don't rank for your main keywords, only your inner pages are ranking for keywords which aren't your main keywords. If you're penalized you won't rank for those anymore until you fix the issue so you're probably seeing the others you are ranking for surface.
