I just recently downloaded the all in one seo pack for my blog that has about 800 posts. I am wondering if it will help my search results if I go back through all of my old posts and fill in the SEO sections? Or should I just do this just going forward.
Thanks for the help!
(note: even with all of those posts and constant fresh content, my google pagerank is still zero, so I am trying to do everything to improve this)
