i have learned about off page seo in the few months since ive started online and am starting to get the feel for it. ive recently gone back and started digging through my actual on page seo and it could sure use some improvement. my main site is a autoblog run by wprobot. it is a mix of rss news articles, youtube vids, and amazon posts. looking through the source, i can see that there is essentially nothing at all being done with html tags (h1, h2, strong, meta tags etc) or image alt text, or url canonization, or redirects and similar things. have tried searching around but cant seem to find a solid guide to this sort of stuff. mostly just vague "its important to have" type things. any suggestions for onsite optimization in general and especially with wprobot would be great.
