How can i use SEO in my Blogs to be rated first?

This is interesting. I am trying to figure out SEO and all the hints here have helped me alot...thanks.

It very much depends on what your blog is about, how well it's written, and a number of other factors. Certainly key words help, but they're not the be all and end all. Links to your blog are good, and I'd suggest (in addition to what other people have offered) that you sign up with LinkandBlogChallenge.com They offer a way to gain links quickly and easily.

You can learn SEO just by focusing on your keywords and less graphic usage. You can checkout http://www.SEOmoz.org for more SEO tips.

all you need for top ten is this: www.axandra.com/go.to/allaboutwebtools follow the instructions on top ten optimizer.

As mentioned earlier, trying to get links (inbound) from social sites and forums help. Having consistent quality content and associated keywords, for a niche topic helps to attract and retain visitors. Maybe leave quality comments at blogs that interest you, and leave a link if possible...
