I found the following SEO tips highly recommended for start up bloggers who want to improve their blog SERP rank.

• Use h2 tags for your post titles Use h2 tags for post titles, and h3s for sections inside your posts. I use h1 for single page display on this blog though
• Make your post titles into links On archive pages, and on permalink pages, make your post titles link to the permalink page.
• Optimize Page Titles Your title tag should contain more than just your blog’s name, throw-in some keywords. Try this format: “My Cool Post title – TheBlog.”
• Change Your Permalink Structure – If you use WordPress, don’t use the default permalink style! Pick the best option for your purposes, and stick with it. The default ?p=37 permalinks will always redirect to the ones you specifically set.
• Optimize Post Slugs – WordPress, offer a “Post Slug” feature that allows you to tweak the URL of the post. By default permalink URLs are somewhere along the lines of “/2008/02/01/name-of-post/.” Using the Post Slug function, you can change “name-of-post” to something better, SEO-wise. Remove useless words like “of”, “the”, and the like.
• Use Meta Tags – While meta tags don’t have as much value placed on them as they used to, there still is some, and it’s a good idea to use them.
• ALT and Link Your Logo – Make sure your logo links to your blog’s homepage. This is more of a usability thing than SEO advice, but it’s still a good idea. On a SEO note, make sure you use an “alt” tag on the image, adding something such as the blog’s name to it.
