1. Don’t put your blog at the root of your domain.
2. Name your directory ‘blog’ instead of ‘wordpress’.
3. In URLs, no spaces are worst, underscore are better, dashes or hyphens are best.
4. Use alt tags on images: not only is it good accessibility, it’s good SEO.
5. Include keywords naturally in your posts.
6. Make your post dates easy to find.
7. Check your blog on a cell phone.
8. Use partial-text feeds if you want more page views; use full-text feeds if you want more loyal readers.
9. Blogs should do standard pings.
10. Standardize backlinks (don’t mix www with non-www).
11. Use a permanent redirect (301) when moving to a new host.
12. Don’t include the post date in your URL.
13. When moving between hosts, wait until Googlebot and traffic begin to visit the new host before taking down the old one.
14. If using AdSense, use section targeting.
15. Use FeedBurner’s MyBrand feature to take control of your feeds (i.e., feed.domain.com instead of http://feeds.feedburner.com/domain).
