Matt Cutts of Google shared some SEO tips that may help improve the ranking of your blog in Google and other search engines.
Keyword relevance – Choose words users are likely to type, and include them naturally in blog posts. For example, a blogger can use name variations referring to the same device: usb drive, thumb drive, flash drive, pen drive.” Cutts recommends ALT attributes.
URL structure – WordPress default URL structure uses question marks and numbers, instead of day and name, month name, etc.. Cutts says these types of URLs improve aesthetics, usability, and forward-compatibility. For URL paths with keywords in them, Cutts says dashes (hyphens) are preferred over underscores to separate words, but no spaces between words is a bad idea (example.com/my-keywords).
