The recent speech of Matt Cutts at WordCamp 2007 (actually as most of the other his speeches) has made pretty much buzz in an SEM society. The session was already blogged many times but we’d like to summarise the “Whitehat SEO Tips for Bloggers”.

• Don’t put your blog at the root of your domain – you could take the advantage of getting twice more links as people link to main page and main blog page
• Consider the words people are searching for and use them in the text of your blog posts in a natural way, without spamming
• Google will not “punish” hard for duplicate blog content but still care about the fact you can get to a post from 3-4 different ways.
• Use short relevant alt tags for all the images you publish in the blog
• Remember Google consider only blogs with multiple authors to be accepted into Google News
• Unlike Yahoo Google does not care about the number of slashes in a URL. Depth of the pages is what Google cares about.
• The SEO Title Plugin is recommended by Matt Cutts for the titles of blog and posts.
• It is not important what file extention you use – .php, .html, .htm, .asp, .aspx, .jsp unless it is .exe
• Underscores and hypens in URLs are treated by Google as word separators
