Hello, I want to start writting a blog for SEO purposes and wondering which of the many different blogs index the fastest in google. thanks.
I don't think any particular blog software is going to matter much, but using WordPress and making certain you PermaLinks are search engine friendly will be about 90% of the solution. The most important think about SE friendly is staying consistent - once you set up an internal structure - keep it! So, I would worry more about that.
Blogger blogs get indexed very quickly but who wants to have a blogger blog. If you read a few threads here on DP about WP you can make it very seo friendly. Like Phynder said a good place to start would be to change your permalink structure.
If you prefer blog - get your own domain name first, not use blog under blogger - use wordpress for your blog, lightweight, easy to customize and many plug-ins to play around. se friendly and all generated pages passed w3c automatically (except you use some template) - Want to get indexed fast? find link back t your site with PR6+, theme revelant is an option but it's good. good luck with your blog.
