I keep reading that the SEO will be much better if you have a self-hosted wordpress.org blog versus a wordpress.com blog.
The main concepts that I know of in SEO are:
- Relevant keywords in the text of the article
- sites linking to your sites with the same keywords
- h1/h2 tags
- Relevant title
- Relevant URL
- meta tags
Now as far as I know 1-5 are catered for with a wordpress.com blog. On top of that its set up for making Google/Bing find you. So a wordpress.com blog will automatically submit all your posts to all the search engines - you have to install all your own plugins for wordpress.org and there's no guarantee you're doing it right.
I realise this question is similar to the one on SEO Implications of blog on site versus offsite?. I think that shows that 2 is no different whether is wordpress.com/.org
[Edit] Further to this I've found the Google statement that they ignore the meta keywords tag, so its only the meta description tag that can be added with a wordpress.org SEO plugin.
So does anyone have some (preferably quantifyable) reasons why the SEO should be so much better on wordpress.org?
