I've recently moved my blog, which was hosted on wordpress.com for a year, to my own domain with a custom installation of WordPress. One thing I always liked with wordpress.com was that my blog posts would appear in search engines like Google pretty often, and also many times on the first two result pages.
However, now that I've been posting the first articles on my own domain, I noticed there doesn't seem to be this kind of search engine exposure anymore. I assume this feature is controlled by the corresponding option in the "Privacy" settings, but in both WordPress.com and my own installation, it looks pretty similar.
Does anyone know if wordpress.com does some advanced stuff so that search engines are getting to my blog more often, and if so, is there some kind of plugin or setting that gets a custom installation of WordPress up to par with that?
