I host my own site and use the Cutline2pt1 theme. I've made few mods to make the Title and Masthead more keyword specific. I use "Simple Tags" and "Google XML Sitemap" plugins for SEO. I've also edited the header.php and footer.php files for SEO and Google Analytics. I use "Akismet" to filter occasional spam.
I've registered with Google and ping the usual suspects upon posting. I get a good number of vistors/hits per day for some dumb hillbilly with a computer. The raw logs show over 3000 unique IPs visiting in the past three months - plus 100 plus spider hits a day. I don't get paid for visits or clicks so that seems pretty good to me.
If you have time and are into investing, please take a quick look at my site. Any suggestions of format will be appreciated.
