Ok i don't know much about
seo but i have been using blogpost blogs for affiliate marketing and getting them indexed without problem. Apart from having Unique contents on my blog this is what i go after i have created the blog.
1. I head over to feedburner add my blog
2. After your blog has been added click on publicize and then collect chicklets (i always take the main ones like yahoo, google, aim etc) put the chick lets on your site and click thorugh each one (sign in or register) such that you see your last post.
3. Back on feedburner...collect the headline animator. Copy the code and paste in your blog.
4. Now go to pingomatics (save the site) and ping each time you update your blog. But try not to ping more than once a day.
5. Add your blog to some directories (do a google search)
This is the way i start off and i find my blog soon gets indexed without sweat.
I know there is so much more that can be done...but that above is what i do and my 25 blogs are feeding me fine
You can also use the pingshot offered by feedburner
