Ok...I will throw another tool into the ring for marketing blogs...
http://www.pingomatic.com
You use it to "ping" the major blog directories when you update your blog with new posts...and this can help you gain additional traffic.
Also...
There is a sort of secret to doing the same thing with Google sitemaps...
Submit your RSS feed as a Google sitemap, and Google will visit your blog more often to look for new content. Make sure if you use this, that you do update your blog often...or Google will not visit as much.
But that is not all to this secret...
After submitting your RSS Feed sitemap, use the format below in your address bar...substituting your blog address and RSS feed extension where I have bolded:
http://www.google.com/webmasters/sitema ... p%3A%2F%2Fprofitablebusinessedge.blogspot.com%2F
atom.xml
Save this newly created link into your favorites...and every time you update your blog, click on this new link in your favorites...and you will tell Google's bot to search your blog.
Automatically.
Well, I know this was a little technical, and I am not good at explaining tech stuff...but I hope someone can use this.
This trick increased the traffic to my blog three times over.
Enjoy.
