Hello, can any one tell me if there is a way to make my wordpress blog appear in google's blog search?.... Thanks
you really cant do anything for that, just focus on building quality backlinks and google will do the needful on its own.
There are few Wordpress plugins which will be handy. Specailly SEO All in One plugin and Google XML sitemap plugin. Also use Tags and good category names. Also use SEO friendly permalinks.
But can you benefit from this (money wise?)? I thought wordpress didn't allow ads on wordpress.com blogs? Or are we talking about a hosted wordpress account?
I think that your wordpress blog automatically pings google blog search, so after some time it may appear there.
