In blogger.com and Wordpress if we post blogs daily, but how it works as SEO point means how we improve it and what to do more for that like directory submissions and all......and how manyh links we can give in one blog??
agreed. use all the tricks around this forum to build links to your blog. If you create optimized content, you should rank high in no time, and if you get a high PR you also end up with a valuable backlink. Also make sure you only target one keyword if you want it to ever rank high.
