Good things but depend on your blogs if you create multiple blogs in using your site related keywords.
you need to have more pages on your site than your competitors and they need to contain relevant content.
Hi.............I agree with all my DP members but i think you can make multiple blogs for your wordpress website.
mean make many blog to post ariticle ,such as have A.com and i creat my account my.a.com then i can post in MY.A.COM by the same logic
Use a simple template like blogger or wordpress, you could even use your own hostgator hosting to create multiple wordpress blogs
does it boost backlinks to have lots of blogs from wordpress link to your site? has anyone ever done this?
