Web 2.0 is not helping the main site

[cyndey]

I have spent some time to create web 2.0 site. But they are not passing any valued link juice to the main site. What should I do?

Ask yourself this query. Does your web 2.0 sites have any page value? Just creating and putting link of your main isn't just the whole thing. To get link juice first your web 2.0 sites must have some link juice so they can pass.

Don't think of it as a secondary blog. Treat it like another primary one. Build content and get links for it. Then after some time you can link back to your main blog from it.
