Should I Create WEB 2.0?

Web 2.0 is good. You should create it for your website.

In my experience web 2.0's serve two purposes.

1. Link them to your money site and use URL, branded, or generic anchor texts - diversifying your anchor text profile.
2. Link them to your PBN or guest posts and blast them with cheap links - use as a buffer site.

In my experience they will only help a very low completion keyword rank when used alone.

It's also true many web 2.0's will not index. Most web 2.0's will need backlinks pointing at them before Google will index them and keep them in the SERP.

I've noticed linking out to a lot of different relevant places to your link really helps the page get indexed.

Place 3-5 links out on your WordPress. Com anyway for much better indexing rates
