How many Backlinks per Web 2.0 without getting caught?

Hi all

So i started building my 2.0 profile for backlinks and i also learn the fact that if there are too many links your site prone to de indexed. So i would like to know how many backlinks you should made from a one 2.0 blog. backlink should be for specific post or to entire website? and if you can more than one link how often you should add posts to the 2.0 to not get caught by google?

thanks in advance for replies

One backlink from one web 2.0 property. Anything beyond that does not make sense at all. Google doesn't really care about regular posting on your web 2.0, you do it for the web 2.0 admins, so that your property won't get deleted.

Yeap, if that web2.0 property is specifically used to help your primary money site to gain ranking or benefits, then perhaps just 1 link should be enough for that, and you do not need to put multiple same links back to your site, as having the same links from the same site on the same page doesn't make sense at all.
You can put other authority links - try linking to other authority sites, just to make your web2.0 look rather natural, but if just linking back to your site, just 1 link will do, in my opinion.

Even better, make few posts and 1 link. It will look like you want to create your hobby site and not a just backlinking machine.

one Backlink is enough from one Web2.0.

1 is enough, get more links from different properties each. To answer your question, there is no fixed rule, you can use a separate ip everytime you create an account on the same property.

The most safe is 0.
1 may works or not.
2 is the same as 1, 3 is the same as 2 and so on.
