Q-1 Where can i find free backlinks?

There are many sources that claim give you freebacklinks but all they are doing is advertising their website by you freely. No one want to advertise anyone without getting anything. in my case i have searched "freebacklinks" several times but all i get was websites that want their links in your website as well.

The best possible solution to get backlinks is to take a part in forum or free web directory.the one good solution is search some forum name that allow user to add links in their forum post. Unfortunately most popular forums didn't allow it to new user.you must be regular and paid user to get this benefit.

Fortunately, I find some Forums that allow you to make your blogs and forum topics with links.you may need to register but its useful than other websites that want link back from your website.
List are below.
