Do follow links have value so you should search do follow directory and bookmarking sites. Some social media sites also allow you to bookmark your site so I think it will be best to get a back link from them.

It is not possible to put a list here in the forum. Therefore, I suggest you to search it on net. You will surely get the desired results.

Use Blurpaliciouse for social bookmarking, it provides do follow.

These all lists are really helpful,
Thanks to all for sharing.

Login to www.web-directories.ws. You get not only bookmarking and directory list. There is press release list, article sites list, all based on niche and based on free and paid submission.

Hi,
I agreed, many sites allow only paid submissions on them but web-world is full of websites providing free submission.

Is directory submission is effective in SEO? If yes, please some dofollow and free directory submission sites.
