I have heard that social bookmarking sites are a great source of backlinks. I was bookmarked my site into some different social bookmarking sites but I've not got any back links. So, what I heard is it FALSE!?
Not at all, they just helps us spread awareness about newly published items and help us bring live traffic. It may also help us to get indexed our urls faster in search engines but in terms of backlinks, forget about social media.
please check on the sites which you are using... it may be nofollow which might block your link building...
Not all bookmarking show their links as backlinks. But that doesn't mean that the links are not there. They are there to spread our word aroung the web so that we show our site in the SERPs.
Many of the bookmarking sites are no follow, but for the ones that are do follow they do give you links. As basickno said they do help you get your site cached faster. It is a good method to put some time into but there are better methods to get links
They can and do provide backlinks, and should be a part of your link building strategy. But don't rely on them entirely, mix them up with other sorts of links. The more diversity, the better.
You will get links from dofollow social bookmarking sites. Its actually help us to get indexed the site faster in search engine.
for me, i have never really benefited from social bookmarks when it comes to links, just for awareness and getting indexed faster. but they still might bring some traffic
