How to Build Free Backlinks for Your Site or BLOG

How to Build Free Backlinks for your Site (backlinks are links from other sites that can help increase your site's popularity).
Although paid methods can help you get backlinks a lot faster, using these free methods can save you a lot of money.
Directory Submission. There are literally thousands of free web directories out there. This is one good way to build backlinks, although directory submission takes weeks to months to years to get approved because these are manually approved. Please make sure the directories have a Google PageRank value.
Article Submission. To do this, first you need to have an article ready. Your article must be unique, well thought of, and related to the site link you want to place on Articles Directories. Articles on Article Directories are then copied to other sites along with your link, that means it helps in getting more backlinks for your site.
Comment Posting. Akismet was created to prevent people from spamming blogs. To prevent your site from being banned, make your comments relevant and sensible and don't place a link on your comment, but only on the URL field. Make sure these comments doesn't have a nofollow on the link rel attribute.
Write Quality Content. Quality content means original and interesting content that people will talk about and possibly post links from their site, talking about the post you made on your site. It is best that your content is current and the topics are widely talked about, even controversial topics are good link bait. Social Bookmaking. Got a good content that nobody knows? Share it with everybody. Social Bookmaking sites help increase your site visits and backlinks when people bookmark your site on their favorites list. Just make sure you don't abuse by bookmaking all the pages of your site or you will be banned by them.
Give something away for Free. Do you know how to create web templates? Build as many as you can and people will start using them, and along with it are your links. The number of backlinks generated are endless. But if you cant, you can still give away something for like free quote-of-the-day, etc. something like that.

Social Networking. MySpace, Friendster, FaceBook, and even YouTube can be called a Social Networking site. These sites are good sources of traffic, especially if you a lot of friends in the list or you have a funny and interesting content you have posted on your account page.

Government and Education Sites. Government and Education sites are quality backlinks, meaning Search Engines value sites more if they are linked from these kind of sites. It's very hard to get these kind of links but you can start by participating in their forums.

This way you can enjoy posting on forums and you will be surprised you already have thousands of posts on forums with your links on your signature.
J oin Groups. Being an active member of several organizations can help you get backlinks as well. Most established organizations have good traffic and PR and if your site is linked there, your site can have a good backlink from this site as well as other members can link your site from their sites too.
