5 ways I'm apply to build quality links

I often wonder about how sich build quality links to my blog so they can get good rankings in search engines and get lots of traffic / visitors. Build quality links is a great way to increase the PR that we have backlinks on other sites that also get ranked on search engines.

What must be remembered in building Links is any site related to our blog and the quality of the site itself, or in other words "Quality over Quantity", here are some methods that I try to apply on how to build quality links to increase popularity our blog:

Social Bookmarking

Social Bookmarking is one of the most common ways used to easily and quickly build backlinks to your blog. There are many Social Bookmarking sites to choose from, your job must choose wisely and do not use all to save time, you must select a dofollow. Social Bookmarking is not the only option, you can also join the forum and post a link to your blog on the profile to get backlinks from sites with high PR. You can also use the social community that allows you to create a blog for free and build some backlinks to your main blog.

Forum

To comment on a forum is another way to build backlinks to your blog via the "signature" you. Some forums do not allow "signature" so choose your forum that allows you to add a "signature" so that you can put a link to your site there. Some of the best forums that I know is DigitalPoint, SitePoint, and there are many other forums that you can choose. Some doubted this method and thought do not have much value but I've noticed, many websites were ranked high because of gaining a lot of quality backlinks via the forum.

Blog commenting

Although many do not use this method because it would prefer to join with social bookmarking and forums, but blog commenting is also a good way to build links with quality, especially if you are commenting on a site with high PR. You can also get a link from a site that offers the "Top commentator" on their site. Be careful when making comments, you must ensure that your comments valuable and relevant to the topic that you commented it so you do not assessed spammed.

Being a Guest Contributors

There are many sites that receive posts from visitors, as long as you have a good article. You can select some sites that you like and write about them, then you can leave the links at the end of the article. You can do a good communication in advance with the owner of the site so that when you offer yourself as a contributor to their guest will receive with open arms. Try to send official e-mail so you will have a greater chance of being accepted.

Article Marketing

Submitting articles to the site Marketing article directories is one way to build quality links, but you must be careful when sending the same article to many article directories because Google will consider your articles as duplicate content. Choose the best article directories so you do not need to submit to many article directories.

That's 5 ways I'm apply to build quality links. Do you have any other way? If there is, sharing in the comments yes ... In order for me and my other colleagues to "science" is good.
