If you want to easily get some quality backlinks to your site, the first thing you should do is leave comments on blogs that are relevant to your niche. You should be mainly trying to get inbound, or one way backlinks, as the major search engines all consider these to be the most important. Do a search for blogs in or similar to your niche and leave legitimate comments on them.
When you post a comment, you'll be able to post your link along with it. Don't abuse this method though because spamming the blogs with your links won't get you far. The point is to comment in a useful way so that you are contributing to the discussion. By leaving helpful comments you can also start to build relationships with other marketers in your niche, which can end up being just as useful to you as the links you get.
Here's a link building secret you won't see anywhere else - barter your professional know-how in exchange of backlinks. If have you niche skills such as SEO, web designing, writing logo creation, etc. then you are capable of making it big with the strategy. Once you identify your skill set, the next thing you need to do is directly approach a well-established site and give them an offer from your end. Share with them how you can help improve their site and all you ask for in return is a credit backlink on their page. This is a way to acquire superb branding, particularly if a site with a regular audience accepts your offer.
One more way to build high quality backlinks is called forum writing or forum signatures. There are many relevant forums that you'll be able to find online that give you the opportunity to post and have your link in the signature. Rankings will continue to increase with the use of forums highly reguarded by search engines. It's not really that hard to regularly post at forums, given that you're able to get so much out of them. Ensure that you are posting only to relevant forums to avoid negative rankings.
All in all, the advice we shared above can give your link-building venture a new push if you apply them. Just make sure that you don't indulge in any blackhat or unethical link building methods because that would ruin all your efforts.
