One very effective link building trick is to simply comment on blogs that are in 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. To start off, you can simply search for relevant blogs that are related to your niche and post a quality comment on it.
Don't forget to put in your link when you post to a blog. Don't abuse this method though because spamming the blogs with your links won't get you far. The best way to leverage the blog commenting method is to be productive and add value to the blog in the best possible way. Ideally, you will be meeting other marketers as well as building backlinks, and this can also be very good for you.
Here's a link building secret you won't see anywhere else - barter your professional know-how in exchange of backlinks. If you have unique skills such as SEO, web designing, writing, log creation, etc. then you have the skills to become big from the approach. 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. Discuss with them how you can help them get more out of their site and all you ask for in return is a credit backlink on their page. This is a way to literally pave your way to quality branding, most definitely if a site that already has a decent audience takes you up on your offer.
You can also use press releases to gain quality backlinks to your site. You can send out a press release about the launch of a product or website, and this can get distributed to many different sites. Press releases are great for backlinks because the search engines consider such links very relevant as well as unique. On top of this, you don't even have to pay for these backlinks.
PRWeb and PRLeap are among the press release distribution services you can use. Include your website or product's USP in your press release before you send it out for distribution. Do this so that the press release can get wider distribution, and you'll be adding to the total backlinks you can get. Putting in the effort is worth it when building quality backlinks. The above tips are easy but some still find them difficult to follow. Persistence is the key to successful link building, don't give up.
