If you spend time trying to promote your website than you probably know that all of the major search engines use links to your site to determine where you rank in the SERPs (Search Engine Result Pages) If your new to promoting websites this may seem a little confusing. Too illustrate this, view the internet like a popularity contest at your old high school.
Each link to your site is considered a vote. However not all votes are the same. If your a computer nerd, than a vote from other geeks will mean more than a vote from an airheaded cheerleader. Likewise if your a cheer leader a vote from a geek would not carry the same weight as a vote from the team captain.
What your running for and who votes for you make a difference. The Same applies with links. If your site is on travel and you get a link from a health website, it will not count the same as from another travel site.
Links are hard to come by but, one easy way is to leave comments on blogs. There are a few rules though. For your link to do you any good it needs to stay on the page. writing a short "Great Post" will likely not make it. Most webmasters delete these comments.
Blog comments take time, read the post, think about it and then reply with something that is relevant and useful to the original post. In most cases when you do this the blogmaster is happy to leave your comment on his blog, which includes a link to your site in the Name section.
Do not try to link to your site in the comment unless the link really adds benefit to the original post.
When looking for blogs to comment in, try to find ones that are on a similar subject as the site you are trying to get a link to.
Another problem is that not all blogs give links that are counted by the search engines. To find out more click on the link "DoFollow Blogs"
