Building links to a site is the most critical factor if you are looking to rank highly in the search engines. A great place to get these links is from blogs. Links within blog posts have several advantages over other links types such as text-link ads.

• The links are often found quickly by the search engines because blogs tend to be indexed quickly.
• The links appear more ‘natural’ because they are embeded within text and don’t look like paid link.
• If the whole post is about your site, the links are in context and can naturally use keyword-rich anchor text.
• If the whole blog is about the same theme as your site, the link becomes even more powerful.
• Posts appear on the front page first, so your link is initially on the page which is viewed the most has the highest PageRank.
• Posts are often archived in categories, which means it will be on the same page as lots of related content and links.
• Finally, a post usually has it’s own page, where the links to your site will remain forever.

So where do you find blogs willing to review your site? One source is the brokerage sites that act as middlemen between bloggers and advertisers. Examples include reviewme.com and payperpost.com. You pay a premium for this service, but the blogs are usually of good quality and often provide traffic as well as link popularity.

Site review blogs and web master blogs are another good source. They are usually cheaper and some even allow you to write your own post. Good ones have a number of categories for posts, which keeps a post alongside relevant content once they are off the home page.  Crea-futur.com is one that has categories ranging from automobiles to mobile phones.

Probably the best, but most time consuming method is to search for relevant blogs and directly approach the blogger. It may be neccessary to be more flexible about your requirements, i.e. the number of links to your site, the anchor text used and deadlines, but it could be worth it for a very natural link back from a highly relevant site.
