This kind of web site link building arose as a result of the need to build link popularity fast after recognizing that search engines love links. This is, basically, two or more sites exchanging links with one another. Site A link to site B and site B link to site A. Because of this, there arose many link exchange sites on the web. Where webmasters can either register for free, for a small monthly fee or a one time fee and exchange links with other webmasters automatically instead of manually. Doing link exchanges manually takes time hence the need for these link exchange sites.

When doing reciprocal linking as a web site link building strategy, use your keywords in the anchor text properly. The anchor text is the text in the link that point to your site. Use different keywords for your link building. Search engines have realized that webmasters use link popularity to artificially gain top positions in search rankings. So the value of these reciprocal links are being greatly discounted. That is, given less and less value. And one way they detect reciprocal links is if you have hundreds of these links with the same keywords in the text as anchor text. So vary your anchor text links using different keywords.

The advantage in writing articles is that it gives a more natural incoming link to your site . Better than ordinary link exchange where your text link is placed in a link directory. Another point to take note of when doing reciprocal link exchange is making sure your link is placed in a page that is one click away from your link partner's home page. By doing this your link is spidered faster by the search engines and some of the home page Page Rank (PR) is reflected on to your link. This ensures that the link appears faster in your backlinks. 15 SEO Web Directories for you to submit your link.
