- Exchange links with sites that are related by topic. Exchanging links with unrelated sites is ineffective and unpopular.
- Before exchanging, make sure that your link will be published on a “good” page. This means that the page must have a reasonable PageRank (3-4 or higher is recommended), it must be available for indexing by search engines, the link must be direct, the total number of links on the page must not exceed 50, and so on.
- Do not create large link directories on your site. The idea of such a directory seems attractive because it gives you an opportunity to exchange links with many sites on various topics. You will have a topic category for each listed site. However, when trying to optimize your site you are looking for link quality rather than quantity and there are some potential pitfalls. No seo aware webmaster will publish a quality link to you if he receives a worthless link from your directory “link farm” in return. Generally, the PageRank of pages from such directories leaves a lot to be desired. In addition, search engines do not like these directories at all. There have even been cases where sites were banned for using such directories.
- Use a separate page on the site for link exchanges. It must have a reasonable PageRank and it must be indexed by search engines, etc. Do not publish more than 50 links on one page (otherwise search engines may fail to take some of the links into account). This will help you to find other seo aware partners for link exchanges.
- Search engines try to track mutual links. That is why you should, if possible, publish backlinks on a domain/site other than the one you are trying to promote. The best variant is when you promote the resource site1.com and publish backlinks on the resource site2.com.
- Exchange links with caution. Webmasters who are not quite honest will often remove your links from their resources after a while. Check your backlinks from time to time.
