One way incoming links, are the best type of links to have for your site. They increase your PR and link popularity. They indicate to the search engines that your site is an authority on the keyword or keyword phrase used to link to you. However, incoming links are the most difficult to acquire. You can build your one way incoming links using the following strategies.

1. Build good quality websites or web pages with original, unique content. With great content, other webmasters will naturally refer visitors through links to your site.

2. Provide a free, useful service or tool on your site. For example, a link popularity check tool. This will bring repeat visitors and other webmasters will refer visitors to your site.

3. Give away something for free at your site. It could be a quality e-book, a useful program, software trial download, or a gift in exchange for links. You may give out the gifts after ascertaining that they have linked to your site. Some webmasters might bring down the links after collecting the gift, but many sites will still retain your links. Although you might not get many high PR sites linking to you, lots of low PR sites will still enhance your link popularity.

4. You can organize an award so that winners will link to you before claiming their prizes. Be sure to make your policy on this clear enough.

5. Pay to be listed in niche directories. Provide good topical articles on your site with links to your home page. Give permission to other webmasters to use at their sites.
