Back linking is just linking other pages to your site. For example, let say you have a sales site that has lots of products on it. Like a big store like Wal-Mart. The search engine like to have small amount of specific key words instead of hundreds of keywords on a web page. If someone has a Wal-Mart site or a similar one: I would highly suggest that they make many different site focusing on specify items that they want to promote on line using hyperlinks to there main website on the specific wal-mart site. As you make each site put a link to the other site that you made on the new site as a back link. The way I look at it is there is no difference in creating lots of different websites and back linking them, or have a brick and portal company place ads in 100 different newspapers across the country in order to find new customers. Many companies does that for example car markers and dealers does that all the time. Russ Falls
