This is one thing which has to be kept in mind while building backlinks for your website. You should try to build unique links back to your site. All the successful internet marketers have followed this process of unique link building. What does this mean? This means that your backlinks should be unique . Your links should be from different websites. If you have created 20 backlinks but all are from the same website , then you will not be credited for 20 backlinks. On the other hand , if your 20 backlinks are from different websites , then it would pass a greater link juice to your website. Uniqueness is the most important thing. You must also pay attention towards providing informative content while building links. Further try to get links from domains which have a good name in the search engines and have been there from quite some time.
