Types of Link Building:
One Way Link Building - In one way link building, a website can link to another website but the other website will not be linking to the first website. Directories Submission, Blog Submission, Article Submission, Press Release Submission and Social Bookmarking are all the parts of one way link building.
Two Way Link Building - The two way link building is also known as reciprocal link building. This link building is done on the basis of mutual understanding between two potential link partners. In this method, one partner place a link on another partner's website and in turn the another partner will place a link on the first partner's website. This improves your website listing on search engine results.
