Links are references from one webpage to another webpage. When clicked, a link will take you to the target URL in your browser. From a search engine point-of-view, links are like votes. When you get a link from a personal blog, it’s like a vote for whichever page the link points to. When you get a link from highly authoritative pages related to your industry, it’s like getting a superdelegate to vote for you. Each of the links we build is like superdelegate votes, each worth more than hundreds or thousands of less authoritative links.
