Things have changed since 1998. Back then, link building was all about getting any link you could, from anybody, anywhere. Then SEOs started looking at related links, link quality, PageRank and so on. Each year, it seemed that the grip was tightening on the quality of links SEOs were trying to achieve, making link building more and more difficult.
It was always easy to get cheap and crappy links. However, it’s an entirely different matter to get a link from someone who understands the value of what they are providing. Today, link building is all but dead. At least, link building as we once knew it is dead.
Yes, links are valuable, and they likely always will be. But anyone offering “link building” as a service raises a red flag.
