Sure, we did keyword research, we recommended partnerships and widgets and architecture advice, but we didn’t step back and take a good look at our target audiences, what sites were meeting their specific needs in search results, and what we specifically could build into the product that would be far more desirable than what everyone else had (not even thought of yet ideally) to make sure our entire site is superior, resulting in the inevitable stealing of search traffic from our competitors.
In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links. PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.
The strength of your link profile isn’t solely determined by how many sites link back to you – it can also be affected by your internal linking structure. When creating and publishing content, be sure to keep an eye out for opportunities for internal links. This not only helps with SEO, but also results in a better, more useful experience for the user – the cornerstone of increasing traffic to your website.
Website owners recognized the value of a high ranking and visibility in search engine results, creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term. On May 2, 2007, Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona that SEO is a "process" involving manipulation of keywords and not a "marketing service."
