With billions of pages to index, rank, and return in appropriate handfuls to users, search engines like Google have a lot of tough work to deal with. That was true even in the early days of the Internet when the first search services had far fewer pages to assess and recommend. Since then, the size of the web has grown by orders of magnitude, such that today's search providers have responsibilities of an almost incomprehensible scale.Naturally enough, this means that the only realistic way to run a search engine is to rely heavily on automated assessments of page quality and the like. In fact, that has been the norm ever since the beginning, even if the particulars have changed. When Google first came online nearly twenty years ago, it unveiled a one-of-a-kind algorithm that had originated from some cutting-edge academic research. Since then, the link-oriented approach that characterized Google's PageRank system has come to be a virtually universal standard even though the original system is no longer updated. In my opinion, it's changed dramatically although rankings are still measured the same way. Basically, if Google gave away PR numbers or metrics then the entire system would come crashing down under the sheer volume of SEO providers.Even given that fact, though, plenty has changed, even beyond the greatly increased scale of the World Wide Web. Today's search engine algorithms go beyond link crawling to assess things like local directory presences, reviews on sites like Yelp, and social media mentions. Gathering all this information together, they form a digital idea as to just how interesting a company and its website are, and optimizing the results can prove to be a valuable undertaking for businesses in the area.Fortunately, Denver SEO services are ready to help with this work.
