A Brief History of Google Search Algorithms

Confused by algorithms? Who wouldn’t be, considering that Google changes its search algorithms hundreds of times each year. The point of these pesky formulas, however, is not as hard to grasp if you understand why they exist in the first place.
Google bases its search results on PageRank, its original algorithm dating back to the 1990s. PageRank was created to establish a hierarchy that would rank websites in search engine results according to importance and popularity. Generally, it does so by taking into account both the quantity and quality of links to a given page. Your website may not have received thousands of visitors, but if it’s the only online source of expert information on a given topic, it could still rank higher than a spammy page that has been viewed more times.
Many other factors determine the ranking of search results on Google. Take a look at the top three and what they mean for marketers:

Think companies are spending a lot on social media now? According to Duke University’s Fuqua School of Business, the social media spending of U.S. firms is expected to rise 150 percent over the next five years. If your reaction is that you couldn’t dedicate more hours to your activities on social networking sites without cloning yourself, take heart. Most marketers could strengthen their social media programs by making better use of tools and techniques already available to them.
Remember when purchasers paid marketers regardless of whether they were able to track and measure just how effective their campaigns were? How times have changed. With the introduction of each new measuring device, it seems, comes more pressure for marketers to whip up results. The fact that most Internet ad revenue in the U.S. is now comprised of performance-based advertising only highlights this fact.


Marketing is consistently becoming more personalized and targeted, focusing on smaller groups of relevant prospects instead of a single, large audience. Marketers need to focus on building closer, emotional connections with their customers to increase satisfaction, retention and revenue.
