This is why we believe in optimizing for users, not just search engines. Google algorithm updates According to Google: “With the amount of information available on the web, finding what you need would be nearly impossible without some help sorting through it. Google ranking systems are designed to do just that: sort through hundreds of billions of webpages in our Search index to find the most relevant, useful results in a fraction of a second, and present them in a way that helps you find what you’re looking for.” As mentioned earlier, algorithms are what comprises the ranking systems, and they look at hundreds of different factors.
Algorithm updates ensure that Google will deliver only the highest quality results to its users, and so we prioritize optimizing the factors that these algorithm updates tell us are the most relevant. Caffeine There were algorithm updates before Caffeine, but I want CY Lists to start with this. The Caffeine update finished rolling out in 2010 and was created to speed up the indexing process and provide 50% fresher results for searches. Since the web was growing at an enormous rate, from checking the entire web at one go to checking portions of it and updating their search index continuously. This is one of the main reasons why we focus on content freshness—to stay relevant to the users and the search engines.

Panda Google wants their search engine to give only relevant web pages to their users, and avoid content that is irrelevant or spammy. Unfortunately, there were sites that functioned as content farms—meaning they employed plenty of freelance writers that would churn out content to satisfy Google’s freshness requirements brought about by the previous update. So, Google released their Panda update to combat websites that had bad backlink profiles and spammy content, effectively ensuring that the surviving websites would be ones that actually created quality content.
