What is Google algorithm?
Google algorithms are sets of rules that Google uses to rank websites in search results. Google’s comprehensive system takes data from pages and tries to understand what searchers are looking for and ranks pages based on relevance and quality.
Google’s algorithms follow the same basic definition and algorithm rule that we described. Remember the last time you searched for something on Google. Whether you entered “cute cat videos” or “Hotels in California,” the search engine returned millions of results for you to choose from.
But how did it decide which results to show you and in what order?
Google has a very complex algorithm for providing search results and it changes quite often. And while the company doesn’t disclose the exact algorithm, the SEO Experts realize it by means of certain elements like the ranking factors and the experience they possess. Google claims to update its search algorithm several thousand times a year. In the vast majority of cases, Google’s algorithm updates are too small to notice. But every once in a while, Google introduces a change so fundamental that it disrupts the way we do SEO forever.
