Google algorithms are complex systems that are used to gain data from search indexes and provide the best results for a search. Over the past few years, Google has been making thousands of changes to its algorithm that strongly impact Search Engine Results Pages (SERPs). Every time Google makes an update, you need to check your web site pages to ensure they are conforming to the new rules Google has made. If you don’t, your site could lose ranking spots or be penalized for not meeting the new requirements.
