What are Google Algorithm Updates?

Each year, Google changes its search algorithm around 500–600 times. While most of these changes are minor, Google occasionally rolls out a “major” algorithmic update (such as Google Panda and Google Penguin) that affects search results in significant ways. Marketers and SEO experts need to be aware of these in order to see the effect on their websites and that of their clients.
