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 that affects search results in significant ways.

The word “algorithm” refers to the logic-based, step-by-step procedure for solving a particular problem. In the case of a search engine, the problem is “how to find the most relevant webpages for this particular set of keywords (or search terms).” The algorithm is how Google finds, ranks, and returns the relevant results.
