Google’s algorithm updates are changes to the underlying code of the algorithm that changes how websites are ranked in search results. Most updates are small — thousands happen each year — but significant ones, like the Helpful Content Update or Core Updates, are named and can impact rankings across many industries. These updates often focus on content quality, user experience and authority signals. Working with SEO experts who stay current on algorithm updates is important, but if you have a strong, comprehensive strategy in place, most updates won’t hurt your rankings — and may even help them.
