Google algorithm updates refer to changes made to the complex mathematical formulas that determine how Google ranks websites in its search results. These updates are designed to improve the quality and relevance of the search results for users by taking into account changes in user behavior, technological advancements, and other factors.
The effects of Google algorithm updates on a website can be positive or negative, depending on how well the website aligns with the changes. For example, if the update rewards websites that have high-quality, original content and penalizes those that use spammy tactics to manipulate rankings, websites with quality content will see an improvement in their rankings, while those using spammy tactics may see a drop in their rankings.
