Google Algorithm Updates Explained – Complete SEO Guide

Google processes billions of searches every day, and its goal is simple: deliver the most relevant, high-quality, and trustworthy results to users. To achieve this, Google regularly changes and improves its search algorithm through updates.

Some updates are small and unnoticed, while others significantly impact website rankings worldwide. In this article, we’ll clearly explain Google algorithm updates, their types, major updates so far, and how to protect your website from ranking drops.

These factors include content quality, backlinks, page speed, mobile usability, user experience, and more.
