Google Top Heavy Update

The Google Top Heavy Update, also known as the Page Layout Algorithm, is a search algorithm update introduced in 2012 to penalize websites that display too many ads above the fold, the portion of a webpage visible before scrolling. The goal was to improve user experience by prioritizing sites with accessible content rather than ad-heavy layouts.

This update encouraged web designers and publishers to maintain a balance between advertising and valuable content, ensuring that users can find information immediately upon visiting a page.

Advanced

The Top Heavy Update evaluates page layout structure and the visual ratio between ads and content above the fold. Pages with excessive banner ads, pop-ups, or interstitials that obscure main content may experience ranking drops.

Advanced SEO optimization focuses on improving content visibility, page loading speed, and mobile-friendliness. The update is part of Google’s ongoing user experience efforts, aligning with Core Web Vitals and mobile-first indexing principles. Websites that use non-intrusive ad placements and responsive design typically perform better under these guidelines.
