Page layout algorithm (Top Heavy)

Also called: top heavy update, top heavy algorithm, page layout update

The page layout algorithm, nicknamed the Top Heavy update, is a Google ranking system launched in January 2012 that demotes pages burying their main content under too many ads above the fold. Sites with a normal amount of ads above the fold are not affected.

Google rolled out the first page layout update on January 19, 2012, and refreshed it at least twice more (October 2012 and February 2014). Google said the change affected “less than 1% of searches globally” and did not touch sites that place ads above the fold to a normal degree. The target was narrow: pages where a user clicks a result and has to scroll past a wall of ads before reaching the content they came for.

Recovery and where it stands in 2026

Because it ran as a periodic signal rather than a live one, recovery was not instant. You cleaned up the layout, then waited for Google to recrawl and for the algorithm to run again, which could take weeks. Google has not confirmed a standalone Top Heavy refresh since February 2014.

The principle did not disappear, though. The same “content first, ads second” logic now lives inside Google’s broader page experience signals and core ranking systems, alongside Core Web Vitals and the intrusive interstitial rules. Practical read: heavy above-the-fold ad density, sticky ad units, and a hero section that shoves real content below the fold still cost you, just through page experience and user behavior signals rather than one named penalty. The fix is the same as it was in 2012. Put the answer people searched for where they can see it without scrolling.

How it affects your traffic

If your pages underperform in classic rankings or get skipped by AI Overviews, aggressive above-the-fold ad placement or a bloated hero that pushes real content down is a common, quiet cause. This is rarely a one-line fix, because ad-density decisions, template layout, and Core Web Vitals are tangled together. Our SEO Consulting engagement audits your above-the-fold real estate, measures ad and interstitial density against visible content, and rebalances the layout so both users and Google reach your answer fast.
