# Page layout algorithm (2012): what it changed and what it means now

## The short answer

Google launched its page layout algorithm on 19 January 2012 to demote pages with little content above the fold or too many ads at the top. Google said it noticeably affected less than 1% of searches globally. Search Engine Land nicknamed it the Top Heavy update; page layout algorithm is Google's name.

## Key takeaways

- Google launched the page layout algorithm on 19 January 2012, per its Webmaster Central post.
- It targeted pages with little visible content above the fold or excessive ads at the top.
- Google said it noticeably affected less than 1% of searches globally.
- Top Heavy is the nickname Search Engine Land and others gave it, not Google's name.
- Google's page experience guidance still asks whether ads distract from or interfere with main content.

## What Google changed

On 19 January 2012, Google announced "an algorithmic change that looks at the layout of a webpage
and the amount of content you see on the page once you click on a result," in a
[Webmaster Central post](https://developers.google.com/search/blog/2012/01/page-layout-algorithm-improvement)
by Matt Cutts. Pages whose first screen "doesn't have a lot of visible content above-the-fold or
dedicates a large fraction of the site's initial screen real estate to ads" could rank lower.

Google drew a line: the change "does not affect sites who place ads above-the-fold to a normal
degree." Page layout algorithm is Google's name. Top Heavy is the industry's nickname: Search
Engine Land wrote that "we and others have taken to calling it by the more descriptive 'Top
Heavy' name."

## When it rolled out

Google's post said "today we're launching" the change, on 19 January 2012. Google stated no
completion date. Search Engine Land reported a refresh of the algorithm in October 2012, which it
called Top Heavy 2.

## What is known about its impact

Google's figure: "This algorithmic change noticeably affects less than 1% of searches globally."
Google explained that meant in less than one in 100 searches, a typical user might notice a
reordering of results.

## What site owners should do

Google's ranking systems guide does not list a page layout system by name. The principle sits in
its page experience guidance, which says Google's core ranking systems look to reward content
that provides a good page experience, and asks: "Does your content avoid using an excessive
amount of ads that distract from or interfere with the main content?"

- Check the first screen of key templates on common desktop and mobile sizes: the main content
  should be visible without scrolling past ads.
- Make sure visitors can easily tell the main content apart from ads and other page elements.
- After changing a layout, expect a delay: Google said on a typical site it can take several
  weeks to recrawl and process enough pages to reflect it.

## How to check whether it affected you

This is historical. Search Console keeps 16 months of data, so January 2012 can only be checked
in archived analytics, by comparing Google organic traffic to ad-heavy templates before and after
19 January 2012. The [Google Algorithm Updates timeline](/updates) lists every update with its dates.

## Later refreshes

- **Page layout 2, or Top Heavy 2** (9 October 2012): Matt Cutts called it minor, with "~0.7% of English queries noticeably affected."
- **Page layout 3, or Top Heavy 3** (around 6 February 2014): Matt Cutts said a refresh became visible on "~Feb. 6th" and gave no impact figure.

## Related updates

- The [Panda update](/updates/panda-update-2011) was the previous site-quality change, in 2011.
- The [Intrusive interstitials update](/updates/intrusive-interstitials-update-2017) extended the idea to mobile pop-ups in 2017.

## Frequently asked questions

### What did the page layout algorithm target?

Pages where the first screen a visitor sees has little visible content or gives a large share of space to ads. Google said sites placing ads above the fold to a normal degree were not affected.

### Why is it called Top Heavy?

Top Heavy is an industry nickname. Search Engine Land wrote that while Google called it the page layout algorithm, it and others used the more descriptive Top Heavy name because it targets pages top heavy with ads.

### How long did recovery take after fixing a layout?

Google said the algorithm reflects changes as it recrawls and processes enough pages from a site, which on a typical website can take several weeks.

### Does the page layout algorithm still apply?

Google's ranking systems guide does not list it by name, but its page experience guidance still asks whether content avoids an excessive amount of ads that distract from or interfere with the main content.
