Google shows faster and lighter pages to people searching on slow mobile connections. To do this, we transcode (convert) web pages on the fly into a version optimized for slow networks, so that these pages load faster while saving data. These optimized pages preserve a majority of the relevant content and provide a link for users to view the original page. We call this technology "Web Light."Our experiments show that optimized pages load four times faster than the original page and use 80% fewer bytes. Because these pages load so much faster, we also saw a 50% increase in traffic to these pages.
Google displays ads on these transcoded pages so that publishers can continue to monetize their traffic. At the outset we support several 3rd party ad networks, including Sovrn, Zedo. We are interested in supporting ads from other networks as well. Read on if you run an ad network and want your ads to be supported on Web Light pages.
After the content has been optimized, we place the publisher's ads back into the Web Light page. We do this by detecting the existing ads on a publisher's page. If the original page was mobile-friendly, we can include the ad tags directly. If the original page was not mobile-friendly, we need to modify the ad tag's parameters to request a mobile ad from the appropriate ad network.
For more details, please see our FAQ.
If you're an ad network and interested in being included in Web Light pages, please contact us by filling out this form. We will need the following information:
- The format of your ad tags on a publisher's page
Providing us with examples of your ad tags or with a way to identify your ad tags in the HTML of a publisher's page.
- Parameters to request a mobile-friendly version of your ad
If the page that we're optimizing is not mobile-friendly, we may need to modify the ad tag. Please provide documentation on the ad tag parameters that would need to be modified so that your servers return a mobile-friendly ad format.
- Supported formats
We currently display ads only in the following formats: 320x50 and 300x250.
