Advertisements are annoying to most of us when surfing the web. What is even more annoying is when loading the advertisement, our devices will sometime slowdown due to how resource-intensive the advertisement is. To solve this, the developers at Chrome have decided that they will soon block all resource-heavy advertisements from showing on the browser.
The developers combed through a lot of data that was collected from ads running on the Chrome browser, targeting those top 0.1% of ads that used the most amount of resources like CPU or network bandwidth. With this data, the developers of Chrome have decided to set a limit of 4MB of network data or 15 seconds of CPU usage in any 30 second period, or 60 seconds of total CPU usage.
If an advertisement crosses any of these thresholds, Chrome will block the ad and show an error page within the ad frame. Currently these thresholds will block only 0.3% of the total ads, but surprisingly just 0.3% percent of ads account for nearly 27% of network data used by ads and 28% of all ad CPU usage.
Chrome will slowly rollout these changes over the coming months to give ad creators enough time to modify their advertisements to stay within the thresholds. Users will start to see updates with the new changes in the stable Chrome app by August, 2020.
