Google developers unveiled recently an announcement in which they mention the imminent start of the blocking various types of ads in your Google Chrome browser, in the ad they mention those ad units that particularly it consumes a lot of traffic or loads the CPU.
In addition, they also mention ads that exceed certain thresholds, advertising iframes that consume too many resources will be automatically disabled and in addition to that in the coming months, experiments will be carried out on the selective activation of the blocker for some categories of users, after which a new opportunity will be offered to a wide audience at the end of August on a stable release of Chrome.
Advertising inserts will crash if more than 60 seconds of time is consumed processor total or 15 seconds in a 30 second interval on main stream or consequently if the ad consumes 50% of the resources for more than 30 seconds.
Ad blocking will also be activated when the ad block Ads upload more than 4MB of data over the network.
We recently found that a fraction of a percent of ads consume a disproportionate share of device resources, such as battery and network data, without the user knowing. These ads - such as those that mine cryptocurrency, are poorly programmed, or not optimized for network use - can drain battery life, saturate already strained networks, and cost money.
This move by Google is not new, since as we have previously shared here on the blog, Google developers have been working since last year to improve the performance and security of the browser. And it is that since the introduction of the new manifesto, the blocking, elimination and changes in the plugin policies, also the modification in the way in which the ads are displayed, are part of these changes.
According to Google statistics, advertising that meets the criteria specified lock it's only 0.30% of all ad units. In addition, these advertising inserts consume 28% of CPU resources and 27% of total ad volume traffic.
The proposed measures will save users from advertising with inefficient code implementation or deliberate parasitic activity. Such advertising creates a heavy load on the user's system, slows down the loading of main content, reduces battery life, and consumes traffic at limited mobile rates.
Of the typical examples of ad units to be blocked, ad inserts with cryptocurrency mining code, large uncompressed image processors, JavaScript video decoders, or scripts that intensively process timer events are mentioned.
After exceeding the limits, the problematic iframe will be replaced with an error page which informs the user that the ad unit has been removed due to excessive resource consumption. The blocking will only work if the user has not interacted with the ad unit until the limits are exceeded (for example, they did not click on it), which, taking into account the traffic restrictions, will allow to block the automatic playback of videos bulky in an ad without explicitly triggering user play.
For our users' resources as well as their data plans and to provide them with a good experience on the web, Chrome will limit the resources that a display ad can use before the user interacts with the ad. When an ad reaches its limit, the ad frame will navigate to an error page, informing the user that the ad has used too many resources. Here is an example of an ad that has been downloaded.
To exclude the use of blocking as a signal of attacks on third-party channels, which can be used to judge the power of the CPU, small random fluctuations will be added to the threshold values.
In Chrome 84, which is expected on July 14, it will be possible to activate the blocker through the "chrome: // flags / # enable-heavy-ad-intervention" setting.
