Definition:
An interstitial is an ad that takes up the entire screen of a website and forces users to see the advertising before they can see the content on the page. It typically shows an image, video, or animation that promotes a product or service and encourages people to click on the ad to learn more.
Although interstitial ads can be quite effective in driving traffic to a website or product, many users find them intrusive and annoying. Therefore, interstitial ads may not be the best option for all marketing campaigns.

Thus, it ensured that such pages that used interstitials that block user content, would lose visibility in mobile search results. An announcement, which of course, does not affect all interstitials.
The interstitials that google allows are:
- Legal interstitials for cookies and age verification, etc.
- Logins for content that is not publicly indexable.
- Discrete banners that can be easily discarded and don’t take up too much space, such as app install banners in Safari and Chrome.
