Currently, Google is scanning emails in users' inboxes to collect information, thereby orienting the display of certain ads. For example, when Google sees you receive a lot of letters about shoes, you will receive promotions, discounts from Nordstrom for example.
Google will continue to display such ads in the future, just because they don't rely on user activity on Gmail but instead on Google Search, YouTube videos, applications you use or websites. that you visit. Users can remove these ads, not Google's crawl, by turning off the 'Ad Personalization' option in the Settings section of Google.
Scanning content in Google's Gmail has long been a controversial issue. Google's change comes amid concerns about collecting customer data and securing that data up.
In addition to this change, Google also advertised the G Suite product as the number of large companies using this service doubled last year with more than 3 million companies in use.
