Google expands Gmail advertising system
In the future, Gmail users should expect that Google will no longer necessarily tailor contextual ads only to the message currently open, but may also tailor them to older emails at times.
According to Heise online, the company has announced this in a blog post. The reason given in the post is that for some messages, such as birthday wishes, there are no "good" ads that Google can display. In such cases, other messages will be used in future. Google does not store any additional information for the new feature. The allocation of advertisements is completely automatic; no employees are involved in the selection of advertisements, neither messages nor other personal information are made available to advertisers.
