Yahoo! Search Marketing offers advertisers tools that allow them to better understand the performance of their online marketing campaigns. To use these tools, an advertiser adds Yahoo! Search Marketing Tools web beacons to their web sites. These web beacons are electronic files served by perf.overture.com that enable us to collect anonymous information from visitors to the advertiser's sites via cookies. These web beacons collect only anonymous non-personally identifiable information and the URL of the web page where the web beacon is located. We maintain data separately for each advertiser.
The data collected are used to create aggregate reports for our advertising clients. No individual level data is shared by Yahoo! Search Marketing with the advertiser and no such data is shared between different advertisers. For example, we can report to an advertiser that X% of the visitors to its web site had previously viewed an advertisement to its site, and that Y% of those visitors also successfully completed a registration or purchase process later during that same visit.
Except as noted in this privacy statement, information collected from online forms on advertiser web sites is not shared or passed to Yahoo! Search Marketing by our advertisers. Each advertiser is responsible for the privacy practices of its own web sites and we encourage you to read those policies to understand how each advertiser collects and uses information on its sites.Opt-out
If you choose, you may opt-out from Yahoo! Search Marketing using information collected with web beacons and cookies outside of the Yahoo! network of web sites. Cookies will need to be enabled for the opt-out to function.
Note: This opt-out applies to a specific browser rather than a specific user. Therefore you will need to opt-out separately from each computer or browser that you use. Additionally, the opt-out only applies to cookies used by perf.overture.com and not all cookies set by overture.com.
