Yahoo! advertising and cookie use

My Yahoo! gives personalised searches to their users by tracking what category they use most often. It does this by adding cookies to a cookie friendly computer.

The connection between searches and advertising

Unlike Google, Yahoo! is clearer on how they personalise marketing to their users. Search terms (i.e. the words/phrases a searcher uses, or has used in the past) are likely to give the highest weight for advertisements. This is followed by page views (i.e. what a searcher has actually viewed) and whether a user has clicked on an advertisement before (Yahoo 2012).

However, Yahoo! use cookies frequently to customise searches by tracking what categorises a searcher uses as they search (Cookie Central no date:online).

Yahoo’s policy suggests that if a Yahoo! searcher searches for “cars” a lot, and has viewed a lot of searches on the topic of cars, they will receive advertisements on cars. Due to the nature in which an inverted index is constructed, this also suggests that advertisements also stem on their inverted index. Specifically, advertisements that are tagged as “automobile” will show on searchers SERP who has only used the word “cars”.

Mazmanian (2012) suggests that free access search (namely, Google) allows users to be fed advertisements.

Does age matter to search engines?

Unlike other free access search engines, Yahoo! state that they do not use advertising for users who are under thirteen years of age.

I don’t have a Yahoo! account because I do not use their search engine; however, this suggests that a Yahoo! user must have a profile with the search engine. After all, how would Yahoo! know what age their searcher was?

Adults who use Yahoo! cannot opt-out of tailored advertising. Yahoo’s privacy policy does not stop an adult signing up for a new account, lying about their age, for example, in order to except them from advertising altogether.
