The above mentioned statement "Ads are likely to be most contextually relevant to the sites on which they appear when using", is hardly accurate.
The answer for this questions, also depends on the sites visited by the person, i.e. the type of site.
In usual trend, the sites visited by people, do not show the relatable content. Mostly, adds pop us out of no where and they are unnecessary and have no relation to the context whatsoever, of the site which was currently being used. For instance, ads of shopping websites, and sometimes, ads for improper video games also tend to pop up.
