I know off topic, but my ads always seem geared to something I've searched on google. I have an ad for a clothing store, round up, NEJM, masks and Dreams unlimited.
I can't figure them out sometimes! I was getting the Disney mask ones (which I attributed to matching site content) and some for scrapbook paper storage (which I actually searched last week) but then I just had a clothing one for something I have not recently purchased and that doesn't relate to the site. I didn't get the political ones, though.
I think it must be a mix of targeted and "bundled" or something.
