Earlier quoted context omitted.
But the playing field is not level. You will compete for ad space against big corps that can easily spend millions on advertising and can do much better targeting than yourself.
>can do much better targeting than yourself. All existing online ad platforms provide very good targeting tools and do automated optimizations on your behalf. On a targeted audience you can easily outcompete big corps with a generic offering as it's not overall budget that matters but how much you're spending per view/click/conversion adjusted for how relevant your ad is.
But whenever they actually study these things, from all I've seen, the benefits of targeted-to-the-individual advertising fail to materialize.
Targeting by the content of the site can work (eg, advertising cake decorating tools on a blog about cake decorating), but at least the vast, vast majority of all the privacy-invading, personal-data-aggregating "targeted" advertising online seems to do no better than the much simpler forms, and as I understand it, in many cases it does worse.
