How to target interests on Facebook (Instagram)?

Question

Facebook

Good night friends. I began to show interest in sports forecasting sites, as right there in the ads in Instagram Stories only these sites began to fall out - of this kind.
How to set it up? If a person visited such sites, then where can be configured to be shown to those people who visited competitors' sites (for example). ? Thank you very much
in advance .

Answer 1

In FB and Insta, targeted advertising is based on interests and retargeting, of course. You can't do it on competitors. Most likely, competitors have targeted sports and sports betting in their ads.
