Pwede siguro kahit wala ng codes kung iisa or iilan lang ang platform kung saan sila nag-advertise. I'm pretty sure meron silang metrics na ginagamit, hindi pwedeng pakawala na lang sila ng pera without analyzing kung effective ba yung exposure campaign nila.
I don't think they will only focus here, its expected that a business with good marketing strategy will use different platforms to attract more gamblers.
People can also search in google and this will still display the website with the direct link unlike where there's a referral that its' included in the link before it direct to the actual site.
Yes, it's likely na meron silang ibang platforms na nag-advertise that's why sinama ko yung "iilan". In case na mas marami pa like google ads, malamang short campaigns lang din yun. I can think of other ways to measure kung ang case is walang codes or referral links. It won't be as accurate pero maka-come up din siguro ng maayos na analysis. Gaya ng nabanggit ko kanina, meron din paraan yung mga gambling sites
Napaghahalataan tuloy eh hehe
