You always see high conversion rates for new ad mediums, and those rates reduce over time as marketers abuse consumer's attention.

One of my favorite examples is Amazon reviews. Once you a time, those were legit and you'd see consumers referencing online reviews for products even if buying the product in a store physically, because it was valuable content.

Now, the reviews are so untrustworthy there are multiple sites that automate going through them to flag BS.

The unfortunate thing is that even after an ad medium becomes ignored by the majority of an audience, there's still an audience that's one to two standard deviations below the norm in suggestability that get preyed upon by advertisers. So it's those people that are the 0.1% clicking on general banner ads and purchasing a product. These are the same people that "call now" for those late night TV marketing commercials.

So the cycle for any ad medium is to get the attention of an audience, abuse it until most people stop paying attention, and then prey on the suggestably handicapped. It's a shitty industry, and quite unfortunate as if everyone could agree to not be awful, the fundamental feedback loop is one intrinsically motivated (find out about crap I'm highly likely to enjoy). But we're talking about a class of organizations (corporations) that can't even self regulate when lives and health are on the line, so that's certainly not going to happen for ads.
