If you ever want to see how endemic ads are to a platform the easiest way is to use the app and then the desktop version. I use Pinterest a lot when I'm bored/looking for inspiration for some stuff, and usually use the app without thinking very much. But I've been using the desktop version for a while - I've been sick as shit the last week and a half - and at first I thought there was some kind of glitch or just slow internet bullshit that made my page look empty. Just holes picked throughout the pins. I'm finally back at work and had a spare moment so I was on Pinterest and counted 9 ads/promoted pins out of 12 pins in a scroll.
That's an add for every 3 pins and four promoted pins which are ads under a different name. Like I'm fine with promoted shit, that's how some of the smaller websites and blogs gain a bit of traction. But look at the screenshots below, everything circled is an ad disguised as a promoted pin.
9 ads, 11 actual pins, but they're over shadowed by the ads that take up more space, and the Etsy ones are really deceptive, it's hard to figure out of the Etsy ads are personal ones from small businesses or if they're by Etsy, or worse their the ones by Etsy on behalf of small sellers that end up costing the small seller even more.
I don't have a point to this, other than that it's obnoxious.
