I find that my FB feed is roughly 50% ads. Sometimes there are two, or even three ads in a row. I barely use it anymore (and I've literally never clicked on an ad). I wonder why FB thinks people will use their product when it is half advertisements. People watch 21 mins of TV with 9 mins of commercials, and they would revolt if it were 15/15.
Its not that I don't believe your general point but I would be interested in evidence that you're getting more than 1 in a row. I am $50MM+/year spender on Meta ads and while I know that ad load is up I don't think its up that much where ads run alongside each other. If you can show me evidence of this I will make a big fucking deal of this to Meta.
I typically bail when I see two in a row, in a vain attempt to send the message that multiple ads back-to-back is not cool.
edit: just logged in and of the first 20 timeline items, 9 were ads (including two cases of back-to-back ads). It's basically half of what I see.
