In 2004, I started a small website on the side that had no business value at all. It was just a small community of video game fans (specifically Animal Crossing), and pretty quickly, the costs outgrew what I was willing to afford on my own.
So I opened up donations. Unfortunately that didn’t get me very far, so I eventually— and begrudgingly — added ads. I was very intentional about keeping them as unobtrusive as possible: just some banner ads at the top and bottom of each thread and forum, and a square next to the first unread comment. I hated pop-ups (the kind that opened in a new window — very common at that time), and I didn’t have them on any other page on the site (just forums).
This gained me about 10x the revenue I got from donations alone, and was able to scale the site’s hardware, allowing me to keep the site up and running for nearly 20 years, and provided some modest passive income for a time. (I just recently sold it to someone else, but it’s still up and running.)
My point is, that wouldn’t have been possible without ads.
I agree with most of you: sites today have a ridiculous number of ads and are very intrusive. But for sites that don’t go overboard, or for small independent YouTube channels, I don’t mind allowing the ads, because I know they probably wouldn’t make it otherwise.
Yes, I hear the comments saying “maybe they shouldn’t exist if they can’t monetize without ads”, but I’m not sure I agree. There are many that just wouldn’t survive with donations alone, and a subscription model may not make sense.
There are just some cases where ads make sense for them, and I’m ok with that (with the caveat they don’t go overboard), and because I’ve been on the other side, I don’t block ads.
