…what?

If there were multiple search engines (there are) then SEO would focus on whichever were most popular

I’ve literally done work where SEO included making sure Bing was also optimized for, and I know others who have also done so

More engines would make SEO harder and longer as we assume each engine would search differently, but SEO will creep into any engine that gets popular for the obvious reason of people wanting their content seen

You don’t need it, but its a convenient website to let people save their info and support people financially across multiple professions all from one account

Many creators use PayPal or similar to let people just one-time pay through said creators site or app, but Patreon/Ko-Fi/etc. Allow a little more without needing to do all the work yourself

Nope, same thing, different words used

The idea is it’s more personable, instead of subbing to a Patreon or doing a one-time PayPal or what have you, you “buy them a coffee” or “buy them a pencil” or some other low-cost item that most people both understand helps people AND are cheap/something they might get themselves, so they’re more likely to donate

Also I’m p sure Ko-Fi has a better revenue split with those who use it than Patreon does
