Jitsi is the best. Open source and free but all the dinosaurs use teams because it belongs to micro$oft. I installed it today because a client is using it and surprise: it works only with Google Chrome and Edge! No Firefox, no Brave.
Yes. I run ads for some clients on Google and Social media and they have amazing results. If you know what you are doing with targeted ads you can make a big difference.
What you refer to is called re-marketing to people who visited the website, engaged with ads, but did not buy. The problem is that there are lots of advertisers that do not exclude people who already bought their products and this is bad marketing because people getting bombarded with ads for products that will never re-purchase.
