Video ads for small business: what to make first, where to run it and what it costs

make one short vertical video that shows your product or service in use within the first few seconds, run it on one platform with a small test budget, then make new versions of whatever works. You can film it on a phone, or make it with an AI ad tool, several of which have free plans with watermarked output. Showing the advert is a separate budget, paid to the platform you advertise on.
