I've only seen this type of thing with one other company. The idea seems practical. There was a $10K price to join and nothing smaller you could try out to see what you thought of the company. I had gigwork jobs years ago as a search engine evaluator. I was the one who would rank the landing page and decide how well it met the query intent. It was very involved. The ranking guidelines were 80 pages long. I don't know how they do it now in the age of AI, but they used to do it by paying people like me to go in and rank 'em. Right now I am taking a copywriting course. I'm a sr business analyst for my day job. This just caught my eye because like I said, there was another company that presented it to me over a year ago and it seemed plausible. You just have to really want to cold call.
