I am a fulltime freelance SEO. I work for clients all over the world and have never had to move one inch for my job. It is a mystery to me why your guy had to ‘come all the way from the north’. If he has access to your website, GA, GSC, and any other tools you use such as AHREFS or SEMRush, then he has all he needs.
Instead of asking loaded questions, he should be doing a site audit to establish a baseline and see what needs to be done, explain the results of the site audit clearly, then make changes accordingly and show progress on monthly reports.
I have never heard of Money Robot but at a quick glance, it looks like a spammy PBN links builder which WILL backfire badly. Google has been hitting unnatural links and PBNs for years now.
You are right to doubt this cowboy. Guys like him are what gives good SEOs a bad name.
