Webprojects.ru summed up the results
of the optimization market research . Brief information about the study is published on their website, detailed results of the study are sent to participants in the form of pdf to e-mail (40 pages - ouch!). In a complete closed report, the client side is well covered, for example, loyalty level, job evaluation criteria, ways to attract customers.
Useful results from the study:
- the optimization market in Russia is estimated at 70 million dollars, 50 of which settle in the pockets of optimizers.
Most optimizers do not last long in the market.

I wonder - why is it not optimizers who work 1 year on the market? ;)

And of course, all optimizers workaholics. It is easy for me to believe this, I myself sometimes sit until 24-00 in the office and analyze competitors.

The rest of the results I propose to look at the WebProjects website at the link above. The closed report does not contain any restrictions on distribution to third parties, so if the survey organizers have no objections, I would attach the document to the topic after some time (otherwise, the motivation to participate in the next survey will decrease).
