All you're measuring is hype though. Startups that rely on likes, follows, etc. as a gauge of success/traction are by nature, hype driven.
There are many industries - B2B, EdTech, etc. - where lack of social media traction is not at all an indicator of the health of a startup. I know because I run one. We have 0 likes, 0 mentions, 0 follows, but a hundred paying customers and on track to hit 1MM in revenue in less than 20 months since launch (with only 4 employees).
I hate to be critical of other founders, but all you're doing is contributing to and validating all the silliness that is the SV startup scene.
