Agreed.
If we are going to "pump" up the SEO factor, things like https://www.yourmechanic.com/book/#/addj=10021 for "Car is not starting" would not be in place.
Instead, maybe something like https://www.yourmechanic.com/fix/10021/car-is-not-starting
So yeah, I wouldn't necessarily hold this site up as heavily SEO optimized. Nothing against the company as they are a young company just not a good example IMO.
