Ask HN: Is it fair to judge a business based on web presence?

I have just started the journey of home ownership for the first time and as I look for services (such as inspectors, security consultants, etc) I am finding myself steering away from those who have have little to no web presence. Whether its the lack of website, or just the underwhelming nature of their presence, in my mind, any business taking itself seriously should be trying to have at least a basic informative website.
