Here's what's happening right now
Somebody needs what you sell at 9:40 on a Tuesday night. They search for it. They land on your site.
There's a phone number on it. It's after hours. Nobody picks up. There's a contact form, maybe, and they're not going to fill it out.
They hit back and go to the next company on the list.
You never find out that happened. It doesn't show up anywhere. It just looks like a slow week.
