Why can’t you rank? I had no trouble getting ranked if I did the search console stuff and I had a unique name (which I checked before picking a name). Or do you just mean that your organic result is below the paid results?

What’s more likely, someone searching for your small business and some other cash rich business buying the ad space and stealing your customer.

Or a small business buying the keyword for a large competitor and stealing their business?

As a small business,I would prefer the world in which I can bid on my larger competitors key words than not be allowed. How many small web apps are basically wrappers with a better UX on top of standard AWS services?
