Common Questions
How did you pick these companies?
We looked for companies that serve US small businesses and checked each one on its own website. We kept firms with a working site and a clear way to reach them. It is not a list of every company out there.
Do companies pay to be listed?
No. Nobody paid to be listed or ranked. We do not take placement fees.
Why are there no star ratings or reviews?
We have not tested these companies, so we do not rate them. Our roundups score only what we could check, and they say so.
Is T3CHS in the directory?
T3CHS sells hosting, domains and websites, and we do not list ourselves. Our sister company Clickflame is listed, with a disclosure on its page and anywhere it shows up.
A listing is wrong. How do I fix it?
Tell us through our contact form and we will check it again. We list the date each listing was checked.
