The UI needs to be polished more imo. For example, the "Register" and "Click Here To Register Your Business" buttons in the registration modal have no vertical spacing, which doesn't look good. The site screams "Bootstrap/Material" or whatever to me, it doesn't have a unique branding or aesthetic to make it memorable or unique (of course it seems this is a WIP).
The "Claim Your Business" page doesn't seem too thought through... What if my business is in more than one of those categories? UI doesn't let me specify that. After clicking submit, I have to scroll to the bottom of the page to be able to tell that something happened (bad UX).
Overall, the website is very slow. Seems like the server is in Utah, and I've arrived here before the HN hug of death, so something else is going on. According to `whois` your provider is newfold.com? Haven't heard of them, so don't know what they're about so can't give advice there.
Lastly, performance and UI/UX aside, how are you going to handle the most difficult problem of all, verifying the authenticity of reviews? Even if this gets traction, if there isn't a good system to prevent fraudulent reviews then this site will be essentially worthless.
