The home page is weird to me (and I have used cvent to find venues in the past): I select a city, and I have no other options. Venue size? Wedding hall or meeting room? No. None of these are options on the first page. Therefore, I don't expect much value from that site.

That being said, I assume you current problem is that no one knows about your site. Can you clarify what the value of your site is? It has to be more than a directory of venues. How does it help me? And who is yout target, businesses, conferences, weddings? Don't say all, unless you intend to serve all of them equally poorly.

Based on the style of the site, it has a modern template, unlike cvent. Maybe you are trying to displace Cvent just like AirBnb displaced vrbo: similar in features, but just so much better looking and "user friendly". If that's the case, it means your target demographics must be younger than the average Internet user. Does that match business admins who look for venues more than people getting married? You need to figure it out.
