Hi Noah - See some examples below. The plugin seamlessly embeds on any site (no iframes or subdomains). You will see indexable pages when using the WordPress plugin OR when using our optional PHP class. Our main demo site is https://charliesmithrealty.com - and a live client site using WordPress would be (las vegas) https://www.newdoorresidential.com/.
Let me know if you have further questons!
Do you have any productoin sites making use of your plugin that you can share?
I am curious as to the indexabilty of the listings, URL structure and general responsive speed. I know that last one comes with some technical consideration.
