Do you know if any of those themes and/or plugins automatically generate pages for each listing in the market? We don't want something that requires manual upload. While that feature as a possibility for showcasing featured listings is a plus, the goal is to populate the website with listings and neighborhood pages. Everything I have seen uses iframes, dynamic URL's or different websites/subdomains to list the properties for sale.

The more research I do on the topic the more I am finding that subdomains aren't that bad of an option. A lot of the items you have linked to function the same way that the Wolfnet plugin that I am looking at using does.

Thank you for all your help.

I am currently working on a proposal for a clients Wordpress website development which includes ongoing SEO after the website is developed. I have looked into a number of options and the one that seems the most cost effective involves using subdomains for the individual listings pages.

What I want:

clientsdomain.com/listings/idxnumber/

What I can get for a decent price:

listings.clientsdomain.com/idxnumber/

So the majority of the website will actually exist on a subdomain because the IDX API will automatically populate pages for all of the MLS listings in the area (hundreds or thousands). Meanwhile the domain itself will have all the neighborhood pages and other optimized content, blogs and whatnot. My concern is that dividing the website like this will have negative effects on SEO. There wont be duplicate content across subdomain and main domain, but they will share a lot of links back and forth. I haven't found any recent sources on the topic. Almost everything I have found says that dividing a website in this manor is bad for SEO, but these articles are often many years old.

1. Does anyone know of a Wordpress plugin/IDX company that can provide a solution that doesn't use a subdomain and actually just lists each MLS page within a directory? I am open to using another platform, I am just most familiar with Wordpress.
2. Will using a subdomain in the ways mentioned above have a profound negative effect on SEO?

Thank you for your time in responding, I greatly appreciate it.
