WordPress.org

I've been using this about a year, and have been getting a pretty steady stream of leads. I switched from Diverse Solutions and have been very happy, I convert more traffic to leads with Displet, which is what's most important to me (why else would I have a website? I'm not really a blogger but I guess a pretty business card has some benefit). Completely indexable listings, so Google finds all my property addresses and I get a decent amount of traffic just from that. I like that they add new features pretty regularly.

I am certain the first 5 reviews are by friends or family of the owners of Displet. This one is a legit one, by someone who used it. I had to buy it just to see how it worked which cost me $100 "set up" fee, and $60 month first month. Then after it was "set up" I was then able to see it was NOT what anyone would want for many reasons. I sell Charleston SC real estate, and the properties it was showing were labeled NC just for starters. The popup widget caused problems in my site so I had to disable it. Within 4 days of realizing I didn't want it I notified them I didn't want it, and they wouldn't refund my money for being "unhappy with the product".
Their contract states if for any reason you are unhappy and want to discontinue service we will refund you your first month payment if you give notice within first 10 days which I did. Last I looked still haven't been refunded.

Here is more reasons why it isn't what you want:

1.) Uses an iframe which is not good for SEO, or user experience.
2.) You as the owner of the site has zero control over the functionality, design etc. because it's all on their server
3.) You have to give them backend access to your site basically in the form of an A record.

There is much better services out there, and the one I found is NOT only 100 times better, but also $20 month cheaper.

I've used Displet's IDX system for 2 years after they built a custom site for me. In short, it's awesome. They advised me to build out a number of niche landing pages and to drive traffic to those pages, which I did. I started out posting craigslist ads and got busy enough with leads that it made more sense to pay for traffic using Google Adwords. The niche pages convert extremely well. My website loads quickly, my customers like it, and I sell houses because of it. Other than referrals, it's my #1 source for business.

You have to host your IDX/RETS on "Displets" servers. Do a test and you see how slow the pages load, even with a fast internet connection. On mobile it does not load at all sometimes. Data from wrong regions show up in "your" area. No way to delete "powered by displet" advertisement. Can not use a standard Google sitemap plugin for your listings. You have no control over your data or content at all.
It is also not cheap.
