I realize it's not ideal SEO wise, but it's the best option in this case.

My SEO skills are definitely not the best and while I use Instagram, too, I've found it hard to get people to actually engage.

SEO targeting keywords such as "homes for sale in [location]."

Primarily, search engines are designed to favor websites that match closely with the searched keywords (SEO) or those who can pay hefty fees for advertisement.

The exception would be a superior website maintained for SEO, IF your investment program is large enough to cover the $5k upfront cost and the $500 per month maintenance for an optimized website. 

Can you try some seo in the listing title or description? 

If that happens, you need to have the other one ready to go.The SEO factors include frequency of bookings so you will end up being mostly booked on one or the other.

In addition to looking at their reviews, see who wins the SEO war if there are multiple PMs with direct booking sites.Google the lake name + cabin or rental house and see who pops to the top.One other question I like is "What makes you different?"

You can drive for dollars, go after pre-foreclosures, distressed sellers, PPC, organic search SEO, MLS expired, FSBO's, r.e. agent network, estate and probate, on and on and on. 

I am working on a product that will help small-medium size landlords launch and maintain Internet presence at a small monthly cost without spending big budget on custom development.It will include: SEO, custom domain, direct syncing with your property management software, syncing with QB.
