You can use it alone or with Postlets. If you already have a Postlet done for the home in question, you just provide vyoo.it with the direct link to that home and voila! Done & done.
One thing I really like about it is that if the visitor is on a smartphone, they are directed to the mobile optimized site. If they are on a desktop/laptop they get sent to the original Postlet.
So here's the question. How do you get the site out there in such a way that it's adding value & reaching your intended audience? Do you publicize the site in your print advertising? Or possibly include it as part of your signage on the home? Putting it on a flyer seems a little useless since, well, if they have a flyer, they already have all the info that you're trying to put out there into the collective conscious, now don't they?
And now here's my idea, tell me if I'm a crazed lunatic. I'm going to laminate a sheet that says "For more information about this home, direct to your smartphone, visit http://vyoo.it/kh4tu" along with a QR code that sends them to the vyoo.it site that I've created. That laminated sheet gets attached to the sign. Sort of a high tech alternative to the typical flyer in the box.
Creative use of technology or ridiculous attempt to be bleeding edge? You decide and let me know.
