If you're using a Ylopo link to advertise on your own, you have full control over how many homes a site visitor can view before being asked to register on the site!
To create the link, just go to your home search website, which will begin with search. and perform a search for the homes you'd like to send or advertise. You'll see a very long URL in your web address bar, which you'll want to copy into another page.
You'll add the these parameters to the end of that URL to change when leads are asked to register: &lvl=X&pvl=X&hvl=X, where you'll replace X with a number.
Each parameter will limit a different type of click on the site:
pvl - photo view limit
hvl - total listing view limit, with unavoidable registration box
lvl - total listing view limit, with removable registration box
For example, if that number is 0 for all three parameters, a registration box will appear immediately, but if it is 100, the lead has 100 clicks on your site before we would ask them to register, usually more than a lead will need.
Finally, to make this long URL look nice and neat, we recommend a link shortener like tinyurl, bit.ly, or Goo.gl.
