@Marilyn26 this is the method to find listings and it works perfectly.
I had business cards made with my front thumbnail photo and the listing numbers and folks can take the card and always find me>>>>> or take a pic and find me, seems to work for repeat guests everytime.
Seems many hosts don't know where this number is located: on the listing photo page upper right corner : share will give a drop down and copy link is a good option.
Also, if you have named your property it will often come up on Google searches. good luck and happy hosting, Clara
