Where I get lots of people finding me because of my website. Even if they find me elsewhere they have to go to my website to request an interview. I have a form (pre interview questions) everyone has to answer before I will grant an interview. One of the question is How did you hear about my daycare. the answers are: google (my website), facebook and on occasion daycarebear.
But it really depends on where you are located and how you promote your website. I have a facebook page as well and it helps me find clients as well.
I am also on google maps. Its not hard to get on the map.
