If somebody makes new classifieds website as example buying and selling houses , people should register in the website with details of their house which are going to be on sale . If those people who visit the website dont want to sell houses , they wont enter details . That means website doesnt get any data or 0 houses for sale or 1 or 2 houses for sales .
1) how to get more houses added on the website which are going to be on sale
2) there are similar websites which are giving data of houses for sale . can we add those houses on this website , by mentioning that this house details provided by ....website . is it permissible to do ?
(i hope now understands)
