Paid To Search ( PTS ) is a model of Single Fighter Action ( SFA ). There is similarity with Paid Per Search ( PPSe ), which is need someone to search in the searching box that is provided by the website.
The difference is : In PPSe, We get paid when We provide our site with the searching box and the visitors search on the searching box. In PTS, We get paid when We DO the search on the searching box that is provided by the website ( which is not our website ).
So, the conclusion is : PPSe is a passive way to get paid for search & PTS is an active way to get paid for search. PPSe need a website or blog, PTS doesn`t need it. U can choose what U think the most suitable for U. If U have website, I recommend U to choose PPSe. If U don`t, just pick PTS cause U don`t have any choice.
The paidpersearch.com is a fine example of that
