who pays for their members for search the internet.
Have you ever used the google to search any thing.
this also same as it.
Instead they use ask.com search engine and pays for every searches.
It's completely free and earn as much as you can.
You don't need any special softwares to install or sign in with them every time to make searches. Instead use their search bar.
My recommendation is to get the firefox browser (it's free and fastest and only 5MB in size) and start search.
