For example, if your assignment was finding psychology blogs, you'd be searching "depression blogs" and "mental illness" blogs, among everything else related to psychology. Once you find a suitable blog, you'll then collect the contact information.
The blogs you collect must meet a certain criteria and you'll be given training/instructions on how best to find everything off Google.
You'll be paid for every acceptable blog you collect and the rate will be determined depending on your commitment and performance.
