Which is the Field of work very Much Similar to SEO?

Guys, I am asking this just out of curiosity. Can you tell me which is the field of work which is very much similar to Search Engine Optimization, in which you have to generate Leads for the Company by Submitting Reports/Press Releases on Paid websites? There is a Monthly target for leads. I searched and found 2 Job Roles: 1. Market Research Analyst 2. Web Analyst But both of them are Irrelevant to the Job description I am looking for. Any information is appreciated. Thanks in Advance.
