What kind of software, membership site or service do internet marketers require the most? Is it backlinking, is it simply learning a "make money method" via interactive course? Is it SEO checker? Is it site builder? The reason why I am asking is because I have have agreed with a highly experienced programmer that we could start a new project offering a software/service for internet marketers. I'm doing market research now and wanted to know what you guys think. What kind of service would you pay for?
