It is beyond hilarious that a company doing search engine evaluations asks in a forum where they should post their job offers rather than using a search engine to find the information...
First google result for "search engine evaluator scam" leads to a discussion of your company's practices, with mixed assessments.
Is it your company's policy to create multiple accounts on forums and post the same job offer multiple times? You just posted this job here under a different account less than a week ago.
