We are looking for a black-hat (or at least dark-gray) expert for a test we are running on a site we control. The domain is about a year old, in English, and hosted in the US. The single keyphrase has an SEOMOZ Keyword Difficulty score of 55%. At the end of the project a summary of methods used will be required. We'll be comparing techniques and results to white hat methods used on a sister site. The test will run for 30 days, but the results must stick for at least a year. Interested? Convince us of your worthiness.
