Cohen: "If you have subscription content, the user response to it will in effect tell the algorithm this isn’t not a relevant result, I’m not clicking on this. By making it free or by in essence saying it’s paid but Google treats it as free [because of First Click Free], there’s a significant advantage to them, because all their content is indexed, and I think at the end of the day probably helps the results. People are more likely to link to it and all the different ways it can be beneficial." - martinstabe
