I'm a new user who is looking to use GSA SER . I contacted them and they advised that the software is only for Windows, I use MAC. Are there any alternatives for me? I am currently on Google PPC and would prefer to have organic traffic. I have in place seo plugin by yoast and am following all the rules yet traffic has not improved over 6-9 months. Reverting to the black hat. Any tips/advise appreciated.
