Welcome to the Q&A Forum

Hi Kamishah, On regard your question, is domain redirection a good method for SEO? No, it is not. Said that, if the mistake was already done: you should study the DA and the spam score of the xyz site before thinking on setting a 301 domain redirect. Considering that the xyz site has a low spam score and a good DA, at least equal to the solutionfall.com you might go ahead. Perhaps you consider, from now on, to get true organic backlinks by having unique high quality content instead of "comment backlink". Good luck! Mª Verónica
