Hello, what is the best case for paying someone via paypal for seo? Should he send an invoice with details or is it ok, if I choose option of paying for services and then add our agreement in to notes? My concern is that, I have agreed on some terms with freelancer on facebook, I have the whole conversation screenshoted and I asked him to verify my terms and I have listed them. I am asking, because in past I have been scammed or instead of increasing my ranking, my site got deranked. So now I want to be protected, if something goes south, I would like to get refund via paypal. Thanks for advice in advance. Any other tips what to do? Edit: does here also apply, that my "buyer protection" is 180 days long?
