Typically I sell expired domains with Pagerank. I then add a site onto that domain and build legitimate traffic to increase the alexarank People that buy on Flippa for some reason seem to love the following: 1. Age 2. Pagerank 3. AlexaRank So like I would optimise a webpage for maximum conversion rate I optimise my sites and flippa listings for maximum conversion rate. So just a few days ago I sold a site on Flippa and it sold for $500. People just assume that they can add adsense and the site is going to make loads of money, but when the traffic isn't search engine traffic they get upset. My listing clearly states that I buy Pagerank domains and sell them on and it also clearly states that it was an 11 year old domain. The problem is that where I state its an 11 year old domain I had also selected on the right hand side of the listing that the site established date was 11 years old when really it should have been established for 6 months. I made a mistake and I know now not to match the domain age with the site established date. The site and domain has been transferred and he also gave me positive feedback. He has added adsense banners all over the site and as I already know the adsense profit is minimal. The guy can't think of any other ways to monetize the site so he has decided to ask me for a refund saying that the site isn't actually 11 years old. I do not want to give him a refund because I have spent my time transferring it for him and paid flippa fees. If being an 11 years old site was so important to him the he should have done his due diligence properly but I am wondering if he has any chance of getting his money back for this? Any advice is appreciated.
