I have an online business making £xx,xxx a year. Ive been approached by an American company who sell the same product in America and are looking to expand into UK sales. My site ranks number 1 for all key terms and pretty much dominates the UK market for this product. They want the domain names, branding and website. I know what I would be willing to sell it for but what is the "going rate" when it comes to something like this... How many years multiples of profit would I be looking at? Lets also bare in mind that there could be a bit of tyre kicking going on here and I dont want to scare them off with a gigantic amount. Any help would be great!
