It worked out as 40% ctr (+/- 2%) accurate based on the google figures (and that was for 2 different domains in completly different niches)
So therefore if we apply this to this domain = 40,500 / 100 * 40 = 16,200 CTR if the domain was in the number 1 spot on google.
16,200 x £1.09 if on ppc = £17,658 spent in one month
Domain name and seo work required to get it to number 1 = approx the same, except it will be there alot longer than 1 month
