this can be done but it who does it for you .
a lot off ppl can build somethink but the traffic is crap.
you need to build a website and promote it deeply in the niche your in, it take months and months but worth it.
a lot of ppl just throw advertising at the website from adwords , bing, facebook and others .
if you buy such website you looking at the monthly price it earns x24
example.
1k a month website will cost 24k to buy the website.
dont forget once you got the website it your promoting skills that make the traffic continue.(( not many websites survive heigh traffic without constant promotting))
no matter what happends your need to no market research and be a keyword research wizzard .
hope that helps
It never a case of just buying a heigh traffic website ,and it just sit there and continues giving a huge income, that all crap talk, all webites need constant promotting.
a lot of people hire im to do this for them or buy packages monthly to help them keep there website traffic continue
no work , no gain in profits or traffic as it all goes dead .....(( happens alot ))
