Hi, Purchasing traffic for your business is a good idea ...but you can also have a SEO service to increase traffic for your site...
i think you can easily get traffic through seo service.because blog commenting,forums posting,social bookmarking are the easy ways to get nice traffic for your website.
Are you referring to SEM when you say "buying traffic"? If yes, then SEM is great option for any business. You just have to very wise and proactive when indulging yourself in it.
Buying traffic is good, but on page and off page optimization both can gives you quality/more traffic.
Buying trafic can give you good amount of visitors but it is not guaranteed to get targeted traffic for your business. It would be better to spend money in Google Adwords and PPC than to spend in buying traffic. It may give you a better business
I would say it really depend of the kind of traffic you are buying, cheap untargeted pop-under traffic won't do much for you, sure it will lower your alexa but not more. But if you buy quality targeted traffic it could really improve your earning
I still haven't found paid traffic that converts. The paid traffic is usually from pop-ups on other sites, and such pop-ups is usually clicked away without being looked at.
I started a free trial at revisitors.com and they promised me 10,000 free "targeted" hits but so far I have only gotten a few hundred hits and the bounce rate is about 97%. That's all fine and well considering it was free but I would never ever suggest actually buying that type of traffic... seems totally useless to me
