well, it all depends on your goals: if you just need "blind" traffic in order for your website to look promising for a future buyer, then yes, you can try buying traffic. but in order to get good quality traffic (eg if running an online store, you'd need also buyers, not just visitors) you'd better try building that traffic yourself: SEO, blogging, listing in price comparison directories (pricerunner.com, shopmania.com, there are many others) and all sort of social media optimisation techniques will deliver results.
not overnight, but reliable results, nevertheless
