Pay per click advertising is usually the most effective and profitable form of marketing available to online businesses. The reason for this is that, as the name implies, pay per click advertising only charges you for the actual clicks that you receive. What this effectively means is that you won’t be charged for adverts that aren’t effective in getting seen or getting clicked. As a result, PPC provides you with a way to get completely free exposure as well as to generate highly targeted traffic to your website, landing page or brand.
PPC is incredibly powerful and big companies will invest millions into it because it provides such huge returns. Amazon has been known to spend over a million dollars a day on AdWords, which should give you an indication of just how successful it can be.
