I have a general question about adverts: if you are using paid web hosting, what might be the reason for using something like Google Adsense or Amazon adverts on your site? Is there any reason to have it or would it make your site look like a non-paid site?
And how do these work? I know that Google Adwords is a pay-per-click service but I'm not sure about the other two.
The reason for using them is the same regardless of the type of site they reside on: to make money. For somall sites it is often just to deefray hosting costs. For otyhers a major income stream. Amazon is an affiliate program. Details on their website.
