I registered for and implemented Google AdSense on this website today. So certain pages will now display advertisements related to the page content, or at least that's the theory. In practice I'm not too sure how successful it will be. Within seconds of adding the relevant code to my carbon paper essay, Google chose to display two ads for quill pens (the essay does mention the quill pen, but I'd no idea you could still buy them).
I decided to sign up for AdSense because every few weeks someone writes to me via email and enquires about purchasing some carbon paper. Just today I received a request for a box of 500 sheets from someone in Alexandria, Egypt. Egypt was also the source of another request a few months ago, but that one was for 15,000 tons of the stuff!
As much as I'd like to help these people, I'm not in the carbon paper business. So I thought that the relevant ads from Google might prove useful to anyone searching for carbon paper who stumbles across my site. And who knows? It might even generate sufficient revenue eventually to cover the cost of this site.
So if you're ever in the market for a new quill pen, you know where to come.
