You may have noticed I have start to use advertisements. Yes, I have sold out.
To the right you will see Google Adsense. This display random adverts vaguely connected with the content of the page. I first ventured into the world of Adsense back in 2004, now I have just revisted my account.Over the last seven years, I have earnt just over £4. Not bad when you consider that I stopped displaying the ads on my websites back in 2004. I know that there are old versions of my sites lurking on various ex-hosts of mine, I assume that some of these still display my adsense adverts, and occasionally someone comes across one and clicks on it.
Another possibility is that someone has mistyped my account number into their advert. Whichever way, I have been getting free money for the last few years 🙂
