The space ads are taking up is slowly increasing from the side bar into the articles and the content seems to be going against your own guidelines as being relevant to your site content. It's starting to be "spot the stuff that Dave did".
I don't mind having ads and I understand why they're there, but acne treatments and mattresses?
They are Google Adsense ads, and that's how the system works.
I do not get a say in what ads are displayed there, Google chooses what to display based on who you are and your browsing history.
If I search for baby stuff today, google knows that and I get baby ads on my own site.
Some are not targetted ads though, they are more traditional "spam" ads, but they are lot more expensive to the advertiser. And the advertiser usually choses specific sites they want ads to appear.
e.g. on youtube you might get a blasted with the latest movie trailer when a movie is coming out, regardless if google thinks you like movies or not.
Right now I get a Digilent FPGA ad, the Perth Mint, and Kogan. All three of which I have searched for recently on Google.
Our Google overload knows all
Dave.
