I was generating a link directly to a specific book title and using the option to create a Text Only link on their web site in associates central.
I went to cut and paste the html code and noticed that they have an IMG SRC command for the text only book link that ends like this:
border="0" alt="" style="border:none !important; margin:0px !important;" /> Looks like they are using a nearly invisible 1x1 image to track page views, and this makes me very worried, because I know one of the old black hat tricks of old was they used to make 1 x 1 pixel images and comment the heck out of them with keyword stuffed alt tags.
What do you folks think about this, is it dangerous to use their code for Google rankling with these 1x1 images?
I would think it 's a one way ticket to sandbox town.
