No, it’s HTML and it’s an Amazon affiliate link which is acceptable. My husband has a free WordPress blog and I posted the banner there flawlessly using the Text widget as normal. The only difference in our blogs is that mine is a premium theme (it’s the Lens theme and I also purchased the Custom Design upgrade) and his is free. I’d use WordAds if they would accept me into the program lol! I can’t seem to catch a break.
