Any ideas about this folks, yup mostly its the blending in & placements that work , but just as a general idea , what do you think would have a better CTR , 3 column or 2 column blogs
I can't speak for Blogger hosted blogs, but I have much better results with 2-column themes. I have been testing with several of my blogs and I can see a dramatic increase in my CTR when using 2-col sidebar right themes.
I've only ever used 2-col themes so i can't give you any advice on which performs better. But I can say as a reader of blogs that I like to see 2 columns rather than 3. I tend to steer away from reading those. There's too many things to look at. I like the 2 column blogs, they're less confusing. It's easier to make a decision about where I want to click and I would assume it's the same way with most blog readers.
