I opened my email two days a go and found Chitika sent me an email in my inbox, the email contains tip to generate more click in PPC business, the tips are so simple yet very useful and make sense. I believe experienced PPC players use this to increase click-through rate and you should consider using them too, here are the tips:

1. Go Blue: For 15 years now, the human brain has been taught to click on blue links. Blue links have higher CTR (our eye tracking studies have proven this). If your website does not use blue links, you are leaving money on the table.
2. Go White: A non-white background might look cool (specially with kids), but it is completely non-intuitive for advertising and making money.
3. Go Green: And finally, if you are looking for a minty-fresh ad unit that produces some nice green dollars, check out the new mega unit from chitika (see image below)

Hope you’ll find these tips useful and good luck, see you again.
