i absolutely need your input, which's the best or good for increasing the earning between Leaderboard (Text Ads) or Leaderboard (Image Ads)? please share your experience.
Text ads always did the best as image ads is too obvious ads for everyone. Many people believe the text ads are part of your website if you integrate it properly. Personally, a large rectangle or normal rectangle placed in middle of an article text or next to a videoclip seems to give me best CTR, not amazingly high, around 3-5%, sometimes higher, but that ain't bad. Best of luck!
IMO, Image Ads works well on entertainment related site and Text Ads work better on sites with good content.
