It has been known over the years that wider ad formats tend to outperform their taller ads, due to their reader-friendly format. Readers are able to absorb information in "thought blocks" (a block would be for example a few words at a time. Usually 7 words.).
Wider ad formats allow readers to read comfortably without having to move down the lines like a story book. Knowing this is one thing but applying it will make a whole lot of difference to your blog or web page. With the wide ad format, you will not only be making your ads more appealing to your readers but also it will make your web page look more clean or neat! WIN WIN!
If positioned well, these ad formats can increase your earnings significantly. The formats that are found to be the most effective by google are the:
- 336x280 Large Rectangle
- 300x250 Medium Rectangle
- 160x600 Wide Skyscraper
Be well aware that even though these ad formats tend to perform the best, you should use the format that best complements your pages.
Just a little tip: Try on a simple streamlined ad like the link units! Image below
