Most popular image sizes?

which should I make?

[David_M]

I'm thinking of adding image ads to my adwords campaigns, but since there are so many sizes available, I'd like to test with the most popular sizes first.

Any info on the sizes which get the most impressions?

I asked this to google directly, but was told- make them all.

It almost certainly varies with both niche and page design.

Why not experiment with YOUR most popular size. Or maybe your least popular size: less risk, more to gain!

728 x 90 px
That is the size that gets the most impressions for me on an image ad basis.

so far this month
728 x 90 px = 108k imps
468 x 60 px = 38k imps
120 x 600 px = 8k imps
160 x 600 px = 7k imps
300 x 250 px = 3k imps
336 x 280 px = 0.6k imps
250 x 250 px = 0.4k imps

all at same bid, same keywords, same ad group, same settings across the board except for image size.

disclaimer: this is just one example that proves nothing to me, make all the sizes and run 'em anyway. generally, the lower imps ones above had higher CTRs, not enough to overtake visitor stats, but certainly worthwhile to have them all in my account.

Great, exactly what I was looking for!
