Something new for consideration with your Google Adwords accounts.
Now, the ad rotation setting which allowed multiple ads to run indefinitely has been discontinued as of mid-May.
So, after 30 days of testing, Google will only run your ad with the highest number of clicks.
Be careful with this feature as the ad earning the most clicks might not be the ad earning the highest number of sales, conversions, etc.
It makes sense Google wants the best "clicked" ad to be presented the most often (that's how it makes money), but it might not be the best ad for your business.
Keep an eye on your ads, clicks and conversions.
