How to tell if an ad sells
The Library does not show sales, but it leaves three signs: the ad keeps running for months, the same creative shows up in many ads and the text gets new versions.
The three signs
Look for all three together.
- 1Time runningNobody keeps an ad that loses money running for months.
- 2The same creative in many adsWhen a video sells, it gets copied to more audiences.
- 3New versions of the same textSellers test headlines and buttons without touching what works.
Look at the offer, not one ad
One ad is only a part. The offer may have dozens, on different pages. Add up the time and the ads of every page before you conclude.
Questions and answers
- How long running means an ad sells?
- Months, not weeks. Whoever is losing money turns the ad off quickly.
- Does an old ad always sell?
- No. It is a sign, not proof. That is why UltraSpy puts the signs of the whole offer into a score from 0 to 100.
