Advertising! 20 reasons to keep doing it.

In 1885, Thomas Smith, a 19^th century London businessman, offered this advice to his advertisers and it’s still true today:

1. The first time people look at any given ad, they don’t even see it.
2. The second time, they don’t notice it.
3. The third time, they are aware that it is there.
4. The fourth time, they have a fleeting sense that they have seen it somewhere before.
5. The fifth time, they actually read the ad.
6. The sixth time, they thumb their nose at it.
7. The seventh time they start to get a little irritated with it.
8. The eighth time, they start to think "there’s that confounded ad again."
9. The ninth time, they start to wonder if they may be missing out on something.
10. The tenth time, they ask their friends and neighbors if they have tried it.
11. The eleventh time, they wonder how the company is paying for all of these ads.
12. The twelfth time, they start to think that it might be a good product.
13. The thirteenth time, they start to feel that the product has value,
14. The fourteenth time, they start to remember wanting a product exactly like this one for a long time.
15. The fifteenth time, they start to yearn for it because they can’t afford to buy it.
16. The sixteenth time, they accept the fact that they will buy it sometime in the future.
17. The seventeenth time, they make a note to buy the product.
18. The eighteenth time, they curse their poverty for not allowing them to buy this terrific product.
19. The nineteenth time, they count their money very carefully.
20. The twentieth time that prospects see the ad, they buy what it is offering.

In other words if your ad campaigns aren’t showing a return after 6 weeks, don’t give up hope! Persistence pays!
