Run experiments to measure the effects of advertising (and make money)

Readers of this blog know that we are big fans of randomized control trials (RCT's).  Here is a story from a new book, The Power of Experiments, taken from a review by Strategy & Business.

 eBay used to pay Google about $50 million annually for ads by search terms that included the company name, such as eBay or eBay shoes. To determine whether this was worth the money, they ran an experiment, turning Google ads on and off, and tracking the traffic coming to eBay from Google ads (paid) vs. traffic coming from organic search (unpaid). They discovered that paid advertising was cannibalizing traffic from organic search:
...the experiments found that in markets where the company didn’t advertise, it got a spike in traffic from unpaid organic links. “Evidently, users who Googled ‘eBay’ (or another eBay-related search term), who had been clicking on the ad because they saw no reason to scroll down to the organic link just below it, were now instead clicking on the first organic search result.

  1. A GREAT SPELL CASTER (DR. EMU) THAT HELP ME BRING BACK MY EX GIRLFRIEND.
    Am so happy to testify about a great spell caster that helped me when all hope was lost for me to unite with my ex-girlfriend that I love so much. I had a girlfriend that love me so much but something terrible happen to our relationship one afternoon when her friend that was always trying to get to me was trying to force me to make love to her just because she was been jealous of her friend that i was dating and on the scene my girlfriend just walk in and she thought we had something special doing together, i tried to explain things to her that her friend always do this whenever she is not with me and i always refuse her but i never told her because i did not want the both of them to be enemies to each other but she never believed me. She broke up with me and I tried times without numbers to make her believe me but she never believed me until one day i heard about the DR. EMU and I emailed him and he replied to me so kindly and helped me get back my lovely relationship that was already gone for two months.

    2. Hi viewers online, I'm Suzanne Gratton from the US. I'm here to share my testimony about how I helped to get my husband back. I was a cheat and my husband caught me several times. I tried fixing myself and each time I ended up cheating over and over again. I guess I didn't realize what he meant to me until he had left me alone. I began to find a way to get him back but nothing seemed to work out perfectly until I came across an article about DR PATRICK who helped a lot of people globally to get their relationships back. I made contact with him and he assured me that my husband will come back to me within 48 hours with his powerful magic and I paid 410 dollars for the materials needed for the work. Surprisingly, my husband came back home after 2 days saying that he still loves me and I swore never to cheat on him anymore. All thanks to DR PATRICK. You can have a chat with him on his WhatsApp number +1 662 493 2087 or you can contact him on Email drpatrickspellcaster@gmail.com and here is facebook page https://www.facebook.com/Drpatrickspellcaster11 and his blob https://drpatrickspellcast.blogspot.com
