Slashdot Mirror
A Closer Look at Google Adwords
zaphle writes "This article describes an interesting experiment with the Google Adwords service; in an effort to fine-tune the price per word, a mirror site was set up, paying a different price per word. I turns out the second site had to pay more in order to reach a similar click-through rate. My questions to the slashdot community: are organizations like Google redefining the law of demand and answer? To what extent does this imply a competitive advantage for larger companies? Do we need an ethical framework to direct companies to make such algorithms open source?"
Just a speculative thought because no one really know about googles algorithms.
The result may be due to the original pages higher pagerank. I wouldn't be surprised if google would give higher position to "better" sites even in ads. In Googles context, higher pagerank means "better" site.
My quality social news site.com.
I have an alternate explanation. I believe what existed before the guy's experiment was a more-or-less stable "ecology" around those particular keywords. There were probably a number of people paying a premium for a limited number of clicks for those keywords, well above the 10-cent level he was originally paying for. Google probably sorted the higher-paying advertisers onto the best pages and left the dime-a-click ones for others and everyone was more-or-less happy.
Then when the experiment began, it disrupted things. The advertisers who were initially offering a premium found themselves with fewer clicks as their ads were placed on less advantageous pages, or when their ads were displaced entirely. They then changed their own behavior, perhaps by choosing different keywords and/or paying higher rates. This would have cascaded, causing other advertisers to change their behaviors.
The end result would've been a shift in AdWords' performance with those keywords, one that wouldn't easily be reversible, and which could account for the poor performance when the experimenter reduced his bids for clicks.
I skimmed this and thought, "Hmm, this looks like the kind of text that would be generated by a script." A couple of minutes of searching (via Google, ironically enough) turned up the Automatic Complaint Generator.
Sigh. Remember when trolling was an art form, when people would put time, effort, and (dare I say it?) heart into inciting flame wars, even when posting as Anonymous Cowards. The kids these days are just phoning it in, and that saddens this oldtimer's heart.
I was thrilled with the ad-block extensions of Firefox, and welcomed the relevant ads from google. I'll admit, I have actually clicked on, and even (shocked) bought a few things.
I hate desperate ads, like those on TV and everywhere else. Advertisers realise that they are failing.
When/if google starts flash, popups, then start to complain.
Tired of online retailers charging extra to ship products to Alaska?
First of all if he gets 15000 @ 0.15 clicks per day he is paying $1500,- a day in advertising that is $547.500 per year in advertising alone. His friend must be an internet miljonair! I somehow doubt that such a large operation would execute the test as described in the article. I think the figures are a bit inflated to make it a better story. Furthermore I use Google Adwords for my company (http://www.tiouw.com/). I spend around $5000 a year on Google. As everyone who has ever worked with AdWords knows is that when you change your ad, it changes your click through rate. Changing URL's, text, anything has a direct result. It takes some time before the system gets used to the changes and then you are back on track. I expect that if the company in the article would have run for some time with the new settings it would generate more and more hits. Finally, tests have shown that people do not click on the no.1 position, but prefer no. 2 or 3.
On the contrary, Cringley has utterly misinterpreted these results and they actually prove that you should not do these tests.
If Google does anything with AdWords the obvious thing to do is examine the BIDS for AdWords that it receives and figure out a VALUE for each AdWord.
By setting up a rival site and BIDDING AGAINST HIMSELF this guy drove up the VALUE of his AdWords.
How is this not obvious? Google just coded the free market.
