He's doing it wrong, if you look at the impressions he's got adwords set so that if a keyword is doing well it gets more impressions. That's the wrong way to do this set, you have to configure it to give each keyword equal coverage.
Otherwise what happens is that by pure randomness some of your keywords are going to get less clicks than others, and as soon as that happens to one of your keywords they get "frozen" (i.e. they get no more ad impressions so they get stuck at their "random" low value).
Did you de-obfuscate the text, run the searches, or use some other mechanism? I didn't find anything when running the searches and don't really have the time to mess with de-obfuscation
And now this page is the number 1 hit in google for that phrase and some little vector spread across racks of google boxes is wondering why hackers suddenly care so much about Annabel and what they can sell us.
That is actually a pretty clever way to do quick and cheap marketing research. However, not a good way to write a novel. To all aspiring writers: please do not base your novel on marketing research, if I wanted that I would be watching TV.
If the author had A/B tested the headline, it probably would have gotten more clicks as "Naming characters in a novel". The way it reads now, it sounds like something about using non-ASCII symbols in Adwords.
You have to be careful when doing this not to violate Google's TOS. I don't think they like people using AdSense just for "market research" because the users who actually click on the link get taken to a useless landing page. Unless he had a pre-order form for the book as the landing page, that's not generally accepted. I know Tim Ferris kind of popularized that technique, but if all of Google's Ads lead people to worthless landing pages, their CTR across the network would go down. Just an FYI for those who can't afford to get a Google Ban because they also rely on AdSense.
Your ads and keywords must directly relate to the content on the landing page for your ad. When users see your ad, they should be able to understand what kind of product, service, or other content they will find on your site. Products or services promoted in your ad must be reflected on your landing page; ads can be disapproved if a promoted product is not offered or available for sale as promised.
The ad doesn't promise that anything is for sale - it seems like a general branding campaign.
Why do some of the ads get run more often than others? Seems like google would run the one with the highest click through rate more often. I'm not convinced all of these are statistically significant anyway, but I don't have R at the moment.
There is a setting in Adwords for "rotate my ads evenly over time" that is necessary for accurate A/B testing. By default, Google shows the ads with the highest click rate more often, so you'll get a bias.
