Google Adwords Experiment: What Spelling Of \"Ebook\" Gets The Highest Response?

And the higher up the page your ads are, the more traffic you're likely to see!

Ebooks also are hot property with many people making sizeable incomes from selling them, often using Google Adwords as a primary source of traffic.

So a critical question right now is what are the smart marketers doing to boost their Adwords ads for ebooks so dominating their market *without* spending a fortune?

I decided to test out an advert for my Ebook Sales Assistant product using the following advert:

Creating An Ebook? Learn how to build an ebook sales site. 100 page ebook tells all.

Keeping the text of the advert identical, I split tested 3 version of the headline to test whether the spelling Ebook, ebook or eBook would get the highest response from users.

Over the course of the experiment the ad was shown an impressive 71,129 times so the results are highly significant.

The results:

Creating An Ebook?: 0.9% CTR Creating an ebook?: 0.9% CTR Creating An eBook?: 0.4% CTR

So the results show that I found no difference in response rates between the spelling Ebook or ebook but the spelling eBook had a very negative impact on my ad response rate, getting less than half as many clicks as the other two ads with identical text.

There are two morals to this story:

1) When using pay per click advertising, if your ad contains the work "ebook" never spell it as eBook

2) Also note how *huge* the difference in response rates are. Be aware that something as simple as changing which words have capital letters and where abouts in the word they are can have a massive effect on results. So get experimenting!

Lastly, when testing my most successful ads on just Google rather than associated content sites (those displaying Adsense ads) my clickthrough rates jumped to an average of 2.9%.

And that's without actually testing different ads, just changing the capitalization.
