Joel Comm
Joel Comm is an American internet entrepreneur, author, and speaker. He is one of the early practitioners of web-based content monetization and wrote Google AdSense Secrets (multiple editions through 6.0, 2015), which became the definitive practitioner guide to optimizing AdSense revenue on content websites.
Comm built multiple content websites and online properties starting in the late 1990s, which gave him extensive empirical knowledge about display advertising, ad placement optimization, and the intersection of content strategy with monetization.
What the Book Covers
Google AdSense Secrets 6.0 is a technical and tactical guide to optimizing Google AdSense revenue — the system through which website publishers earn money when visitors click on Google-served ads. The book covers:
Ad placement and sizing: The single most important variable in AdSense revenue is not traffic volume but ad unit placement and size. Comm’s key finding from testing:
“The most lucrative ad size, the 338 x 260 rectangle, brought in nearly four times as much: 159 cents for every thousand impressions.”
The general principle: large rectangle ads (336x280 or 300x250) placed within content — not alongside it — dramatically outperform banner ads placed in traditional advertising positions (top of page, sidebar).
“You have to do everything you can to make sure that that ad unit looks absolutely nothing like a traditional banner ad.”
Ad format matching: Ads that blend with site content (matching fonts, colors) outperform obvious “ad boxes.” This design principle conflicts with the conventional assumption that distinguishing ads makes them more visible; in practice, ads that look like content are more likely to be read and clicked.
Contextual keyword optimization: AdSense serves ads based on the content of the page. Pages about high-value topics (finance, insurance, legal services) command significantly higher CPCs than pages about low-value topics. Content strategy can be optimized for this:
“Click the ‘Columns’ button above the table of the Keywords Tool and you’ll be able to add the ‘Estimated Average CPC.’ That shows that on average, advertisers are paying 1.93 for an ad on a page about ‘covered patios.‘”
Revenue structure: Google pays publishers 68% of advertising revenue:
“For ads placed in Web pages, the company passes 68 percent of that revenue to the publisher, and keeps 32 percent for itself.”
Context and Limitations
The AdSense ecosystem has changed substantially since the book’s 2015 publication:
- AI-generated content has changed Google’s content quality standards
- Mobile-first design has changed optimal ad placement
- Privacy regulations have changed cookie-based targeting
- Google’s own platform design has evolved
The principles in the book — contextual relevance, placement within content, matching ad aesthetics to content design, focusing on high-value content topics — remain valid. The specific tactics (exact ad sizes, specific placement coordinates) require updating for current platform capabilities.
The book is most useful as an introduction to the thinking behind display advertising optimization rather than as a current tactical guide.
Relationship to Content Business Models
The book touches on one aspect of the broader content business landscape: earning passive income from content that attracts advertising revenue. This model has been substantially disrupted since 2015 by changes in search algorithms, social media traffic patterns, and advertiser preferences. The underlying economics — create content, attract attention, monetize attention — remain fundamental to many online business models, but the specific mechanism of AdSense optimization has become less central.
