Discovering the element of AdSense
Discovering the element of AdSense

As traffic grew, he began to explore how he could start earning ad revenue. "I tried a few tools from different ad tech companies, different brokers, and a few affiliates," he shares. "I chose AdSense because it gives me the most control over the types of ads that are shown, and that's really important to me from a user experience standpoint for an education site." Plus, he adds, "every year I see a new peak in revenue – increases of 10-15% each year – which is great not only because this is my main source of earned income but also because it's really motivating. Seeing the site's audience grow and the revenue grow makes me want to keep doing more."

“I started this site as a way to make science education more interesting and allow students to ask deeper questions with a periodic table, and I was able to turn it into a business using ad revenue. Now I serve over 15M students and educators each year, and I'm able to make the site accessible to all with a free, ad-supported model.”

Keeping access free for students

Keeping access and performance in focus has also helped Michael make an impact right in his community. "There's a local teacher here in Knoxville who always recommends the site to his students, and I've actually gotten to meet some of them through my volunteer work. It's pretty amazing to hear them talk about how they find the site helpful and know that their teachers find it a valuable, trusted resource. It's a real point of pride in my life, to have created something that millions of people trust and use each year."

About the Publisher

Michael Dayah is a programmer living in Knoxville, Tennessee. He previously worked for FlightAware developing their interactive, pan-and-zoom mapping. Not ready to move across the country, he left to focus on an almost-abandoned decades-old side project that had been slowly climbing in organic rankings, expanding it to include lesson plans, posters, and wallet cards. AdSense allowed him to pursue this full time.
