Part 3/7:
With 4.5 million visitors per month and an impressive average of 1.55 pages viewed per visitor, the potential for revenue skyrockets. Display ads contribute substantially to its coffers; even estimating a conservative RPM (Revenue Per Mille or revenue per thousand visitors) of $5, unitconverter.net rakes in over $35,000 monthly. Approximately 80% of its traffic is derived from organic Google search, where the site ranks for popular keywords like "inches to feet" and "kilometers to miles".
This example sets the stage for understanding how overlooked niches can yield significant earnings, particularly through effective search engine optimization (SEO).
