About CostZap
CostZap is a free suite of online calculators and SEO tools built for content creators, publishers, bloggers, and webmasters. Our mission is simple: make powerful digital tools accessible to everyone — no paywalls, no signups, no limits.
Whether you're a beginner trying to estimate your first AdSense paycheck or an experienced publisher optimizing a multi-site portfolio, CostZap gives you the data you need to make smarter decisions, faster.
Why We Built CostZap
When we started out as content creators, we constantly found ourselves jumping between spreadsheets, browser tabs, and half-broken tools just to answer basic questions: How much could I earn if I get to 100,000 page views? Is my keyword density too high? Will my title tag get cut off in search results?
None of the existing tools quite hit the mark — they were either behind a paywall, cluttered with ads, required a signup, or simply gave inaccurate results. So we built our own. CostZap started as a small collection of internal tools and grew into a full platform used by creators, SEO professionals, and publishers worldwide.
Today CostZap covers everything from ad revenue estimation to technical SEO, UTM tracking to structured data generation — all in one place, all free.

Our Values
Free Forever
Every tool on CostZap is completely free to use. There are no premium tiers, no feature locks, and no credit card required. We believe the best tools should be available to everyone — not just those who can afford a subscription.
Privacy First
All calculations happen entirely within your browser. When you type a number into our AdSense calculator or paste text into our keyword density checker, that data never leaves your device. We don't log your inputs, and we don't store your results. What you calculate stays yours.
Accuracy You Can Trust
Our calculators use industry-standard formulas and regularly updated benchmarks. We cite our sources, explain our methodology, and flag where estimates are exactly that — estimates. We'd rather give you an honest range than a falsely precise number.
Fast and Focused
We designed CostZap to be as fast as possible. Tools load instantly, calculations happen in milliseconds, and there's no unnecessary complexity. Every feature on the page earns its place.
Constantly Improving
We actively maintain and expand CostZap based on user feedback and changes in the digital marketing landscape. When Google updates its algorithm, when ad network rates shift, when new platforms emerge — we update our tools to keep up.
