Tools for people who work for themselves.

This tool cannot tell you whether Google will approve your site. Approval turns on human judgement about content quality, and no automated checker can stand in for that. You get technical facts, plus an honest explainer of everything else Google weighs.
15 free calculators
Freelance & creator calculators
Pricing, proposals, difficult clients, retainers, tax reserves, overdue invoices, irregular income, runway, time off, side-hustle viability and publishing revenue — with the buffers real independent work needs. Everything runs in your browser.
Pricing & Quoting

Clients & Negotiation
What to say when a client pushes on scope, price, deadlines or payment.

Cash Flow & Getting Paid
Keep the tax money separate and chase what you are owed.
- Feast & Famine Salary MakerTurn wildly uneven client income into one steady amount you pay yourself monthly.
- Tax Set-Aside CalculatorSplit each payment the moment it lands so the tax money is never spent.
- Invoice Late Fee CalculatorLate fee, daily interest and a copy-ready reminder for an overdue invoice.
Planning Ahead
Time off, quiet months and gaps between clients don't fund themselves.
Is This Worth It?
Honest diagnostics on whether a side project, or the hours it eats, is paying you back.
What gets checked
Serving basics
HTTPS without an insecure fallback, a parseable ads.txt, a robots.txt that doesn't shut Googlebot out, and a discoverable XML sitemap.
Page and policy signals
A mobile viewport tag in the head, and whether your homepage links to about, privacy, contact and terms pages — plus a rough word count of visible text.
Speed
Google PageSpeed Insights performance scores for mobile and desktop, run against the same URL you submitted.
What it deliberately doesn't do
There's no score, no percentage and no overall verdict — not because we couldn't compute one, but because any number would imply a certainty this tool doesn't have. Results are split into checks that pass or fail on fact, and a written section covering the things only a human reviewer at Google can weigh.
What AdSense reviewers may reject
Technical faults are the cheapest problems to fix, but they're rarely the whole story. In practice most refusals come down to the same short list, and only one of them is something a checker can measure for you.
Low value content
The most common refusal. Pages exist, but they restate what's already on the web without firsthand experience, original data, or a reason to visit this site rather than another.
Too little of it
There's no official page count, but a site with a handful of short pages gives a reviewer nothing to judge. Depth on a narrow topic beats a thin page on twenty.
Missing policy pages
About, Contact and a Privacy Policy that names advertising cookies are expected on any site carrying ads. A missing one is easy to fix and easy for a reviewer to spot.
Navigation a reviewer can't follow
If pages are only reachable through search or a sitemap, a human reviewer may never see them. Every page worth counting should be linked from somewhere visible.
Under construction
Placeholder text, empty categories, broken links and dead sections read as an unfinished site — regardless of how good the finished pages are.
Technical faults
No HTTPS, a robots.txt that blocks Googlebot, a missing viewport tag, or pages too slow to be usable on mobile. This is the part the checker measures for you.
