Purpose
ROAS Lab publishes free calculators and educational guides that help marketers and business owners understand advertising economics. Our content is explanatory and planning-oriented; it does not replace accounting, tax, legal or investment advice.
Standards
Each guide should answer a clear user question, explain its formulas, define assumptions, and include a worked example where useful. We avoid inventing statistics, clients, case studies or results. Illustrative scenarios are labeled as examples.
Review process
Material is checked for mathematical consistency, readable structure, internal link relevance and alignment with the calculator it supports. A visible review date indicates when the page was last substantively checked. Updates may be triggered by formula errors, unclear language, broken links or meaningful changes in advertising practice.
AI-assisted production
Automation and AI tools may assist drafting, formatting and image production. They do not change our standard: published material must remain useful, internally consistent and free from unsupported claims. Decorative article images are illustrative and are not evidence or screenshots of actual campaign performance.
Corrections
If you identify a possible error, send the page URL, the disputed statement and supporting context through our contact page. Confirmed material errors are corrected rather than silently defended.
Commercial independence
Advertising may help support this free website. Advertising placement does not determine calculator results or the conclusions of editorial guides. Any future affiliate relationship or sponsored material should be clearly disclosed on the relevant page.
