Editorial standards
MarsGeo is operated by Mars LLC. This page explains who makes our tools and content, how we verify it, and how we handle corrections.
Who we are
Mars LLC builds free, browser-based SEO tools and writes practical guides about structured data, technical SEO and AI search. Contact: [email protected].
How our tools work
The generators and checkers are deterministic: they run in your browser, produce standard output (JSON-LD, robots.txt, XML, meta tags) and are tested against the official specifications and Google's Rich Results requirements. We do not collect the HTML or data you paste into the free browser tools.
How we create content
- Each guide is written to answer a specific search intent and is reviewed before publishing.
- We cite primary sources (Google documentation, schema.org, vendor docs) and avoid unverified claims.
- We date every article and update it when the underlying guidance changes.
- Comparison pages state that pricing/features change and point readers to the vendor's own site.
- We do not publish fake reviews, fabricated data, or pages with no unique value.
Corrections and updates
If you spot an error, email [email protected]. We review reports, correct factual mistakes, and note material updates. Pages that are no longer accurate are revised or removed rather than left stale.
Advertising and independence
Free tools stay free. Paid plans add volume and automation. Where ads are shown, they do not influence our editorial recommendations; we do not sell rankings or reviews. See our Privacy Policy and Terms.
