4. Content quality signals

• Every indexable language editor page (e.g. /online-python-editor) ships with 350+ words of hand-written educational content, build-validated by scripts/validate-prerender.mjs.
• All editor pages carry a human author byline ("Reviewed by Aryan Gautam") linking to /editorial-policy.
• Unique <title> and <meta description> per route, enforced by the same validator.
• Long-form editorial articles published on /blog, each with named author, publish date, and references.
• Thin SEO variants (/compare/*, /best/*, /for/*, *-fiddle, *-playground, etc.) are explicitly noindex and canonicalized to their primary page.

5. Ad placement disclosure

• Ads are served via Google AdSense only — no other ad networks.
• At most one ad slot per page, rendered below the fold, clearly separated from primary content.
• Ads are excluded from interactive / utility surfaces: /auth, /login, /signup, /checkout-success, /account, /admin, /editor/*, and /projects/*.
• No ads on auto-refreshing, pop-up, or interstitial surfaces.
• No incentivised clicks; no encouragement to click ads anywhere in the UI or content.
• ads.txt declares only Google as an authorised seller.

6. Technical SEO proof
