About GreenLight
GreenLight is a plain-language second opinion for any live website. It checks the things that quietly hold a site back after launch, and explains each one so you learn, not just patch.
What it does
Most site tools are powerful but cryptic: walls of jargon, severity scores, and acronyms. GreenLight's whole job is the last mile: it tells you, in plain language, what we noticed, why it matters, and how to fix it. You point it at a live, public URL and it reports back like a helpful colleague, not a dashboard.
Why I built it
GreenLight came out of a problem every new site owner hits, but few solve. I launched mygoldfinger.com and applied for Google AdSense. It came back with the same vague “low value content” rejection that bounces the large majority of new sites, with no explanation of what to change. Search Console worked the same way: warnings that name a symptom but never the fix. These systems are deliberately opaque.
So I reverse-engineered what they actually reward: the security headers, the E-E-A-T and authorship signals, the content depth, the structured data, and the order you have to tackle them in. The tools that were supposed to help only handed back more jargon, so I built my own: checks that name the exact problem and the exact fix, in plain language, for your specific site.
That became GreenLight. It’s the decoder I wish I’d had on day one: a plain-language second opinion that tells you what’s wrong, why it matters, and exactly how to fix it, so the next person doesn’t lose weeks to a fuzzy rejection.

The toolkit
Seven tools, each a whole-site scan in plain language:
- Security. The common basics: HTTPS, HSTS, the protective response headers (CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy), mixed content, cookie flags, and exposed sensitive files. A scan, not a hardening guarantee.
- SEO. Title and meta description, a single clear H1, image alt text, mobile viewport, canonical link, page language, a sitemap, duplicate titles and descriptions across pages, and thin-content warnings.
- AI Search (GEO). Whether AI engines like ChatGPT, Perplexity, and Google AI Overviews can find and cite you: an llms.txt file, access for the AI citation bots, structured data (FAQ, Article, HowTo), question-style headings, and interlinked articles.
- AdSense readiness. The practical hurdles to ad approval: a privacy policy, About and Contact pages, a valid ads.txt, crawlability for Google, and enough real, original content, including the E-E-A-T checks drawn from real rejections.
- Accessibility (ADA). Mechanical WCAG basics: image alt text, buttons and form fields with real labels, a main landmark, and a page language, so screen readers, voice control, and search all read the page.
- Speed signals. The markup and server signals behind a fast page: server response time, text compression, heavy HTML, render-blocking scripts, and images missing dimensions or lazy-loading.
- Social readiness. How a link looks when shared: Open Graph and Twitter/X cards, a preview image that actually resolves, a favicon, and linked social profiles.
A rule-breaker, not a challenger
GreenLight doesn't try to replace Google Search Console, AdSense, or a full security audit. It sits alongside them and fills the gap those tools leave. To borrow a framing from David Gardner of The Motley Fool, it's a rule-breaker: it doesn't reinvent the wheel, it breaks the one rule every other site tool follows: that finding a problem should cost you hours of hunting. The others flag that something is wrong and leave you to search for it. GreenLight hands you the page, the element, and the exact fix, in plain language. It's built to save your time, not spend it.
Built to teach
Every finding is written to be understood by someone who isn't a specialist. A missing header isn't just flagged. It's explained: what the header does, why its absence matters, and the exact line to add. New site or established, GreenLight is meant to be worth a double-check and a quick lesson each time.
We run it on our own site
We run GreenLight every day on the very site it grew out of, mygoldfinger.com. The logged-out demo you see is a real scan of mygoldfinger.com. We eat our own dog food: when GreenLight finds something, we log it as Challenge, Action, Result and fix it in the open.
Honest limits
GreenLight reads what a page serves; it is a best-effort scan, not a full audit and not a guarantee a site is secure or perfectly optimized. It checks the common, high-value basics (the ones most sites actually get wrong) and is upfront when something is a heads-up rather than a must-fix.
