Worked example: diagnose a noindex landing page
Illustrative HTML, not a real customer result: the page below has a title and H1, but also noindex. If this is a public landing page you intend Google to index, investigate the template or CMS setting that added noindex. If the exclusion is intentional, keep it. Do not apply an SEO checklist indiscriminately to private or duplicate pages.
For an illustrative weighted SEO ratio of 0.8, the curve produces 68. A failed indexable critical check caps the SEO dimension at 55; removing the accidental exclusion removes that cap. It changes this diagnostic, not the number of search visits.
<title>Product guide | Example</title>
<meta name="robots" content="noindex">
<h1>Product guide</h1>Verify the change with evidence, not only a score
Save the old scan date, exact URL and failed check evidence. After updating the public page, confirm that the initial HTML or X-Robots-Tag no longer contains the accidental noindex rule. Use Search Console URL Inspection to check crawl and indexing status; submit an indexing request only when the URL should be indexed.
Then compare clicks, impressions, CTR and query positions over comparable periods. Watch completed analyses and report requests for traffic arriving from search. This separates technical fixes from changes in search demand and conversion.
Step 1: run a free check
Paste a public domain or page URL into the SEO checker. You first see an overall score across eight areas, without an account. Email unlocks the SEO breakdown and full report. Three successful analyses per network are free each UTC day. Test the page that receives search traffic, since a page scan does not audit every URL on your site.
Step 2: read the score correctly
A score of 90+ is excellent and 70+ is genuinely solid on a demanding scale. But the number depends entirely on what's checked: a permissive tool that only inspects your title tag hands out 95s freely, while a strict one that weighs indexability, canonical tags, structured data and heading structure is much harder to satisfy.
Also know what no SEO score can see: backlinks, domain authority and your actual rankings are off-page factors invisible to a page scan. Treat the score as a checklist of what you control on the page — not a prediction of where you'll rank.
Step 3: fix the highest-impact items first
The fixes that move a score (and results) fastest, in order: make sure the page is indexable at all (no stray noindex, a reachable sitemap); write a unique 30–60 character title with your keyword near the front; add a 120–158 character meta description; keep exactly one H1 and a logical heading outline; add JSON-LD structured data; and declare a canonical URL.
These are the items a checker can verify objectively — and the ones Google's own documentation keeps pointing back to.
Step 4: check the dimensions SEO tools skip
Review performance, accessibility and security alongside your on-page SEO checks because they affect the visitor experience. The GEO score adds access, content structure and attribution heuristics. These scores are useful diagnostic checklists; they are not Google's ranking scores or measurements of actual AI citations.
Re-check after each round of fixes. The before/after delta, on the same tool, is the only score comparison that means anything.
