SEO Score Report
What is SEO and Why Does It Matter?
An on-page SEO score is a single number — typically expressed on a 0 to 100 scale — that summarises how well a single web page implements the technical and content-level signals that search engines and AI answer engines look for. It is the SEO equivalent of a credit score: it doesn’t guarantee a particular outcome, but it instantly tells you whether the fundamentals are in place.
When Googlebot or Bingbot first encounters one of your URLs, it reads the raw HTML. Within milliseconds it tries to answer four questions: What is this page about? Who is it for? Is it safe? Should I show it on mobile? The answers come from a small set of on-page signals — your title tag, your meta description, your headings, your alt text, your viewport tag, your canonical link, your HTTPS status, and your robots directive. RankifyPro audits all of them at once.
The same signals matter for AI engines. ChatGPT, Gemini, Perplexity and Microsoft Copilot don’t crawl the web in real time the way Google does, but the documents they cite were originally indexed using the same fundamentals. A page with a clean title, a real H1, a sensible meta description and an FAQ section is dramatically more likely to be retrieved and quoted than one with broken HTML or thin metadata.
How Each Check is Calculated (Editorial Transparency)
1. Title Tag
We read the contents of the <title> element. Pass: 40–65 characters. Warn: present but outside that range. Fail: missing entirely.
2. Meta Description
We read the content attribute of <meta name="description">. Pass: 120–160 characters. Warn: present but outside that range. Fail: missing.
3. H1 Heading
We count all <h1> elements. Pass: exactly one. Warn: more than one. Fail: none.
4. H2 Headings
We count all <h2> elements. Pass: two or more. Warn: exactly one. Fail: none.
5. Image Alt Text
We iterate over every <img> on the page and check the alt attribute. Pass: 100% coverage. Warn: partial coverage (with a percentage progress bar). Fail: no images have alt text. Info: no images on the page.
6. Mobile Viewport
We look for a <meta name="viewport"> tag. Pass: present (and we display the content value). Fail: missing.
7. Canonical Tag
We look for <link rel="canonical">. Pass: present. Warn: missing.
8. Page Load Speed
We measure HTML response time in milliseconds. Pass: < 800ms. Warn: 800–2000ms. Fail: > 2000ms.
9. Keyword Density
We strip HTML, split visible text on whitespace, and count occurrences of every word longer than four characters. The top word’s share of total words is the density. Pass: 1–3%. Warn: above 3% (possible stuffing). Info: below 1%.
10. HTTPS / SSL
We inspect the URL scheme after redirects. Pass: https://. Fail: http://.
11. Open Graph Tags
We look for at least an og:title meta property. Pass: present. Warn: missing.
12. Robots Meta
We look for <meta name="robots">. Pass: present and not noindex. Fail: contains noindex. Info: absent (defaults to indexable).
The total score is the sum of awarded points (10 for pass, 5 for warn, 0 for fail) divided by the maximum possible, expressed as a percentage. Info checks are excluded from the denominator so they don’t penalise pages that legitimately have no images, for example.
How to Check
Open the SEO checker
You’re already on it. Bookmark this page so you can return to it during your monthly site audits.
Paste your URL
Use the full URL including https://. Audit one page at a time — homepage, top blog post, top landing page, etc.
Click "Check SEO Score"
The button is disabled while the audit runs. You’ll see a spinner; results auto-scroll into view.
Read the score and grade
0–39 red, 40–59 amber, 60–79 blue, 80+ green. The dial animates from 0 to your actual score.
Sort fixes by impact
Red "fail" cards = highest priority. Amber "warn" cards = next. Blue "info" cards = lowest priority.
Re-test after each fix
Apply the fix in your CMS, clear any caches, and run the same URL again. The score will climb in real time.
Security & Privacy
The URL you submit is fetched once, parsed in memory, and immediately discarded. There is no audit history, no email collection, no remarketing pixel firing on the audit endpoint. Read our full Privacy Policy and Cookie Policy for the long-form disclosure.
Our crawler identifies itself as Mozilla/5.0 (compatible; RankifyPro/1.0; +https://rankifypro.com) in the User-Agent header so server-side log analysis tools can see exactly where the request came from.
Frequently Asked Questions
How do I check my website’s SEO score for free?
Paste your full URL into the input field on this page, click "Check SEO Score", and wait 3–6 seconds. RankifyPro will fetch the page, audit 12+ on-page factors, and display an instant 0–100 score with a one-line recommendation for every check.
What is a good on-page SEO score?
A score of 80 or above is considered excellent, 60–79 is good, 40–59 is average (some fixes needed), and below 40 indicates significant issues that should be addressed before promoting the page.
What URLs can I check with this tool?
Any publicly accessible URL that returns HTML — your own homepage, a blog post, a product page, a competitor’s page, or a landing page. Login-protected URLs and pages that require JavaScript rendering to deliver content cannot be analyzed.
Is the tool reliable for technical SEO audits?
The tool is reliable for the 12+ on-page factors it covers. For a complete technical audit you should also run Google Search Console (crawl errors, index coverage, structured-data warnings) and PageSpeed Insights (Core Web Vitals).
Should every page on my site have exactly one H1?
Yes — this is a long-standing best practice. While Google has stated multiple H1s won’t break rankings, exactly one H1 per page produces the clearest semantic structure for crawlers, screen readers, and AI summarizers.
How does the tool measure keyword density?
We strip HTML, lowercase the visible text, split on whitespace, and count occurrences of every word longer than 4 characters. The top word’s percentage of the total word count is the keyword density. Healthy range: 1–3%.
Does this tool check schema markup / structured data?
The current release flags missing Open Graph tags (which use a structured-data-like syntax) but does not validate JSON-LD schemas. For schema validation use Google’s Rich Results Test alongside our on-page audit.
Is the SEO checker open source?
The check logic is documented in detail on our Methodology page. We may release portions of the analyzer publicly in the future.
How is the tool funded?
Through Google AdSense. Advertising allows us to keep every feature free, with no signup wall and no usage caps. We do not sell user data.
