Analyzer Metrics Reference

Detailed explanation of every metric displayed in the page analyzer tool.

Overall Score

The overall score is a weighted calculation (0-100) that evaluates multiple aspects of your page:

• Title & Meta: Presence and quality of title tags and meta descriptions
• Headings: Proper heading structure (H1-H6) hierarchy
• Content Quality: Word count, readability, and text/HTML ratio
• Technical SEO: HTTPS, canonical URLs, robots directives, security headers
• Social Media: Open Graph and Twitter Card implementation
• Internal Links: Presence of contextual internal linking
• Performance: Page load speed and resource optimization

Page Information

• URL: The analyzed URL (after redirects if any)
• Status Code: HTTP response code (200 = OK, 301 = Permanent Redirect, 404 = Not Found, 500 = Server Error)
• Final URL: The destination after following redirects
• Content Type: MIME type of the response (typically text/html for web pages)
• Render Time: Time taken to fetch and optionally render the page

Title & Meta Information

Title Tag

• Recommended Length: 50-60 characters (~600px)
• Purpose: Appears in search results, browser tabs, and social shares
• Best Practices:
  • Include primary keyword near the beginning
  • Make it unique for every page
  • Write for humans, not just search engines
  • Match search intent (informational, transactional, navigational)
  • Include brand name (usually at the end)

Meta Description

• Recommended Length: 120-160 characters (~960px)
• Purpose: Summarizes page content in search results; influences click-through rate (CTR)
• Best Practices:
  • Write compelling, action-oriented copy
  • Include a call-to-action when appropriate
  • Match the content on the page
  • Make it unique for every page
  • Not a direct ranking factor, but affects CTR

Canonical URL

• Purpose: Specifies the preferred version of a page when duplicates exist
• Usage:
  • Set self-referential canonical on original pages
  • Point duplicate/variant pages to the canonical version
  • Use absolute URLs (https://example.com/page)
  • Ensure canonical URLs are indexable (not noindex, 404, or redirecting)

Heading Structure

• H1: Use exactly one H1 per page as the main heading; should be descriptive and include primary keyword
• H2-H6: Create logical hierarchy; H2 for main sections, H3 for subsections, etc.
• Best Practices:
  • Don't skip levels (e.g., don't jump from H2 to H4)
  • Make headings descriptive and scannable
  • Use headings to structure content, not for styling
  • Include keywords naturally in headings
  • Headings help users and search engines understand page structure

Content Statistics

• Word Count: Total visible text words on the page
  • Minimum: 250-300 words for most pages
  • Thin content (<250 words) may underperform in search
  • Focus on satisfying user intent, not arbitrary word counts
  • Longer content (1,000-2,000+ words) often ranks better for competitive topics
• Character Count: Total characters in visible text
• Sentence Count: Number of sentences detected
• Paragraph Count: Number of paragraph blocks
• Reading Time: Estimated time to read based on ~200 words/minute
• Text/HTML Ratio: Percentage of text vs. total HTML
  • Low ratios (<15%) may indicate heavy templates or thin content
  • Target: 20-70% depending on page type
  • Add meaningful, user-focused copy to improve ratio

Readability Metrics

• Flesch Reading Ease: Scale of 0-100 (higher = easier)
  • 90-100: Very Easy (5th grade)
  • 80-89: Easy (6th grade)
  • 70-79: Fairly Easy (7th grade)
  • 60-69: Standard (8th-9th grade) — Target for most content
  • 50-59: Fairly Difficult (10th-12th grade)
  • 30-49: Difficult (College level)
  • 0-29: Very Difficult (Professional/Academic)
• Flesch-Kincaid Grade Level: U.S. school grade level needed to understand the text
  • Target: 8-10 for general audiences
  • Adjust based on your audience and topic complexity
  • Technical/academic content may naturally score higher
• SMOG Index: Simple Measure of Gobbledygook; estimates years of education needed
• Coleman-Liau Index: Grade level based on characters per word and words per sentence

SEO Recommendations

Automated suggestions based on detected issues and optimization opportunities:

• Missing or short title/meta tags
• Heading structure problems
• Thin or duplicate content
• Missing security headers
• Non-HTTPS resources (mixed content)
• Missing canonical tags
• Incorrect robots directives
• Performance bottlenecks

Prioritize fixes by impact: Critical issues (indexability, status codes) first, then content/meta, then performance.

Technical SEO

Robots & Indexability

• Robots Meta Tag: Controls indexing (index/noindex) and link following (follow/nofollow)
  • Default: index, follow
  • Use noindex for pages you don't want in search (thank-you pages, admin areas, duplicates)
  • Use nofollow to prevent passing link equity
• X-Robots-Tag: HTTP header alternative to robots meta tag
• robots.txt: Controls crawling (not indexing)
  • Don't block pages you want indexed
  • Use to manage crawl budget and protect sensitive areas
  • Test with Google Search Console
• Indexable: True when status=200 and no noindex directive present

Security Headers

• HSTS (Strict-Transport-Security): Forces HTTPS; add max-age=31536000; includeSubDomains
• CSP (Content-Security-Policy): Mitigates XSS attacks; start with report-only mode
• X-Content-Type-Options: Set to "nosniff" to prevent MIME sniffing
• X-Frame-Options: Prevents clickjacking; set to DENY or SAMEORIGIN
• Referrer-Policy: Controls referrer information; consider "strict-origin-when-cross-origin"
• Permissions-Policy: Restricts browser features (camera, microphone, geolocation)

HTTPS & Mixed Content

• HTTPS: Essential for trust, security, and ranking
• Mixed Content: Loading HTTP resources on HTTPS pages triggers browser warnings
• Fix: Replace all http:// URLs with https:// or use protocol-relative URLs (//)

Social Meta Tags

Open Graph (Facebook, LinkedIn, etc.)

• og:title: Title for social shares (can differ from page title)
• og:description: Description for social previews

Hreflang (Internationalization)

• Purpose: Tells search engines which language/region versions exist
• Format: Use BCP-47 language codes (en, en-GB, en-US, es, fr, de, etc.)
• Implementation:
  • HTML link tags in <head>
  • HTTP headers (for non-HTML content)
  • XML sitemap
• Best Practices:
  • Use reciprocal links (every alternate page must link back)

Frequently Asked Questions

Why isn't my score 100?

The overall score balances multiple factors: title/meta quality, heading structure, content depth, internal links, technical SEO, security headers, and performance. It's a directional signal for optimization opportunities—not a search ranking prediction. Even well-optimized pages may score 70-90 due to subjective factors.

Do meta keywords still matter?

No. Meta keywords tags are ignored by all major search engines (Google, Bing, Yahoo). Focus on title tags, headings, and high-quality content instead.

When should I use "Render JS"?

Enable JavaScript rendering when analyzing SPAs (React, Vue, Angular) or pages where critical content loads via JavaScript. It's slower but ensures you see what search engines and users see after client-side rendering.

How accurate is the PageSpeed analysis?

PageSpeed results come directly from Google's PageSpeed Insights API, which uses real Chrome User Experience Report (CrUX) data when available and Lighthouse lab testing. Results may vary based on location, device, network, and timing.

Can I analyze password-protected pages?

Not currently. The analyzer can only access publicly available pages. For staging sites, consider using HTTP authentication that can be passed in the URL or temporarily allowing access by IP.

Why are some recommendations conflicting?

Some optimizations involve trade-offs. For example, longer content improves depth but may hurt readability scores. Use professional judgment to balance recommendations based on your goals and audience.

How often should I audit my site?

Run audits:

• Monthly for active sites
• After major updates or redesigns
• When launching new content sections
• Before and after technical changes
• When investigating ranking drops

What's the difference between noindex and robots.txt blocking?

robots.txt controls crawling (whether bots can access the page). noindex controls indexing (whether the page can appear in search results). To keep a page out of search results, use noindex and allow crawling. Blocking with robots.txt may prevent search engines from seeing the noindex directive.

Why does my page have duplicate content issues?

Common causes:

• Multiple URLs for the same content (with/without www, http/https, trailing slashes)
• Printer-friendly versions
• URL parameters creating variations
• Syndicated or scraped content
• Product pages with similar descriptions

Solutions: Implement canonical tags, use 301 redirects, consolidate similar pages, or use noindex for duplicates.
