On-Page SEO Scoring (0-100)

Scrape the target page:

firecrawl scrape {url} --format markdown,links -o .seo/clients/{slug}/content/.firecrawl/page-{slug}.json
firecrawl scrape {url} --html -o .seo/clients/{slug}/content/.firecrawl/page-{slug}.html

Scoring Rubric

How to Check Each

Title tag: Extract <title> from HTML. Count characters. Check keyword position.

Meta description: Extract <meta name="description">. Count characters. Look for action words (discover, learn, get, find, try, start, compare).

H1 tag: Count <h1> occurrences. Should be exactly 1. Check keyword presence.

Heading hierarchy: List all headings in order. Verify H2 follows H1, H3 follows H2. Flag skipped levels (H1 → H3).

Content depth: Count words in main content (exclude nav, footer, sidebar). Compare against top 5 competitors for the same keyword:

firecrawl search "{target-keyword}" --scrape --limit 5 -o .seo/clients/{slug}/content/.firecrawl/competitors-{slug}.json --json

Keyword usage: Count occurrences of primary keyword. Calculate density = (count / total words) * 100. Check if keyword appears in first 100 words. Look for semantic variations and LSI terms.

Internal links: From the links data, count links to same domain. Check anchor text diversity.

Images: Parse all <img> tags. Check alt attribute, src filename, loading attribute, image format.

URL: Analyze URL path. Check length, keyword presence, parameter presence.

Social meta: Check for og: and twitter: meta tags in HTML head.

SERP Preview Generator

Show how the page will appear in Google search results:

┌─────────────────────────────────────────────────┐
│ {title_tag_truncated_at_60_chars}...            │
│ {display_url}                                    │
│ {meta_description_truncated_at_155_chars}...     │
│                                                  │
│ Rich Results: [FAQ ✓] [Review Stars ✗] [Video ✗]│
└─────────────────────────────────────────────────┘

Check:

• Title truncation: will Google cut it off? (> 60 chars or > 580px pixel width)
• Description truncation: > 155 chars gets cut
• URL display: clean and readable?
• Rich result eligibility: based on schema markup present

Content Readability Analysis

Calculate readability metrics from the page content:

• Flesch-Kincaid Grade Level: target 7-9 for most web content

- Formula: 0.39 * (words/sentences) + 11.8 * (syllables/words) - 15.59

• Average sentence length: target 15-20 words
• Paragraph length: target 2-4 sentences per paragraph
• Passive voice usage: flag if > 10% of sentences
• Transition word usage: should appear in 30%+ of sentences

Provide grade: A (grade 6-8), B (grade 9-10), C (grade 11-12), D (grade 13+).

E-E-A-T Analysis

Based on Google's Quality Rater Guidelines, evaluate:

Experience (E1)

• Does the content show first-hand experience?
• Look for: personal anecdotes, original photos, specific details only someone with experience would know
• Score: Strong / Moderate / Weak / Missing

Expertise (E2)

• Does the author demonstrate subject expertise?
• Check for: author byline, credentials, author page, depth of knowledge in content
• Score: Strong / Moderate / Weak / Missing

Authoritativeness (A)

• Is this source/author recognized as an authority?
• Check for: brand mentions in other sources, citations, industry recognition, domain age
• Score: Strong / Moderate / Weak / Missing

Trustworthiness (T)

• Can users trust this content and site?
• Check for: HTTPS, contact information, privacy policy, terms of service, sources cited in content, factual accuracy indicators
• Score: Strong / Moderate / Weak / Missing

E-E-A-T recommendations should be specific: "Add author bio with credentials" not "improve E-E-A-T."

Featured Snippet Optimization

Analyze target keyword for featured snippet opportunity:

firecrawl search "{keyword}" --scrape --limit 3 -o .seo/clients/{slug}/content/.firecrawl/snippet-{slug}.json --json

Snippet types and how to win them:

Optimization steps:

1. Check if a featured snippet currently exists for the target keyword
2. Identify the snippet type (paragraph, list, table)
3. Recommend content format changes to match
4. Provide a draft snippet-optimized content block

Content Gap Analysis

Compare client content against top competitors for a topic cluster:

# Scrape competitor content for the same topic
firecrawl search "{topic} site:{competitor-domain}" --scrape --limit 10 -o .seo/clients/{slug}/content/.firecrawl/comp-gap-{slug}.json --json

Identify:

• Subtopics competitors cover that client does not
• Content formats competitors use (video, infographic, interactive, calculator)
• Questions competitors answer that client doesn't address
• Depth differences (word count, number of examples, data points)

Output as prioritized content brief suggestions.

Content Decay Detection

Identify content that needs refreshing:

Decay signals (check for each published page):

1. Outdated statistics: years mentioned in content that are 2+ years old
2. Broken external links: links to pages that now 404
3. Stale references: mentions of deprecated tools, old versions, discontinued products
4. Competitor improvement: competitors have published newer, more comprehensive content on the same topic
5. Thin content: pages with < 500 words that once ranked but may have been surpassed
6. Missing current year: "best X" or "guide to X" content without current year reference

Detection method:

1. Scrape the page content with firecrawl
2. Look for year mentions older than 2024
3. Check for "updated" or "published" dates > 12 months old
4. Compare word count against current top 5 for the same keyword
5. Check if competitors have fresher content via search dates

Output:

{
  "url": "/blog/old-post",
  "title": "Page Title",
  "decay_signals": ["outdated_statistics", "thin_content"],
  "published_date": "2023-06-15",
  "word_count": 450,
  "competitor_avg_word_count": 1800,
  "refresh_priority": "high",
  "recommended_actions": ["Update statistics to 2026", "Expand content to 1500+ words", "Add FAQ section"]
}
