Onpage SEO

On-Page SEO Audit — Phase 3

Executive Summary

On-page SEO is the highest-leverage, lowest-cost ranking lever available. Title tag + meta optimization alone can improve CTR by 20–35% within 30 days (GSC data 2024). In 2025, on-page signals have a dual role: traditional ranking AND AI Overview citation probability. Pages without direct standalone answers and FAQPage schema rarely appear in AIO. Always compare against the top-ranking competitor's on-page patterns.

Tools for This Phase

Step 1: Read Project Context

Read {AUDIT_DIR}/intake-data.md — business name, URL, services, location. Read {AUDIT_DIR}/technical-findings.md — page indexation status, canonical issues. Read {AUDIT_DIR}/competitor-profiles.md — competitor on-page patterns, title formats, schema usage. Read {DATA_DIR}/crawl/ — crawler output for bulk title/meta analysis.

Priority Page Inventory

Audit in this order (highest business impact first):

1. Homepage
2. Primary service page(s) — one per core service
3. Location/service-area pages
4. Top-performing blog posts (by GSC impressions — filter top 10)
5. Contact page
6. About page (E-E-A-T critical)

Section 1: Title Tags

Character Limits (2025)

• Optimal: 50–60 characters (displays fully in desktop SERPs)
• Mobile SERP: 50–55 characters
• Maximum before truncation: 60 characters (580px pixel width)
• Google rewrites if: Title doesn't match page content or is < 10 characters

Per-Page Checklist

For each key page, verify:

• Unique across the entire site? (Screaming Frog → Title → duplicates)
• Primary keyword in first 5 words?
• 50–60 characters?
• Location included for all service/location pages?
• Brand name at end (after | or —)?
• Contains action word, number, or value prop for CTR?
• No keyword stuffing (same keyword repeated)?

Optimal title formats:

AI Overviews Title Optimization

Titles that appear in AIO tend to:

• Directly match conversational query intent
• Include "How", "What", "Best", or specific quantifiers
• Signal definitive authority: "Complete Guide", "Expert Guide", "[Year] Guide"

Competitor Title Comparison

Section 2: Meta Descriptions

Character limits: 150–160 characters (desktop) | 130–145 characters (mobile) If Google rewrites 90%+ of meta descriptions: Page content doesn't match intent — rewrite lead paragraph first.

Per-page checklist:

• Unique across site? (Screaming Frog → Meta Description → duplicates)
• 150–160 characters?
• Contains primary keyword + location (local pages)?
• Clear value proposition (WHY click this result)?
• CTA: "Call today", "Get a free quote", "Book online"?
• Phone number on high-conversion service pages?
• No passive language ("We provide..." → "Get same-day service...")?

Section 3: Header Tag Hierarchy (H1–H6)

Per-page checks:

• Exactly ONE H1 per page? (Screaming Frog → H1 → filter "Multiple H1")
• H1 contains primary keyword?
• H1 is unique across the site?
• Logical hierarchy — no level skipping (H1 → H2 → H3, NOT H1 → H3)?
• H2s structure main sections with secondary keywords?
• H3s for subtopics under H2s?
• Headers descriptive, not generic ("Our Services" → "Plumbing Services in Chicago")?
• Question-format H2s/H3s for AIO citation potential?

AIO-optimized header pattern (2025):

H1: [Primary Keyword in City] — [Benefit]
  H2: What Is [Service]?  ← AIO extraction target
  H2: How Much Does [Service] Cost in [City]?  ← AIO + featured snippet
    H3: Factors Affecting [Service] Cost
  H2: Our [Service] Process  ← HowTo schema opportunity
  H2: Frequently Asked Questions  ← FAQPage schema target
    H3: [Question 1]?
    H3: [Question 2]?

• Primary keyword in first 100 words: ✅/❌

Section 7: Image SEO

Section 8: AI Overviews Optimization (2025 Critical)

Pages cited in AIO score 4× the impressions of position 1 organic when AIO appears. AIO appears for 20–35% of local service queries (SparkToro 2025).

AIO citation requirements — checklist per page:

• Direct, standalone answer in first 40–50 words (no preamble)?
• Question-format H2/H3 headers matching common voice/conversational queries?
• Definitions: "A [service] is..." format in first paragraph?
• Specific data points (costs, timelines, measurements) stated precisely?
• Numbered step-by-step processes (HowTo schema opportunity)?
• Structured comparisons using tables?
• FAQPage schema with 5+ questions on service pages?
• Content updated within last 30 days (freshness = AIO citation bias)?
• Business rated ≥ 4.3 stars (review signal for local AIO)?

Test: Search target keyword → does AIO appear? Is client cited? If competitor cited but not client → content gap in answer structure.

Section 9: Page Experience Signals

• Core Web Vitals all "Good" (from Phase 10)? ✅/❌
• No intrusive interstitials blocking content on mobile? ✅/❌
• No aggressive ads above fold? ✅/❌

On-Page SEO Priority Action Table

Issue Priority by Type

Numbered Action Plan

Immediate (Week 1, No Dev Required)

1. Add FAQPage schema to all service pages — highest ROI action: 3.2× AIO citation rate, 30 min/page, no developer needed via JSON-LD script block. Effort: 30 min/page. Priority: 25.
2. Fix title tags — ensure primary keyword in first 50 characters; title length 50–60 characters; unique per page. Use Screaming Frog to batch-identify. Effort: 5 min/page. Priority: 20.
3. Fix duplicate or missing H1s — each page must have exactly one H1. Check with Screaming Frog → filter "Missing H1" and "Multiple H1". Effort: 5 min/page. Priority: 20.
4. Optimize meta descriptions — 120–155 characters, includes primary keyword, has a CTA ("Call us today", "Get a free quote"). Missing meta = Google auto-generates (usually suboptimal). Effort: 5 min/page. Priority: 15.
5. Fix orphaned pages — run site_crawler.py → identify pages with <3 inbound internal links → add contextual links from related pages (not navigation). Effort: 15 min/page. Priority: 20.

Short-Term (Week 2–4, Content + Developer)

6. Add HowTo schema to process pages — "How to [service]" pages without HowTo schema miss featured snippet + AIO opportunities. Effort: 30 min/page. Priority: 16.
7. Expand thin content — service pages <800 words: expand with: local pricing context, process steps, FAQs, local testimonials, before/after. Target Surfer Score ≥70. Effort: 2–4 hrs/page. Priority: 15.
8. Resolve keyword cannibalization — 2+ pages targeting same keyword: pick the stronger one (more links, better CTR), 301 redirect the weaker, consolidate content. Effort: 1–2 hrs per pair. Priority: 16.
9. Add bulk image alt text — use Screaming Frog to export all images missing alt text → add descriptive alt text (keyword-included where relevant, descriptive always). Effort: 30 min bulk. Priority: 15.
10. Audit and fix duplicate title tags — Screaming Frog → filter Duplicate Title Tags → rewrite each to be unique and keyword-specific. Effort: 5 min/page. Priority: 20.
