Run The SEO Review

Work through the 60-point SEO checklist and capture gaps in crawlability, metadata, content, and authority.

Core Web Vitals (Google's official page experience metrics) 4 checks

1. Largest Contentful Paint (LCP) is under 2.5 seconds.

LCP measures loading performance — specifically when the largest visible content element finishes rendering. Google threshold: ≤2.5s is "good," 2.5-4.0s is "needs improvement," >4.0s is "poor." Test with Google PageSpeed Insights or Chrome Lighthouse. Priority: Critical

2. Interaction to Next Paint (INP) is under 200 milliseconds.

INP measures responsiveness — how quickly the page responds to user input. Google threshold: ≤200ms is "good," 200-500ms is "needs improvement," >500ms is "poor." INP replaced FID (First Input Delay) in March 2024. Priority: Critical

3. Cumulative Layout Shift (CLS) is under 0.1.

CLS measures visual stability — whether page elements shift unexpectedly during load. Google threshold: ≤0.1 is "good," 0.1-0.25 is "needs improvement," >0.25 is "poor." Common causes: images without width/height attributes, late-loading ads or banners, dynamic content insertion. Priority: Critical

4. Core Web Vitals pass for 75% of page visits.

Google's thresholds must be met for at least 75% of real-user visits (measured via field data from Chrome User Experience Report). Lab data from Lighthouse is useful for debugging but not used for ranking. Check Search Console → Core Web Vitals report. Priority: Critical

Crawlability & Indexation 6 checks

5. Site uses HTTPS (not HTTP).

Google has confirmed HTTPS as a ranking factor since 2014. Sites on HTTP show "Not Secure" warnings in browsers, creating trust and ranking penalties. Install an SSL certificate (free via Let's Encrypt). Priority: Critical

6. XML sitemap is submitted and healthy.

Sitemap lists all pages you want indexed. Submit via Google Search Console → Sitemaps. Check for errors. Sitemap should include only canonical, indexable URLs. Priority: Critical

7. robots.txt is configured correctly.

robots.txt tells crawlers which pages they can access. Common mistakes: blocking important pages, blocking JavaScript/CSS, using wildcards incorrectly. Also ensure you're not blocking AI crawlers (GPTBot, ClaudeBot, PerplexityBot) if you want AI discoverability. Priority: Critical

8. No pages are accidentally noindexed.

<meta name="robots" content="noindex"> removes pages from Google's index. Check every important page for accidental noindex tags. Use Screaming Frog to audit all pages. Priority: Critical

9. Canonical tags are correct.

Every page has a self-referencing canonical tag or points to the correct primary version. Prevents duplicate content issues. Mismatched canonicals confuse Google. Priority: Major

10. No orphan pages.

Every indexable page is linked from at least one other page on your site. Orphan pages are hard to crawl and rarely rank. Audit with Screaming Frog. Priority: Major

Mobile-First Indexing 3 checks

11. Mobile version is fully functional.

Google uses the mobile version of your site for ranking (mobile-first indexing). Mobile site must have the same content, metadata, and structured data as desktop. Priority: Critical

12. Mobile usability has no errors.

Check Google Search Console → Mobile Usability. Common errors: touch elements too close, text too small, viewport not configured, content wider than screen. Priority: Critical

13. Mobile page speed meets Core Web Vitals.

Mobile is typically slower than desktop due to network and device constraints. Mobile Core Web Vitals are more important than desktop for rankings. Priority: Critical

Site Architecture 4 checks

14. Site structure is logical (3-click rule).

Users and crawlers can reach any important page within 3 clicks from the homepage. Deep URLs (/blog/category/subcategory/subsubcategory/post) reduce crawlability. Priority: Major

15. URLs are clean and descriptive.

Use hyphens (not underscores). Use lowercase. Include target keyword. Keep under 75 characters. Avoid parameters (?id=123) for important pages. Priority: Major

16. Internal linking strategy is in place.

Pages link to related pages with descriptive anchor text. Important pages have more internal links pointing to them. Avoid links like "click here" — use descriptive text. Priority: Major

17. No broken internal links (404s).

Test with Screaming Frog or Broken Link Checker. Fix or redirect broken links. Broken links waste crawl budget and hurt user experience. Priority: Major

Structured Data 3 checks

18. Organization schema is implemented.

Add JSON-LD schema for Organization on homepage with name, logo, URL, contact info, social profiles. Helps Google understand who you are. Priority: Major

19. Relevant schema types are added per page.

Article schema for blog posts, FAQPage for FAQ pages, Product for product pages, BreadcrumbList for breadcrumbs, SoftwareApplication for SaaS products. Priority: Major

20. Schema validates with no errors.

Test with Google Rich Results Test (search.google.com/test/rich-results) and Schema.org validator. Errors prevent rich snippets. Priority: Major

Title Tags 3 checks

21. Every page has a unique title tag.

No duplicate titles across pages. Use Screaming Frog to find duplicates. Priority: Critical

22. Titles are 50-60 characters.

Longer titles get truncated in search results. Include primary keyword near the beginning. Format: Primary Keyword | Brand or Primary Keyword - Secondary Context | Brand. Priority: Major

23. Titles match search intent.

If users searching your keyword want a "how-to" guide, your title should indicate that. If they want a comparison, structure accordingly. Priority: Major

Meta Descriptions 2 checks

24. Every page has a unique meta description.

Under 155-160 characters. Describes what's on the page. Includes the target keyword naturally. Encourages clicks with benefit-focused language. Priority: Major

25. Meta descriptions include a clear value proposition.

Why should someone click? What will they learn, get, or accomplish? Generic descriptions ("Welcome to our blog") waste the opportunity. Priority: Major

Heading Structure 3 checks

26. One H1 per page.

The H1 should contain your primary keyword. Multiple H1s confuse Google about the page's main topic. Priority: Major

27. Headings follow logical hierarchy.

H1 → H2s for sections → H3s for subsections. Don't skip levels (no H1 → H3 without H2). Priority: Major

28. Headings contain target keywords (naturally).

Include primary keyword in H1 and at least one H2. Use related keywords (LSI) in other H2s and H3s. Avoid keyword stuffing. Priority: Major

Content Optimization 3 checks

29. Primary keyword appears in the first 100 words.

Signals to Google what the page is about. Natural usage, not forced. Priority: Major

30. Content length matches search intent.

"What is X?" queries: 800-1,500 words. "How to X" queries: 1,500-2,500 words. Comprehensive guides: 2,500-5,000 words. Quick answers: 300-600 words. Length should match intent, not exceed it. Priority: Major

31. Content is written for humans first.

Avoid keyword stuffing (keyword density over 2-3% is a red flag). Write naturally, then optimize. Use synonyms and related terms. Priority: Major

Images 3 checks

32. All images have descriptive alt text.

Alt text should describe the image content. Use target keyword naturally where relevant, but don't force it. Decorative images have empty alt="". Priority: Major

33. Images are compressed and optimized.

Use WebP format for best compression. Aim for under 200KB per image. Use responsive srcset for different screen sizes. Large images slow down LCP. Priority: Major

34. Images have width and height attributes.

Prevents Cumulative Layout Shift (CLS) during load. Tell the browser the space the image will occupy before it loads. Priority: Major

Links 1 checks

35. Internal links use descriptive anchor text.

"Read our SaaS onboarding guide" (not "click here"). Anchor text helps Google understand what the linked page is about. Priority: Major

Keyword Research 3 checks

36. Primary keywords are researched and targeted.

Use Ahrefs, SEMrush, or Google Keyword Planner. Target keywords with: clear search intent, reasonable volume (100+ searches/month), achievable difficulty for your domain authority. Priority: Critical

37. Keywords are mapped to specific pages.

Each page targets one primary keyword + 2-3 related secondary keywords. Avoid targeting the same keyword with multiple pages (keyword cannibalization). Priority: Major

38. Long-tail keywords are captured.

Beyond primary keywords, target long-tail variations that match user questions. Long-tail keywords have lower volume but higher conversion rates. Priority: Major

Topic Clusters & Content Architecture 3 checks

39. Pillar pages exist for core topics.

Comprehensive pillar pages (2,000-5,000 words) cover major topics. These rank for competitive keywords and anchor topic clusters. Priority: Major

40. Cluster pages link to pillar pages.

Supporting articles target long-tail variations and link back to the pillar page. Pillar links out to cluster pages. Creates topical authority. Priority: Major

41. Content calendar aligns with keyword strategy.

Publishing schedule targets keyword opportunities systematically, not randomly. See Resource 11: Content Marketing Calendar Template. Priority: Major

Content Quality (E-E-A-T) 4 checks

42. Content demonstrates Experience.

Firsthand knowledge, real examples, case studies, original data. Google's E-E-A-T prioritizes experiential content. Priority: Major

43. Content demonstrates Expertise.

Author credentials visible. Content written by subject matter experts. Technical accuracy. Priority: Major

44. Content demonstrates Authoritativeness.

Your brand is cited by others, mentioned in industry publications, linked from authoritative sources. Priority: Major

45. Content demonstrates Trustworthiness.

Accurate information, cited sources, contact information, privacy policy, transparent business practices. Priority: Major

Freshness & Maintenance 2 checks

46. Content is regularly updated.

Outdated content loses rankings. Review top-performing pages every 6-12 months. Update statistics, examples, and links. Priority: Major

47. Low-performing content is pruned or merged.

Pages with no traffic, thin content, or outdated information drag down overall site authority. Either improve, merge, or remove (with redirects). Priority: Minor

Search Intent Matching 3 checks

48. Content matches the SERP format.

If top results are list posts, don't publish a long essay. If top results are guides, don't publish a quick answer. Analyze the current top 10 before writing. Priority: Major

49. Featured snippets are optimized for.

Structure content with clear headings, concise answers (40-60 words), numbered lists, and tables for question-based queries. Priority: Major

50. Content covers questions users ask.

Use AnswerThePublic, AlsoAsked, or the "People Also Ask" section of search results to identify related questions. Address them in your content. Priority: Major

Backlink Strategy 4 checks

51. Domain Authority / Domain Rating is tracked.

Monitor with Ahrefs, Moz, or SEMrush. Baseline your current authority and track over time. Priority: Major

52. Quality of backlinks matters more than quantity.

One link from TechCrunch is worth 100 from low-quality directories. Focus on earning links from relevant, authoritative sites. Priority: Major

53. Backlink acquisition strategy is in place.

Guest posting, digital PR, original research, tool creation, broken link building, resource page outreach, HARO/Qwoted, podcast appearances. Priority: Major

54. Toxic backlinks are monitored and disavowed.

Spammy links from irrelevant sites can hurt rankings. Use Google Search Console to identify and disavow via Disavow Tool. Priority: Major

Brand Signals 2 checks

55. Brand is searched for.

Branded search volume is a strong ranking signal. Growing branded searches over time indicates growing authority. Priority: Major

56. Brand is mentioned across the web (even unlinked).

Unlinked brand mentions are increasingly important. Use tools like Google Alerts or Mention.com to monitor. Priority: Minor

Local SEO (if applicable) 2 checks

57. Google Business Profile is optimized.

Complete profile, accurate NAP (Name, Address, Phone), categories, photos, posts, reviews. Priority: Major (for local businesses)

58. NAP consistency across web.

Name, Address, Phone number consistent everywhere (your site, directories, social profiles, citations). Priority: Major (for local businesses)

Reviews & Reputation 2 checks

59. Reviews are collected and managed.

Google reviews, G2, Capterra, Trustpilot (whatever is relevant). Respond to both positive and negative reviews. Priority: Major
