The 2026 SEO Checklist (Every Page, Every Site)

How to Use This Checklist

Bookmark this page. Fork it into Notion, Linear, or Google Docs and turn it into a template your team runs before every publish. The order below is intentional — do the pre-publish section on every new page, the quarterly section every 3 months, and the refresh section on any post that's sliding after 12+ months.

Pre-Publish Checklist (Every New Page)

Run this in order. Skip nothing.

1. Primary keyword chosen, real monthly search volume confirmed.

3. Title tag under 60 characters, keyword front, CTR hook present.
4. Meta description under 155 characters, benefit-driven.
5. One H1, close to but not identical to title.
6. H2 outline covers every subtopic ranking in the top 3.
7. URL slug: 3–5 words, lowercase, hyphenated, keyword included.
8. First paragraph answers the query in one sentence.
9. Key takeaways block near the top.
10. TOC on any article over 1,500 words.

16. FAQPage schema present if a real FAQ exists.
17. Author byline linking to author page.
18. Publish date set; last-modified date populated.

• Entity signals: author, brand, product mentioned by name, linked to authority pages.
• sameAs on author schema linking to LinkedIn, X, GitHub, Wikipedia if applicable.
• Server-rendered HTML — GPTBot/ClaudeBot/PerplexityBot struggle with SPAs.
• llms.txt file at site root describing your content and licensing preferences (optional but emerging standard).

Quarterly Site-Wide Audit

1. Full Screaming Frog / Sitebulb crawl — export issues, prioritize by impact.
2. Search Console: coverage errors, CWV regressions, manual actions.
3. Server log sample: are bots crawling your money pages? Any waste?
4. Backlink audit: any new toxic links to disavow? Any lost high-quality links to reclaim?
5. Top 20 pages by traffic: still ranking? Anything sliding needs refresh?
6. Cannibalization check: multiple URLs ranking for the same query? Consolidate.
7. Orphan page report: every important URL has inbound internal links?
8. Schema validation across templates — nothing silently broke.
9. Competitor gap analysis: keywords they rank for that you don't.
10. AI-search visibility check (Peec.ai, Otterly.ai) — where are you getting cited?

Content Refresh Checklist

For any post 12+ months old with declining traffic:

• Rewrite title tag — refresh year, sharpen CTR angle.
• Update meta description.
• Update datePublished only if content is substantially rewritten; always update dateModified.
• Refresh outdated stats to current year, cite new sources.
• Add sections covering recent SERP shifts / People Also Ask changes.
• Expand any thin H2s uncovered by SEO tools.
• Add 3–5 new internal links from newer articles.
• Add or expand FAQ block using current PAA queries.
• Re-validate schema after edits.
• Request re-indexing in Search Console.
