The 'ideal blog post length' question has dominated SEO discourse for a decade, mostly producing wrong answers. The honest answer in 2026: length should match search intent. The user typing 'what is canonical tag' wants a clear definition and examples — probably 1,200–1,800 words. The user typing 'complete guide to canonical tags' wants comprehensive coverage — 3,000+ words. The user typing 'plumber Westboro' wants a phone number and hours — 600 words is plenty. The actual ranking patterns we observe across Canadian client engagements: informational queries with high competition (definitions, how-tos, ultimate guides) reward content depth — top-ranking pages typically span 1,500–4,000 words because that's how much content the topic genuinely requires for comprehensive coverage. Padding does not help; comprehensive coverage does. Commercial-intent pages (service pages, product pages, location pages) perform best at moderate length: 800–1,500 words. Enough to demonstrate expertise and address buyer questions, not so much that conversion paths get buried. Most Canadian SMB service pages we audit are too short (300–500 words) and lose to competitors with proper depth. Comparison and listicle pages need depth proportional to the comparison: a '5 best CRMs' post can work at 2,500 words; a '50 best CRMs' post needs 8,000–12,000 words to provide useful detail per option. Don't write 'top 50' lists if you can't sustain that depth; the format becomes unreadable padding. Programmatic SEO pages (location-service combinations, glossary entries, near-me pages) can succeed at 600–1,500 words if each page provides genuinely unique value for its specific intent — local context, location-specific examples, definition-specific clarity. The trap is producing thin near-duplicate pages at scale; Google's helpful content updates have systematically suppressed those patterns. The metric that matters more than length: comprehensiveness relative to top-ranking competitors. Pull the top 10 ranking pages for your target query, identify the topics, subtopics, examples, and structures they collectively cover, and ensure your piece covers the full intersection plus 10–20% of additional unique value. This 'comprehensiveness audit' produces better results than any word-count target.
