Getting title, meta description, and canonical right

title, meta description, and canonical URL show up in every SEO checklist. If you're setting them "by vibes," this post walks through what each one actually does and the mistakes that keep biting teams in production.

title tag

The page's "name" as shown in search results, social cards, and the browser tab. Google uses it as a ranking signal with high confidence — one per page, accurately descriptive, roughly 50–60 characters.

Common mistakes

• Every page gets the same "Site Name | Home"
• Keyword-stuffed, not natural English
• Too long to display in SERP
• CMS default title leaking because dynamic generation is broken

meta description

Shown as the snippet in search results. Direct ranking impact is weak, but CTR impact is strong. If you leave it blank Google picks a paragraph from the body — almost always the wrong one.

What good looks like

• 120–160 characters
• Summary of the page plus one benefit or CTA
• Don't reuse the same description across pages
• Natural sentences, not keyword lists

canonical URL

Tells search engines "this is the official URL for this content." Use it to collapse ranking signals when the same content lives under multiple URLs (query strings, AMP, www vs non-www, trailing slash variants).

Patterns to verify

• Set a self-referential canonical on every page — safest default
• For query strings that don't change the content, canonicalise to the clean URL
• Pagination (?page=2) should self-canonicalise, not point to page 1
• Never combine canonical with noindex — the signals contradict each other

Implementation traps

• Dynamic title generation is broken; every page ends up with the same title
• Canonical always points at / — typical SPA default
• meta description left empty in production
• 404 page missing a proper "Page not found" title
• Trailing slash inconsistency across the site

Auditing everything at once

Opening pages in the browser one by one works up to about 10 pages. For full-site audits, crawl tools list every page's title / meta / canonical / noindex in one table — much faster.
