URL debates burn absurd amounts of energy for the third-smallest ranking factor in existence. But a few properties genuinely matter — mostly for humans, slightly for machines — and one mistake costs real equity. Let's settle it in five minutes.
Short and speakable
Good URLs read like a sentence fragment: /blog/crawl-budget-guide. Bad ones read like a database error: /index.php?p=881&cat=12&ref=x9. Speakable URLs get copied, pasted, dictated, trusted in search results, and parsed correctly by every tool ever built. Keep them under roughly five words where possible. Stop words can go; meaning cannot.
Hyphens, lowercase, no dates
Hyphens are the word separator; underscores and spaces cause parsing friction. Lowercase everywhere, because some servers treat /Guide and /guide as two different pages — a duplicate-content trap that costs nothing to avoid. And skip dates in URLs: a /2024/ folder makes every future update look stale, and you can never remove it without breaking links.
The one rule: stability
Every URL change breaks something. External links, bookmarks, crawl history, the anchor text pointing at that address. Changing URLs is sometimes necessary (platform migration, real restructuring) and sometimes pure vanity ("we rebranded the category"). The second category should never win. When a change truly is necessary: one-to-one 301 redirects, old URL to exact new URL, nothing pointing at the homepage, and the redirects kept in place indefinitely — years, not weeks.
What to stop worrying about
Keywords in URLs are a tiebreaker at most — a tiny relevance hint, useful mainly when someone links bare. Subfolders versus subdomains: use folders for content, subdomains only when the platform demands it. And trailing slashes? Pick one, redirect the other, move on. The sites winning your queries are not winning because of their URLs. They're just not losing because of them.
