Should I use hyphens or underscores in URL slugs?

Use hyphens. Google treats hyphens as word separators so free-seo-audit is read as three separate words. Underscores are treated as connectors so free_seo_audit is read as one word. Hyphens improve both readability and keyword recognition in search results.

How long should a URL slug be?

Keep URL slugs under 60 characters. Shorter slugs rank slightly better because they signal topic focus. A slug between 20 and 50 characters is ideal. Avoid stop words like the, a, and, of unless they are part of a proper name or branded term.

Should I include keywords in my URL slug?

Yes. The URL slug is a confirmed ranking signal. Include your primary keyword and remove filler words. If your page title is How to Build a Revenue Infrastructure System in 90 Days the ideal slug would be revenue-infrastructure-system or build-revenue-infrastructure. Match the slug to the primary keyword your page targets.

Can I change a URL slug after a page is live?

Yes but always set up a 301 redirect from the old URL to the new one. Changing a URL without a redirect loses all the link equity and ranking signals the original page has built. If the page has significant backlinks or organic traffic, changing the slug is a risk that needs to be weighed carefully against the SEO benefit.

What characters should I avoid in URL slugs?

Avoid spaces, special characters like exclamation marks and asterisks, uppercase letters, and multiple consecutive hyphens. Some CMS platforms automatically handle these but relying on clean input is safer. Numbers are acceptable when they add meaning such as a year or a numbered list.

Understanding your score

What your slug length means

Slug length directly affects how Google and users perceive your page topic. Shorter slugs signal focus.

20 to 50 characters

Ideal

Clean, focused, keyword-rich. Google reads it as a clear signal. Users trust short URLs and share them without truncation.

51 to 75 characters

Acceptable

Still functional but starting to dilute keyword density. Some platforms truncate at 75 characters. Consider trimming stop words.

76 characters or more

Too long

Slugs over 75 characters get truncated in previews, share cards, and some CMS platforms. Google will still index it but ranking efficiency drops.

Alokk's perspective

Alokk Founder and Lead Growth Architect, Groew

After auditing over 200 B2B sites, the same slug mistakes repeat: full page titles pasted in as-is, underscores instead of hyphens, dates baked into slugs that age the content permanently. One client had 40 product pages with URLs over 120 characters. After a slug cleanup and 301 redirects to cleaner versions, average click-through rate from Google Search improved 18 percent within 60 days. The URL is the first signal Google reads before it even opens your page.

The complete guide to SEO-friendly URL slugs

URL structure is one of the oldest and most consistently confirmed ranking signals in Google's algorithm. Most businesses get it wrong in the same three ways. Here is how to get it right.

Why URL slugs are a ranking signal

Google reads the URL before it reads anything on your page. The slug is the first topical signal Google sees. When your slug contains your primary keyword, you get a relevance signal at every crawl, every click, and every backlink anchor that includes the URL. In a 2023 study of 1.4 million Google first-page results, pages with keyword-matching slugs had a 15 percent higher average click-through rate than those without. The mechanism is simple: users scan URLs before clicking. A clear slug builds trust instantly.

Read the complete guide

The three most common slug mistakes

The first mistake is copying the full page title into the slug without editing. Page titles often contain stop words, dates, and phrases that reduce keyword density when placed in a URL. The slug version of a title should be a distilled keyword target, not a copy-paste. The second mistake is using underscores instead of hyphens. Google's official guidance has favoured hyphens since 2009 and that has not changed. The third mistake is baking a year or date into a slug. A slug like best-seo-tools-2024 becomes stale in January 2025 and either needs a redirect or starts signalling old content.

How to structure slugs for topical authority

If you are building topical authority in a category, your slugs should follow a consistent hierarchy. A pillar page slug might be /seo-for-b2b-companies and supporting articles under it would be /seo-for-b2b-companies/keyword-research or /b2b-seo-keyword-research depending on your URL architecture. Consistent slug structure signals to Google that these pages form a cluster. Groew builds this into every organic search infrastructure sprint from day one. Topical clusters with coherent slug hierarchies rank faster than isolated pages with identical domain authority.

Stop words: when to keep them, when to remove them

Stop words are common words like the, a, an, of, and, for, in, to, with. In most cases removing them from slugs tightens keyword density without losing meaning. best-seo-tools is stronger than the-best-seo-tools-for-businesses. However there are cases where stop words should stay. Brand names that include stop words, phrases where removal changes meaning, and terms where the full phrase is the exact search query are exceptions. This generator's stop words toggle gives you both versions to compare before choosing.

Changing slugs on live pages safely

When you change a slug on a page that already has backlinks, organic traffic, or Google indexing, you must set up a 301 permanent redirect from the old URL to the new one immediately. A 301 passes approximately 90 to 99 percent of link equity to the new URL. Without the redirect, every link pointing to the old URL becomes a dead end and all accumulated authority is lost. Use Google Search Console to monitor crawl errors after any slug change and verify the redirect is working within 24 hours. For pages with significant traffic, wait at least 6 months before changing a slug unless there is a strong SEO reason to do so sooner.

URL slugs and the Revenue Infrastructure model

Clean slug architecture is not a one-time task. It is an ongoing infrastructure decision. Every page you publish is a permanent asset in your Digital Landlord model. A well-structured slug hierarchy makes your site easier to crawl, easier to link internally with keyword-rich anchors, and easier for AI systems to understand as topical authority. Groew treats URL architecture as part of the first 30 days of every organic search infrastructure engagement because the compounding value of getting it right from the start outweighs the cost of fixing it later.
