Keywords in URLs vs Titles: What Matters for SEO

What Google's own documentation says about keywords in URLs and in title elements, how much each one affects rankings and clicks, when changing a URL is worth the risk, and a slug and title pattern you can standardize across a site.

Do Keywords in URLs Help SEO?

A little, and less than most people assume. Google’s guidance on URL structure is about readability, not keywords. Its URL structure documentation asks for “readable words rather than long ID numbers,” words in your audience’s language, and hyphens between words. It never describes keywords in a slug as a ranking lever. The SEO Starter Guide goes further and lists “Keywords in the domain name or URL path” under things you shouldn’t focus on.

Google’s John Mueller has said the same thing for years. In a January 2016 hangout he called URL keywords “a very small ranking factor” and said it wasn’t worth restructuring a site just to get keywords into URLs, as Search Engine Roundtable reported. In a March 2021 office-hours session he described words in a URL as a very lightweight factor that matters mostly before Google has seen the page’s content.

Where URL words still pay off

The value of URL words is mostly for people:

• Breadcrumbs on desktop. Google builds the breadcrumbs under the site name from words in the URL, or from BreadcrumbList structured data. Since January 2025, mobile results show only the domain, so on phones the slug is not visible in search at all.
• Shared links. A link like /guides/running-shoes-flat-feet tells someone in Slack or an email what they’ll get. /p?id=4832 doesn’t.
• Clicks, maybe. In Backlinko’s study of 4 million Google results, URLs containing a term similar to the keyword had a 45% higher click-through rate than URLs without one. That is a 2019 correlation, not proof that the URL caused the clicks.

So a descriptive slug is a good default for new pages. It just isn’t worth breaking a working URL for.

What Google Says About Keywords in Title Tags

The title tag matters far more, because it usually becomes the title link: the large clickable headline in the result. Google’s title link documentation lists where that headline can come from. Your <title> element comes first, followed by the main visible title, H1 and other headings, og:title, other prominent text, anchor text on the page and in links pointing to it, and WebSite structured data. For how that headline fits alongside snippets and other features on the page, see how Google builds title links and SERP features.

The writing guidance is short:

• Give every page a descriptive, concise title. Avoid vague labels like “Home” or “Profile.”
• Don’t repeat words. Google’s example of what not to do is “Foobar, foo bar, foobars, foo bars”. It calls that keyword stuffing and says it can make results look spammy.
• Make each page’s title distinct, and add your site name once, at the start or end.
• There is no length limit, but Google truncates the title link to fit the device width.

A keyword in the title seems to be the minimum, not the thing that separates the top results. Backlinko’s analysis of 11.8 million results found that most first-page titles contain all or part of the keyword they rank for. It also found “essentially zero correlation” between having the keyword in the title and ranking higher within page one. Use the keyword so the page clearly matches the query. After that, the title’s job is to earn the click.

Why Google rewrites title tags

Google doesn’t always show your <title>. In September 2021 it said title elements were used about 87% of the time, up from about 80% after its August 2021 change. Since that August 2021 update, titles generally no longer change based on the query.

The title link documentation names the usual triggers: half-empty titles, obsolete titles (an old year in the title, a new one on the page), inaccurate titles, micro-boilerplate repeated across pages, no clear main heading, a language mismatch, and a duplicated site name. Zyppy’s study of 80,959 titles across 2,370 sites (early 2022, desktop) counted any change, including small ones, and found 61.6% of titles were rewritten. Titles over 70 characters were rewritten 99.9% of the time. The lowest rewrite rates were between 51 and 60 characters, and repeating the same keyword was one of the triggers.

The fix Google suggests is a title that matches your most prominent heading. Putting the title text in the first visible H1 is one way. If your listing shows text you didn’t write, the guide to results-page issues that cut organic CTR walks through diagnosing it.

Keywords in URLs vs Titles: Side-by-Side

In short, the title does the ranking-relevance and click work. The URL is an identifier, so it should be readable and it should not change.

Before and After: Slug and Title Examples

Most fixes below come straight from Google’s documentation; the one that doesn’t is marked as a house rule.

A Slug and Title Pattern to Standardize

Writing the rules down once saves debating every new page. Here is a pattern that follows Google’s guidance. Limits marked as house rules are editorial conventions, not Google requirements.

Slugs

1. Use the page’s main topic in plain words, lowercase, separated by hyphens.
2. Keep it to roughly 3–5 words (a house rule). Google sets no URL length limit. Backlinko’s ranking study found position-1 URLs were on average 9.2 characters shorter than position-10 URLs, a slight correlation.
3. Leave out anything that will go out of date: years, list counts (“11-ways”), prices, version numbers.
4. Add folders only when they reflect real site sections, such as /guides/ or /docs/.
5. Google’s docs say nothing about stop words. Drop them when the slug stays clear without them, and keep them when they carry meaning (“how-to”).

Titles

1. State the page’s topic in the words searchers use, with the main term early, since truncation cuts from the end.
2. Aim for about 50–60 characters (a house rule supported by Zyppy’s 51–60 sweet spot), then check what stays visible rather than counting exactly.
3. Make the title and the H1 say the same thing. They don’t have to match word for word.
4. Add the brand once, at the start or end, with a delimiter. Zyppy found dashes were removed or replaced 19.7% of the time, pipes 41%.
5. Make sure no other page on the site uses the same title.

Two free tools help. Skribra’s slug and URL optimizer lowercases a title, strips special characters and joins words with hyphens. It flags slugs over 60 characters or 5 words. It keeps only a–z, 0–9 and hyphens, so for non-English slugs follow Google’s advice on using your audience’s language and percent-encoding instead. The SERP preview tool shows a title and description as a result and flags titles over 60 characters and descriptions over 160. Google truncates by display width, not character count, so treat the preview as a close estimate. For the rest of the page, a manual on-page audit covers headings, snippets and links.

When to Change a URL (Almost Never)

A missing keyword is not a good reason to change a URL. These are:

• The URL is made of IDs, session tokens or tracking parameters.
• The page was rewritten and the slug now describes a different topic.
• You’re merging duplicate or overlapping pages into one.
• You’re moving to a new site structure or CMS anyway.

How to change a URL without losing traffic

Google’s redirects guide recommends a permanent server-side redirect when you change a page’s URL. A 301 or 308 tells Google the new URL should be the canonical one. Its site move guide adds the rest of the checklist:

1. Map every old URL to its new URL before changing anything.
2. Add a 301 redirect from each old URL to its new one, server-side.
3. Update internal links, the canonical tag and the XML sitemap so they all point to the new URL.
4. Keep the redirects “for as long as possible, generally at least 1 year.”
5. Expect rankings to fluctuate. Google says that for medium-sized sites it can take a few weeks or more before the new URLs replace the old ones in results.

If the old URL has links from other sites, a redirect is the only way those links keep reaching the page. That is why the cheapest fix for a weak URL is usually a better title. Before you plan a move, check how much URL control your CMS gives you, since slug and redirect settings vary by platform.

How to Measure a Title or URL Change

Use Google Search Console. In the Performance report, filter to the page and compare 28 days before the change with 28 days after it, starting once the change is live. It also helps to check which keywords a page ranks for before and after the change. If average position stays roughly the same and click-through rate rises, the title is working. If position drops after a URL change, check that the redirect returns a 301 or 308 and that internal links point to the new URL. Then give it the weeks Google says a move can take.

Search the main query yourself to see which title Google is showing. If it isn’t yours, it’s usually one of the rewrite triggers above. Google notes that changes are picked up only after a recrawl, which can take a few days to a few weeks, and you can request one with URL Inspection. For the wider picture of how titles, content and links fit together, see the SEO guide.

Put the Keyword in the Title, Keep the URL Stable

Google’s documentation is consistent on this. A keyword in the URL has hardly any ranking effect, and on mobile the URL doesn’t even appear in results. The title element is the main source of the headline people read and click. For new pages, write a short, readable, hyphenated slug once, then put the effort into a distinct title that matches the H1. For existing pages, improve the title and leave the URL alone unless it is actually wrong. If it is, use a permanent redirect and a migration checklist.
