How to Make a Slug From a Title (Without Breaking Links)

October 17, 2026 • NOFYI Editorial Team

A slug is the short, readable part of a web address that comes after the domain name. If a post is called How to Make a Slug From a Title, its slug might be how-to-make-a-slug-from-a-title. Readers use it to guess what the page is about before they click, and search engines use it as one small signal about the topic. A good slug is short, clear, and stable. It does not try to stuff in every keyword, and it does not change every time someone edits a headline.

Many people meet slugs for the first time when they publish a page and notice the address looks messy. It may contain capital letters, spaces shown as codes, extra words, or symbols that do not belong in a link. The fix is usually simple, but the timing matters. Changing a slug before a page is published is harmless. Changing it after people have linked to it, shared it, or bookmarked it can break those links unless you set up a redirect. That is why this guide treats the slug as a small decision with lasting effects.

What a Slug Should Look Like

A strong slug uses only lowercase letters, numbers, and hyphens. It keeps the most important words from the title and drops the rest. It avoids stop words such as a, an, the, and, or, of, and to when they add no meaning. It also avoids punctuation, symbols, underscores, and spaces. The result should be easy to read aloud, easy to type, and easy to remember.

Think of the slug as a label, not a sentence. The title does the work of attracting attention and explaining the topic in full. The slug only needs to identify the page. If a title is long, the slug can be shorter. If a title is vague, the slug should still be specific enough that someone seeing the link alone can tell what they will find.

How to Make a Slug From a Title

Start with the title exactly as you plan to publish it. Read it once and underline the words that carry the meaning. For a title such as How to Make a Slug From a Title (Without Breaking Links), the carrying words are make, slug, title, breaking, and links. The words how and to help the sentence, but they are not essential in the address. A sensible slug keeps enough of them to stay natural, such as how-to-make-a-slug-from-a-title-without-breaking-links, or a shorter version such as make-a-slug-from-a-title.

Next, turn every word to lowercase. Capital letters in an address can create two different-looking links that lead to the same page, or to different pages on some servers, and that confusion is easy to avoid. Replace each space with a single hyphen. Remove parentheses, commas, apostrophes, question marks, quotation marks, and other punctuation. If the title contains an ampersand, write out the word and instead. If it contains a number, keep it when the number matters, such as a year or a count, and drop it when it does not.

Then check for repeated hyphens. When you remove punctuation, two words that were separated by a symbol can end up with two hyphens between them. Replace any double hyphen with a single hyphen. Remove a hyphen at the start or the end. Read the result aloud. If it sounds clear, it is probably clear on screen. If it sounds crowded, remove one more low-value word and read it again.

Finally, check the length. A slug of three to seven words works well for most posts. Longer slugs are not automatically wrong, but they are harder to share, easier to mistype, and more likely to be cut off in messages or search results. Shorter slugs are easier to remember, but they can become vague if they drop too much. Aim for the shortest version that still describes the page without guessing.

Worked Example

Suppose you are about to publish a post titled How to Make a Slug From a Title (Without Breaking Links). You want an address that is tidy, stable, and safe to share.

Step one is to copy the title and identify the core idea. The post explains how to create a slug, so slug, title, and links are the key terms. Step two is to write a first draft in lowercase: how-to-make-a-slug-from-a-title-(without-breaking-links). Step three is to remove the parentheses. That leaves how-to-make-a-slug-from-a-title-without-breaking-links. Step four is to check for double hyphens, leading hyphens, or trailing hyphens. There are none. Step five is to judge the length. At ten words, the slug is long, but every word adds meaning, and the full phrase matches the title closely. For a post whose main warning is about breaking links, keeping without-breaking-links is useful.

A shorter alternative is make-a-slug-from-a-title. It is easier to type and still describes the main task. The trade-off is that it drops the warning about links. Which one is better depends on the post. If the post is mostly a general how-to, the shorter slug is enough. If the post spends much of its space on redirects and broken links, the longer slug is more honest. In this case, the longer version is a reasonable choice because the warning is central, not a side note.

Before you publish, test the full address in a browser. Make sure it loads the right page, that no strange characters appear, and that the link can be copied and pasted without breaking across lines. If your publishing tool creates the slug automatically, look at what it produced. Automatic slugs often keep too many words or include a date, so a quick manual check is worth the minute it takes.

What Not to Do

Do not use underscores instead of hyphens. Search engines and readers treat hyphens as word separators, while underscores can join words together in ways that make the address harder to read. Do not use spaces. Browsers may replace a space with a code that looks messy and can break in some tools. Do not use capital letters, even if the title uses them. Do not add a long string of keywords in the hope of ranking better. A slug is not a place to list every related term.

Do not change a published slug without a plan. If you rename a post, the old address may still be linked from other pages, search results, newsletters, social posts, and bookmarks. If you change the slug and do nothing else, those visitors may reach a not-found page. The safe approach is to keep the old slug when you can, or set up a redirect from the old address to the new one and test it before you announce the change.

Do not include dates in a slug unless the date is part of the topic. A post about a specific event in a specific year may benefit from the year, but a general guide does not. A date in the address can make useful content look old, even when the advice is still current. If your system adds a date automatically, check whether you can remove it or use a simpler address structure.

Limitations

A good slug helps readers and keeps links tidy, but it does not rescue weak content. A clear address will not make a thin post useful, and it will not fix a confusing title. It is one small part of publishing, not a shortcut to attention. Treat it as hygiene, not as a strategy on its own.

Slugs also have limits as descriptions. A short slug cannot carry every nuance of a long post. Some topics need more words to be accurate, and some titles contain terms that lose meaning when shortened. When a slug feels too vague, it is better to keep one or two extra words than to publish an address that misleads readers about what they will find.

Finally, different publishing systems handle slugs in different ways. Some add a category or a date before the slug. Some limit the length. Some change special characters automatically. Learn how your own system behaves, and check the final address after publishing rather than assuming the draft version stayed the same.

Frequently Asked Questions

Should a slug match the title exactly?

Not always. It should reflect the title, but it can be shorter. Remove punctuation, capital letters, and words that add no meaning. Keep the words a reader needs to recognize the topic. If the title is already short and clear, an exact match in lowercase with hyphens is often the best choice.

Are hyphens better than underscores?

Yes. Hyphens are the common standard for web addresses. They separate words clearly for readers and for search engines. Underscores can make words look joined together, and they are harder to see in underlined links. Use hyphens every time.

Can I change a slug after publishing?

You can, but you should avoid it unless you have a good reason. If you do change it, set up a redirect from the old address to the new one, update any links you control, and test the old link to confirm it sends visitors to the right page. Without a redirect, people who saved or shared the old address may reach a missing page.

How long should a slug be?

For most posts, three to seven words is a practical range. A shorter slug is easier to share, while a longer slug can be more specific. If a slug is longer than that, check whether every word earns its place. Remove filler words first, and keep the terms that describe the topic.

When you make a slug, slow down for one minute. Lowercase it, use hyphens, keep it short, and leave a published slug alone unless you can redirect the old address. That small habit protects your links and gives every post a clean address that readers can trust.
