Frequently Asked Questions

Should I use hyphens or underscores in slugs?

Always use hyphens (-). Google treats hyphens as word separators, so "my-blog-post" is read as three separate words. Underscores are treated as word joiners, making "my_blog_post" read as one word. Hyphens are the SEO best practice.

What does transliteration do?

Transliteration converts accented or non-ASCII characters to their closest ASCII equivalents. For example, "café" becomes "cafe", "Zürich" becomes "zurich", and "ñ" becomes "n". This ensures URLs work correctly across all browsers and servers.

How long should a URL slug be for SEO?

Keep slugs under 50-60 characters. Google typically displays up to that many characters in search results. Include your primary keyword early in the slug. The tool's max length option helps you enforce this limit with clean word-boundary truncation.

What are stop words and should I remove them?

Stop words are common words like "the", "a", "and", "of" that search engines often ignore. Removing them makes slugs shorter and more keyword-focused. However, for brand names or phrases where stop words carry meaning (like "The Who"), keep them.

Can this tool handle Chinese text?

Yes. Chinese characters are valid in modern URLs (percent-encoded). The tool preserves CJK characters, Cyrillic, and other Unicode scripts while stripping spaces and special symbols like & and #, generating clean slugs like "10-个提升网站-seo-排名的实用技巧".

Can I change a slug after publishing without breaking links?

Technically yes, but every change breaks the old URL: existing bookmarks, shared links, search results, and backlinks start returning 404s until you add 301 redirects from the old slug to the new one. Decide the slug before publishing, and treat any later change as a migration task: redirect each old URL, update internal links, and resubmit the new URL in search console. Some CMS platforms let you change slugs and create the redirect automatically, but most do not.

What do good and bad URL slugs look like?

A good slug is short, descriptive, and readable: /blog/best-running-shoes-2026 beats /p/2874 or /blog/post.php?id=3. Use lowercase, hyphens between words, your primary keyword early, and no dates unless the content is date-specific (news). Avoid stop words when they add nothing ('the', 'and'), IDs and query strings, and characters like &, %, or spaces. They get percent-encoded and are hard to read and share.

Can I use this tool for generating file names?

Absolutely. The same slug rules apply to file names: lowercase, hyphens or underscores for spaces, no special characters. Set the separator to underscore (_) if your file system prefers that format. The tool is great for generating clean, consistent file names for images, documents, and downloadable assets.

What characters are removed from slugs?

The tool removes all characters except letters, numbers, spaces, and the chosen separator. This includes punctuation marks (!@#$%^&*), special symbols, emoji, angle brackets, and URL-unsafe characters. Multiple consecutive spaces are collapsed into one. For URLs, this ensures the slug is universally compatible across all browsers and servers.

Why is my Chinese title slug empty or garbled?

Slug generation transliterates to ASCII by default, and Chinese characters have no Latin representation, so a pure-Chinese title can produce an empty or stripped slug. Options: enable the Pinyin/transliteration option if the tool provides one, or keep the Chinese characters and use a slug that allows non-ASCII (some CMS platforms support UTF-8 slugs, e.g. 中文-标题). If neither is available, add a Latin keyword to the title so the slug has content. This is a limitation of ASCII slugs, not a bug.

What is a URL slug and why does it matter for SEO?

A URL slug is the last, human-readable part of a URL that identifies a page: in https://example.com/blog/how-to-make-coffee, 'how-to-make-coffee' is the slug. It matters for SEO because search engines display it in results and use it as a relevance signal, and because descriptive slugs get more clicks. Keep slugs short (3-5 words), use hyphens between words, and include the main keyword where it reads naturally. Online slug generators and slugify tools automate these rules. This page is one such generator.

Why doesn't my keyword-rich slug improve my search ranking?

Slugs are a minor ranking signal. Google has stated that URL keywords carry little weight compared to content relevance, backlinks, and on-page signals. What a clean slug does help with is click-through rate: readable, keyword-containing URLs look more trustworthy in search results, and CTR itself is a meaningful signal. Don't expect ranking jumps from slug tweaks alone; do use slugs for clarity and CTR.

Can I generate slugs in bulk for a whole list of titles?

Not in this tool. It processes one title at a time. For bulk work: paste your titles one per row into a spreadsheet and use a formula for simple cases, or run a slugify package over the list (slugify for Node, python-slugify, or the CMS's built-in bulk editor). Then spot-check the results here. This tool doubles as a reference implementation to confirm your bulk output follows the same rules (hyphens, lowercase, character stripping).

I used underscores and the slugs are already live, how do I fix it?

If the pages are not published yet, just regenerate with hyphens. Nothing breaks. If they are live, treat it as a migration: add 301 redirects from each underscore URL to the hyphen version, update internal links, and resubmit the new URLs in Search Console. The old URLs keep 404ing until the redirects exist. Google reads underscores as word joiners, so the SEO reason for hyphens is real, but the practical fix is the same as for any slug change: redirect, don't just swap.

Two of my titles generated the same slug, will that cause problems?

Yes, two pages cannot share one URL. At best your CMS appends a suffix (-2, -3) automatically; at worst the later page overwrites the earlier one or 404s. Either way you get duplicate-content signals or broken links. Fix before publishing: make the titles differ meaningfully (add the year, the product name, or a distinguishing term), then regenerate. The tool cannot see your other slugs; uniqueness is your job.
