Frequently Asked Questions

A URL slug is the human-readable part of a URL that identifies a specific page. For example, in https://example.com/blog/how-to-build-rest-api, the slug is how-to-build-rest-api. Good slugs are lowercase, use hyphens, and contain only letters, numbers, and separators.
URLs are technically case-sensitive (RFC 3986), so /Blog/Post and /blog/post are different URLs. Lowercase slugs avoid duplicate content issues and user confusion. Google recommends lowercase URLs.
Diacritics (accented letters like é, ü, ñ) are normalized using Unicode NFD decomposition, which separates base letters from their accent marks. The accent marks are then stripped, leaving the clean base letter — e.g., café becomes cafe.
A slug is the final segment of a URL: in /blog/how-to-bake-bread, the slug is how-to-bake-bread. A permalink is the full, permanent URL including the domain and path: https://example.com/blog/how-to-bake-bread.
Special characters should be removed or replaced. Common replacements: & becomes and; % becomes percent; # is removed. Characters like ?, =, and & are reserved in URLs and will break query string parsing if included literally.
There is no official maximum, but shorter slugs are generally better. Most SEO professionals recommend keeping slugs under 5–6 words and under 75 characters. Remove stop words (a, the, and, of) to shorten slugs without losing meaning.
Yes. Numbers are valid in slugs and are commonly used for years (/blog/2024/my-post), product IDs (/product/42), and version numbers (/docs/v3). This tool preserves all numeric characters in the output.
This tool handles diacritics (é → e, ü → u) via Unicode NFD normalization, but does not transliterate full non-Latin scripts like Arabic, Chinese, or Cyrillic. For those, server-side libraries like PHP's transliterator_transliterate() are needed.
A canonical URL is the preferred URL for a page when multiple URLs could show the same content. Consistent, clean slugs help prevent duplicate content. Always use lowercase slugs and set up 301 redirects from alternate URL formats to the canonical one.
Use hyphens. Google treats hyphens as word separators, so red-wine is indexed as two words. Underscores are treated as connectors — red_wine is indexed as a single word "red_wine". Hyphens improve keyword matching in search.

Flat vs nested slug structures, author page cardinality problems, tag proliferation diluting content quality signals, and when CMS-generated slugs from titles produce wrong results for numbers and acronyms. Here's the slug architecture decisions that affect content series, taxonomies, and international content, plus why the language identifier belongs in the path prefix rather than embedded in the slug itself.

When Changing a Slug Is Worth the SEO Cost — and the Exact Sequence to Follow When It Is
Changing a URL slug after publishing has permanent SEO consequences — but so does keeping a slug that contains a wrong date, a discontinued product name, or a keyword that's shifted. Here's when slug changes are genuinely warranted (vs when they're not worth the disruption), the correct 301-redirect-then-update-internal-links sequence, why CMS auto-slug-regeneration on title edit destroys rankings, and why year-in-slug is almost always a decision you'll regret.

Slug Collisions: What Happens When Two Pages Generate the Same URL, and How CMSs Handle It
