Générateur de Slug

A good URL slug is short, descriptive, lowercase, and uses hyphens as word separators. Aim for three to five words that capture the primary keyword of the page. Drop stop words — the, a, of, and, for, with — unless removing them changes the meaning. For example, a post titled 'The Complete Guide to PDF Compression in 2025' works best as /pdf-compression-guide/. That slug keeps the two ranking keywords, drops the year so you never need to rename it, and stays short enough to display in full in a search snippet. Google's documentation explicitly treats hyphens as word separators. Underscores, dots, and camelCase are treated as single concatenated tokens, which hurts keyword matching. Uppercase letters are technically fine but create duplicate-URL risk when servers behave differently on case. Keeping slugs lowercase eliminates that ambiguity entirely. Special characters, accents, and non-ASCII bytes get percent-encoded in transit: é becomes %C3%A9, a space becomes %20. Those codes look unprofessional in shared links, reduce click-through rates, and can cause caching mismatches on some CDNs. Our generator strips all of them, swaps accented Latin characters for their ASCII equivalents, and limits the output to your chosen max length. Practical tip: choose the slug before you publish, not after. Changing a slug on a live page requires a 301 redirect and risks a four-to-eight-week ranking dip while Google recrawls the new URL.

Not exactly, but closely enough to carry the main keyword signal. The page title serves readers; the slug serves both readers and crawlers. Titles are often long, include the year, include a count, or carry emotional language that adds no ranking value in a URL. A title like '17 Proven Ways to Speed Up Your WordPress Site in 2025' should become /speed-up-wordpress-site/ in the slug. That preserves the two core keywords — speed and wordpress — that anchor the page's ranking intent. It drops the count, which you would have to update when you add an eighteenth tip. It drops the year, which you would have to update every January or accept a stale-looking URL. It drops 'proven' and 'ways', which carry no keyword weight in URL position. The slug should also avoid keyword stuffing. A slug like /best-free-online-wordpress-speed-optimization-tool-guide-2025/ is longer than most search snippets can display. It gets truncated in results. Search engines do weight keyword placement in URL paths, but they apply diminishing returns past two or three keywords. Shorter slugs are easier to remember, easier to type, and easier to link from anchor text. If the title changes after publication — headline testing is common — the slug does not need to follow. Practical tip: lock the slug at publication time and let the title evolve independently.

Yes, but every slug change on a live page carries a real SEO cost if you do not handle the redirect correctly. When you change a slug, the old URL becomes a 404 unless you immediately set up a 301 permanent redirect from the old path to the new one. A 301 tells search engines that the move is permanent and transfers most of the link equity from the old URL to the new one. Without the redirect, every inbound link, bookmark, and indexed cache of the old URL produces a dead end. You lose all the PageRank that page accumulated. You also lose traffic from anyone who saved the link. Even with a correct 301, expect a ranking fluctuation of four to eight weeks while Google recrawls both URLs, processes the redirect chain, and reindexes the content under the new path. External sites that linked to you will still point at the old URL. Those links remain valuable only while the redirect is active. If you ever delete the redirect rule, those links become dead again. Set redirects in your web server configuration, CDN rules, or CMS redirect plugin. Verify them with a curl or browser request before announcing the change. Check Google Search Console's Coverage report two weeks after the change to confirm the old URL shows a redirect and the new URL is indexed. Practical tip: get the slug right before the first publish. The cost of changing it later is always higher than the cost of thinking it through on day one.

The generator applies a transliteration map for accented Latin characters before producing the final slug. The letter é maps to e. The letter ñ maps to n. The letter ü maps to u. The letter ç maps to c. The German eszett ß maps to ss. The Polish ł maps to l. The Czech š maps to s. These swaps follow the most widely accepted ASCII equivalents for each character, matching the transliteration rules used by major CMS platforms and URL normalization libraries. The result is a clean ASCII slug that works on every CDN, web server, database column, and URL parser without encoding issues. For non-Latin scripts — Cyrillic, Greek, Arabic, Hebrew, Chinese, Japanese, Korean, Thai, and others — direct character-to-character ASCII swaps are ambiguous because romanization systems differ. By default the generator removes characters from these scripts entirely. If you need to preserve the non-ASCII form, for example for an hreflang-targeted URL structure, toggle the 'allow non-ASCII' option. Modern browsers display these URLs correctly in the address bar through Unicode normalization. However, when those URLs are copied as plain text into email, chat, or social media, they are percent-encoded, which produces long unreadable strings that hurt click-through rates. Practical tip: for international SEO across six or more languages, use translated slugs in ASCII form rather than romanized native-script slugs.
