SEO Best Practices

Google and search engines recommend hyphens (-) instead of underscores to separate words. Slugs should be concise (3 to 6 keywords) without trailing punctuation.

Unicode Transliteration

Non-ASCII characters like accents and umlauts (café → cafe, münchen → munchen) are automatically converted to clean Latin ASCII to avoid ugly URL percent-encoding (%C3%A9).

Stop Words Removal

Filtering stop words (the, a, and, for) shortens lengthy headlines, focusing crawling priority on high-value topical keywords while keeping the permalink clean.

Frequently Asked Questions

Why are hyphens preferred over underscores for URL slugs?

Google and major search engines treat hyphens as natural word separators (treating 'web-development' as two distinct keywords), whereas underscores often treat words as concatenated single terms ('web_development').

How does the tool handle accented and international characters?

The generator uses Unicode NFD normalization to strip diacritics and replaces ligatures (e.g., 'café' becomes 'cafe', 'münchen' becomes 'munchen', and 'ß' becomes 'ss'), preventing ugly percent-encoded URLs like '%C3%A9'.

What is the recommended maximum length for an SEO URL slug?

Most SEO best practices recommend keeping URL slugs under 50 to 60 characters and focusing on 3 to 5 core keywords. The generator includes an optional length limit with smart word-boundary backtracking.

Is my text uploaded to any server?

No. All string manipulation, transliteration, and slug formatting happens 100% locally inside your browser. No data is sent over the network.
