Question 1

What is a URL slug?

Accepted Answer

A URL slug is the part of a URL that identifies a specific page in a readable format. For example, in '/blog/how-to-use-slugs', the slug is 'how-to-use-slugs'. Slugs use only lowercase letters, numbers, and hyphens.

Question 2

Why use hyphens instead of underscores in slugs?

Accepted Answer

Google treats hyphens as word separators but underscores as joiners. 'word-count' is read as two separate words, while 'word_count' is read as one. For SEO, hyphens are recommended in URL slugs.

Question 3

What characters are removed from slugs?

Accepted Answer

All characters that are not letters, numbers, hyphens, or underscores are removed. This includes accented characters, punctuation, and symbols. Leading and trailing separators are also stripped.

Question 4

What does the max length option do?

Accepted Answer

The max length option truncates the slug to the specified number of characters. The truncation happens after conversion, so the result will not end with a hyphen or underscore.

Question 5

Can I use the generated slug directly in a URL?

Accepted Answer

Yes. The output contains only URL-safe characters (lowercase letters, numbers, and the chosen separator). No additional encoding is needed.
