Frequently Asked Questions About Slug Collision Disambiguator
What is a slug collision?
A slug collision occurs when two pages would have the same URL slug (e.g., two blog posts both titled "Hello World" would both want /hello-world). The disambiguator resolves this by appending suffixes.
How are suffixes applied?
The first occurrence keeps the base slug. Subsequent duplicates get -2, -3, -4 appended. If the base slug already ends with a number, the tool handles it intelligently.
