Questions people actually ask
Four small checks that catch real mistakes: campaign links that lose their attribution, slugs that break on accented characters, robots rules that block the wrong path, and sitemaps that promise URLs which no longer exist.
What is a UTM parameter and do I need one?
UTM parameters are tags on a link that tell your analytics where a visitor came from. Without them, traffic from a newsletter and traffic from a paid ad look identical, and you cannot tell which one worked.
How do I make a URL slug from a title with accents?
Paste the title. The slug generator folds accented characters to their closest ASCII equivalent, so 'Café Münchén' becomes 'cafe-munchen' rather than losing the words entirely or emitting percent-encoding.
Will this validate my robots.txt?
It generates rules and flags the common mistakes, including disallowing a path you probably meant to keep crawlable. It does not fetch your live file — nothing on this page makes a network request.
Is any of this sent to a server?
No. All four tools run in the browser.
