Generate a slug
Lowercase, hyphenated, no special characters - the format Substack and most platforms expect. Shorter slugs aren't required, but they're easier to read and share.
What makes a good URL slug
A clean slug is lowercase, uses hyphens instead of spaces or underscores, and avoids special characters - the format Substack and most publishing platforms expect by default. Beyond the technical format, shorter slugs that still include your target keyword tend to be easier to read, share, and remember than a slug that simply mirrors a long title word-for-word.
The shortened version strips common filler words (a, the, of, to, and similar) that add length without adding meaning to the URL. Removing them is optional, not required - Substack will accept either version.
Questions
What format does Substack expect for URL slugs?
Lowercase letters and numbers with hyphens between words, no spaces, underscores, or special characters - the standard format most publishing platforms use by default.
Should I use the full slug or the shortened version?
Either works technically. The shortened version (with common words like 'a' and 'the' removed) is easier to read and share; the full version keeps closer to your exact title. Pick whichever you prefer.
Does a shorter slug help SEO?
It's not a major ranking factor on its own, but a slug that's easier to read and still includes your target keyword is generally considered good practice over an unnecessarily long one.
Can I edit the slug after generating it?
Yes - both outputs are a starting point you can tweak by hand before pasting into Substack, not a locked final answer.
