Short links are typed by humans, printed on things, and read out loud. Sooner or later somebody lands on yourdomian.com/sale — and without a fallback, they get a bare "no redirect configured" page. A fallback URL catches every request a domain can't match and sends it somewhere useful instead.
Setting one
Open My Domains, pick the domain, and set fallback for unmatched links to any full URL — your homepage, a "link not found" page, a "we moved" notice. Both the bare domain and its www form are covered automatically.
How it decides
- Real links always win. A fallback only fires when nothing matches — it never overrides an actual redirect, bio page, or for-sale page on the domain.
- It's a 302, always. The catch-all is temporary by nature; permanent caching would be the wrong behavior for a page that exists to absorb mistakes.
- Mistakes aren't clicks. Fallback visits aren't logged against any link — your analytics stay honest.
What to point it at
- Homepage — the simplest choice: a typo still introduces someone to your site.
- A dedicated "link expired" page — explain that the link they followed is old, and offer the three links people usually want. Pairs beautifully with scheduled links: when a promo window ends, its visitors flow here.
- For domains you resell or park — point every unconfigured domain's fallback at your portfolio or inquiry page.
One domain, one decision
The fallback is a property of the whole domain, not of any single link — set it once and every current and future typo'd path is covered, including links you deleted months ago.
