Custom Aliases
& Expiration
Set custom aliases for branded URLs, add link expiration dates, and use auto-fetched titles and favicons.
Custom Aliases
Instead of a random code like lnkk.it/x7kP9m, set a custom alias to create memorable, branded URLs like lnkk.it/my-brand. Custom aliases are available when creating or editing any link.
Alias Rules
4 rules for custom aliases
Lowercase letters, numbers, and hyphens only
my-brand, sale2024, promo
Must be unique within the same domain scope
Two links can't share the same alias on lnkk.it
Custom domain aliases are scoped per domain
go.brand.com/sale and lnkk.it/sale can coexist
Original short code still works
Both lnkk.it/abc123 and lnkk.it/my-alias redirect
Note: If an alias is already taken, you'll see an error message. Try a variation or a more unique alias.
How to Set an Alias
Create or edit a link
Open the create modal (click "Shorten a Link") or edit an existing link from the dropdown menu.
Enter your alias
Type your desired alias in the "Custom Alias" field. Keep it short, memorable, and relevant.
Save
Click Create or Save. If the alias is available, your link now works at lnkk.it/your-alias (or yourdomain.com/your-alias if using a custom domain).
Link Expiration
Set an expiration date and time on any link. After the expiration, the short URL stops redirecting. This is perfect for time-limited campaigns, promotions, limited offers, or temporary access links.
Set the expiration in the "Expires At" datetime picker when creating or editing a link. You can also remove expiration by clearing the field.
Expiration States
3 visual states in your link list
Link lives forever — no countdown shown. This is the default.
Less than 24 hours remaining — shown with an amber countdown timer (e.g. "5h 30m left").
Past the expiration date — marked with a red "Expired" badge and sorted to the bottom of your list.
Smart Auto-Features
3 things that happen automatically
Auto Title
When you create a link without a title, Lnkk.it fetches the page's <title> tag and uses it as the link title. This makes your link library easier to browse.
Auto Favicon
The destination site's favicon is automatically fetched and displayed as the link icon. This gives visual context in your link list.
URL Normalization
URLs are automatically cleaned up — https:// is added if missing, and whitespace is trimmed. You can paste raw URLs without worrying about formatting.
Link Limits
Tips
Keep aliases short and descriptive — "summer-sale" is better than "summer-sale-2024-promo-v2"
Use hyphens to separate words for readability — lnkk.it/my-event reads better than lnkk.it/myevent
Don't set expiration on links used for QR codes on permanent print materials
Use expiring links for contest entries, limited-time downloads, or event RSVPs
The original random short code always works even after adding an alias — nothing breaks
Auto-fetched titles and favicons save time — only override them when you need a custom label
