Learn how to set up a branded short domain for your business. Using a custom domain with a URL shortener increases click-through rates, brand trust, and link shareability.
Why a Custom Domain Changes Everything
Generic URL shorteners use shared domains like bit.ly/xyz or goo.gl/abc. While they work, they don't build brand recognition. When you use a custom domain — for example go.acmecorp.com or links.yourbrand.me — every single link you share becomes a branded digital asset.
Studies show that branded short links receive up to 34% more clicks than generic shortened URLs. Why? Because people trust links that include a recognizable brand name.
Step-by-Step: Setting Up a Custom Domain on 4Srt
Step 1: Choose Your Domain
Pick a short, memorable domain that complements your brand. Common patterns:
go.yourdomain.com— subdomain of your existing domainlinks.yourbrand.com— descriptive subdomainyourco.link— entirely new short domain (requires registration)
Pro Tip: Subdomains are the easiest to set up since you already own the parent domain. A new .link, .io, or .me domain can cost as little as $1/year.
Step 2: Register the Domain (if needed)
If you don't already own a short domain, register one through a domain registrar like Namecheap, Cloudflare, or GoDaddy.
Step 3: Add the Domain to 4Srt
- Log in to your 4Srt dashboard
- Navigate to Custom Domains
- Click Add New Domain
- Enter your domain (e.g.,
go.yourdomain.com) - Note the CNAME target that 4Srt provides
Step 4: Configure DNS
Go to your domain registrar's DNS settings and add a CNAME record:
DNS propagation typically takes 1 to 24 hours, though it's often much faster.
Step 5: Verify the Domain
Return to 4Srt's Custom Domains section and click Check Status. Once verified, you'll see a green ✅ indicator.
Creating Branded Links with Your Custom Domain
After verification, all new links will automatically use your custom domain:
- 4Srt dashboard: create link → select your domain
- API: specify
domainin the request body - Team members can also use your domain if added to a shared team
Benefits of Custom Domain URL Shorteners
Social Media Credibility
On platforms like LinkedIn, Twitter/X, and Instagram, a custom short domain looks far more professional than a generic shortener.
Email Campaign Performance
Email security filters are suspicious of generic shorteners. Your own domain avoids spam filters and boosts deliverability.
Analytics Ownership
All click data belongs to you — not a third-party service. If the shortener ever shuts down, your domain still exists.
SEO Value
While short links themselves aren't directly a ranking factor, branded links that get clicked signal engagement — and engagement is a ranking signal.
Common Questions
Can I use multiple custom domains?
Yes — on the Pro plan, you can connect up to 5 custom domains. The Business plan supports unlimited domains.
What if I misspell the CNAME record?
Simply delete the incorrect record and add the correct one. DNS propagation will update within a few hours.
Can team members use my custom domain?
Absolutely. Add team members to your workspace and they can create links using any of your verified domains.
Conclusion
A custom domain URL shortener is one of the most cost-effective branding upgrades you can make. Setup takes less than 30 minutes, and the benefits — higher click rates, better deliverability, and complete analytics ownership — compound over time.
