Custom Short Link: Create Memorable URLs That Reflect Your Brand

A short link that reads like random noise does its job of shrinking a URL, but it does nothing for your brand. A custom short link, by contrast, transforms a compressed address into a marketing tool. Instead of relurl.com/x7k3m9, you get relurl.com/black-friday-sale or brand.link/new-product. The difference is trust, memorability, and click-through rate. Custom short links, also called vanity URLs, let you choose the trailing alias or the entire domain so every link reinforces your identity.

Why Custom Short Links Outperform Generic Short Links

Generic short links like bit.ly/abc123 or tinyurl.com/xyz789 serve one purpose: they shorten. They do not communicate anything about the destination, the brand, or the content. A user hovering over the link before clicking sees gibberish. That uncertainty reduces click-through rates because the link provides no signal about where it leads.

A custom short link eliminates that uncertainty. When a user sees yourdomain.com/summer-sale, they immediately know three things: the link belongs to your brand (via the domain), the content is about a summer sale (via the alias), and clicking is safe (because the branded domain signals authenticity). This triple signal dramatically improves engagement.

Custom short links also survive trust filters. Social platforms, email clients, and messaging apps are increasingly aggressive about blocking generic short links because they are frequently used in phishing campaigns. A branded domain passes these filters more easily because the domain reputation belongs to you, not a generic shortening service.

Elements of an Effective Custom Short Link

• Keep the alias short: Aim for three to five words maximum. A link like brand.link/ebook-download-2026 is better than brand.link/ebook-download-for-marketing-professionals-2026.
• Use hyphens between words: Hyphens improve readability and are universally supported. Avoid underscores, camelCase, or special characters that may break in some clients.
• Match the alias to the content: The alias should describe the destination accurately. A mismatch between alias and landing page creates cognitive dissonance and reduces trust.
• Avoid seasonal aliases for permanent links: If the link will be used long-term, choose a timeless alias. /spring-campaign creates confusion in autumn.
• Use lowercase consistently: Short links are case-sensitive in many systems. Lowercase eliminates ambiguity and is easier to communicate verbally.

Choosing the Right Custom Slug

The slug is the part of the custom short link that comes after the domain. It is your chance to embed meaning into the URL. A well-chosen slug improves recall, makes verbal sharing natural, and provides context before the click. A poorly chosen slug creates confusion, looks unprofessional, and undermines the trust you want to build.

For marketing campaigns, the slug should mirror the campaign name. If your campaign is called Project Elevate, use /elevate or /project-elevate. Consistency between the campaign name and the short link alias reinforces brand recall every time someone sees or clicks the link.

For content pieces like blog posts, whitepapers, or guides, use a condensed title. A guide titled The Complete Guide to Email Marketing Automation becomes /email-automation-guide. The slug should be recognizable but not necessarily identical to the full title. Short enough to type, long enough to be unique.

For event or webinar links, include the date or a memorable keyword. A webinar on March 15 might use /webinar-mar15 or /march-webinar. If the event recurs, include the year: /summit-2026 versus /summit-2027. This prevents confusion when sharing the same event name across different years.

Custom Domains vs. Custom Slugs

A custom short link can be customized at two levels. The domain level gives you a branded root: acme.co instead of relurl.com. The slug level gives you a descriptive path: acme.co/sale instead of acme.co/4fT2q. Both together create the strongest signal. A link like acme.co/sale tells the user everything they need to know before clicking.

Custom domains require a small configuration step. You verify domain ownership by adding a DNS record, typically a CNAME or TXT record. Once verified, the domain is available for all your short links. RELURL supports multiple custom domains per account, so you can use different domains for different brands, products, or campaigns.

Custom slugs are configured per link. When creating a short link in RELURL, you can enter a custom alias in the slug field. If the alias is already taken, RELURL suggests alternatives. You can also edit the slug of an existing short link, though the old slug becomes available for others to claim if you release it.

How Custom Short Links Improve Click-Through Rates

Multiple studies have measured the effect of custom short links on click-through rate. Branded short links consistently outperform generic short links by 30 to 50 percent across email, social media, and paid advertising. The reason is trust and recognition. A branded domain signals legitimacy in an environment where users are conditioned to be skeptical of links.

In email marketing, the effect is even more pronounced. Email clients scan links for suspicious patterns. A generic short link may trigger spam warnings or link unwrapping that strips the redirect. A branded custom short link passes through without triggering these protections because the domain is recognized as yours.

In social media posts, custom short links perform better in engagement metrics. Twitter, LinkedIn, and Facebook display the domain as part of the link preview. A branded domain like acme.co appears legitimate and invites clicks. A generic domain like shrt.svc appears anonymous and invites skepticism.

Best Practices for Custom Short Links Across Channels

Each channel has nuances that affect how your custom short link performs. For print materials like flyers, posters, and business cards, the slug must be short enough to type manually. A slug longer than fifteen characters is unlikely to be typed accurately. Use your custom domain plus a minimal slug: brand.link/offer rather than brand.link/special-offer-june.

For verbal sharing on podcasts, radio, or presentations, the slug should be easy to spell and pronounce. Avoid homophones (there/their/theyre), character names, or industry jargon that your audience may not know. Say the link out loud before finalizing it. If it sounds awkward, rewrite it.

For digital advertising, use UTM-tagged custom short links that match the ad creative. If your ad says Shop the Summer Collection, the short link should reflect that: brand.link/summer-collection. The alignment between ad copy and destination URL improves quality score on platforms like Google Ads and reduces bounce rate on the landing page.
