Usability of Short URLs
Most short URLs do not provide clues about their destination. That’s why we created USA.gov short URLs. We wanted users to click with confidence and know they will reach official government information.
When creating Go.USA.gov, we assumed most users would be clicking short URLs, not typing them into a web browser. We’ve found that using short URLs in printed materials (posters, flyers, brochures, etc.) creates a poor user experience. Read more about this and suggestions for fixing it.
Accessibility of Short URLs
Short URLs can actually be beneficial for people using assistive technologies because it shortens the reading time and the cognitive load that longer URLs can create. Imagine listening tohttp://www.usa.gov/Citizen/Topics/Government-Unclaimed-Money.shtml being read aloud versushttp://go.usa.gov/WhzY.
With that in mind, you should avoid using the short URL as the link title, such as “Click here” (It’s never a good idea to use “click here,” but that’s a story for another day.) It’s ok to use a short URL as the link when you use actual words as the link title, such as “Learn more about short URLs.”
You can’t follow this rule when writing messages for social media because there isn’t the option to use a link title. Instead, give a good description first so users can decide if they want to click the link, such as “You can learn more about how to create short .gov URLs at http://go.usa.gov/Whtm.” Learn more about making social media accessible.
Search Engine Optimization (SEO) of Short URLs
URL shorteners that use 301 “permanent” redirects do not have negative effects on SEO. Both Go.USA.gov and bitly.com (the service that powers 1.USA.gov) use this type of redirect.
Commercial search engines treat short URLs with 301 redirects just like any other link. The short URL’s destination page will receive the social promotion bump and other SEO data (such as anchor text and position on the page) will be passed on too.
