Common Questions
Are short links permanent?
It depends on the service. Most short links remain active as long as the service exists and the account is active. Enterprise solutions often guarantee uptime and permanence.
Can I see who clicked my link?
Most link shorteners provide analytics showing click counts, locations, devices, and referral sources - but not personally identifiable information about individual users.
Do short links affect SEO?
Short links use 301 redirects, which pass most SEO value to the destination page. However, it's best to use your actual URLs for important SEO content.
How small can a QR code be?
QR codes with short URLs can be quite small - typically 1x1 inch (2.5x2.5 cm) works well. Longer URLs require larger QR codes with more complex patterns.
