Frequently Asked Questions

Don’t worry.
The Free plan has a daily click limit, and when exceeded, a notice page will appear first.

Immediate solutions

• Upgrade to a paid plan: The limit is lifted immediately and you can continue using the service normally.
• Non-member links: If you created a link without signing up, please contact support via [Contact Us].

Automatic reset

• Reset time: The limit automatically resets every midnight (00:00 – UTC +09:00).
• Temporary redirect: Even during the limit, after a short wait you will be redirected to the original URL.

💡 This is normal behavior under the Free plan’s daily click limit, so you can use it with confidence.

Cause

• If the link address contains a typo, it may connect to a different short link.

Common mistakes

• Case change: vvd.bz/AbC1 → vvd.bz/abc1 (recognized as a different link).
• Missing/extra character: vvd.bz/test123 → vvd.bz/test12
• Typo when entering manually.

Solutions

1. Check the exact link: Use the exact address saved when created.
2. Use copy & paste: Avoid manual typing and use the ‘Copy to Clipboard’ button.
3. Regenerate the link: If the problem persists, create a new short link and replace it.

Prevention

• Always test-click once before mass distribution.
• Backup generated links in a safe place.
• Correct format: https://vvd.bz/[linkId]
• The linkId is system-generated and case-sensitive.
• Even one different character is treated as a completely different link.

💡 Always use copy & paste and perform a test click before sending.

If the issue continues

Please leave the following details via the [Contact Us] page:

• Registered email address.
• Email service in use (Gmail, Naver, etc.).
• Frequency of re-verification requests.

💡 Once emails are received normally, re-verification requests will automatically stop.

Reasons for the difference

• Other sites: Count all visits as clicks.
• Vivoldi: Counts only real user clicks (more accurate).

How Vivoldi measures clicks

• Included: Genuine user clicks.
• Excluded:
• Re-clicks within 5 seconds (to prevent double-counting).
• Malicious bots/crawlers (automatically blocked).
• SNS/blog preview access (system checks).

Common patterns

• Vivoldi clicks < Other sites → Normal (due to exclusion of bots/duplicates).
• Vivoldi clicks > Other sites → Can happen due to SNS previews, etc.

Accuracy

• Vivoldi tracks only real users and filters bots & spam traffic, providing more reliable data for marketing & analytics.

💡 For accurate comparison, review data over a period of time rather than short-term counts.
