When you're setting up automated monitoring to check for broken links across your file hosting URLs, importing hundreds of links without knowing what you're getting into can lead to unexpected quota usage, slower check times, and confusion about why some links take longer than others. DeadLinkRadar's classification preview solves this by analyzing your URLs before import, showing you exactly what to expect from your dead link checker setup.
This guide walks you through the classification preview feature, explaining how it helps you make informed decisions about which links to import and how they'll impact your link monitoring workflow. Whether you're managing a small collection of download links or thousands of file hosting URLs, understanding classification before import saves time and prevents surprises.
Quick Start

Why Classification Matters for Broken Link Detection
Not all links are created equal when it comes to checking for dead links. When you paste 100 URLs into DeadLinkRadar, those links may behave very differently during monitoring. Understanding these differences before you import helps you plan your dead link checker workflow effectively and avoid unexpected resource usage.
💡 Key Insight: Not all link checks are equal. Standard links check in 1-3 seconds. Protected links take 30-60 seconds and consume bypass quota.
Standard Links check quickly using our standard monitoring approach. These include most file hosting services like K2S, Nitroflare, Rapidgator, Mega, and Google Drive. Each check typically completes in 1-3 seconds, making them efficient to monitor at scale.
Protected Links require additional processing to verify availability. These are links from services that employ advanced protection mechanisms to prevent automated access. While DeadLinkRadar handles this automatically, each protected link check takes 30-60 seconds and consumes bypass quota.
⚠️ Common Pitfall: Importing 50 protected links without checking the preview can unexpectedly deplete your bypass quota and result in 25+ minute check times instead of the 2 minutes you expected.
Accessing the Classification Preview
The classification preview appears automatically during bulk import. Here's how to reach it:
- Navigate to your dashboard and click Add Links
- Choose your import method (Paste Links, Upload CSV, or Upload JSON)
- Enter or upload your URLs
- Click Add Links to begin validation
After initial URL validation, DeadLinkRadar analyzes each link and displays the classification preview modal.

Understanding the Classification Breakdown
The classification preview organizes your links into clear categories with visual indicators:
URL Breakdown Panel
The top section shows a summary of your links split by classification:
| Category | Icon | Description | Check Time |
|---|---|---|---|
| Standard | 🌐 Globe | Links without advanced protection | ~1-3 seconds each |
| Protected | 🛡️ Shield | Links requiring bypass processing | ~30-60 seconds each |
This breakdown helps you immediately understand what you're importing. A batch with 45 standard links and 5 protected links will behave very differently from one with 5 standard and 45 protected links.
Time Estimate
Below the breakdown, you'll see an estimated total check time. This calculation considers:
- Number of standard links × average standard check time
- Number of protected links × average protected check time
- Concurrent processing capabilities
For example, importing 20 standard links might show "~30 seconds" while 20 protected links would show "~15 minutes".
Quota Impact Analysis
The most critical section for paid plan users is the bypass quota panel. This appears when your import includes protected links and shows:
Current Usage - How many bypass credits you've used this billing period
After Import - Projected usage if you import all protected links
Limit - Your plan's monthly bypass quota
Status Indicator - Green "Sufficient" badge if you have enough quota, or red "Exceeds Limit" warning if the import would push you over
The quota panel displays a progress bar visualization showing your current usage and projected usage after import, making it easy to see at a glance whether you have sufficient quota for the import.
Selective Import Options
The classification preview isn't just informational. It lets you choose exactly what to import based on the analysis:
🎯 Smart Feature: Use selective import to stay within quota limits while still monitoring your most critical links. Import standard links now, protected links next billing cycle.
Import All Links
The default option imports every valid URL regardless of classification. Choose this when:
- You have sufficient bypass quota
- Check time estimates are acceptable
- You want complete monitoring coverage
Standard Links Only
Import only links that don't require bypass processing. Choose this when:
- You want to conserve bypass quota
- You need faster initial check completion
- Protected links aren't critical to monitor immediately
Protected Links Only
Import only links requiring bypass processing. Choose this when:
- Standard links are already monitored elsewhere
- You specifically need to track protected content
- You have quota to spare and want focused monitoring
Within the preview modal, checkboxes allow you to include or exclude each category from the import. Simply uncheck a category to exclude those links from the current import.
Viewing URL Details
Want to know exactly which links fall into each category? The classification preview includes an expandable details section:
- Click View URL details to expand the list
- Each URL shows its detected service and classification icon
- Protected links display the shield icon (🛡️)
- Standard links display the globe icon (🌐)
This transparency helps you verify the classification is correct and identify any unexpected categorizations.
Real-World Import Scenarios
Here's how the classification preview helps in common situations:
Scenario 1: Mixed File Hosting Batch
You're importing 100 links from various file hosts:
- 75 from K2S, Nitroflare, Mega (standard)
- 25 from a protected service
Classification preview shows:
- 75 Standard (~2 minutes total check time)
- 25 Protected (~20 minutes total check time)
- Bypass quota: 25 credits needed
Decision: If quota is limited, import standard links first, then add protected links next billing cycle.
Scenario 2: Single Protected Source
You're importing 50 links from a single protected file host:
- 0 Standard links
- 50 Protected links
Classification preview shows:
- 0 Standard
- 50 Protected (~40 minutes total check time)
- Bypass quota: 50 credits needed
Decision: Check if 50 credits fit within your monthly quota. If not, consider upgrading or splitting the import across billing periods.
Scenario 3: Quota-Constrained Import
You have 10 bypass credits remaining this month but want to import 30 protected links:
Classification preview shows:
- Quota after import: 30 / 10 limit
- Status: ❌ Exceeds Limit
Decision: Import only 10 protected links now, or switch to "Standard Links Only" filter if any standard links exist in the batch.
Pro Tips for Optimal Imports
Batch by Classification
When importing large link collections, consider separating them by source type first. Import standard links in one batch and protected links in another. This gives you better control over quota usage and check timing.
Monitor Quota Throughout the Month
Check your bypass quota usage before large imports. Navigate to Settings → Plan to see current usage. Planning imports around your quota renewal date maximizes what you can monitor each cycle.
Prioritize Critical Links
If quota is limited, import your most important protected links first. Standard links can be imported in bulk anytime without quota concerns.
Use the Details View
Before confirming an import, expand the URL details to verify classifications. Occasionally, a link might be categorized differently than expected due to URL structure or service detection. Catching this early saves surprises later.
Understanding Service Detection
DeadLinkRadar detects over 40 different file hosting services and platforms. Each URL is analyzed against known patterns:
Service-Specific Adapters - Links matching known services (K2S, Nitroflare, Mega, etc.) receive specialized monitoring with accurate status detection.
Protected Service Detection - Certain services are flagged as protected based on their access requirements. This classification is automatic and based on our service database.
Generic Fallback - URLs not matching any known service use standard HTTP monitoring. These are always classified as standard links.
The classification happens in real-time during the preview phase, so you always see accurate categorizations before committing to an import.
Troubleshooting Classification Issues
"All my links show as protected"
This typically happens when importing from a single protected source. Consider:
- Verifying you have sufficient bypass quota
- Importing in smaller batches over time
- Checking if the service really requires protection (contact support if unsure)
"Classification doesn't match expected service"
URL structure matters for detection. Ensure links are:
- Complete URLs with proper scheme (https://)
- Not shortened or redirected
- Using the service's primary domain
"Quota shows exceeded but I haven't imported yet"
The preview shows projected usage after import. Your current quota is fine; the warning indicates the import would exceed limits. Use selective filtering to stay within bounds.
Best Practices for Dead Link Monitoring at Scale
Managing a large library of download links requires a systematic approach to broken link detection. Here are proven strategies for effective link monitoring:
Organize by Source
Group your links by source service before importing. This makes it easier to understand classification patterns and predict quota usage. For example, if you have 200 K2S links and 50 links from a protected service, importing them in separate batches gives you more control over the monitoring workflow.
Set Up Alert Thresholds
After importing your links, configure alerts to notify you when links become broken. DeadLinkRadar supports multiple notification channels including email, Slack, Discord, and webhooks. Setting up alerts ensures you catch dead links quickly and can take action before users encounter them.
💡 Pro Tip: Set up alert notifications immediately after importing. Catching broken links within hours instead of days can save your user experience.
Schedule Regular Checks
The classification preview shows estimated check times, which helps you plan appropriate monitoring schedules. Standard links can be checked frequently (every few hours) with minimal resource impact. Protected links may benefit from less frequent checks (daily or weekly) to optimize quota usage.
Review Classification Regularly
As services evolve, classification patterns may change. A service that was standard last month might become protected, or vice versa. Periodically reviewing your link classifications ensures your monitoring remains efficient and your quota projections stay accurate.
Monitor Your Dead Link Metrics
Keep track of your overall broken link rate over time. If you notice certain services consistently producing dead links, consider checking them more frequently or replacing them with more reliable alternatives. The classification preview helps you identify these patterns early by showing which services your links belong to.
Summary: Making Informed Import Decisions
The classification preview transforms bulk importing from a guessing game into an informed decision when setting up your dead link checker:
- Analyze before importing - See exactly how links are categorized and what to expect
- Understand quota impact - Know how many bypass credits you'll use before committing
- Estimate check times - Plan for standard vs. protected processing speeds
- Import selectively - Choose all, standard only, or protected only based on your needs
This transparency helps you manage your broken link monitoring budget effectively and avoid surprises when links take longer to check or quota runs low unexpectedly. The preview feature ensures you always know what you're importing and how it will affect your dead link detection workflow.
Whether you're checking for broken links across a handful of URLs or thousands of file hosting links, the classification preview gives you the visibility needed to make smart decisions about your monitoring setup.
