Blacklist - Block Fraudulent IPs and Placements

The Blacklist page allows you to manually block specific IP addresses, IP ranges, and app/domain placements from seeing your ads. Unlike automatic exclusions, blacklist entries are user-controlled and permanent until removed.

Overview Metrics

Four cards at the top summarize your blacklist status:

Adding to Blacklist

Click the + Add to Blacklist button (blue button, top-right of the table) to add a new entry.

Entry Types

The table displays all blacklist entries with the following columns:

• Shows date and time
• Invalid dates may display as "Invalid Date" for demo data

Exclusions

• Shows count (e.g., "0" if newly added)

Use the date range picker to filter which entries are displayed based on when they were created.

Blacklist vs Exclusions

Understanding the difference:

When to Use Blacklist

Competitor IPs

If you know your competitor's office IP addresses, add them to prevent click fraud and wasted ad spend.

Internal Traffic

Block your own company's IP addresses to avoid inflating click counts and wasting budget.

Known Fraud Sources

If you identify a source of fraudulent activity through analytics or reports, add it manually.

Problematic Placements

Block websites or apps where your ads perform poorly or attract low-quality traffic.

Removing Entries

To remove a blacklist entry:

1. Find the entry in the table
2. Click the delete/remove icon on the row
3. Confirm the removal

Best Practices

1. Document reasons — Always add notes explaining why you blocked something
2. Review periodically — Old entries may no longer be relevant
3. Use ranges sparingly — Blocking large IP ranges can affect legitimate users
4. Coordinate with team — Make sure team members know about manual blocks
5. Check exclusions first — ClickFortify may have already blocked it automatically
