How to Check Proxy Quality

Introduction

A quality proxy is essential for reliable operations. This guide covers the key metrics you should evaluate when testing proxies.

Key Quality Metrics

1. Latency (Response Time)

Latency measures how quickly the proxy responds to requests. Lower is better.

**Good**: < 500ms

**Acceptable**: 500ms - 1500ms

**Poor**: > 1500ms

Use our Bulk Checker to measure latency for up to 500 proxies simultaneously.

2. Uptime and Reliability

A proxy that frequently goes offline is useless for continuous operations.

**What to measure**:

3. Anonymity Level

Proxies fall into three anonymity categories:

Elite (High Anonymous)

Anonymous

Transparent

4. IP Reputation

Some IPs are flagged due to previous abuse:

**Check for**:

Testing Process

Step 1: Collect Your Proxies

Gather proxy list in IP:PORT format or with authentication.

Step 2: Use Bulk Checker

Step 3: Analyze Results

Export working proxies and sort by:

Step 4: Monitor Over Time

Proxy quality changes. Set up regular checks to maintain a healthy pool.

Quality Scoring Formula

We calculate quality scores using:

Score = (Anonymity × 0.4) + (Speed × 0.3) + (Reliability × 0.3)
