How It Works

TrafficPeek provides website traffic data through two sources:

1. Tranco List (Top 1 Million Sites)

• Uses the Tranco List - a research-based domain ranking combining Alexa, Majestic, Umbrella, and Quantcast data
• Provides real global rankings for the top 1 million websites
• Traffic estimates calibrated against SimilarWeb data

2. SimilarWeb API (Any Website)

• Add your free RapidAPI key to get real SimilarWeb data for any website
• Includes accurate monthly visits, bounce rate, pages per visit, and more
• Works for sites outside the top 1 million

Note: For sites outside the Tranco top 1M, you'll need a SimilarWeb API key to see traffic data.

Getting Real Traffic Data

Add a free RapidAPI key to get real SimilarWeb data for any website (including sites outside the top 1M).

Setup Instructions

1. Go to the SimilarWeb Insights API on RapidAPI:

   👉 similarweb-insights.p.rapidapi.com

2. Subscribe to the free tier (click "Subscribe to Test")

3. Copy your API key from the "X-RapidAPI-Key" field

4. Open TrafficPeek extension and click the ⚙️ settings icon

5. Paste your API key and save

Note: The free tier includes 100 requests/month. TrafficPeek will fall back to Tranco data for top 1M sites if you run out.
