Content Type Analysis

The Content Type analysis provides detailed insights into the types of content served by a website, focusing on their distribution, size, load times, and HTTP status codes.

Key Metrics

Section titled “Key Metrics”
  • Total URLs: Counts the number of requests per content type (e.g., Images, HTML, JS, CSS).
  • Total Size: Summarizes the cumulative size of each content type, highlighting resource-heavy categories.
  • Total Time: Aggregates the time taken to load each content type, giving an overview of performance.
  • Average Time: Provides the average load time per content type, helping identify potential bottlenecks.
  • Status Codes: Displays the distribution of HTTP status codes (2xx, 3xx, 4xx) for each content type, pinpointing issues like redirects (3xx) and errors (4xx).

Sample Results

The analyzer generates detailed tables showing content type distribution:

These tables help identify:

  • Resources consuming the most bandwidth (Images: 18MB)
  • Content types with the longest load times (HTML: 4s total, Image files with 185ms average)
  • The distribution of content types across the website
  • Content types with error responses (JSON with a 404 error)

In the future, we want to add cache settings analysis to this section and provide statistics and recommendations from the caching area. A properly set content cache (especially for assets) has a significant impact on real browsing speed.
