Page Speed Bulk Checker

Overview

Page Speed Bulk Checker is an Apify actor that measures page load performance metrics for multiple URLs simultaneously. It captures Time to First Byte (TTFB), DOM content loaded time, full page load time, total page size, and the number of HTTP requests made. The actor supports both desktop and mobile device emulation, making it ideal for web performance auditing, benchmarking, and SEO optimization. Results are structured for easy comparison across pages and sites.

Features

• Measure TTFB (Time to First Byte) for server responsiveness
• Track DOM content loaded and full page load times
• Count total HTTP requests per page
• Calculate total transfer size in kilobytes
• Measure DNS lookup, TCP connect, and SSL handshake times
• Mobile and desktop device emulation
• Bulk processing of multiple URLs
• Uses Chrome DevTools Protocol for accurate measurements

Use Cases

• SEO Optimization: Page speed is a ranking factor; identify slow pages to improve
• Performance Benchmarking: Compare load times across your site or against competitors
• Regression Testing: Monitor page speed over time to detect performance degradation
• Mobile Optimization: Compare desktop vs mobile load times
• Web Development: Measure the impact of code changes on page performance

Input Configuration

Parameter	Type	Default	Description
urls	Array	["https://apify.com", "https://anthropic.com"]	URLs to check page speed for
device	String	"desktop"	Device type to emulate (desktop or mobile)

Output Format

Each result includes the URL, TTFB, DOM load time, full load time, DNS lookup time, connect time, SSL handshake time, page size in KB, and request count. Data is stored in the default Apify dataset and can be exported to CSV, JSON, or Excel for reporting.

Integration

Schedule regular performance checks via Apify schedules. Send results to Google Sheets or dashboards via Apify integrations. Use the Apify API to trigger checks from CI/CD pipelines or monitoring systems.

Limitations and Notes

Performance metrics are measured from Apify's data center and may differ from end-user experience in different geographic locations. Results vary between runs due to server load, network conditions, and caching. For reliable benchmarking, run multiple checks and average the results. The actor uses Puppeteer with Chrome and requires at least 2048 MB of memory. Very large or complex pages may take longer to load and measure.
