Commonly used domestic and foreign website speed measurement and performance analysis tools

 

Webmasters, especially SEOers, understand the importance of website access speed to user experience and search engine rankings.

As early as 2012, The Google Gospel of Speed mentioned that for Google's own search results page, every 400 milliseconds delay will cause the overall search volume to drop by 0.44%.

For mobile, it’s even more terrifying: Google’s latest research in 2018 shows that when the mobile page load time increases from 1 second to 3 seconds, the bounce rate will increase by 32%; from 1 second to 5 seconds, the bounce rate will increase. Increase by 90%; if you increase from 1 second to more than 10 seconds, the bounce rate will increase by 123%.

Just this month, Zac updated this news to domestic SEOers: Google is officially launched: page speed affects mobile search rankings,
and Baidu and Google are vigorously promoting MIP and AMP, and they are constantly telling us the importance of website access speed. Sex.

How to make the website faster? This involves many aspects such as network environment, server location and configuration, DNS resolution, CDN, website structure and code optimization. It is not uncomplicated. Ordinary players do not plan to expand today, but the basis for website speed optimization: website speed measurement and performance Analyze and sort out some commonly used websites and tools.

According to ordinary players' own understanding, the concept of "website speed measurement" can be divided into three situations in general:

Test the speed of visiting websites in multiple places

Multi-site speed measurement tools/websites usually test and list the main speed indicators from many monitoring points to the website (such as analysis time, connection time, download speed, etc.) at the same time. Generally, they are not used to detect website code and server performance optimization. Rather, it is mainly used to purchase servers/VPS, server/CDN network speed investigation in various places, and CDN deployment.

• 17ce (domestic website)

  • 60+ domestic and Hong Kong monitoring points for domestic speed test to access the site around
  • Provide multi-dimensional speed tests such as Get, Ping, Route Tracking, Dns, Cdn, etc.
  • Provide monitoring API (paid)

• Webkaka (domestic website)

  • 60+ domestic monitoring points, 30+ overseas monitoring points, suitable for speed test of visiting websites at home or around the world
  • Provide multi-dimensional speed tests such as Get, ping, route tracking, Dns, etc.
  • Provide website speed diagnosis function

• Sucuri Load Time Tester (Foreign website)

  • 15+ global monitoring stations for global access sites (such as trade website) around the speed test
  • Provide webpage connection time, first byte time, total time and other data

• Dotcom-Tools Website Speed ​​Test (Foreign website)

  • 20+ global monitoring stations for global access sites (such as trade website) around the speed test
  • Provide two (first and repeated visits) page loading speed, and you can view detailed information by node

Test and analyze website speed performance

Website performance testing tools/websites, some can also test the speed of visiting the website locally or at a single monitoring point , but its main function is to conduct a full range of code and deployment detection on the website, and give scores and related optimization suggestions according to certain rules .

• YSlow (browser plugin)

  • A website performance detection plugin provided by Yahoo based on 23 indicators that affect website speed summarized by the official team
  • Calculate the performance indicators of all aspects of the page, and give scores and specific optimization suggestions according to YSlow or user-defined rules
  • Support Firefox, Chrome, Safari, Opera and other kernel browsers
  • This is a browser plug-in, the analysis of the corresponding webpage is based on the local visit

• PageSpeed ​​Insights (Google Online Tools/Outside the Wall)

  • PageSpeed ​​Insights is one of Google’s web performance optimization tools, similar to YSlow
  • The mobile terminal and the PC terminal respectively give analysis reports and optimization suggestions
  • PageSpeed ​​Insights service is provided online (it is a web page)

• GTmetrix (foreign website)

  • GTmetrix can be regarded as an enhanced version of YSlow+PageSpeed ​​Insights. The scores and analysis reports of the two are given separately
  • 7 foreign monitoring points (not optional)
  • It will also provide page load Waterfall and speed information
  • Will save historical speed measurement information by URL and compare, view and download at any time

• Pingdom (Foreign website)

  • Similar to GTmetrix, page performance scores and recommendations are based on PageSpeed
  • 4 foreign monitoring points (optional)

• WebPageTest (foreign website)

  • According to region and equipment breakdown, there are nearly 100 monitoring points worldwide (including China)
  • Unfortunately, only a single point of speed measurement can be performed. There are Waterfall and speed indicators, but there are no relevant scores and optimization suggestions.

Track the speed of real visitors

Whether it’s multi-site speed testing or performance analysis, it is often used as a reference for server/CDN selection and website code optimization. After the website deployment, code optimization is completed and online, we will face a soul torture:

What is the speed of visitors from all over the world visiting my website?

Tracking, disassembling and analyzing the visit speed of real visitors to the website, and then performing targeted optimization, is an essential part of website speed optimization.

• Google Analytics (GA)

  • Website speed analysis is a built-in function of GA. If GA is used as a website statistics tool, there is no additional deployment cost.
  • The tracking dimensions are comprehensive: server connection time, server response time, web page load time, web page download time, domain name query time, redirect time, etc.
  • Deeply integrated with other GA visitor data. For example: disassemble visitor's access speed from different dimensions such as country, browser, or website page.
  • GA website speed tracking is sampled data, and the average player's sampling rate is about 1% according to his own observation: there will be about 100 sampled data for 10,000 visitors in the same period.

If the number of visitors to the website is not enough to support effective speed analysis at a sampling rate of about 1% in GA, you can try to find other statistical tools or independently develop related functions. But having said that, it is also debatable whether it is necessary to track the speed of real visitors in this case.
