Website Speed Test

We're on TelegramFound an error?
A helpful service that allows you to visually assess how quickly your website is loaded in a user's browser. The tool will tell you about errors on a page of your website.

Why is Site Speed Checking Important?

A slow-loading website impacts behavioral factors and search engine rankings. Speed affects:

  • Search Engine Rankings. Search engines analyze page quality and rank the most suitable pages based on several parameters. For example, Google has Page Experience, a set of requirements for websites, including loading speed.
  • User Experience. If a page loads slowly, users are likely to close the tab, resulting in lost traffic and conversions. Search engines consider behavioral factors, so poor user experience ultimately leads to search engine issues.

How is Loading Speed Measured?

Tools measure loading speed based on several parameters:

  • FCP (First Contentful Paint) - time until visible content loads.
  • Speed Index - assesses how quickly visual elements on the page become visible to users during loading.
  • Total Blocking Time - the time after visible content (FCP) loads when the website is unresponsive, and users can't interact with it.
  • Time to Load Sufficient Content - the time it takes for content to appear on the first screen.
  • Time to Interactive - how quickly a page responds under load. This metric identifies situations where a page appears interactive but is not functioning properly.
  • CLS (Cumulative Layout Shift) - a metric measuring the stability of the page's layout. It evaluates the magnitude of unexpected shifts in page elements during loading.

The service lets you check site speed and improve performance metrics. Beneath the numerical parameter summary, there's a task list. Recommendations are marked with an exclamation point, including explanations, links to relevant articles, and a preliminary efficiency assessment—how many kilobytes you can save by following the advice.

Site speed checking is free and allows analysis on desktop and mobile devices.

How to Speed Up Your Website?

To speed up website loading, combine various methods: code minification, gzip or brotli compression, optimizing the top part of the page, content compression with minimal quality loss, and setting up caching. Some projects might benefit from Yandex Turbo pages or Google's AMP.
