What is load time, and how does OnCrawl measure it?

Updated over a week ago

What is load time?

Load time is the time it takes to display a web page.

Measuring load time is important in SEO and improvements can make a difference for your website's user experience and for page performance. For mobile sites, page speed is also a minor ranking factor.

How does OnCrawl measure load time?

OnCrawl measures the TTLB (time to last byte).

This means the time starts when our crawler sends the request for the URL, and doesn't stop until it has received the last byte of information for the page from your server.

Since information transfer can be affected by distance, you may want to take the following information into account:

  • Our servers are located in Belgium.

  • Our fetchers are geolocated at Google, in Mountain View, CA, USA.

By default, like Google does, our fetchers request pages in their English language version. (This affects you if you automatically redirect visitors by language.)

Where can you find statistics on load time in OnCrawl?

It is used in OnCrawl as a metric in the Crawl Report, on the Payload dashboard, to create charts to answer questions like the following:

  • What is my site's average page load time?

  • How is load time distributed across my entire site?

  • Does load time vary from page group to page group?

  • Does load time vary by page depth?
