Let me tell you real life story.

Passengers at Houston airport would get off the plane, take a quick 1 min walk to the baggage claim & then wait 7 mins to get their bags. The total time to collect bags was 8 minutes.

  • a 1 minute brisk walk,
  • & 7 minutes twiddling their thumbs waiting for the bags to arrive.

The problem was, that because everybody felt, that they were waiting an unnecessarily long 7 minutes for the bags, the airport got inundated in complaints about poor service.

So what did they do?

They couldn’t get the bags from the plane to the bag collection any quicker

So they decided to move the arrival gate 6X further away from the bag collection point.

Now people had a 6 min walk instead of a 1 min walk.

Instead of waiting 7 mins for the bags to arrive they were now only waiting 2 mins, because the rest of the time they were busy walking.

The total time to get your bags was still the same at 8 minutes.

Guess what?

All the bad service complaints stopped because people felt that they weren’t waiting, even though it took the exact same amount of time.

Perception is vital & it’s even more important with website speed.

If people feel that your website has loaded (even if it hasn’t) and they can start engaging with it, they will hang around longer & buy more.

With that in mind,

These are the Core Parts To a Website’s Load Time

  • Perceived Load Time (which we’ve just talked about)
  • Full Load Time
  • Returning Visitors Load Time
  • Mobile vs Desktop Load Time

Let me unpack those a little.

Perceived Load Time

When a new visitor lands on your website you want them to get the perception that it’s a fast website.

You want to give them something to do, while the rest of your website loads.

A bit like in my story, in that while people were busy walking, the airport was busy moving the bags in the background, so people didn’t feel like they were waiting.

Full Load Time

This is the time it takes for the full website to load.

All the components, functionality & features are fully rendered.

Unfortunately, many websites force their visitors to wait it to fully load, when in fact, they could have loaded it in sections & given the visitor something to do while this happens in the background.

Load Time for Returning Visitors

This is the time it takes for the website to load for a person who has returned to the website.

Remember that when a person visits a website the data is transferred from the server to the person’s device & stored in their browser.

What caching does, is that if a visitor returns to the website, it checks if anything is different & if not, it shows this stored copy that’s in the visitors browser, instead of fetching the entire page from the server again (which takes time). If there are changes since they last visited, it just grabs the changes instead of the entire page.

Using advanced caching technology it is possible to give repeat visitors a 90%+ improvement on their experience!

Mobile & Desktop Load Times

We’ve already covered this in another section but you must always keep in mind that they are often completely different!

Now that you understand the various parts to a website’s load time it will help you optimize each them.
