Why does Avg. Page Load Time is Zero on Google Analytics?

Question

I have recently connected to GA to track usage and my site view would less than 1000 views per day. I would like to see my site "Avg. Page Load Time" but it is always showing zero. What needs to done to get Avg. Page Load Time ?

I have referred How to set up page speed logging for google analytics in analytics.js but i don't have permission to Modify the GA code in the site. Is there any other option to get Avg. Page Load Time ?

Question:

Please see below that got Avg. Page Load Time for first landing page but remaining pages still 0 and my question is When will get Avg. Page Load Time for remaining pages(Please give me example to any one page) ?

Answer 1

The best solution to obtain a statistically significant value (or as much as possible in Google Analytics) is that of the link you entered.

10.000 page views should surely show data even with the default setting (1%).

To understand if the data you will be looking at makes sense, create a custom report with dimension Browser and metrics Avg Page Load Time (sec) and Page Load sample like this:

In this way you see if the sample is low, so the data is not very reliable.

This is the example for your second question (directly from Demo Account of Google Merchandise Store):

About your new screenshot: if you try to create a custom report with Avg. Page Load Time and Page Load Sample you will see that for that pages (with Avg. Page Load Time equals 0) the sample is 0, so the page load time cannot be calculated.
