Prioritize visible content. Screenshot in google page speed is different from the original page.

[winiar]

Hello, I have question about thumbnail in google page speed.

Is the appearance of the thumbnail related somehow with "Prioritize visible content" and server response time? Because I do not know why screenshot taken by google page speed is different from the original page. For example icons are not in good spot on screenshot but in all browsers it looks ok. How fast google take screen shot, can it be taken before all page is loaded with css, js etc?

Greetings!

I suspect there's a time-out where it takes it's picture by a certain time if you have a REALLY slow site. It's supposed to take the picture after the browser signals the page has loaded.

How slow is it?

URL?

I think it is not slow site. Here you go a url:

@Rick Steinwand, any ideas?

Tu web no es lenta pero si tu servidor, lo que dice Google es que tu servidor esta tardando en procesar el HTML inicial ( Waiting TTFB 683.19ms). Tienes que tratar de acelerar TTFB.

PageSpeed realiza las captura de pantalla en el segundo 1 (1000ms)

I suspect you have something that is browser/device specific.

You should be able to test with iPhone or other mobile device using Opera Mobile Emulator or online Browser tests like this: https://www.webpagetest.org/result/170104_XV_DG4W/

Last I heard, PSI uses a screen width of 330px like the old iPhones so make sure your page can do that width.

Thanks for advice I will try check in more devices but in desktop dimension.

Issue with visible content can be made by our slider (visible only in desktop), so also I will check it.

What is the width of desktop devices on PSI? PSI's screenshots on mobile is ok but it is not look good on desktop.
