PageSpeed update: Javascript redirects, Accept-Language

[Daniel Bathgate]

Greetings Insights users,

We are rolling out a new release of the online Pagespeed Insights tool. Notable changes include:

• Proper handling of client side (Javascript) redirects.
• Redirects triggered by scripts will now be scored in "Avoid landing page redirects", where previously they were erroneously ignored.
• This also fixes a bug where "Prioritize visible content" and "Eliminate render-blocking JavaScript and CSS in above-the-fold content" did not properly score pages preceded by a javascript redirect.
• Localized versions of Insights will now send a "Accept-Language" header with the language of the UI.
• For example, loading Google while viewing the Spanish frontend will analyse the Spanish version of Google. Example: http://developers.google.com/speed/pagespeed/insights/?hl=es&url=google.com

Additionally, Insights now has a responsive mobile design - check it out on a mobile device for quick tests.

Hi Daniel!,

excellent job. 

Like we have "tested", in my web was located "Avoid landing page redirects" correctly and  causes "Prioritize visible content" with a lot of js code that i have moved to their correct  position.

I have tested responsive APP and performs perfectly (Xperia S 720p). 

Best regards and congratulations for the good job.

Miguel.

Hello, Daniel!

FYI: The PageSpeed Insights UI has a design bug. You can reproduce it this way:

• Resize you browser window to 1,024 x 768 px.
• Run a test.
• Scroll down and everything is fine.
• Now open one of the expandable sections, preferrably one below the top.
• Scroll down again and you will see that the preview image (both mobile and desktop) will skip from the right to the left and cover the text area.

Regards, Thomas
