问题 We have our development page giving correct score on page speed insights. https://developers.google.com/speed/pagespeed/insights/?hl=en&url=https%3A%2F%2Fdev.techtitute.com But our production page always returns scan error: Lighthouse returned error: FAILED_DOCUMENT_REQUEST. Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests.

问题 https://developers.google.com/speed/pagespeed/insights/ On 27th May 2020 I had used page speed where I got a pretty good score for desktop (90+) and for mobile around (85+), but as on 28th May 2020 the metrics seems to drastically changed, I can see the PageSpeed has new version (v6) but no proper release notes are provided here https://developers.google.com/speed/docs/insights/release_notes. Anyone had faced similar issue and found that google pagespeed did undergo certain upgrades then

问题 I'm Brazilian, and I'm starting to make a sports blog. I went to PageSpeed Insights to make an assessment of what I still need to adjust, but the analysis stops at 50% with the following error: "Requests from referer https://www.googleapis.com/ are blocked" What may be the problem? Would it be something simple to solve? 回答1: The main reason people get this issue is that they have a firewall / anti-virus blocking certain requests. If you are using Brave Browser with 'Shields Up' then this is

问题 While checking the website speed at Here It throws this error: Lighthouse returned error: generic :: internal: APP :: 1: Abnormal renderer termination, status = crashed exit_code = 1 Please can anyone tell me how this can be solved and how serious is it? 回答1: Your website has a problem with its SSL certificate. What (I am making an educated guess here) is happening is that Lighthouse is attempting to run the 'redirects to HTTPS' test and is throwing an error within Chrome in 'headless' mode

Why emulated 3g on pagespeed-insights?

阅读更多关于 Why emulated 3g on pagespeed-insights?

问题 As i checked on google, pagespeed measures mobile and desktop sites using "Emulated 3G network". As per some GSMA report from 2016 that 75% or users are on 2G/3G networks. Thats almost 2019 year and many users are on 4G now, so reports are useless. Can someone tell Google that either they should use "No throttling" or add switcher for 4G network. 回答1: Per GSM report for 2017, 71% of Global users are on 2G/3G network. That number drops to 32% for North America and 59% for Europe. While we are

Google Page Speed Drop, says I can save more loading time, even though nothing changed

阅读更多关于 Google Page Speed Drop, says I can save more loading time, even though nothing changed

问题 I'm testing my pagespeed everyday several times. My page often receives a grade between 94 to 98, with the main problems being: Eliminate render-blocking resources - Save 0.33 Defer unused CSS - Save 0.15 s And in Lab data, all values are green. Since yesterday, suddenly page speed has dropped, to about 80-91 range, with the problems being: Eliminate render-blocking resources - Save ~0.33 Defer unused CSS - Save ~0.60 s And it is also saying my First CPU idle is slow ~4,5ms And so is time to

Can Google.com and other heavily trafficked websites get a “fast” rank using Google's PSI v5 API?

阅读更多关于 Can Google.com and other heavily trafficked websites get a “fast” rank using Google's PSI v5 API?

Does using the 90-percentile instead of median score when saying, "based on field data the 'page is slow'" make it impossible for heavily trafficked websites, such as google.com, from ever getting ranked "Fast"? This due to the long tail that occurs when monthly traffic is in the 10M+ ranges? Last time I checked (early Feb. 2018), the Desktop google.com received a 100 Lighthouse synthetic score, which is supposed to be interpreted as "there is little room for improvement," and yet, the page is ranked "slow" because the 90th percentile FCP is way over 3s. Will a page like nytimes.com ever be

Google Page Speed insights. Lighthouse measurement origin

阅读更多关于 Google Page Speed insights. Lighthouse measurement origin

问题 Google provides Speed index for given URL by doing a lighthouse measurement: https://developers.google.com/speed/pagespeed/insights The data differs a lot from my own measurement. Now my guess is for the mobile page test they use some 4G emulation on a machine located in the US while my testet webserver is located in europe. Any idea where to find information on the geo location they perform testing from ? 回答1: Lighthouse uses 'a slow 4G connection'. This choice influences the importance of
