  • A PageSpeed insight report, but for every page in your domain
    Trust neither. The most optimal option I've found is webpagetest.org Its been quite handy lately. This tool does look interesting. Source: 11 months ago
  • How are you all accurately checking your website load time? Not sure PageSpeedInsights is very helpful.
    Webpagetest.org is another. Pagespeedinsights and lighthouse are great for identifying page load issues to fix, but actual page load times will always vary between the user and your web server. Universal analytics has some page load timings but that's going away soon and nothing afaik is in GA4. I've seen an example of building a page load timer in tag manager and dumping the results into an event. Source: about 1 year ago
  • Extreme confusing over Speed Index results -- webpagetest.org
    So I am working on rebuilding our company's site with a new stack. I am running tests using webpagetest.org, and I am having trouble fully understanding the speed index results as well as the film strip view. The page renders quite fast everywhere I test it. Google Lighthouse shows it in the 90s + for performance score, however when I test the page on webpagetest, I get load times of 77 seconds (NOT MS) which is... Source: about 1 year ago
  • Does anyone else experience pure ecstasy when they get 100 on Lighthouse? 😩
    Webpagetest.org is great, and checking OP's site they have done an incredible job, I don't think I have ever made or seen an Ecom site this slick. Super clean waterfall view. Source: about 1 year ago
  • Performance scores for Google Lighthouse/Insights seem to be very inaccurate
    Thanks for the recommendation regarding webpagetest.org, another user made a similar recommendation so I will check it out. Source: about 1 year ago

  • Migrating from Shopify to custom coded site. What should we do to maintain SEO and ranking?
    Audit the heck out of the new platform. Shopify is a bit rigid, sure, but it's also quite optimized and they have solid performance requirements. Your new site should be equally good, at least when tested with: PageSpeed Insights / Lighthouse, Google Rich Results tester (for structured data), Ahrefs (for site health), Pentest-Tools.com Website vulnerability scanner (for site security), WAVE (for accessibility),...

  • WP Rocket - literally no change to mobile score, any ideas?
    Hey, I can't get enough of repeating it. Stop using GTMetrix unless you have PRO plan and can test as mobile and with your website/visitors location. Try instead speedvitals or yellowlab that are far superiors tools in their free version (and even compared to GTMetrix PRO for some insights/features). Source: about 1 year ago
  • Why it’s a good idea to have a website
    Code quality (importance score 6/10): verify with https://yellowlab.tools/ and with https://www.dareboost.com/en – the higher the score, the easier the site will be to maintain and the fewer technical issues it has, in general. Source: about 3 years ago
