  • Migrating from Shopify to custom coded site. What should we do to maintain SEO and ranking?

  • 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
