@klaviyo While we don’t have the fastest website, the Klaviyo plugin alone drops us from a C to an E on gtmetrix. Time to interactive goes from 2.9s to 7.5, and the speed index goes from 1.6s to 4.3s. Total blocking time goes from 317ms to 437ms. Regardless of whether they’re user-perceived speed issues, these are significant speed issues that the automated tools which determine page ranking use. Klaviyo needs to address this.
@klaviyo that’s not a useful or sufficient answer. Please see:

Google uses page speed to determine search and ad placement / rank. They recommend using Lighthouse of Pagespeed Insights to check – which means that is what they’re using to determine the site speed. This means that using Klaviyo fully has the potential to actually hurt page rank on a website. My company just signed up for Klaviyo, but we’re still not active on all of our sites – if Klaviyo is not able to address this, I’ll recommend we leave Klaviyo.
