As you are already aware, Core Web Vitals will become an official ranking factor in May 2021.
I am in love with Webflow and I am ready to shift to it, but I have tested a lot of Webflow websites (Themes, Community websites, cloneables) and almost 90% of them doesn’t pass the web vitals test, which made me really worried.
Hi all! I find websites built with webflow will do much better in tests than those built with other builders like squarespace or even wordpress if you use a lot of plug-ins. If you are able to custom code build then things will be different but I have found webflow sites to be the fastest to load and have the best structure (since you build the structure yourself).
