It is normal to see a small fluctuation in your scores over a short period of time. These fluctuations can be caused by variations in server response, domain lookup, and asset loading times. How quickly assets load can be affected by other programs running simultaneously on the device that is trying to access your site.
If you see large score fluctuations over a long period of time this can be attributed to Google making adjustments to their scoring system.
What should I do with unused JS, CSS, and Google Fonts?
If you added the unused JS, CSS, or Google fonts to your site, you can remove them wherever you originally added them.
When checking Web Vitals, your report might reference JS and CSS that can be removed. Typically, this is not referencing the code you have added, but is referencing default code that cannot be changed or removed.
Can I access the JS and CSS source files?
You cannot access JS and CSS source files because they are a core part of the platform.
Google sent me an email saying Core Web Vitals INP issues were detected on my site. What does this mean?
INP is an existing metric that was previously not officially measured, though Google has recently announced it will be replacing the FID metric in March 2024. The INP score will not impact CWV until March 2024. However, in preparation for this transition, Google has started to inform site owners when INP issues are detected.
Prior to the announcement from Google, Website Builder had already started addressing this metric. As a result many sites already score well on INP, though we are continuing to optimize it.
We are continuing to learn about INP and identifying the optimal practices for both backend operations and site creators. We will update you on what best practices you can put in place are as we learn more. In the interim, if you receive a notice from Google reporting your site has INP issues, please review your site to ensure it is following the current best practices (for detailed information on best practices, see Optimize Your Site for Core Web Vitals).
Rest assured, Website Builder is actively working on optimizing this score and we are confident we will be ready for the official launch in March 2024. If you have any concerns about your INP score before that time, we recommend consulting with an SEO expert for further assistance.
How do I remove render-blocking resources?
If you added JS to the site head, it can block your page content from loading while the JS renders. For this reason, we recommend moving your JS to the body and adding either async or defer keywords. Using async tells the browser to load the script and page contents at the same time. Using defer tells the browser to run the script after the page contents have loaded.
What are the best templates for page speed?
All templates are well optimized, but the most recent templates have been optimized for current guidelines. To determine which templates were most recently released, look for the orange New icon on the template.
Should I add scripts to the head or body?
We recommend adding scripts to the body. If your scripts are in the head, they will have to parse before any HTML or CSS can load. This can cause a delay in LCP and FID.
Why is my mobile score lower than my desktop score?
In general, mobile devices are slower than desktop computers because they rely on data. For example, a video loads faster on a desktop computer than it would on a mobile phone using data.
