Do you want to improve your website’s performance?
While there are tools to track performance metrics, many are lacking the features you need to accurately collect and utilize your website’s performance data.
So, let’s learn more about the key performance metrics you need to analyze to keep your website running at peak performance and help improve your rankings.
You’ll also find out how DebugBear can help you track historical changes, see the effects of changes to your website’s performance immediately, and get additional insights beyond what Google has to offer.
Core Web Vitals (CWV) are performance metrics that use real user experience data to measure the speed, responsiveness, and visual stability of your website.
The following three metrics make up your website’s Core Web Vitals:
To meet Core Web Vitals, your webpage must have an LCP within 2.5 seconds, FID of 100 milliseconds or less, and a CLS score of 0.1 or less.
In 2020, Google announced that page experience signals, as a whole, would become a part of Google Search ranking factors.
After it was launched, Google’s John Mueller confirmed that it was more than just a “tie-breaker” metric.
“It is a ranking factor, and it’s more than a tie-breaker, but it also doesn’t replace relevance.
Depending on the sites you work on, you might notice it more, or you might notice it less.
As an SEO, a part of your role is to take all of the possible optimizations and figure out which ones are worth spending time on.
Any SEO tool will spit out 10s or 100s of ‘recommendations,’ most of those are going to be irrelevant to your site’s visibility in search.
Finding the items that make sense to work on takes experience.”
Further, in a Core Web Vitals Q&A, Mueller states that Core Web Vitals are not binary.
You may see ranking improvements as a website moves just from “needs improvement” to “good” in LCP, FID, and/or CLS.
Google offers three ways to track your website’s Core Web Vitals:
These tools can give you some insight into your website’s performance.
On their own, they each have inherent flaws that can make it difficult to accurately track the user experience data you really want.
In short, if you’re using only Google’s native tools for CWV troubleshooting, you may be missing key information that helps you drill down and make effective improvements to your website.
Google Search Console doesn’t show Core Web Vitals issues by individual URL right out of the gate.
Instead, it shows issues by groups of URLs.
This makes it difficult to drill down to specific pages that require change.
The reason, according to Search Console Help, is as follows:
“The report is not designed to find the status of a specific URL, but rather to see your site’s performance as a whole, and troubleshoot issues affecting multiple pages on your site.
If you want to see performance data about a specific URL, use an external test. Although you can drill down on status and issue and see specific affected URLs, finding a given URL using the Core Web Vitals report can be challenging.”
Metrics provided by the Chrome User Experience Report don’t give insights for specific URLs either.
“Site owners that want more detailed (URL level resolution) analysis and insight into their site performance and can use the same APIs to gather detailed real user measurement (RUM) data for their own origins.”
The Pagespeed Insights Tool offers both field and lab data for your website’s core web vitals.
Field data represents your actual user’s experience over the last 28 days.
Lab data is collected in a controlled environment with predefined settings for the devices and network.
With two different sources of data, which one is the one you should trust to better optimize your website’s performance?
For a more detailed analysis and clear understanding of your Core Web Vitals, Google recommends:
It is clear that Google’s tools provide the framework for data collection.
