A PageSpeed Insights Checker enables you to dive in and explore web page speed and user experience of a website. Speed reports are used by website owners, developers, bloggers and SEO specialists for assessing speed of the website, delayed interaction with the website and unexpected movement of the layout. Google's PageSpeed Insights offers mobile and the desktop assessments, performance measurements and how to improve. Also presenting is Free SEO Pro's PageSpeed Insights Checker page. Knowing these results can enable you to prioritize on sensible modifications instead of simply speculating your site seems sluggish.
A website speed checker measures how long a webpage takes to load and how smoothly different actions are performed on a page. Both controlled data tests, and the available real user experience data, are used within Google's PageSpeed Insights.
Laboratory result information allows problems to be diagnosed under laboratory conditions. Field data is reported based on the experiences of qualified Chrome users during a recent reporting period.
The two sources provide answers to different questions. A lab test can be used to explore technical causes, and field data lets you know how visitors have actually experienced a page.
The evaluations done with a mobile device could be different than the evaluations done with a desktop device due to the different processing abilities, mobile devices and network conditions.
An optimally performing page on a high-powered computer could be problematic on a slower smartphone.
Always examine the scores for the device category that corresponds to your visitors and don't rely on a single score.
Google's PageSpeed Insights combines the use of Lighthouse for lab analysis with the Chrome User Experience Report if they have enough field data.
Lighthouse explores a page in a controlled environment, generating diagnostic data. Real user data represents diverse devices, connections and browsing behavior.
The underlying integration for SEO tests that is provided by Free SEO Pro must be verified separately. Its name as a tool is not enough to get an idea of the Google services, metrics, or reports it already offers.
Core Web Vitals are metrics that highlight three crucial areas of user experience.
Largest Contentful Paint (LCP): Measures when the largest element of your content that's visible to the user is done rendering.
- Interaction to Next Paint (INP): Measures how quickly the webpage is able to respond to user interaction.
Cumulative Layout Shift (CLS): It quantifies unforeseen movements.
Google sets their good thresholds as below 2.5 seconds for LCP and below 200 milliseconds for INP at the 75th percentile of visits; and less than or equal to 0.1 for CLS.
These measurements represent various issues. An improvement in one doesn't automatically mean improvement in another.
Start on a public web page you wish to explore.
First go to the PageSpeed Insights Checker page.
2. If there is an interface for entering a URL, locate it.
3. Type the full address of the webpage (don't forget to include the https:// prefix).
4. Check for any visible device or testing options.
5. Start the analysis using the available control.
6. Review measurements and recommendations made.
If both mobile and desktop are supported, compare mobile and desktop results #7.
Note down crucial information before making any alterations to your website.
9. Re-test once improvements made.
These are the steps involved in a basic website performance testing process. The exact controls and fields in free SEO Pro's report need verification while running.
If you want something that you can see for yourself then Google PageSpeed Insights will work.
Suppose that a web site owner is given the following performance report:
|
Measurement |
Example result |
|---|---|

Mobile performance score |
42 |
|
Largest Contentful Paint |
5.8 seconds |
|
Interactions to Next Paint |
180 milliseconds |
|
Cumulative Layout Shift |
0.24 |
Numbers are speculative values provided and not created by Free SEO Pro.
The slow LCP indicates that content that is important to the user is not being seen within an adequate timeframe. CLS indicates that elements are moving in places that they are not meant to.
The owner looks out for: too large images, slow loading fonts & advertising containers with no declared sizes.
The owner makes changes and retests and checks both laboratory measurements and available field data.
Judging by laboratory ratings and numbers is good but doesn't mean real users' metrics will necessarily improve right away.
Lighthouse scores 0-100, based on weight.
The general range of scores is as follows: 90-100 (good); 50-89 (needs improvement); and less than 50 (poor).
The observed score represents the lab measurements. This isn't a direct Google ranking indicator, so it won't necessarily guarantee that visitors will be happy online.
This slow LCP typically means you have a combination of large images, slow server response times, render blocking resources or slow rendering of content.
Prior to selecting an optimization, research the purine your LCP is composed of.
When users are tapping, clicking, or typing around the page, they may find that the page works slowly, meaning that it has a high INP.
Potential causes would be heavy JavaScript execution and tasks taking too long to be completed on the main thread.
A common occurrence of high CLS is when images, ads or embedded content appear or load into areas that were not set aside for them.
If the proper dimensions and fixed layouts are provided, it is possible to keep the unexpected movement to a minimum.
See how it performs before launching a site, or redesigning key pages, or adding annoying ad scripts or plugins.
The slow product pages can be analysed by online stores. Bloggers can review the loading of articles. Developers can check whether the performance is better or worse pre and post-deployment.
Periodic testing can be used to identify regressions, particularly if third party scripts are changing or loads of media files are changing.
Performance testing can also be used in the process of usability testing, though it is not a replacement for accessibility testing, functional testing and real visitor feedback.
One error is to only consider the total score. Errors in interaction or for specific users may be present in a score of 95.
The other is the assumption that lab results equal real visitors' results. These measurements are taken by various collecting techniques.
If an analysis doesn't work, check the URL is correct, available for public access and not authentication or server restricted.
Check again when temporary problems with the servers have resolved. When performing multiple runs, don't make significant changes to your test after a single "strange" result.
Performance reports discover potential issues but by themselves do not fix websites.
Because of network conditions, the response time of the servers and the environment of the tests, the score may be different across tests.
There are some sites that do not have adequate real user data. This does not always indicate that the web site is faulty.
According to Google's official documentation, field measurements are calculated across a 28-day moving window, and can not be available when the samples are not eligible (meaning too few samples).
Google for Developers
A fast website doesn't necessarily mean it doesn't have accessibility, content or indexing issues. Improving speeds should be a part of a website makeover.
Free SEO Pro has a Page Speed Checker page to investigate loading of other websites.
Its Server Status Checker can be useful to research HTTP claims issues and the Website Screenshot Generator applies to when checking page layouts.
Before making technical changes, familiarise yourself with each metric using PageSpeed Insights official documentation.
It is a tool used for optimizing the performance of a web site and potential loading and usability issues are identified. The measure(s) used will vary based on the service and implementation.
Use a speed checker tool that supports your website, initiate the checker, and view the results. Google's official PageSpeed Insights has documented test facility.
Lighthouse scores in the range of 90-100 are considered good. However, real visitor measurements and individual performance problems also should be taken into account.
Mobile testing can emulate the speed of the mobile device and connection used. Large images, javaScript processing, and complex layouts can have an impact on mobile that may be more noticeable than on the desktop.
LCP is a measure of when the largest above-the-fold content element is rendered. The threshold that Google recommends is the 75th percentile being 2.5 seconds or less.
Cumulative Layout Shift (CLS) gauges the movement of content which has appeared on the screen. Google's recommended CLS value is 0.1 or below.
Interaction to Next Paint quantifies responsiveness when users interact. Google's good threshold is 200 milliseconds or less at the 75th percentile.
Conditions of the tests, reactions of the servers, availability of resources and the content of the pages may vary from one test run to another. Investigate repeated measures and look for consistent patterns to determine what should be changed.
While a good website UX can indirectly help improve the quality of the website, a strong rank doesn't ensure better positioning, website indexing, traffic or authorisation of ads on Google.
Google's official tool PageSpeed Insights allows you to analyse both mobile and desktop. You cannot assume the same functionality when examining free SEO Pro's available device options—you should check them outright.
It is necessary to have enough samples to be eligible to be included in the Chrome user experience report. Limited qualifying traffic on new websites and pages may lack data.
Yes. It is recommended that images be of the correct size and be optimized to reduce the data sent and rendering delay if images are too large or are not optimized. Using the proper size and compression as well as modern image formats may help.
Yes. Intense JavaScript processing can cause delays in rendering and interactions. When investigating slow pages look for unnecessary scripts, long tasks and 3rd party resources.
No. A top-notch lab rating does not promise that all clientele will have a top-notch performance. The issues of accessibility, usability and functionality, as well as actual conditions in the real world, must be considered separately.
Highlight areas of major issues, prioritize changes and retest. Look at the mobile and desktop results, and then observe if a real user measurement is available; this data points to improvements in the longer term.
