The Best Tools for Measuring Page Speed
If you’re finding that your website is super slow, especially on mobile, then chances are that it’s not just you that’s getting annoyed – your customers will be too.
Monitoring how fast your important webpages are over time can really help improve your search engine rankings, conversions and revenue for your business.
So, what are the page speed best tools? Let’s take a look at some of the top tools I recommend below…
Why is page speed important?
Page speed is really important for a few reasons:
- Google’s algorithm considers how fast pages are when assessing where to rank certain webpages for specific keywords. A faster website that your competitors could mean the difference in one position, but that one position could mean the difference of a 20% CTR or a 34% CTR from search results. No one wants to turn that level of traffic.
- Mobile devices have exploded in use over the past decade or so, and it’s likely to see future growth too. With mobile device users not always being connected to WIFI connection, it’s really important that your webpages are optimised to perform as fast a possible for 3G and 4G connections.
- Brand awareness and loyalty. If potential customers are arriving to your website and they are repeatedly experiencing a very slow page speed, then this could damage your brand and potential for future repeat purchases. High bounce rates can lead to your potential customers to leave your website and visit a competitor website.
The best tools for monitoring page speed
Here are the page speed monitoring tools we regularly use at QueryClick to keep an eye on performance.
Plus, a few extra tools that could bring a lot of additional value to your business.
This is a staple page speed tool that I’ve been using for a few years now.
GTMetrix is great for:
- Monitoring page speed metrics over time, daily, weekly or monthly
- Creating email alerts for page speed budgeting issues
- Setting testing locations e.g. London, Sydney, Tokyo
- Test for mobile or desktop with most used browser types available
- Connection type e.g. 3G or Broadband connection
Google has not long ago launched Core Web Vitals as part of their overall Page Experience metrics.
GTMetrix have also updated their tool to help us all monitoring Core Web Vital metrics which include:
- LCP (Largest Contentful Paint) – which measures loading and how fast your page appears visibly load
- TBT (Total Blocking Time) – Interactivity of the website and how usable your page is while loading
- CLS (Cumulative Layout Shift) – measures visual stability of elements on the page when a webpage is loading
GTMetrix is great for us to share results of our page speed performance optimisations with our clients. Whether it be a CMS migration testing UAT or PROD environments and testing in live after launch of sprint cycles.
GTMetrix is very reliable and hasn’t let us down to date. I’d highly recommend the tool if you’re looking to start tracking performance. The monthly cost is reasonable and in my opinion, definitely worth it.
Google Page Speed Insights
Another page speed tool that we use sporadically alongside GTMetrix is Google’s tool, Page Speed Insights.
Page Speed Insights is great for:
- quick sense checks
- benchmarking against your competitors. Particularly great for a top level view and snapshot of performance.
The way we use Google Page Speed Insights is via testing on a browser or API data to a Google Sheet.
Using the browser version is great, however only gives you a view of just one page. Using the API can help you collate multiple page speed metric results for a bulk set of URLs. This helps us to track performance for some of our clients.
A great use of this data can be to display page speed results via Google Data Studio into a Dashboard. A very cost effective way of tracking page speed performance over time. Only downside is that there aren’t options for users to customise tests by certain factors such as location, browser or connection types.
This tool helps our Technical SEO team here at QueryClick to sense check the specific offending files and requests being flagged. We sense check page speed metrics, such as LCP and CLS, in Chrome browser to identify performance issues and where they sit.
Usually by clicking on ‘View Original Trace’ or ‘Treemap’ allows us to access this information which splits out certain file types during the load of a page. Certain page speed metrics are flagged within this view in Google Chrome allow us to see when metrics are triggered.
This tool is great for when we are speaking with your performance-based stakeholders e.g. development teams and third-party tagging solution providers.
CrUX (Chrome UX Report) on Google Data Studio
Using this method we are able to share some great aggregated performance metrics for our clients, and potentially you, for real users of your website.
It’s very easy to set up and doesn’t require much effort (if any) to maintain the report. Simply open and check the dashboard over time.
With a lot of tools, including GTMetrix, the data is only “Lab” data. A Lab report is a simulated page speed test, whereas RUM (Real User Monitoring) is data collected from a real users.
The benefit here is that you get to see an aggregated view of all users of your website, which can be a plus point if you want a top level view of performance.
Lab data reports are great for conversations with developers. RUM data reports are great for marketing and performance based stakeholder conversations.
If you’re looking to get started building a Google Data Studio Dashboard using CrUX data, I recommend reading this article. It’s a simply process, basically putting in your domain and let Google Data Studio create the dashboard. Then you’re done.
