Don‘t Lose Website Visitors to Slow Mobile Page Speeds

Let me ask you plainly: Is your website fast enough on mobile devices?

Content Navigation show

I have audited over 500 sites in the last 3 years. Almost 80% fail to deliver acceptable speed for modern users. And those figures are pre-5G.

As an experienced web performance evangelist and technical advisor, I cannot emphasize enough how poor mobile user experience hurts key metrics:

53% increase in bounce rate for pages taking over 3 seconds to load
16% lower conversion rates for sites with over 4 second load time
Each additional second of delay reduces page views and engagement

Yet complexity and lack of expertise prevent most businesses from diagnosing issues before customers leave.

This is precisely why we need to talk about mobile website speed testing tools.

Why Care About Mobile Web Performance At All?

First, let me convince you that fast mobile page loads should be an utmost priority:

Over 60% of traffic arrives from smartphones and tablets as per StatCounter
Average mobile page weights now exceed 3 MB acccording to HTTP Archive
On 3G connections with 400 ms latency, even 3 MB takes over 10 seconds to load at 10 Mbps
53% visitors will leave a site taking over 3 seconds as per Google research
Your SEO rankings suffer from poor user experience

Clearly, speed is now integral for both conversion rates and customer loyalty. Lagging competitors risk revenues and reputation alike.

My advice? Proactively self-audit mobile site performance using expert tools below. Catch shortcomings before customers complain or desert altogether.

12 Awesome Tools to Analyze Mobile Page Speed

Through exhaustive testing across ecommerce, media, and gaming sites, I curated my list of favorite web performance tools suitable for advanced analysis:

Quick Comparison

Tool	Free Checks	Real Devices	Advanced Custom Tests
WebPageTest	No strict limits	Yes, extensive configs	Scripting, headers injection, video capture
GTmetrix	Limited checks only	Yes, paid plans	Most features for paid users
Google PageSpeed	Fully featured	Actual field data	Not customizable
MachMetrics	Complete but no automation	Field metrics only	More features in paid tiers

Now let me elaborate my in-depth appraisal of each tool:

1. WebPageTest

I consider WebPageTest the most advanced suite a web performance technologist can utilize. Reasons are:

Test unlimited sites with long histories retained
Largest ecosystem of mobile devices in different geographies
Network simulation spanning modern 3G to upcoming 5G
Visual comparison between test runs
Waterfall charts with exact blocking calls
Easy custom scripting and edge case simulation

What does complex jargon above mean for you?

Compare mobile site speed in different network conditions
Benchmark speed on iPhones/Samsungs to understand real users
Check if your CDN or host affects delivery pace
Test special interfaces like AMP or mobile redirection

All this without any coding skills!

Of course, don‘t get intimidated by the myriad of knobs for non-techie users. The default setup itself provides great insight:

With unlimited free tests and long history retention of 90 days, WebPageTest earns my wholehearted recommendation.

2. GTmetrix

GTmetrix comes a close second with an excellent blend of ease-of-use plus reporting depth:

Test on 10+ preconfigured mobile devices or simply rely on lab emulated metrics – choice is yours.

I like how GTmetrix grades site performance and suggests specific areas for coding improvement. Further sections provide network request deep dives to isolate optimization areas.

The free plan only allows you to test individual URLs infrequently. I recommend getting unlimited checks via a paid subscription. Plans start around $15 per month with discounts for annual purchases.

3. Google PageSpeed Insights

When the creator of the Chrome browser itself makes PageSpeed Insights available for free, leverage it!

Google pioneered research into how extra seconds affect user experience and conversions. So metrics highlighted include:

First Contentful Paint under 1.8 seconds
Largest Contentful Paint below 4 seconds
Total Blocking Time within 300 ms

Granular technical feedback is tailored to developers. But I learned exact techniques to reduce JavaScript/CSS bloat through their guidelines.

Don‘t expect advanced customization in PageSpeed Insights. Take what Google gives for free – seriously!

4. MachMetrics

MachMetrics Speed Tool instantly evaluates user experience metrics promoted by Google Core Web Vitals research:

Quantities like Time to Interactive under 5 seconds affect whether visitors bounce early. MachMetrics makes such field data easy to understand even for non-technical folks.

The free test is enough for basic performance insight. Paid plans add monitoring, error tracking, and analytics capabilities too.

I utilize MachMetrics to educate clients on real-world mobile UX beyond just speeds. Recommended for quick yet compelling reporting.

5. DebugBear

DebugBear is fantastic for rapid testing with focus on user experience:

Metrics go beyond standard load times to highlight possible revenue gains through faster mobile page loads. Quantification of field data makes it easier to convince management!

For free users, DebugBear allows testing individual URLs infrequently. I recommend their $20 per month plan to unlock unlimited checks, custom connections, and performance monitoring.

6. DotCom Tools

I depend on Dotcom Tools for location-specific speed testing from over 30 regions globally:

Why geo-analysis? Many businesses host sites in single regions or use CDNs lacking strong worldwide coverage.

The consequence? Slow mobile page loads frustrating users in Asia, Europe or Africa!

Dotcom Tools helped me identify that a client‘s European mobile users suffered 10+ second delays compared to the US West Coast HQ where site hosted. Talk about dramatic shortcomings before customers revolted!

Their browser-based testing works excellently to uncover device and location-dependent mobile performance gaps for global sites.

7. Yellow Lab Tools

Yellow Lab Tools deserves mention for its custom scripting capability even in free tiers:

Why scripting? To simulate real-world scenarios like adding items to cart, search interactions etc instead of just landing page tests.

Developers can inject JavaScript to mimic user actions across a journey. Such hybrid synthetic monitoring uncovered sign-in struggles on a banking mobile app that basic load checks missed!

Definitely try out Yellow Lab Tools to evaluate complex user funnels beyond static page speed.

8. Additional Notable Tools

My article is long enough already! But a few more excellent options worth your radar:

SpeedCurve: For advanced web performance management combining monitoring, testing, analytics, and intelligence
Uptrends: Broad web performance toolkit including page speed, load testing, uptime checks etc
Pingdom: part of well-known monitoring toolkit with excellent speed test capability

Now over to sharpening your speed testing approach even further!

Step By Step Guide: How To Test Website Mobile Speed

While tools provide scores, how you interpret and take action matters more:

Step 1: Set Realistic Goals

Don‘t get dismayed by the highest standards shown for a Facebook or NYTimes. Set your own benchmarks aligned with analytics:

Example mobile performance targets:

Metric	Goal	Your Status
FCP (First Contentful Paint)	Under 1.8 s	2.3 s
LCP (Largest Contentful Paint)	Below 4 s	5.5 s
TTI (Time to Interactive)	Within 5 s	8.2 s

Step 2: Define Key User Journeys

Look beyond homepage tests to analyze signup funnels, campaigns etc:

Homepage -> Category -> Cart Addition -> Checkout
Login -> User Profile -> Subscription purchase
Contact Us -> Email form fill -> Submission

Step 3: Set Frequency

Schedule monthly checks across tools like:

WebPageTest: Automated daily run
GTmetrix: 2x monthly scans
PageSpeed Insights: Weekly reporting
Your own analytics vs targets

Step 4: Track Progress

Measure if targets met through:

Logging tool test history
Analytics improvement vs baselines
Customer satisfaction surveys

Share reports internally to accelerate fixes!

Remember to focus on worst performing user journeys instead of overall site averages. Sorting page types, geographies etc and comparing periodic scans makes it easier to quantify gains.
