How to Test Your Site Right Now — Free
The fastest way to know if you have a problem is to test it. Here are three free tools that will tell you exactly where your site stands — no tech skills required.
Tool 1: Google's Mobile-Friendly Test
URL: search.google.com/test/mobile-friendly
Paste your homepage URL in. Google scans the page and tells you if it passes the mobile-friendly test. If it doesn't, it will list the specific issues — small font sizes, content wider than the screen, clickable elements too close together, etc. Run it on your homepage, services page, and contact page at minimum.
Tool 2: PageSpeed Insights
URL: pagespeed.web.dev
This tells you how fast your site loads on mobile and gives you a score out of 100. It also lists specific opportunities to speed things up — typically things like 'compress images,' 'eliminate render-blocking resources,' or 'serve images in next-gen formats.'
A PageSpeed score below 50 on mobile is not a minor issue. At that speed, more than half your mobile visitors are leaving before your page fully loads. This directly costs you customers.
Tool 3: The 30-Second Phone Test
Open your website on your phone right now. Ideally, do this on a cellular connection (turn WiFi off) to simulate what most mobile visitors experience. Go through this checklist:
- Can you read the text without zooming?
- Does the page load in under 3 seconds?
- Can you tap the phone number to call immediately?
- Can you find and use the navigation menu?
- Do any images, buttons, or text get cut off?
- Can you scroll down without content jumping around?
- If there's a contact form, does it work easily on a phone keyboard?
Anything that feels frustrating to you — a potential customer who doesn't know you yet will give up on it.
Save your results. In Lesson 5, you'll paste them into a ChatGPT prompt that turns your issue list into a custom fix plan.
If you run PageSpeed and your mobile score is below 50, the single most impactful thing you can do is compress your images. TinyPNG.com is free, takes 60 seconds per image, and often doubles your mobile speed score.
