It’s a never-ending challenge trying to get your website to load as fast as possible – ideally in under two seconds. That’s what Google expects now with its ‘mobile first’ approach, and it’s not so much a suggestion as a demand.
And to be fair, it makes sense. Look at your analytics – most visitors are on their phones, not laptops or desktops anymore.
Not all trends are worth the effort
Google’s mobile speed test loves to hand out advice like this:
- Ensure text remains visible during webfont load. Use the
font-displayCSS feature so text shows up while fonts are loading. - Defer unused CSS. Unnecessary style sheets slow down how quickly anything appears. Clean them out.
- Serve images in next-gen formats. Encode your images in JPEG 2000, JPEG XR, or WebP for smaller files and faster loading. Provide a fallback JPEG or PNG.
- Eliminate render-blocking resources. Inline critical JS/CSS and defer anything that isn’t vital.
Sounds reasonable enough… until you actually try it.
Is sub-2-second load time realistic?
Technically, yes. But in reality, only if you’re selective about which suggestions you follow. Some are just not worth the hassle. Take image formats, for instance.
Google talks about JPEG 2000 as though everyone’s using it. They’re not. Even Photoshop doesn’t let you export to JPEG 2000 by default – which tells you everything about how that “next big thing” turned out.
The myth of next-gen image formats
Google’s tools suggest WebP, JPEG 2000, and JPEG XR. Then they kindly include links to see if browsers actually support them. Spoiler: most don’t.
So, for now, stick with well-compressed JPEGs and PNGs. They work everywhere, and you’ll avoid hours of pointless tinkering.
UPDATE: Use WebP!
What on earth is a render-blocking resource anyway?
A render-blocking resource is something your page can’t load without. If a CSS file controls your page’s text styling, the text won’t appear until that CSS has loaded. If that takes an extra second, your whole page is delayed.
Now here’s the funny bit – and the reason this is a catch-22. Google itself is often the render-blocking resource!
Millions of websites use Google Fonts, which have to load from Google’s servers before your page appears. Then there’s Google Analytics, with its own JavaScript files that also need to load.
Yet Google tells us we must hit two seconds or less to get those search ranking brownie points.
See the irony?
Common Questions About Website Load Speed and Google’s Demands
Why Does Google Care So Much About Site Speed?
Because faster sites keep users happy. Google rewards pages that load quickly since speed improves experience and keeps people on the site longer.
What Does ‘Mobile First’ Actually Mean?
It means Google ranks your site based on mobile performance. If your mobile version is slow or clunky, your search position can drop even if desktop looks fine.
Is It Really Possible to Get a Website to Load in Under Two Seconds?
Yes, with effort. Fast hosting, compressed images, clean code, and proper caching can get most sites loading in under two seconds.
Should I Convert All My Images to WebP or JPEG 2000?
No, not yet. Browser support is still uneven, so stick with well-compressed JPEGs and PNGs until newer formats are universally supported.
What Are Render-Blocking Resources and Why Are They a Problem?
They’re files like CSS or JavaScript that must load before your page can display. If they take too long, visitors stare at a blank screen.
Is Google Really to Blame for Slowing Websites Down?
Partly, yes. Google Fonts, Analytics, and other scripts add extra requests that slow pages — ironic given Google’s own speed advice.
How Can I Balance Performance with Design?
Keep it simple. Use clean layouts, light graphics, and minimal scripts – a site that loads fast and works smoothly always beats one that looks flashy but drags.
