Is My Page Speed Really A Problem?

What does your page speed score actually mean?

Your page speed score measures a simulation, not your real visitors. Lighthouse loads your site once, on a pretend phone, over a deliberately throttled connection, in a data centre somewhere. One test, one load, on hardware that is not yours.

That is what the number out of a hundred is. A lab result.

Google's ranking systems use something different, called field data. That is your real visitors, on their real phones, on their real connections, over the last twenty eight days. Thousands of actual people instead of one simulated one.

The two disagree constantly. I have watched red-scoring sites give every real visitor a fast experience. I have watched green-scoring sites leave real people waiting.

So the score is not useless. It is just not the thing you were told it was. It cannot tell you whether you are slow, and it definitely cannot tell you whether you are slow compared to your competitors.

How fast are the sites you are actually competing with?

The sites ranking in your niche and market pass Google's speed thresholds between 40% and 71% of the time, depending on the niche. Failing is normal. In most industries, roughly a third to a half of the sites ranking for your terms are failing right now.

We built the benchmark ourselves because nobody publishes this.

Across 38,950 domains ranking for commercial keywords in twelve industries and five markets, between 40% and 71% pass Google's Core Web Vitals thresholds, depending on the niche. SaaS performs worst at 40%. Professional services performs best at 71%. These are sites that already rank, not a general sample of the web.

That last line matters. This is not an average of the internet. It is a sample of sites that are already winning. That makes it the only comparison worth anything to you.

The spread surprised me. I would have bet on software companies being the fastest, because they build websites for a living. They are the slowest group we measured in all five markets, eleven points behind the next slowest.

Every number here carries a margin of error of 1.7 to 2.8 percentage points. One of our sixty cells failed our own reliability testing. Treat that one as indicative: travel in the UK.

And for one group, we could not measure anything at all, because Google holds no data.

What if Google has no speed data for your site?

You do not have enough traffic for speed to be your bottleneck, if Google holds no real user data for your site. That is the whole answer, and it is good news.

Chrome only reports on a site once enough real people visit it. Below that threshold, there is nothing to report. Not to you, not to your agency, not to Google's own ranking systems.

In local services and trades, 80% of the domains that rank have no field data at all. Four in five. Plumbers, electricians, dentists, all ranking, none measurable.

Here is what that tells you. If you are in that group, speed cannot be the reason you are invisible, because you do not have enough visitors for anyone to measure your speed in the first place. Something else is holding you back. You would be paying to speed up a site for visitors you do not have yet. That is the most expensive way I know to solve nothing.

None of that answers the question you came here with, which is whether any of it affects your SEO.

Does your page speed score affect your SEO?

Your page speed score does not affect your SEO. Core Web Vitals do. They are a real ranking signal, and they are measured from your real visitors rather than from the score.

You do not have to take my word for it. Google says it in their own documentation:

trying to get a perfect score just for SEO reasons may not be the best use of your time.

That is not a hot take from an SEO on the internet. That is the company that built the score telling you not to chase it.

Read that carefully, because the distinction is the whole game. The score is a lab simulation, and it is not a ranking factor. Core Web Vitals come from real people, and they are a ranking factor. Chasing the first one does nothing for the second.

The people telling you to fix it are usually the people selling the fix.

Why does every other page tell you to fix your speed?

Every page I checked ranking for this question is published by a company that sells a speed fix. Caching plugins, page optimisers, hosting companies, SEO tool suites.

I am not accusing anyone of lying. Their advice is usually technically correct. But every one of them has a commercial reason for you to believe speed is your problem, and not one of them benchmarks you against anything.

Think about why. A benchmark can come back and say you are fine. That is a terrible outcome if you sell page optimisation and a useful one if you are the business owner deciding where the budget goes.

We sell SEO education and SEO services. We do not sell speed. Which is exactly why we are happy to build a tool that tells most of you to walk away. And why the next section only matters if you are one of the few who genuinely failed.

If your speed is a real problem, what should you fix first?

If you are genuinely failing, start with your largest contentful paint, usually shortened to LCP. It measures how long your biggest visible element takes to appear, usually a hero image or a headline.

It is the metric that fails most, in every single industry we measured. LCP fails for between 20.3% and 48.0% of ranking sites. The other two fail far less often. Interaction delay fails for between 5.0% and 26.1%.

Two honest caveats. In ecommerce the three metrics are almost tied, so that advice is weaker there. And Google publishes this data in a way that slightly understates interaction problems, so treat the direction as solid and the exact gap as approximate.

LCP usually comes down to an oversized hero image or a slow server response. In my experience neither one is a rebuild.

Then stop. Check it once, fix it if it fails, and put the rest of the budget somewhere it compounds instead.
