Without beating around the bush, website speed<\/strong> is today one of the most decisive factors \u2013 both for SEO<\/a> and for conversions. We have also written about this topic on LinkedIn<\/a>.<\/p>\n\n\n\n

That’s why it’s worth taking care of: investing in it, yes, but also testing it with a certain regularity. Because it can make the difference between a site in first position on Google and one relegated to the bottom of the page, or be an extra push to buy your products already in the cart.<\/p>\n\n\n\n

And no, you don’t need to become a developer to tell whether your site’s performance needs a second look: all it takes is five minutes and the right tool \u2013 a free one, at that.<\/p>\n\n\n\n

Here’s what we’ll cover in this article.<\/p>\n\n\n\n

Site speed is (almost) the only thing that matters<\/h2>\n\n\n\n

It’s a harsh, sad reality. You can have the most beautiful site in history, but if it takes more than five seconds to load, your visitor is long gone \u2013 probably to the competitor who thought about performance<\/em> too, and not just aesthetics.<\/p>\n\n\n\n

Google (for example) has known this for years, and in fact it has stopped treating speed as a technical detail reserved for developers and has instead made it a full-fledged ranking factor<\/strong>.<\/p>\n\n\n\n

But it’s a ‘problem’ that doesn’t only concern search engine rankings. A slow site loses users<\/strong> before they even get to read a single line of what you’ve written. And, as a consequence, it loses conversions before anyone has even seen your product or service.<\/p>\n\n\n\n

Site speed, in short, is one of those rare cases where working on the technical side improves rankings<\/strong>, user experience, and\u2026 revenue<\/strong> all at once.<\/p>\n\n\n\n

And it’s not just our impression; the numbers confirm it. The BBC<\/em>, for example, measured that it loses an additional 10% of its users for every extra second of page load time<\/a>. Google<\/em> and Deloitte<\/em>, in a joint study called Milliseconds Make Millions<\/a>, analyzed 30 million sessions across 37 international brands and found that an improvement of just a tenth of a second in loading time is enough to increase conversions by 8.4% in retail and 10.1% in travel.<\/p>\n\n\n\n

The good news in all this, though, is that speed is something you can optimize right away<\/strong>, and it delivers results right away \u2013 unlike a change of content strategy, which takes longer to produce a result, especially when it comes to SEO.<\/p>\n\n\n\n

For SEO, Core Web Vitals are central<\/h3>\n\n\n\n

Core Web Vitals<\/strong> are the metrics Google uses to measure the real experience of people browsing your site. When it comes to search engine rankings<\/em> (and therefore Google), this is also where you need to start.<\/p>\n\n\n\n

What do these “vitals”<\/em> indicate, that is, the “vital signs” for a site’s performance? Essentially three things: how fast it displays content<\/em>, how quickly it responds to interactions, and how visually stable it is while loading<\/em>.<\/p>\n\n\n\n

In practice, they measure three concrete aspects of the browsing experience<\/strong>. Three factors that effectively determine whether a user perceives your site as solid and reliable, or as something to close quickly.<\/p>\n\n\n

Now, let’s suppose your site isn’t performing as you’d hoped. Let’s also suppose, though, that you don’t yet have anything concrete in hand, just a simple impression of your own. What can you do?<\/em><\/p>\n\n\n\n

Here it is: there are plenty of possibilities. And above all, the web is full of free tools that can give you a more accurate picture<\/strong> of your site’s performance. With the data in hand, you can decide whether or not it’s worth choosing a web agency to optimize your site.<\/p>\n\n\n\n

The ones you’ll find below are the ones we use (and recommend) most often, each with a different strength depending on what you need to know. We’re talking about:<\/p>\n\n\n\n
