Website Performance Checklist for Irish Businesses

We see this play out regularly, so let me describe a typical case. A business owner gets in touch because online enquiries have dried up. The website looks fine on their office desktop. The content is up to date. They have been posting on social media, doing everything they were told to do. But something is off and they cannot figure out what.

On a call last week, I asked one of these owners to pull out their phone and load their own site. Not on the office Wi-Fi. On mobile data, the way their customers actually see it. The pause on the line told me everything before they said a word. Seven seconds. Eight. The spinning wheel just sat there.

They thought the problem was Google. Or the economy. Or that people just do not use websites anymore. It was none of those things. Their site was slow, their security certificate had lapsed, and their last backup was from eight months ago. They had no idea because nobody had told them what to check.

This checklist exists so that does not happen to you. Six checks, ten minutes, zero technical skills required.

1. Run a Page Speed Test

Go to Google's PageSpeed Insights ^[1], type in your website address, and hit Analyse. You will get two scores, one for mobile, one for desktop. Focus on the mobile score. That is the one Google uses for ranking, and it is the one your customers experience most often.

If your mobile score is above 80, you are in solid shape. Between 50 and 80, there are improvements worth making. Below 50, your site is actively working against you.

Here is the part most business owners miss. A slow site does not just annoy people. According to Google's own research, over half of mobile visitors abandon a site that takes more than three seconds to load ^[2]. That is not a minor inconvenience. That is potential customers walking away before they see what you offer, before they read your menu, before they find your phone number, before they know you exist.

The good news is that most speed problems are hosting problems, not content problems. The same website running on a properly optimised stack with Nginx, Redis caching, and server-level performance tuning will score dramatically higher than it does on budget shared hosting. If your score is poor, the first question to ask is not "what did I do wrong?" but "is my hosting actually delivering?"

We wrote a complete WordPress performance guide that breaks down what makes the difference if you want the technical detail.

2. Open Your Site on a Phone

This one sounds obvious. It is not.

Most business owners check their website on a desktop or laptop in their office, connected to broadband. That is not how the majority of their customers see it. Step outside. Open your site on your phone using mobile data. Watch the page load. Tap every button. Fill in the contact form. Try to find your phone number.

If anything frustrates you, it is frustrating your customers far more, because they have less patience and more alternatives.

The Deloitte "Milliseconds Make Millions" report, commissioned by Google and notably published through Deloitte Ireland, found that a 0.1-second improvement in mobile site speed correlated with retail conversions increasing by somewhere in the region of 8% to 9% ^[3]. A fraction of a second. Translating directly into revenue. Now imagine what a five-second delay is doing.

Your customers experience your website on their phones, not your office desktop.

Consider a typical case we see often: a gift shop on the Galway Quays with beautiful product photography, but every image loading at full resolution on mobile. Several megabytes per page over a 4G connection. Compressing those images properly cut the load time in half. That is the kind of fix you only discover by actually using your own site the way your customers do.

3. Check Your Core Web Vitals Score

Core Web Vitals are Google's way of measuring whether your website provides a good experience. There are three metrics, and you do not need to understand the engineering behind them, just the thresholds ^[4].

Metric	What it measures	Good	Poor
LCP (Largest Contentful Paint)	How quickly main content appears	Under 2.5 seconds	Over 4 seconds
INP (Interaction to Next Paint)	How fast the site responds to taps and clicks	Under 200 milliseconds	Over 500 milliseconds
CLS (Cumulative Layout Shift)	Whether content jumps around during loading	Under 0.1	Over 0.25

You can see all three in the same PageSpeed Insights report you ran in step one. If any of them show red, they need attention. If all three are green, your site is outperforming the majority of websites on the internet.

Why does this matter beyond the numbers? Because Google uses Core Web Vitals as a ranking signal. Not the dominant one, and not the only one, but a tiebreaker between otherwise similar pages. If your competitor's site passes and yours does not, they get the edge in local search results. For a business that relies on being found on Google, that edge translates directly into enquiries and revenue.

4. Verify Your SSL Certificate Is Active

Open your website in a browser. Look at the address bar. Do you see a padlock icon? If yes, your SSL certificate is working. If you see "Not Secure" instead, you have a problem that needs fixing today.

Google confirmed HTTPS as a ranking signal back in 2014 ^[5]. But in 2026, the real issue is not the minor SEO benefit. It is trust. A "Not Secure" warning tells your customers that your website is not safe to use. For any business that takes enquiries, bookings, or payments through their site, that warning is the digital equivalent of a closed sign on your door.

SSL certificates should be free. Let's Encrypt provides them at no cost, and any decent hosting provider includes them and handles renewal automatically. If your current host charges extra for SSL, that alone tells you something about the value you are getting.

I made a mistake with this one early in my career, actually. Recommended a hosting provider to a client without checking whether SSL was included. It was not. They ran for three months with a "Not Secure" warning before anyone noticed. Contact form submissions had dropped to almost nothing. The certificate cost nothing to add. The lost leads cost plenty.

5. Know Whether Your Site Was Up Last Month

Here is a question most business owners cannot answer: was your website available 24 hours a day, 7 days a week, last month? Not "I think so." Not "it seemed fine." Do you actually know?

If your hosting provider does not show you uptime data, you are flying blind. Your site could go down for two hours on a Tuesday afternoon while a potential customer is trying to book an appointment, and you would never know. They would just leave and try someone else. No error message lands in your inbox. No missed call appears on your phone. The customer simply disappears.

Free tools like UptimeRobot will check your site every five minutes and alert you when it goes down. Set one up. It takes two minutes. Then at least when something breaks, you find out before your customers tell you.

The alternative is discovering it from a frustrated customer on social media. Or worse, never discovering it at all and wondering why enquiries dropped that week.

6. Confirm Your Backups Are Running

This is the checklist item most people skip. It is also the one that matters most when everything goes wrong.

Log into your hosting dashboard. Find the backups section. Check when the last backup ran. If you cannot find it, if the last backup was months ago, or if there is no backup feature at all, that is a serious risk sitting underneath your entire online presence.

A hacked site with no backup means rebuilding from scratch. Not restoring. Rebuilding. Every page, every product listing, every customer testimonial, every image you uploaded, every contact form you configured. Gone. According to the Disaster Recovery Journal's 2024 survey, roughly a third of businesses that faced data disruption could not recover their lost data ^[6]. Not because recovery was impossible, but because nobody had set up the backups in the first place.

One honest caveat here: a nightly backup is only as good as its last run. If you make fifty changes during the day and something breaks at 11pm, those changes are gone. That is the tradeoff with any nightly backup system. The alternative, no backup at all, means losing everything instead of one day's work. Know the difference.

With Web60's enterprise-grade Irish hosting infrastructure, automatic nightly backups run without you lifting a finger. One-click restore if you need it. Pre-update safety snapshots taken automatically before any changes. The worst case scenario is rolling back a single day, not starting from zero.

When You Need More Than a Checklist

This list covers the fundamentals, and for most business websites it covers what matters. Brochure sites, service pages, small online shops: these six checks will catch the issues that cost you customers.

But if you are running a complex eCommerce operation with thousands of products, custom payment integrations, and heavy seasonal traffic spikes, you may need a professional performance audit. Dedicated performance consultants and enterprise-tier managed hosts exist for exactly that workload, and for genuinely complex sites with dedicated development teams, they earn their fees. That is not most businesses, though. For the majority of local firms and independent retailers, the hosting infrastructure doing the heavy lifting matters more than any consultant's report.

Conclusion

None of the items on this checklist require technical expertise. A phone, a browser, and ten minutes. That is all it takes to understand whether your website is working for your business or quietly working against it.

The pattern we see, over and over, is business owners who assume their website is fine because it looks fine on their office screen. By the time they discover the real picture, they have already lost months of potential customers to slow pages, broken mobile experiences, and expired certificates that nobody flagged.

Run the checklist. If everything passes, you have one less thing to worry about. If something fails, at least now you know exactly where to look.

Frequently Asked Questions

How do I check my website speed for free?

Go to Google's PageSpeed Insights (pagespeed.web.dev), enter your website URL, and click Analyse. You will get a score out of 100 for both mobile and desktop, along with specific recommendations for improvement. Focus on the mobile score, as that is what Google uses for ranking and what most of your customers experience.

What are Core Web Vitals and do they affect my Google ranking?

Core Web Vitals are three metrics Google uses to measure your website's user experience: loading speed (LCP), interactivity (INP), and visual stability (CLS). Google confirmed they are used as a ranking signal, though they function more as a tiebreaker between otherwise similar pages than as a dominant ranking factor. You can check yours for free in a PageSpeed Insights report.

How often should I run a website performance check?

Run the full checklist at least once a quarter. If you make significant changes to your site, such as adding new plugins, changing your theme, or uploading large images, run it again afterwards. Set up free uptime monitoring with a tool like UptimeRobot to get continuous alerts between manual checks.

Does my website need an SSL certificate in 2026?

Yes. Without SSL, browsers display a "Not Secure" warning that drives visitors away before they even read your content. Google also uses HTTPS as a ranking signal. SSL certificates from Let's Encrypt are free, and any good hosting provider includes them automatically. If your host charges extra for SSL, that is a warning sign worth paying attention to.

What is a good page load time for a business website?

Under three seconds on mobile is the target you should aim for. Google's own research shows that over half of mobile visitors abandon a site that takes longer than three seconds to load. Under two seconds is excellent. If your site consistently takes more than five seconds, it is losing you customers every single day.
