How many times have you looked at your website and had the feeling that something wasn’t quite right, but couldn’t quite put your finger on it? The Italian SMEs lose up to 25% of turnover due to poor or incorrect data on the website, yet this problem is systematically ignored.

Criteria for identifying the most damaging errors
Before discussing specific errors, it is useful to understand how to measure them. Not all website issues have the same impact on conversions and online reputation. A broken link on a subpage is far less critical than a contact form on the homepage that isn’t working.
To assess the severity of an error, consider these four main criteria:
- Usability: To what extent does that error make navigation difficult for the average user? If a visitor cannot find what they are looking for within a few seconds, they will leave the site.
- Technical reliability: Does the error cause malfunctions, 404 errors, slow-loading pages or security issues? Serious technical errors affect both users and search engine rankings.
- Quality of information: Is the content up to date, accurate and consistent with what you actually offer? Incorrect or out-of-date information immediately undermines a potential customer’s trust.
- Mobile optimisation and SEO: Does the website work well on smartphones? Is it search engine-friendly? These two factors are now inseparable when it comes to attracting targeted traffic.
“Having a website isn’t enough: it’s like opening a shop with no shop window, no sign and a door that’s hard to open.”
A figure that clearly illustrates the situation: according to the Digital Intensity Index, 88% of Italian SMEs have at least a basic digital presence, but only 14% manage to generate actual online sales. This huge gap is not down to luck: it is down to specific mistakes that prevent conversions. Understanding the benefits of corporate websites It is only the first step; the second is to remove the obstacles that undermine them.
Pro tip: Before analysing your website, create a simple matrix with two axes: impact on conversions (high/low) and ease of correction (easy/difficult). High-impact, easy-to-fix errors come first. High-impact, difficult-to-fix errors are scheduled. The others are assessed later.
The 13 most common mistakes: the essential list
Now that the criteria have been set out, here is a list of the most common mistakes, which have been shown to have the greatest impact on turnover. For each point, you will find a practical description and the specific consequences.
-
Confusing navigation structure. Unclear menus, duplicate items or confusing hierarchies force visitors to struggle to find what they are looking for. A effective web design It should feature a menu with a maximum of 5–7 main items, intuitive labels and a logical path to the conversion pages. If your main menu contains 12 items and some of them are generic, such as “miscellaneous” or “other”, it’s time to review the structure.
-
Out-of-date content and incorrect information. Incorrect opening hours, a service you no longer offer, a telephone number that changed three years ago. These mistakes may seem minor, but they destroy trust instantly. Italian SMEs lose up to 25% of their turnover precisely because of this sort of problem with company data.
-
Lack of mobile optimisation. More than 60% of Google searches in Italy are carried out on smartphones. If your website isn’t responsive – that is, if it doesn’t automatically adapt to smaller screens – you’re missing out on the majority of your potential visitors. Text that’s too small, buttons that are too close together, and images that spill over the edges: these are immediate signs of a website that isn’t optimised.
-
Slow loading times. Every extra second of waiting time reduces conversions by around 7%. A website that takes more than 3 seconds to load is abandoned by the majority of users before they even see the content. The TTFB (Time To First Byte, i.e. the time between the browser’s request and the first byte received from the server) should be under 200 milliseconds. Large images, poor hosting and unnecessary plugins are the most common causes.
-
Complicated or non-functional contact forms. A form with 15 compulsory fields puts anyone off. A form that doesn’t actually send emails is a silent disaster: you lose valuable contacts without even realising it. Test your forms regularly and keep them to the bare essentials: name, email address and a message are often enough.
-
Poor visibility on search engines. Without a basic SEO strategy, your website is only visible to those who already know you. It lacks optimised title tags, meta descriptions, correctly structured H1 and H2 headings, and content relevant to your audience’s searches. The features of a corporate website Professional websites always incorporate a solid SEO foundation right from the development stage.
-
Unstructured or incomplete data. VAT number, address, opening hours, prices, product or service categories: when this information is missing or incomplete, search engines are unable to index your business correctly and Google My Business does not work to its full potential. Structured data (Schema Markup) helps Google understand who you are and what you offer, improving your visibility in local searches.
-
Unprofessional design. A website built using a 2012 template, with clashing colours, illegible fonts or a disorganised layout, immediately gives the impression of a lack of care and professionalism. Design isn’t just about aesthetics: it’s about trust. Find out how designing an effective homepage to make a first impression that converts.
-
Lack of clear calls to action. Every page on your website should guide visitors towards a specific action: requesting a quote, downloading a resource, buying a product or signing up for the newsletter. If a visitor arrives, reads the page and then doesn’t know what to do, they’ll leave without converting. An effective call-to-action is visible, specific and creates a sense of urgency or perceived value.
-
Neglected security: no HTTPS and out-of-date plugins. A website without an SSL certificate (the famous green padlock in the browser) is flagged as “not secure” by Chrome and Firefox, which immediately puts visitors off. Out-of-date WordPress plugins are the main entry point for cyber-attacks. Security is not optional: it is a basic requirement. The website design It must take safety into account right from the start.
-
Spelling and grammatical errors. They may seem trivial, but a text full of typos conveys a lack of care and incompetence. Google penalises low-quality content, and users lose trust in the brand. Before publishing any content, read it aloud and have someone else proofread it.
-
Large, unoptimised images. A photo taken on a smartphone and uploaded directly in its original format can be 5–8 MB in size. Multiply that by 20 images on the same page, and you end up with a website that takes 15 seconds to load. Use modern formats such as WebP, compress images to under 200 KB and always add the ALT attribute to improve accessibility and SEO.
-
No reviews or testimonials. Social proof is one of the most powerful conversion tools. If your website doesn’t feature genuine reviews from satisfied customers, case studies or logos of companies you’ve worked with, you’re missing out on a key advantage. 87% of consumers read online reviews before making a purchase or contacting a company.
Pro tip: Create a printable checklist with these 13 points and assign a person responsible and a deadline to each one. A monthly visual audit – even if it only takes 30 minutes – can prevent errors from piling up, which can then become costly to rectify.
Comparison and impact: just how significant are these errors?
Seeing the data in plain text helps you understand which errors you should prioritise your time and resources on straight away. Not all errors carry the same financial and reputational impact.
| Error | Impact on conversions | Impact on confidence | Estimated cost, unless otherwise stated |
|---|---|---|---|
| Incorrect/out-of-date content | High (up to -25% turnover) | Very tall | Direct loss of customers |
| No mobile optimisation | High (-50% mobile traffic) | High | Loss of organic traffic |
| Slow loading times | High (-7% conversions/sec) | Medium | Immediate abandonment |
| No call to action | High | Medium | Failure to convert |
| No HTTPS | Mid-to-high | Very tall | Google penalty |
| Unprofessional design | Medium | High | Loss of credibility |
| Form not working | High | High | Leads lost without a trace |
| No basic SEO | High (long-term) | Bass | Organic invisibility |
| Non-optimised images | Medium (speed) | Bass | Slow loading |
| No evidence | Medium | Mid-to-high | Lower confidence rating |
| Confusing navigation | Mid-to-high | Medium | Increase in bounce rate |
| Spelling mistakes | Low-Medium | High | Reputational damage |
| Structured data missing | Bass (short) | Bass | Less local visibility |
As the data in the table shows, errors relating to incorrect or poor-quality content pose the greatest financial risk: Italian SMEs can lose up to 25% of their turnover for this reason. This is not a minor issue.
The second priority is serious technical issues such as the absence of HTTPS, slow loading times and a lack of mobile optimisation. These problems adversely affect both search engine rankings and the user experience, creating a negative knock-on effect.
Content-related errors such as missing testimonials, spelling mistakes and outdated design have a more subtle but constant impact. They erode trust over time and drive undecided users towards the competition. Following best practices for effective web design helps to avoid these problems at a structural level, rather than simply correcting them after they have arisen.

When mistakes become opportunities for improvement
Now that the priority of these errors is clear, we need a practical strategy to correct them and turn them into opportunities. If tackled systematically, these errors can become the starting point for a more effective website and a more visible business.
Here’s how to draw up a practical action plan:
- Regular check-ups every 6 months. Plan a comprehensive website audit at least twice a year. Check every page, every link, every form and every piece of content. The time you invest in this will save you from unpleasant surprises: a changed telephone number that is only discovered after eight months of missed calls represents a real cost. Remember that around 30% of business data becomes outdated every year, rendering the information obsolete without you even realising it.
- Proofreading of texts and content, with particular attention to company data. Whenever something changes in your business, update your website within 24–48 hours. New opening hours, new services, price changes, changes of premises: this information must be accurate and consistent across all digital channels, not just on your website.
- Regular backups and security updates. Set up automatic daily or weekly backups. Update WordPress, plugins and themes at least once a month. A website compromised by a cyberattack can cost thousands of euros in data recovery and reputational damage.
- Use user feedback as a strategic resource. Install tools such as Hotjar or Microsoft Clarity to see how users navigate your website: where they pause, where they click, and where they leave. This data reveals hidden errors that no manual audit can detect. A simple post-purchase survey can reveal unexpected friction points in the contact or purchasing process.
- Use checklists and online support tools. Tools such as Screaming Frog for technical analysis, Ahrefs or SEMrush for SEO, GTmetrix for speed and Google’s Lighthouse for accessibility give you a clear and up-to-date picture of your website’s health.
Pro tip: Don’t wait for problems to crop up on their own. Create an editorial calendar for your website: plan for at least one content update, one technical check and one review of your analytics each month. It’s a habit that takes less than two hours a month but makes a huge difference over time.
The interesting thing is that correcting a mistake often opens up opportunities you hadn’t considered. A simplified contact form doesn’t just reduce abandonment: it can become the starting point for a structured conversion funnel. A mobile-optimised website doesn’t just stop losing visitors: it can become the main tool for acquiring local customers through “near me” searches.
The most underestimated mistake? A lack of a mindset focused on improvement
Having worked on hundreds of websites for Italian SMEs, I have learnt one thing that no list of technical errors can fully capture: the real obstacle to digital growth is almost never a single technical issue. It is the lack of a continuous approach to improvement.
Most small business owners only take action on their website at two specific times: when they set it up and when something visibly stops working. This reactive approach is precisely what allows errors to accumulate silently for months or years, eroding traffic, trust and turnover without anyone noticing until the damage has already been done.
SMEs that achieve real results online share one common trait: they treat their website as a living asset, not as a static digital brochure. They monitor analytics every week. They gather feedback from customers. They test different versions of their calls to action. They update their content regularly. They analyse why some visitors convert and others do not.
This does not require enormous resources. It requires a systematic approach and an awareness that the digital market changes rapidly. A competitor who updates their SEO strategy today could knock you off the top spots on Google within a few months. A website that fails to adapt to users’ changing expectations quietly becomes obsolete.
There is also an important psychological aspect. Many entrepreneurs and freelancers have a natural reluctance to “tinker” with their website for fear of breaking something. This fear is understandable but paralysing. The solution is not to avoid making improvements: it is to have a professional by your side whom you can trust. Choosing the right web professional It doesn’t mean losing control of your website: it means gaining the peace of mind that comes from knowing that someone is constantly monitoring, updating and improving what is, for you, a critical business tool.
The question I always ask myself when analysing a website is: does this website reflect the company you are today? Not the company you were three years ago, not the one you’d like to be in the future, but the real one as it stands today. If the answer is no, you’ve already identified the most important issue to address.
