Swiss Plumbing Websites Compared

The plumbing industry is a cornerstone of Swiss craftsmanship. But how is their online presence? We analysed 1,626 Swiss plumbing businesses.

The most surprising result first

43% of plumbing companies have no website. Of the 1,626 businesses analysed, 696 have no web presence of their own. In an era where potential customers search online first for a tradesperson, this is a significant competitive disadvantage.

The good news

Of the 935 companies with a website, we successfully analysed 818. The average score is 76.3 out of 100 points. A solid result.

Score distribution overview

Over 94% of plumbing websites score at least 60 points. This shows that those who have a website have usually invested in a decent implementation.

Industry strengths

Plumbing websites perform particularly well in these areas:

Technical foundations are solid:

95.8% use a .ch domain
94% pass Core Web Vitals

Customer focus is present:

94.9% display contact information prominently
98.4% use ARIA attributes for accessibility
95.4% have properly labelled forms

SEO basics are in place: The average SEO score is 81.2 points. This is the highest value across all categories.

Where there is room for improvement

Our analysis also reveals clear areas for improvement:

Performance is the biggest issue

With an average of only 56.6 points, performance is the weakest category. The details:

Browser caching: Almost every website is missing out on faster load times here
Image optimisation: Only 35.7% compress their images properly
JavaScript optimisation: Only 45.2% load scripts efficiently

This is problematic: slow websites lose visitors. Google also penalises them in rankings.

Legal requirements and trust

Imprint/Privacy policy: Only 45.6% have complete legal pages. This is mandatory in Switzerland.
UID number: Only 54.1% display their business identification number. While not required by law, it builds trust with potential customers.

Accessibility has gaps

Colour contrast: Only 41.2% meet the minimum requirements
Image alt text: 16.7% of websites have images without alt text

For older customers or people with visual impairments, this can make the difference between being able to use the website or not.

Particularly problematic: upon closer inspection of websites that score poorly here, it often appears that the contact section is difficult to read due to the chosen colours.

Swiss hosting: an underestimated topic

Only 59.5% of websites are hosted in Switzerland. While this is not the most important factor for trade businesses, it is a trust factor for some customers. Local hosting can also slightly improve loading times.

Key takeaways

No website means lost customers. 43% of the industry is unfortunately not sufficiently positioned online.
The basics are usually right. Those who have a website do many things correctly: mobile optimisation and contact details are standard.
Performance is neglected. Image optimisation and caching are quick wins that almost no one uses.
Legal requirements are underestimated. Proper imprint and privacy policy are missing from over half of websites.

What can plumbing companies do?

Quick wins for immediate improvement:

Compress images (e.g. with TinyPNG or WebP format)
Enable browser caching
Add imprint and privacy policy
Display UID number on the website
Add alt text for all images

Long-term measures:

Switch to Swiss hosting
Write meta descriptions for all pages
Check and adjust colour contrasts

Conclusion

With an average score of 76.3 points, the Swiss plumbing industry performs well. At least the 57% who have a website at all.

The greatest potential lies with companies that have no online presence whatsoever. And for everyone else: with a few targeted optimisations, especially in performance and legal pages, the score can be significantly improved.
