«The vast majority of website problems we uncover in our audits are not mysteries. They are known, solvable technical errors – missing metadata, incorrect redirects, uncompressed images, unindexed pages. The frustrating part: each of these errors costs potential customers daily. The encouraging part: fixing them often takes hours, not weeks. In every audit we conduct, we find an average of 23 critical errors – and the first five fixes typically show measurable results within two to four weeks.» – David Bachetti, Founder & SEO Strategist

What is an SEO audit and why does your website need one?

An SEO audit is a systematic review of your website for anything that affects your visibility on Google and in AI search systems. It answers three questions:

 

What is technically blocking your website? Can Google even find, crawl, and index your pages? Do they load fast enough? Are they mobile-friendly?

 

Is your content correct? Do your contents target the right keywords? Is there duplicate content, thin pages, or missing meta-data? Can your contents be extracted by AI systems?

 

How do you compare? Which keywords are your competitors ranking for that you aren't covering yet? Where do you have authority gaps in your backlink profile?

 

The difference from a free website scanner: Automated tools provide technical metrics. A professional audit interprets this data in the context of your market, industry, and business goals – and translates it into a prioritized action plan.

The 8 most common SEO mistakes for Zurich websites

In over 200 website audits for companies in the Zurich area, we have documented the most common errors and which have the biggest impact on visibility. The results are clear: most websites fail not because of content, but because of technical fundamentals.

  1. Missing meta descriptions (78 %) – Instead of an engaging description, Google displays a random snippet of text. The click-through rate drops.
  2. No structured data / schema markup (73 %) – Google and AI systems cannot interpret the website correctly. Rich snippets and AI citations are not displayed.
  3. Images without alt text (67 %) – Google Images is being completely overlooked as a source of traffic. Accessibility suffers.
  4. Mobile load time over 3 seconds (59 %) – Google penalizes slow-loading pages. 53 % of users leave a page that takes longer than 3 seconds to load.
  5. Duplicate or missing title tags (52 %) – The most important ranking signal at the page level is incorrect. Google doesn't know what the page is supposed to rank for.
  6. No Google Business Profile or an incomplete one (44 %) – The quickest way to boost local visibility is being overlooked.
  7. Broken Links / 404 Errors (39 %) – Users and crawlers come up empty-handed. Link authority is lost.
  8. Missing H1 tags on core pages (35 %) – The most important heading on a page is missing or appears multiple times.

Frequently Asked Questions about SEO Audits

What does a professional SEO audit include?

A professional SEO audit checks your website on over 100 points in four areas: technical infrastructure (crawling ability, loading speed, mobile optimization), content quality (title tags, meta descriptions, keyword coverage), backlink profile (link quality, NAP consistency), and competitive positioning (keyword gap, content gap). You will receive a prioritized action plan showing which corrections will have the greatest impact.

Free online tools like PageSpeed Insights or Lighthouse measure technical metrics, but they don't interpret them. A professional audit places the data in the context of your market, your competitors, and your business goals. The result is not a score, but a prioritized action guide.

The full audit typically takes 5 to 10 business days, depending on the size and complexity of the website. The free initial check takes about 30 minutes. The presentation of the results takes place during a 60-minute meeting.

You decide. The audit report and the action plan are yours. You can implement the measures internally, have your team trained, or commission us with the implementation. There is no automatic follow-up contract and no pressure.

«Train your team»

 

For any company that wants to attract customers through its website. An audit is particularly useful before a website relaunch (to protect rankings), after a traffic drop (to find the cause), when switching SEO agencies (as a benchmark), or if the website is not generating inquiries despite investments.

Yes. In our Premium Audit, we systematically test what ChatGPT, Google Gemini, and Perplexity say about your company—and compare it with your competitors. From this, we derive concrete measures to improve your visibility in AI search systems.
