Website check for businesses and agencies · in pilot
Know how findable your website is. Every day. Including in ChatGPT.
SEOpera checks your site for search visibility, AI visibility, speed and accessibility. Connect Google Search Console and Analytics to see which pages bring in visitors and where you are missing out.
SEOpera is only available in the Netherlands for now, in Dutch. Join the waitlist and you will hear from me when it opens in English.
Your website has more readers than you think
Google reads your site. So do ChatGPT and Perplexity, and the screen reader of a visually impaired visitor. A missing title, a slow page or a form without a label costs you visitors. Usually you only notice when revenue drops.
Most SEO tools only look at Google. SEOpera looks at all of these readers at once.
One score, four parts
Search visibility
Titles, meta descriptions, headings, links and structured data. Everything Google needs to understand your pages.
AI visibility
How well AI assistants such as ChatGPT and Perplexity can read and cite your site. If you are not in their answers, a growing group of searchers never finds you.
Speed
Core Web Vitals for your pages. A slow page costs visitors and rankings.
Accessibility
WCAG checks on contrast, alt text, forms and structure. Since 28 June 2025 the European Accessibility Act applies to many online shops.
SEOpera also checks your security headers.
How it works
Scan your site
Enter your web address. SEOpera walks through your pages and shows what it finds as it goes.
Connect Google
Link Search Console and Analytics with read-only access. You see which pages bring in traffic and which errors cost you that traffic. You can revoke access at any time.
Let it watch
Schedule a daily or weekly scan. When your score drops, you get an alert. Every week your score lands in your inbox.
What you get
A fix for every issue
Each issue says what is wrong, why it matters and how to fix it. Ready to forward to your web developer.
Reports you can share
Download your report as PDF or Excel. Or share it with a secure link.
Your progress at a glance
Every scan is kept. You see per part whether your site is getting better or worse.
No made-up numbers
If SEOpera cannot measure something, it says "not measured". That part then does not count towards your score. You never get an estimate dressed up as a measurement.
Who it is for
For business owners
You want to know whether your website is doing its job. Without becoming an SEO specialist. SEOpera tells you what is wrong and what to fix first.
For agencies
You build and manage sites for clients. With SEOpera you keep an eye on all of them and deliver a report your client understands.
From the maker
I am Vincent van Deth. I spent ten years in the financial sector, supervised by the Dutch regulators AFM and DNB. There I learned that a number is only worth something if you can trace where it came from. That rule is how I built SEOpera.
SEOpera is in its pilot phase. I work with a small number of companies and support them personally.
FAQ
What does SEOpera cost?
SEOpera is only sold in the Netherlands for now. Prices for other countries follow when it opens there.
Which Google data does SEOpera read?
From Search Console, per page: queries, impressions, clicks, click-through rate and positions. From Analytics, per landing page: sessions, users, new users, conversions, engagement, bounce rate and session duration. By default SEOpera counts organic traffic only, so it also reads the source and medium of each session. SEOpera only reads and changes nothing in your Google account. You can revoke access at any time.
Does it work for my website?
SEOpera scans any public website, whatever system it runs on. WordPress, Shopify, Webflow or custom built.
In which language are the reports?
The portal and reports are currently in Dutch. Join the waitlist if you need another language.
How is the total score calculated?
Search visibility weighs 35 percent, AI visibility 30, speed 20 and accessibility 15. If a part was not measured, the other parts share its weight in proportion.
Is SEOpera finished?
SEOpera runs as a pilot with a small number of companies. You get personal support and a direct say in what gets built.
