Security
I verify the encrypted connection (HTTPS) and five key security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options and Referrer-Policy) that protect your visitors from common attacks.
Enter a URL and I will check the basics of your website for free, covering security, performance and SEO, and suggest concrete improvements.

I measure how fast the site loads on mobile: when the main content appears, how much the layout shifts while loading and how long the browser is blocked (Core Web Vitals). A slow site drives away visitors and search engines alike.
I check whether the site tells search engines clearly what it is about: titles, descriptions, heading structure and indexability.
I review contrast, image descriptions and controls, so the site works for everyone and well on a phone.
From screenshots of the mobile and desktop view I assess clarity, readability and first impression. After the test I also look at the source code and send you a personal analysis by e-mail with concrete steps and the date of the test.
Yes. You get the basic result immediately and for free, without registration. I show the detailed analysis with recommendations once you leave your contact, also free of charge.
I store the tested address, the result and the IP address to protect the tool from abuse. I use your contact only to reply about your test and do not share it with anyone.
The basic result is usually ready within a few dozen seconds. The detailed analysis with recommendations takes a little longer.
Some websites block automatic checks or are temporarily unavailable. Try the test again later, or write to me and I will review the site by hand.
SEO (Search Engine Optimization) is a set of technical and content steps that help search engines like Google understand what your website is about and rank it higher in search results. This test checks the technical SEO basics: whether the site has correct titles, descriptions and a proper heading structure, and whether anything is blocking it from being indexed at all. The content and competitive side of SEO, such as text quality or backlinks, is not measured by this test.

I will go through the test results with you and suggest what to fix first. Non-binding and easy to follow.
