Spending on ads but getting no customers? Your site may be quietly turning visitors away.
Before raising your ad budget, make sure your website isn't where customers slip away. Enter a URL to see what's holding it back.
In short
- The problem: You spend on ads, but visitors leave because the site is slow, hard to use on mobile, and weak on technical SEO.
- What I check: The whole site — speed, Core Web Vitals, technical SEO, and user experience.
- What you get: A clear report with a few things to fix first so the site loads faster and keeps more visitors.

Frequently Asked Questions
How is the free tool different from the deep manual audit?
The free tool on this page gives you a quick surface-level score. The deep manual audit is when I personally review your code structure, UX, and user funnel — providing a detailed Action Plan. That deeper review is something I share during direct conversation.
How is this different from PageSpeed?
PageSpeed gives technical metrics. This report combines Core Web Vitals + SEO + UX with real "Business Context" — identifying which errors cost you money.
Is my data safe?
The tool only reads public data, the same way Googlebot does. What you send through the form goes straight to my personal inbox over HTTPS — this is a static site with no database behind it, and I do not sell or pass your details to any third party for commercial purposes.
Can I use it for Japanese websites?
Absolutely. With 14 years of JP-market experience, the diagnostic is optimized for Hreflang and specific JP-VN SEO standards.
How long to receive the report?
After we align on the scope and requirements, I send the detailed report with an in-depth analysis within 24 business hours.
