Enter any domain and we'll check your DNS and email records — then explain in plain English what each result means and whether anything needs fixing. Unlike MxToolbox, we tell you what to actually do.

Check your SSL certificate and HTTP security headers. A missing security header won't break your site — but it will fail a security audit and can expose your visitors. We show you exactly which headers to add and how.

Generate ready-to-use schema markup code for any page type. Schema tells Google and AI systems exactly what your page is about — it's what gets you into AI Overviews and rich search results. Copy the code and paste it into RankMath.

Check whether your website's public-facing content contains patterns that could make it vulnerable to prompt injection — where malicious instructions embedded in your content could manipulate AI systems that read it. This matters if you have AI chatbots, AI-generated summaries, or want AI systems to cite you accurately.
