Check uptime, SSL score, DNS, MX records, blacklist, domain age, and server info.
In the digital world, website performance and security are the pillars of success. Whether you are a developer debugging a connection issue or a business owner ensuring your site is online, you need accurate data fast. Our **Free Website Diagnostic Tool** is an all-in-one solution designed to analyze the technical health of any domain. It pairs perfectly with our SEO Analyzer for a complete audit. From checking **Server Uptime (HTTP Status)** to verifying **SSL Certificate validity** and digging into **DNS Records**, this tool gives you a 360-degree view.
Technical issues often hide behind the scenes. A website might look fine to you but could be failing for customers or search engines. Our **advanced diagnostic scanner** helps you:
This tool acts as a **comprehensive technical audit**. For content-related checks, consider using our Word Counter or optimizing images with our Image Compressor.
Beyond just connectivity, our tool dives deep into the reputation of your domain. Knowing the **Domain Age** is critical for SEO, as older domains often carry more authority. If you are building a new site, ensure you setup redirects properly using our .htaccess Generator.
Additionally, we perform a real-time **IP Blacklist Check** against major anti-spam databases like Spamhaus. If your server IP is listed, your emails might be going to spam. Use this tool alongside our JSON-CSV Converter to export and analyze your technical data offline.
A: To **check if a website is down for everyone**, use our free diagnostic tool. Enter the URL, and our server will attempt to connect to the site. If it returns an **HTTP 200 OK** status, the site is online. If it returns a timeout or 500 error, the server is likely down. You can verify specific status codes with our Header Checker.
A: Yes, **Domain Age is a significant SEO factor**. Older domains are more likely to be trusted by search engines like Google than new ones. Use our tool to find the exact creation date. To further boost your authority, ensure you have valid schema markup using our Schema Generator.
A: If our tool shows your SSL is expiring, renew it immediately through your hosting provider (like Let's Encrypt). An expired SSL triggers security warnings, increasing bounce rates. Always ensure your redirects are set to force HTTPS using our .htaccess Generator.
A: Being listed on a blacklist like **Spamhaus** usually means your IP was flagged for spam. If you are on shared hosting, this might be due to another user. It generally affects email deliverability but not necessarily website ranking. Contact your hosting provider to resolve this.
