Free Domain Health Checker for Startups
Check your SSL, sitemap, robots.txt, meta tags, page speed, and mobile friendliness in one instant scan — then see what to fix before building your customer acquisition plan.
A domain health checker scans your site's technical foundations — SSL, sitemap, robots.txt, metadata, speed, and crawlability — so you can fix what's blocking your search and AI visibility before investing in customer acquisition.
What the domain health checker reviews
The domain health checker runs an instant scan of the technical foundations that affect whether buyers — and search and AI engines — can find your site. In one check you see your SSL status, sitemap, robots.txt, meta tags, page speed, mobile friendliness, and crawlability, with plain-English notes on what's healthy and what's holding you back.
SEO readiness
Before content can rank, the basics have to be in place: a reachable sitemap, sensible robots.txt rules, unique title tags and meta descriptions, and pages that return clean 200 responses. The checker flags the common issues — missing or duplicate metadata, a blocked or absent sitemap, broken canonical setup — that quietly cap your search visibility no matter how good your content is.
AI visibility readiness
AI answer engines can only cite what they can crawl and parse. The checker looks at whether AI crawlers are allowed, whether your content is in the initial HTML (not hidden behind JavaScript), and whether structured data is present — the same signals that decide if ChatGPT, Claude, and Perplexity can understand your site. For a deeper, AI-specific scan, pair it with the AI citation checker.
Technical crawl basics
- Valid, active SSL certificate (HTTPS).
- An accessible XML sitemap at /sitemap.xml.
- A robots.txt that allows important pages and the right crawlers.
- Reasonable page load speed and a mobile-responsive layout.
Content and conversion signals
A technically perfect site still won't grow if visitors don't understand what you do or what to do next. The check surfaces basic content and conversion signals — clear titles, a focused value message, and a visible call to action — because traffic only matters if it converts into conversations and customers.
What to do after the check
Fix blockers in order of impact: first anything that stops crawling (blocked bots, missing sitemap, broken SSL), then metadata and structured data, then speed and mobile, then content clarity. Once the foundations are healthy, the higher-leverage work is acquisition, which is where finding buyers and publishing ranking content takes over from a one-time technical scan.
How Distro helps
A healthy domain is the starting line, not the finish. Distro takes it from there: Distro Copilot finds the buyers evaluating tools like yours on X, LinkedIn, and Reddit and drafts outreach in your voice for you to approve, while the Content Engine publishes long-form SEO articles that rank on a healthy technical base and work to get you cited in AI answers. The checker tells you what's blocking you; Distro does the work to actually get customers.
Frequently asked questions
What is a domain health checker?
It's a free tool that scans your website's technical foundations — SSL, sitemap, robots.txt, meta tags, page speed, mobile friendliness, and crawlability — and tells you in plain English what's healthy and what's blocking your search and AI visibility, with no signup required.
Is the domain health checker free?
Yes. Enter your URL and the checker runs an instant scan with results and recommendations, no signup or credit card needed.
What's the difference between this and the AI citation checker?
The domain health checker covers broad technical and SEO basics (SSL, sitemap, speed, mobile, metadata). The AI citation checker runs a deeper, AI-specific scan of 18 signals that determine whether ChatGPT, Claude, and Perplexity can cite you. They complement each other — start with domain health, then run the AI citation check.
What should I fix first after running the check?
Fix in order of impact: crawling blockers first (blocked bots, missing sitemap, broken SSL), then metadata and structured data, then speed and mobile, then content clarity. Crawling issues matter most because they can make everything else invisible.
Does a healthy domain mean I'll get customers?
No. It removes the technical blockers, but customers come from distribution: content, conversations, and outreach to the right buyers. A healthy domain makes that work pay off faster. Distro handles the acquisition side once your foundations are sound: it finds buyers, drafts outreach you approve, and publishes ranking content.
