🔍 URL Total Check
An all-in-one tool that audits HTTP headers, security, SEO, structured data, LLMO, DNS, and SSL certificates with just a URL.
📖 What this check tells you
This combined check looks at one URL across eight areas at once: security, SEO, structured data, LLMO, DNS, SSL, cookies and caching. It does not replace the individual checks — it is the entry point for deciding where to start. Each area is only summarised here, so follow anything red into its dedicated page. Note also that it examines the single page you enter and does not crawl the rest of the site.
| Item | What it means | How to fix it |
|---|---|---|
| 🛡️ The security block is red | This looks at response headers such as HSTS, CSP and X-Content-Type-Options. Most of it is fixable with a single header line without touching application code, which makes it the best return on effort — put it first in your queue. | Details are in the security overview, the per-header breakdown in the HTTP header check, and the HSTS max-age and preload eligibility in the HSTS check. |
| 🔎 The SEO block is red | These are the elements that must appear exactly once per page: title, meta description, h1, canonical, hreflang. Inconsistencies like two h1 tags or a canonical pointing at another page will not be solved by adding more content. | The pass/fail per item and the recommended lengths are in the SEO basics check. A canonical that unintentionally points elsewhere is usually caused by a chain of redirects, so run the redirect chain check as well. |
| 🗂️ Structured data and 🤖 LLMO | This confirms that your JSON-LD is syntactically valid and that you are not blocking AI crawlers. Validity is as far as any checker can go. Whether the markup agrees with what the page actually shows is not machine-detectable — and it is exactly the part treated as a guidelines violation. | Required properties per type are listed in the structured data validator. If you mark up FAQ or HowTo, generate the visible HTML and the markup from the same data. Crawler permissions are in the LLMO check and robots.txt syntax in the robots.txt validator. |
| 🌐 DNS, 📜 SSL, 🍪 cookies, ⚡ caching | These four are site-wide, or even domain-wide, settings rather than per-page ones, so fixing them once fixes every page. The converse is that leaving them red while polishing individual pages keeps the symptom present across the entire site. | Record details are in the DNS record check, certificate expiry and the intermediate chain in the SSL check, and negotiated suites in the cipher suite check. Cookie attributes are in the cookie inspector and Cache-Control combinations in the cache header check. |
If the same URL yields different results, the site may be varying its response by cookie, User-Agent or region. Note too that this check does not execute JavaScript: on a SPA whose body text exists only on the client, the SEO block comes back nearly empty — which is close to what a crawler sees. Do not stop at the home page; measure one listing page and one article page too, because a different template gives a different result.
