Website tracking tools help confirm availability, redirects, indexability clues, and crawler-facing behavior after pages are changed.
Every tool in this section is free and available to use right now — directly in your browser or through a live URL check. Some checks depend on browser support, public-URL access, or third-party data availability.

These four tools answer one practical question: what is actually happening with a URL the moment you hit enter? When a page disappears from search, traffic drops overnight, or a deploy goes out and you want to be sure it took effect, you don't need a 50-metric dashboard — you need to know whether the page is up, what status code it returns, where its redirects land, and what a crawler can actually read on it. Check Server Status reads live availability, DNS resolution, and HTTP headers; Is It Down runs the same address against several server-side probes so you can tell a real outage from your own flaky Wi-Fi; Redirect Checker traces every hop and its status code to the final destination; and Spider Simulator strips a page down to the text-oriented view a basic crawler extracts from the returned HTML.
A typical sequence chains three of them. Say organic clicks to a product page fell off a cliff. Start with Is It Down to confirm the page responds at all from outside your network — if it's a 500 or a timeout, that's your whole answer and the SEO theories can wait. If it responds fine, run Redirect Checker on the exact URL Google had indexed: a page quietly 302-ing to a staging host, looping, or chaining through three hops before a 404 is a classic cause of vanished rankings. If the redirects are clean and the status is 200, open Spider Simulator to see whether the content that matters is present in the raw HTML — if your copy and links only appear after JavaScript runs, a basic crawler may be seeing an almost-empty page even though your browser shows a full one.
What these checks tell you is bounded, and it's worth being honest about that. Every result is a snapshot of one request from one place at one time. Hosting, DNS propagation, and CDN edge rules can return different responses minutes apart or from different regions, so a single green check is evidence, not a guarantee of uptime. The crawler view is an approximation of how a simple bot parses HTML, not a reproduction of Googlebot's full rendering pipeline. And any index or coverage figure you see elsewhere on the site is a rough public estimate, never a search engine's internal database count. Treat all of it as directional.
The people who get the most out of this section are the ones doing diagnosis under time pressure: a developer verifying a redirect map after a site migration, an SEO confirming a noindex tag was really removed before requesting reindexing, a site owner checking whether the outage is real before escalating to their host. None of these tools require a login or a credit card, and they read only the public URL you give them — which is exactly what you want when you're trying to confirm a fact quickly rather than commit to a monitoring contract.

Use this section to connect research, diagnosis, and implementation rather than treating metrics in isolation.
Check Server Status returns the technical detail of a single request — availability, DNS resolution, HTTP headers, and the response code — so you can read exactly how the server answered. Is It Down focuses on the up/unstable/down verdict and runs the URL through several server-side probes, which helps confirm whether an outage is real or just a problem on your own connection. Use the first when you need the headers, the second when you just need a yes-or-no on reachability.
Redirect chains are one of the most common silent causes of lost rankings. A page that 302-redirects when it should 301, loops back on itself, hops through several URLs before resolving, or ends on a 404 will leak link equity or drop out of the index entirely. Redirect Checker traces every hop and its status code through to the final destination, so you can spot a broken or unexpected chain that a normal browser visit would hide from you.
Spider Simulator shows the text a basic crawler can extract from the raw HTML the server returns, before any JavaScript runs. If your content, headings, or links are injected client-side by a framework, your browser renders them but a simple bot may see a near-empty shell. That gap is a useful warning sign that important content might not be reliably crawlable, and it's worth checking whether your key text exists in the server response.
No. Every check here is a single request captured at one moment from one location. Hosting, DNS, and CDN edge rules can change a response between requests, and a problem might only appear from certain regions or under load. A passing check is good evidence the page works right now, but confirming sustained uptime needs repeated checks over time, not one green result.
Not directly. These tools check live behavior — availability, redirects, status codes, and the crawler-facing HTML — which are the conditions that have to be right before a page can be indexed well. For indexability signals specifically you'd pair them with a tool like the Indexability Checker, and any index-count figure should be read as a rough public estimate rather than a confirmed count from a search engine.
No signup and no paywall. Each tool runs against the public URL you enter, in your browser or through a live server-side check. They work on any publicly reachable address; pages behind a login, on a private network, or blocked to outside requests won't return meaningful results because the tools can only see what any anonymous visitor would see.
