Seven free audit tools and two browser extensions that catch missing tags, dead links, hidden scripts and bloated images, before they cost you rankings.
Most audit tools make you sign up before showing a single result. Ours doesn't. Paste a URL, wait a few seconds, and read a report written in plain English, not a wall of technical jargon only an engineer could love.
Drop in any web page, yours or a client's. Nothing to install.
Our crawler follows every internal link against 10+ audit rules.
A plain-English list of what's broken, ranked by priority.
Run each check separately or work through them like a pre-launch list.
Scan any page and surface missing meta tags, broken heading structure, and keyword gaps.
Run tool →Crawl your site and flag every 404 before your visitors, or Google, find them first.
Check now →Trace redirect chains across your pages and catch loops or unwanted hops.
Trace redirects →Scan your homepage for malware signatures, malicious scripts, and hidden iframes.
Scan for threats →Reveal elements set to display:none, the kind of cloaking that gets sites penalized.
Find elements →Generate a clean XML sitemap so crawlers index every page, not just some.
Generate sitemap →Some checks are easier to run right on the page you're looking at, instead of pasting a URL into a separate tab. That's what these two extensions are for, same audit logic, one click away, wherever you're browsing.
Color picker, font inspector, page ruler, tech detector, SEO analyzer, image compressor and screenshot & annotate.
Point it at any Shopify storefront and instantly see what's powering it, theme, apps and tech stack.
SiteAuditHub doesn't care what your site is built on. Point any tool at any URL, WordPress, Shopify, a static site, a React app, and get the same clean, honest report every time.
Every tool works from a plain URL. Nothing to configure, no key to generate, no rate-limit dashboard to babysit before your first scan.
Reports are structured so they're easy to scan visually or hand straight to a client, not raw JSON you have to format yourself.
The Chrome extensions run entirely in the browser. No server round-trip for things like color picking or font inspection.
Dozens of technical checks, boiled down to a score and a ranked list of fixes.
We built SiteAuditHub because most "free" audit tools aren't really free, they ask for an email, a login, or a card before showing a single result. Ours doesn't, and that's on purpose.
Most scans return a full report in under ten seconds. We don't queue your request behind a paywall or a waitlist, you paste a URL and the crawler starts immediately.
We don't create an account for you, we don't save your scan history, and we don't email you about it later. The URL is fetched, analyzed, and forgotten.
Every report explains what's wrong in plain English and tells you what to fix first, not a raw dump of technical flags only a developer could decode.
SEO, links, redirects, malware, hidden content and sitemaps, all seven tools share the same design and the same report format, so nothing feels bolted on.
