What is a SEO checker?

A SEO checker is a tool that scans a webpage and reports the SEO-relevant signals: title tag, meta description, canonical URL, headings hierarchy, structured data (JSON-LD), Open Graph + Twitter Card metadata, hreflang for multi-language sites, internal/external link graph, image alt-text coverage, and the technical signals search engines use to crawl and index the page. CitedRank's SEO checker returns a 10-section report on any URL — yours or a competitor's — in 12 seconds, with no signup required.

What is an on-page SEO audit?

An on-page SEO audit is a structured review of every SEO signal that lives on a single webpage — as opposed to off-page signals like backlinks. The audit checks meta tags, headings, schema, social cards, content structure, links, media, and technical implementation. On-page audits are the foundation of any SEO project because on-page fixes are typically the fastest, cheapest improvements you can ship.

How is CitedRank's SEO audit different from Ahrefs or Semrush?

Ahrefs and Semrush are full SEO suites — keyword research, backlink analysis, rank tracking, site audits — at $99-999/month. CitedRank's SEO audit focuses on one thing: a deep 10-section on-page audit for any single URL, free, with no signup. We don't track rankings or backlinks; we tell you everything that lives on the page. Use us for fast competitor analysis and pre-launch checks; use Ahrefs/Semrush for ongoing programs.

Does the SEO audit work on JavaScript-rendered pages?

Yes. We render every page with headless Chromium before extracting signals, so React, Vue, Next.js, and other SPA frameworks return accurate results. Static-HTML-only tools miss most modern sites' meta tags — we don't.

How fast is the SEO audit?

First fetch takes 10-15 seconds (Chromium rendering + signal extraction). Subsequent audits of the same URL return cached results in under 200 ms. The cache is shared with Crawl and Clone — running any of those tools on a URL also pre-populates the SEO cache.

What people say

Used by SEO consultants, content marketers, and dev teams shipping pages daily.

“The 10-section format is the killer feature. I used to run 3 tools to cover what this does in one paste — Open Graph debugger, hreflang checker, JSON-LD viewer. Now it's one URL and 12 seconds.”

Olivia Martinez

Freelance SEO consultant

“I audit every long-form post before publishing. The 'meta description length' check alone has saved me from shipping 60% of my posts with truncated SERP previews.”

Hiroshi Tanaka

Content lead · Fintech SaaS

“We bake the CitedRank audit into every prospecting deck. Free, no signup, polished output — the prospect sees we already did homework before we charged a cent.”

Aisha Khan

Agency partner

“I'm a dev, not an SEO. The audit tells me in plain English what tag is missing. Added the 3 fixes it suggested for my landing page — organic traffic up 40% in 6 weeks.”

Tom O'Connor

“The hreflang section is gold for multi-language sites. Lists every alternate locale + x-default in one view. Faster than Sistrix for the kind of audit I do daily.”
