SEOLaunched Sep 2026

The story

Scan your entire website for crawlability, HTTP errors, internal link architecture, metadata gaps, server response speed, HTTPS, robots.txt, and sitemap health. The tool fetches robots.txt, discovers nested sitemaps, and checks each page up to 500 URLs. It combines technical SEO diagnostics with content-quality, internal-architecture, and AEO/DEO signals, then presents a composite score, subsection scores, page-level evidence, and an AI remediation prompt. No account or sign-up required. Free tier: 2 scans per IP per day.

Overview

nqzai Website SEO Health Check by Jev is a free diagnostic tool that audits websites across ten health dimensions: HTTP status, crawlability, internal links, content metadata, content quality, AEO and decision engine signals, sitemap accuracy, server performance, mobile signals, and HTTPS. The tool is designed for site owners, SEO professionals, and developers who need to identify and prioritize technical and content issues across multiple pages without manual review. It works by fetching robots.txt, discovering nested sitemaps, and crawling up to 500 URLs to surface observable problems with actionable evidence. The audit returns a composite score with subsection breakdowns, page-level findings organized by signal type, real-time token telemetry, and an evidence-bound AI remediation prompt that can be shared with developers or SEO agents. Unlike ranking prediction tools, this is a diagnostic crawl focused on revealing structural, technical, and content-quality gaps that affect discoverability and search engine access. The free tier allows 2 scans per IP per day with no account creation required.

Key features

FAQ

How many pages can the tool scan?

The tool scans up to 500 pages per audit. It discovers all URLs in your sitemap files and fetches them up to the 500-page cap.

Do I need to create an account?

No. The free tier requires no sign-up, account creation, or credit card. You can run 2 scans per IP per day.

What is the difference between this and a ranking prediction tool?

This is a diagnostic crawl that reveals observable problems in crawlability, metadata, links, and content quality. It does not predict Google rankings, traffic, or conversions.

Does it measure Core Web Vitals and mobile performance?

No. The tool checks for a viewport meta tag but does not render pages in a mobile browser or measure LCP, INP, or CLS. Use PageSpeed Insights or Lighthouse for complete performance reviews.

What are AEO and DEO signals?

AEO (Answer Engine Optimization) and DEO (Decision Engine Optimization) focus on how generative AI and autonomous agents extract and compare information. The audit checks Schema.org markup, data tables, social cards, pricing signals, and trust policies.
