QuickSEO — SEO Checker & AI Visibility Audit Tool

QuickSEO is an on-page SEO checker and AI visibility audit tool that scans any web page and explains every issue in plain English with step-by-step fix instructions. Run a full SEO and GEO audit in one click — no signup, no server calls, everything runs instantly in your browser.

Unlike complex SEO analysis tools built for professionals, QuickSEO is designed for bloggers, small business owners, freelancers, and web developers who want to improve their website rankings in both traditional search and AI search engines. This on-page SEO audit tool speaks your language and shows you exactly what to fix for Google, ChatGPT, Perplexity, and Google AI Overviews.

HOW IT WORKS

Open the Chrome side panel on any web page and run a one-click site audit. The SEO checker scans the page, evaluates 30+ on-page SEO and AI visibility factors, calculates an overall SEO score from 0 to 100, and presents results in a clear report. Every check includes a plain-English explanation of what went wrong, why it matters for search engine optimization and AI search visibility, and a step-by-step guide on how to fix it.

ON-PAGE SEO CHECKS (30+ FACTORS)

Page Basics:
- Title tag analysis: length check (30-60 characters), keyword placement, duplicate detection

- Canonical URL verification to prevent duplicate content issues
- Robots meta tag & indexability status check

Content & Structure:
- H1 heading validation: presence, count (exactly one per page), keyword relevance
- Heading hierarchy analysis (H1-H6): proper nesting order, skipped levels detection
- Word count & content depth evaluation for thin content detection
- Text-to-HTML ratio calculation
- Keyword density check to identify stuffing or underuse

Images & Media:
- Missing alt text detection with visual element highlighting on the page

Links:
- Internal link analysis: count, anchor text quality, site structure distribution

- Broken link and empty href detection with on-page highlighting
- Excessive link count warnings

Technical & Social SEO:

- Schema.org structured data and JSON-LD detection and type identification
- Hreflang tag review for international SEO and multilingual websites
- HTTPS enforcement and security header analysis
- Page weight measurement and resource count (scripts, stylesheets, fonts)

AI Visibility (GEO/AEO Audit):
- Semantic HTML structure analysis for AI parsing readiness
- llms.txt file detection to help AI systems understand your content
- AI bot access review in robots.txt (GPTBot, ClaudeBot, PerplexityBot, Google-Extended)
- E-E-A-T signal detection: author info, citations, about page, credentials
- FAQ and HowTo schema markup validation for AI-friendly structured data
- Content freshness signals: datePublished, dateModified meta tags and JSON-LD
- Direct answer readiness: question-format headings and FAQ schema pairing
- AI citability score: statistics, data tables, authoritative references, blockquotes
- Content structure for AI: lists, tables, definitions, figures, table of contents
- XML sitemap presence and URL count verification

The only Chrome extension that combines traditional on-page audit with generative engine optimization (GEO) and answer engine optimization (AEO) checks. As AI-powered search platforms like ChatGPT, Google AI Overviews, and Claude become primary information sources, your content needs to be optimized for both traditional rankings and AI visibility. QuickSEO covers both in a single audit.

WHAT MAKES THIS SEO CHECKER DIFFERENT

Plain-English Explanations: This website SEO checker gives you human-readable explanations for every issue, not cryptic error codes. Even if you have never done an SEO audit before, you will understand each problem and why it affects your search rankings.

Step-by-Step Fix Guides: Each issue detected by the on-page SEO checker comes with concrete fix instructions, including code examples where relevant. Written so that even someone editing their first blog post can follow along and improve their page rankings.

Visual Page Highlighting: Click any issue in the SEO audit report to see the problematic element highlighted directly on the web page with a colored overlay. Missing alt text? Click to see which images need attention. Broken heading structure? Every heading lights up on the page.

SEO Score (0-100): The website audit tool calculates a weighted score based on the importance of each factor. Title tags and meta descriptions carry more weight than minor details. Use the SEO score to track progress after making changes.

One-Click On-Page Audit: No account creation, no API keys, no monthly limits. Open the side panel, click one button, and the full SEO analysis report appears in seconds. The checker works on any website you can visit in Chrome.

Categorized & Prioritized: The on page SEO and AI visibility audit results are grouped by category (Page Basics, Content, Images, Links, Technical, AI Visibility) and sorted by severity — critical issues first, minor suggestions last. This audit tool makes it easy to focus on what matters most.
