SEOWiser — SEO & AI Visibility Analyzer

SEOWiser is the most complete free on-page SEO and AI visibility audit tool available as a Chrome extension. In a single click, it analyzes the page you are currently viewing and generates a structured, scored report across five critical dimensions: AI Visibility, AI Bot Access, Schema Markup, Content Quality, and Technical SEO. Think of it as Lighthouse, an SEO crawler, and an AI readability analyzer — merged into one clean, lightweight popup that lives right in your browser. Whether you are an SEO professional auditing client websites, a content marketer optimizing blog posts for AI search engines like ChatGPT, Perplexity, and Claude, or a developer checking technical health before deployment — SEOWiser gives you instant, actionable intelligence without leaving the tab you are working on. No account required. No data sent to any server. Fully client-side. Free. ───────────────────────────────────────────── ⚡ WHY SEOWISER EXISTS ───────────────────────────────────────────── SEO in 2025 has two audiences: traditional search engines like Google, and AI-powered answer engines like ChatGPT Search, Perplexity, Claude, and Google AI Overviews. Most SEO tools were built before AI search existed. They check title tags and meta descriptions, but completely ignore whether your content is actually readable and accessible to large language models (LLMs). SEOWiser was built from the ground up to audit both worlds simultaneously. It checks whether your content ranks well for humans AND whether AI bots can discover, read, and cite your content. In the era of generative search, this is no longer optional — it is the new baseline for competitive SEO. ───────────────────────────────────────────── 📊 OVERALL SCORING SYSTEM (100 POINTS) ───────────────────────────────────────────── Every page receives an overall score out of 100, calculated as a weighted composite across five categories: AI VISIBILITY — 40 points AI ACCESS — 20 points SCHEMA MARKUP — 10 points CONTENT QUALITY — 20 points TECHNICAL SEO — 10 points The score is color-coded and graded: ✅ 85–100: Excellent ✅ 70–84: Good ⚠️ 55–69: Fair 🔶 40–54: Poor 🚨under 40: Critical Each category breaks down into individual sub-checks with their own mini-scores, so you always know exactly where points are being lost and what to fix first. ───────────────────────────────────────────── 🧠 AI VISIBILITY (40 POINTS) — THE HEADLINE FEATURE ───────────────────────────────────────────── This is the category most SEO tools ignore entirely. AI Visibility measures how well large language models — the engines powering ChatGPT Search, Perplexity, Google AI Overviews, Claude, and Bing Copilot — can actually read, understand, and cite your content. AGENT VIEW vs. HUMAN VIEW SEOWiser renders two separate views of your page: → Agent View: The raw text extracted from static HTML — exactly what AI crawlers like GPTBot and ClaudeBot see when they fetch your page without executing JavaScript. This is the version that gets indexed and cited. → Human View: The rendered text visible to actual users in the browser after JavaScript execution. If these two views differ significantly, you have a hidden content problem. Content buried in JavaScript-rendered components, lazy-loaded sections, tab panels, or accordions is invisible to AI bots even if your human users see it perfectly. SEOWiser detects and flags every one of these discrepancies. AI READABILITY SCORE Calculated using the Flesch Reading Ease formula, the AI Readability Score measures how easily an LLM can parse your writing. Long, complex sentences and dense jargon reduce this score. Clear, well-structured prose increases it. AI models are more likely to quote, summarize, and cite pages with higher readability scores. Score ranges: 70–100: Easy — ideal for AI citation 60–69: Fairly Easy — good 50–59: Average — room to improve 30–49: Difficult — needs work 0–29: Very Difficult — high risk of being skipped by AI summarizers HIDDEN CONTENT DETECTION SEOWiser automatically scans the page for content that is technically present in the DOM but invisible or inaccessible to AI crawlers: Collapsed accordions (details/summary elements not open by default) Hidden tab panels (aria-hidden="true", .tab-pane:not(.active)) Lazy-loaded images and sections (data-src, loading="lazy") CSS display:none elements containing substantial text JavaScript-triggered visibility states Each hidden element type is flagged with a specific warning and a recommended fix, such as adding the "open" attribute to details elements so their content appears in raw HTML. CONTENT STRUCTURE ANALYSIS Beyond readability, SEOWiser maps the structural clarity of your content for AI consumption: FAQ sections present (dramatically increases AI citation probability) List usage (ordered and unordered lists signal structured information) Paragraph count and density Table and video presence ───────────────────────────────────────────── 🤖 AI ACCESS (20 POINTS) ───────────────────────────────────────────── Even the most readable, well-structured content is worthless for AI search if the bots are blocked from crawling it. SEOWiser fetches and parses your site's robots.txt in real time and reports the access status for every major AI crawler individually.
