SEOini is a powerful, privacy-first browser extension designed for SEO specialists, web developers, and product managers. Get a comprehensive, technical breakdown of any webpage in a single click—directly in your browser, without switching tabs or waiting for heavy desktop software.

Content Structure: Clear hierarchical view of H1–H6 tags. Indexing & Social: Canonical tags, lang attributes, Open Graph protocols, and Twitter Cards. Structured Data: Comprehensive verification of Schema.org markup. Links & Images: Deep scan of internal/external links, image ALT texts, and lazy-loading status. 🌐 Server Response & HTTP Headers Analysis Go beyond the visible HTML. Detect critical backend configurations that regular tools miss: Real-time HTTP status codes and complex redirect chains. X-Robots-Tag and Link rel="canonical" headers hidden inside HTTP responses. Catch the #1 reason pages drop out of Google's index before troubleshooting HTML. ⚡ SSR vs. CSR Diff (Unique Feature) Bridge the gap between server-side and client-side rendering. SEOini compares raw HTML against JavaScript-rendered DOM to detect: Hidden discrepancies in Titles, H1s, and Canonical tags. Schema.org markups or meta robots that only appear after JS hydration—saving your site from being invisible to Google's first crawl phase. 🤖 One-Click "View as Googlebot" Instantly switch your current tab's User-Agent to Googlebot Smartphone and reload the page. Analyze exactly what Google's mobile-first index sees without leaving your workspace. 📊 Background Competitor Gap Analysis Audit the top 10 SERP rivals for your target keyword in the background. Receive a structured, actionable gap report highlighting where your on-page strategy falls short compared to competitors. 📦 Batch Audit Mode (Up to 30 URLs) Streamline your workflow by pasting up to 30 URLs at once. SEOini audits them automatically and aggregates the data into a clean, scannable table. 📈 Local History & Field-by-Field Diff Every audit is safely stored in your local storage—no registration or login required. Track optimization progress with intuitive score sparklines over time. Compare performance using a detailed, field-by-field "Before vs. After" diff tool. 📋 Instant Export & Copy to Clipboard Export your audit results as a beautifully formatted table. Paste data directly into Google Sheets, Notion, Excel, or any Markdown editor with zero formatting issues. 🔒 Privacy-First Architecture No intrusive permissions upon installation. Host access is requested strictly on-demand (e.g., when running competitor analysis) with transparent prompts. Your data belongs to you: audits are saved to the cloud only if you choose to log in. 🌐 MULTILINGUAL SUPPORT Fully localized and supports: English, Russian, and French. 💡 Why choose SEOini? Most SEO extensions only scrape basic HTML. SEOini digs deeper into modern web architecture (JavaScript rendering, HTTP headers, and mobile bot simulation) giving you an unfair advantage in technical SEO optimization.
