The script runs once, extracts the data, and is immediately discarded. No persistent background processes. No memory bloat. No tracking. COMPLETE FEATURE BREAKDOWN Overview Tab The Overview tab is your command center for quick SEO health checks. It displays the most critical on-page SEO elements at a glance so you can identify issues in seconds rather than minutes. Page Title extraction with character length validation. The optimal title length for Google search results is between 50 and 60 characters. The extension color-codes the status green for optimal, yellow for suboptimal, and red for missing titles. One-click copy button included. Meta Description extraction with character length validation. The optimal description length is between 140 and 160 characters. Same color-coded feedback system with one-click copy functionality. Canonical URL detection with automatic self-referencing match verification. The extension compares the canonical tag against the current page URL and alerts you if they point to different locations, which could indicate duplicate content configuration issues. Indexability status detection that reads the robots meta tag and googlebot meta tag to determine if the page is set to index, noindex, follow, or nofollow. Clear visual badges make it instantly obvious whether Google can see and crawl the page. Quick stats grid showing total word count, page language attribute, total number of images, and total number of links on the page. JSON-LD Schema Markup detection that identifies every structured data type implemented on the page. Supports all common schema types including Article, LocalBusiness, Product, FAQ, BreadcrumbList, Organization, WebPage, HowTo, Recipe, Event, VideoObject, and more. Properly handles nested graph structures, arrays, and multi-type schemas used by popular plugins like Yoast SEO, Rank Math, and Schema Pro. Indexability Conflict Alert system that monitors for contradictions between your robots directives and canonical tags. If a critical conflict is detected, a pulsing red warning banner appears at the top of the Overview tab directing you to investigate further. Headings Tab Proper heading structure is one of the most important on-page SEO factors. Search engines use headings to understand the content hierarchy and topical relevance of your page. This tab gives you complete visibility into the heading architecture. Full heading hierarchy displayed in document order from H1 through H6. Each heading level is color-coded with a distinct visual tag for instant recognition. Heading count distribution bar showing how many of each heading level (H1, H2, H3, H4, H5, H6) exist on the page. This helps you quickly spot structural imbalances. Click-to-scroll navigation that transforms your heading list into an interactive table of contents. Click any heading in the list and the live webpage will smooth-scroll directly to that heading with a blue highlight animation that lasts 3 seconds. This is incredibly useful for auditing long-form content with 3,000 or more words. Automatic warnings for missing H1 tags, which is a critical SEO error, and for multiple H1 tags on the same page, which is a common structural mistake. Images Tab Image optimization is a frequently overlooked SEO factor that directly impacts both search rankings and accessibility compliance. This tab audits every image on the page. Complete inventory of every image element on the page with its source URL displayed. Alt text audit that checks each image for the presence of an alt attribute. Images with alt text are shown normally. Images missing alt text are flagged with a yellow warning border and red text indicator. Summary statistics showing total image count and how many images are missing alt attributes, giving you an instant pass or fail verdict. Links Tab Internal and external linking strategy is fundamental to SEO performance. This tab provides deep link intelligence for the current page. Complete link inventory showing every anchor element on the page with its destination URL and anchor text. Internal versus external link classification with color-coded visual indicators. Internal links are marked green. External links are marked blue. Visual ratio bar showing the proportional distribution of internal and external links at a glance. Nofollow link detection with a red badge indicator on any link carrying the rel nofollow attribute. Built-in Broken Link Checker that scans up to 50 unique links on the page for HTTP errors. Click the "Run Check" button and the extension will test each link with a real-time progress bar. It reports 404 not found errors, timeout failures, redirect chains, and mixed content warnings where HTTP links appear on an HTTPS page. Results are grouped by severity with broken links shown first. Social Tab Social media sharing optimization directly impacts click-through rates when your content is shared on platforms like Facebook, LinkedIn, Twitter, and WhatsApp. This tab shows exactly how your page will appear when shared. Open Graph (OG) tag extraction for og:title, og:description, og:image, og:url, og:type, and og:site_name. Each field has a one-click copy button. Twitter Card tag extraction for twitter:card, twitter:title, and twitter:description. Live Social Preview card that renders a visual mockup of how your page will appear in a social media feed, complete with the OG image, title, description, and site name. If no OG image is set, the preview hides the image area so you can see exactly what your audience will see. Speed Tab Page speed is a confirmed Google ranking factor. This tab gives you instant performance data pulled directly from the browser Performance API without needing to visit any external tool. Time to First Byte (TTFB) measurement showing how quickly the server responded to the browser request. Color-coded green for under 200ms (excellent), yellow for under 600ms (acceptable), and red for anything slower. DOM Interactive time showing how quickly the page became usable and clickable for the visitor. Full page load time measurement from initial request to the load event completion. Total resource count showing how many individual HTTP requests the page made. Visual resource breakdown chart showing the distribution of requests by type including scripts, stylesheets, images, fonts, API fetch calls, and XMLHttpRequests. Each type is displayed with an icon, a proportional bar, and an exact count. Indexability Conflict Detector that performs an intelligent cross-check of all indexing signals on the page. It detects contradictions such as a page having noindex set but also having a self-referencing canonical tag, robots meta and googlebot meta having conflicting directives, nofollow being set on a page with many internal links, and missing canonical tags. Each conflict is graded by severity (high, medium, low) with specific explanations. SERP Tab The SERP Snippet Editor lets you see and optimize exactly how your page will appear in Google search results before making any changes to your actual website. Live Google Search preview rendered in a white card that looks exactly like a real Google search result, complete with the URL breadcrumb, blue clickable title, and grey description text. Desktop and Mobile toggle that switches the preview between desktop width and mobile width so you can check for text truncation on both devices. Interactive title editor with a real-time character counter (target: 50 to 60 characters) and a pixel-width progress bar that changes from blue to green when optimal and turns red when the text will be truncated by Google. Interactive description editor with a real-time character counter (target: 140 to 160 characters) and its own pixel-width progress bar. Automatic truncation preview that adds an ellipsis to the preview text when your title or description exceeds Google display limits, so you can see exactly where the cutoff happens. One-click copy buttons for both the optimized title and description so you can paste them directly into your CMS, WordPress, Shopify, or any other content management system. Reset button to restore the original title and description from the page if you want to start over. Tools Tab Quick launch buttons that open popular SEO testing tools in a new tab, pre-filled with the current page URL so you do not have to copy and paste anything. Google PageSpeed Insights for Core Web Vitals performance testing Google Rich Results Test for structured data and schema validation Google Mobile Friendly Test for responsive design verification Wayback Machine for viewing historical versions of the page Security Headers scanner for HTTP security header analysis Google Index Check that searches Google for the exact URL to verify if the page has been indexed WHO IS THIS FOR SEO professionals and consultants who audit multiple client websites every day and need a fast, reliable, and free tool that works instantly Digital marketing agencies that need quick on-page quality checks before delivering audit reports or publishing content for clients Web developers and front-end engineers who want to verify meta tags, schema markup, canonical tags, and heading structure during development and staging Content writers and editors who need to check title length, description length, heading structure, and image alt text before hitting publish Freelancers and solo marketers who want a lightweight, professional-grade alternative to expensive SEO software suites like
