Semaphore SEO

Analyse SEO GA4 & GSC en direct sur votre site.

Stop wasting precious minutes switching from Google Analytics 4 to Google Search Console to evaluate page performance. Transform your browser into a live, professional SEO cockpit. Semaphore merges your traffic data (GA4), Search Console visibility (GSC), competitor SERP analysis, and on-page technical audits into a single, smooth, and persistent Side Panel. Built for site publishers, consultants, and agencies, Semaphore automates key metrics extraction and highlighting so you can make data-driven decisions instantly. KEY FEATURES 🔴 LIVE GOOGLE ANALYTICS 4 (GA4) No more complex searches in the GA4 interface. Semaphore instantly displays traffic charts for the exact page you are currently visiting. • Dynamic Timeframes: Analyze traffic for today, yesterday, 7 or 30 days, and go up to 1 year back (90 days, 6 months, and 1 year) to monitor long-term trends. • User vs. Session comparisons at a glance. • Top Acquisition Sources (Organic, Direct, Referral) to quickly see where your audience comes from. 🔴 GOOGLE SEARCH CONSOLE (GSC) & CANNIBALIZATION Visualize the real-world performance of your URL in Google search results without leaving your site. • Top 10 Queries: Track the exact keywords driving traffic to the active page. • Page-Level Metrics: Direct access to Clicks, Impressions, and Average Position (with adjustable history up to 1 year). • Cannibalization Detector: Automatic alerts if other pages on your site are fighting for the same primary keyword. 🔴 STRUCTURED DATA (SCHEMA.ORG & JSON-LD) No need to inspect the page source code or copy-paste URLs into Google's Rich Results Test tool. • Instant Detection: Semaphore automatically identifies all structured data embedded on the page. • Decoded JSON-LD payload: View and review your Schema.org structures (Product, Article, FAQ, LocalBusiness, Breadcrumb...) in a clean, human-readable format. • Quick validation: Instantly spot missing properties or syntax errors. 🔴 SEMANTIC AUDIT & INTERACTIVE HN STRUCTURE Analyze the editorial architecture of your page in real time. • Smart HN Headings Tree: Renders a color-coded headings outline (H1 to H6) with automatic alerts for structural issues (missing H1, duplicate H1s, hierarchy jumps like H2 to H4). • Visual Locator: Click any heading in the tree to automatically scroll to and visually highlight the targeted element. • Keyword Frequency: A tag cloud of the top 10 terms (longer than 4 letters) repeated on the page to verify semantic optimization. 🔴 IMAGE AUDIT (ALT TEXT) & LINK PROFILE ANALYSIS Take control of your on-page elements without opening the developer code inspector. • Image Audit: List all images with instant visual highlighting on click for those missing Alt text (critical for Google Images SEO). • Tri-Color Link Sorting: Automatic counter and classification of links into 3 categories (internal, external, and affiliate) displaying anchor texts, target URLs, and relationship attributes (nofollow, sponsored). 🔴 USER BEHAVIOR TRACKING (Exit Links & Live Clicks) Visualize how visitors interact with your links. • Live Link Clicks: Displays the exact number of real user clicks next to each audited link (integrated with GA4 event tracking). • Exit Links: Top 10 external links clicked that lead visitors away from your active page. 🔴 E-E-A-T SIGNALS & OPEN GRAPH Measure the trust value and social optimization of your website. • E-E-A-T Trust Signals: Automatic scan for trust indicators (author links, terms/policies pages, contact page, legal mentions, and HTTPS). • Social Preview: Preview social sharing cards (og:title, og:description, og:image) for networks. 🔴 GOOGLE SERP ANALYZER When searching on Google, the SERP tab activates to help you break down the competition: • Ordered list extraction of all organic search results. • Instant display of exact ranking positions, titles, target URLs, and snippets for any competitor. 🔴 SEO PROMPT GENERATOR FOR AI (AUTOMATED COPY-PASTE) Prepare your audit data prompts for AI in 1-click in a transparent and secure way. • How it works: Semaphore extracts page metrics (headings, GA4 traffic, GSC keywords, JSON-LD schemas) and compiles them into an optimized prompt. The extension copies it to your clipboard and opens the AI of your choice (ChatGPT, Claude AI, or Perplexity). You just have to paste (Ctrl+V) it to start the audit! • Privacy-First: No API keys to configure, no extra usage fees. Your audit data remains local inside your clipboard and never passes through any middleman server. 🔴 INTELLIGENT "ZERO CONFIG" MULTI-SITE ENGINE • Domain Detection: Log in securely once via your Google account. The extension automatically detects your active domain and queries the correct GA4/GSC property when switching tabs. • Quick Tools: Direct, pre-filled links using the active URL pointing to PageSpeed Insights, Wayback Machine, Ahrefs Backlinks, and Schema Validator.
