Lumina – SEO & GEO

Premium SEO & GEO Analysis Suite – Schema, Technical, Social, Performance & Crawler Intelligence

Lumina is a professional SEO and GEO analysis suite that gives you everything you need to analyze, optimize, and monitor any webpage — directly in your browser, in one click. Whether you're an SEO consultant auditing client sites, a content marketer optimizing articles, or a developer checking technical SEO before launch, Lumina replaces a dozen separate tools with one single, beautifully designed extension. Stop switching between Google Search Console, keyword tools, schema validators, and PageSpeed tabs. Open Lumina on any page and get a complete analysis in seconds. 📊 OVERVIEW & TECHNICAL AUDIT Every time you open Lumina, you get an instant health check of the current page. You'll see the title tag with character count and pixel-width measurement, the meta description with length validation, the canonical URL with a self-referencing check, and the robots directives including both meta robots and X-Robots-Tag headers. The overview also shows word count, language detection, publish date and last modified date. A visual indexability status bar tells you immediately whether the page can be indexed: green means indexable, yellow indicates a canonical mismatch, and red flags a noindex directive. Below that, you'll find HTTPS status, viewport meta, charset detection, and meta refresh checks. The Technical tab goes deeper with a full breakdown of the page's HTTP headers, content security setup, server response characteristics, and resource loading behavior. Everything is color-coded so you can spot problems at a glance without reading through source code. 🔍 GOOGLE SEARCH CONSOLE — REAL DATA, NO EXPORT NEEDED Connect your Google account with one click using secure OAuth2 authentication. Lumina automatically detects your Search Console property — whether it's a URL property or a Domain property — and loads real performance data directly into the extension. The Performance Dashboard shows an interactive SVG chart with clicks, impressions, CTR, and average position plotted over time. You can toggle each metric on or off, choose from preset time ranges (7 days, 28 days, 3 months, 6 months, 12 months) or set a custom date range. Period comparison lets you overlay the previous period or a year-over-year comparison with dashed lines and percentage deltas on each KPI card. The sortable data table shows your top queries, pages, countries, and devices. Click any query to instantly filter the entire dashboard by that keyword. Click a page to filter by URL. Click a country to narrow the data geographically. When DataForSEO is connected, the queries table automatically enriches with real search volume data and 12-month trend sparklines in a visually distinct column, so you can see at a glance which of your ranking keywords actually have significant search demand. Lumina also checks the current page's indexing status via the URL Inspection API, showing whether the page is indexed, when it was last crawled, and which Googlebot version accessed it. Six advanced analysis features are built into the GSC tab, each in an expandable section. Keyword Cannibalization finds keywords that rank on multiple pages of your site, helping you identify internal competition. Winners and Losers compares the current and previous period to highlight which keywords gained or lost the most positions. Page Performance does the same analysis at the page level, showing which URLs gained or lost clicks. Low-Hanging Fruits identifies high-potential keywords where you have many impressions but low CTR, or where you rank on positions 8 through 20 — small improvements here can move you onto page one. Keyword Discovery takes your top GSC queries as seeds, sends them to DataForSEO, and cross-references the results to find new keyword opportunities you don't rank for yet, as well as expansion potential where you rank beyond position 20. Page Comparison lets you compare the performance of two URLs side by side. All data can be exported as CSV or copied to the clipboard for easy integration into reports and spreadsheets. 🔑 KEYWORD RESEARCH — POWERED BY DATAFORSEO A complete keyword research toolkit is built into Lumina as its own dedicated tab. It uses real Google Ads search volume data via the DataForSEO API with full support for Austria, Germany, Switzerland, UK, US, and many more countries. You choose your target country and language for every query. Five research modes cover different use cases. Search Volume and Metrics lets you enter up to 100 keywords and returns the exact monthly search volume, cost-per-click, competition level, and 12-month trend for each one — the same data you'd get from Google Keyword Planner, but without needing a Google Ads account or active ad campaigns. Long-Tail Variations takes a seed keyword and finds hundreds of longer phrases that contain your keyword with additional words, perfect for discovering specific, lower-competition queries. Keyword Ideas discovers related terms from the same product or service category that don't necessarily contain your seed words at all — ideal for content gap analysis and topic expansion. Ranking Keywords shows which keywords the current domain actually ranks for in Google, including the exact SERP position, keyword difficulty score, and search intent classification. Topic Keywords finds keywords associated with the same product and service categories as the current domain, useful for understanding the broader keyword landscape. Every result includes the keyword itself, a 12-month trend sparkline colored green for rising and red for declining trends, the monthly search volume with a visual proportion bar, CPC in local currency, a competition badge (Low, Medium, or High), and where available, a keyword difficulty score and search intent label (Informational, Commercial, Navigational, or Transactional). An exclude filter lets you remove brand keywords, competitor names, or irrelevant terms with a simple comma-separated list, applied to all results in real time. If Google Search Console is connected, a single click imports your top 30 GSC queries as seed keywords for deeper research. Results can be copied to clipboard in a tab-separated format ready for Google Sheets, or downloaded as a CSV file with all available columns. 🏷️ SERP PREVIEW & SIMULATOR Lumina recreates exactly how your page appears in Google search results, matching Google's precise rendering widths: 652 pixels for desktop and 412 pixels for mobile. The preview shows the favicon, site name, breadcrumb URL, three-dot menu icon, title, and description — all rendered with the correct fonts, sizes, line heights, and truncation behavior. On desktop, titles display on one line with ellipsis truncation, and descriptions show two lines. On mobile, titles wrap to two lines and descriptions to three. Toggle between the two views with a single click. The SERP Simulator below the preview lets you edit the title, description, and URL in real-time. Each field has a pixel-based width counter that shows the exact pixel width alongside the maximum, color-coded green for safe, yellow for risky, and red for truncated. This is far more accurate than character-count tools because Google truncates based on pixel width, not character count. Export the preview as a high-resolution PNG image with an optional drop shadow effect. Copy it to the clipboard or download it as a file. These images are perfect for client presentations, SEO audit reports, and social media posts demonstrating optimization results. 🤖 AI-POWERED TOOLS Five AI analysis tools powered by OpenAI use the full page context — content, headings, meta tags, and Google Search Console performance data — to deliver genuinely useful, context-aware recommendations rather than generic SEO advice. The Content Optimizer analyzes your content against target keywords and scores it from 0 to 100. It identifies specific strengths and issues with concrete fixes, checking keyword density, placement across title, H1, meta description, and first 100 words, readability, content gaps, and cannibalization risk. When GSC data and keyword volumes are available, it incorporates real search performance into its recommendations. The Meta-Tag Generator creates three optimized title and description variants targeting your keywords. Each variant comes with a strategy label explaining the approach, a full pixel-accurate SERP preview with its own Desktop and Mobile toggle, editable input fields with live pixel counters, keyword badges showing which target terms are included, and image export with copy and download buttons. Competitor Analysis lets you enter up to three competitor URLs. Lumina fetches their content and compares it against your page across content length, keyword coverage, heading structure, and overall SEO strength, providing a verdict and specific recommendations. The GEO and LLM Simulation tool simulates how ChatGPT, Claude, and Perplexity would interpret your page for a given search query. It scores your page's readiness for generative engine optimization from 0 to 100 and identifies improvements for entity clarity, fact density, and quotability — increasingly important as AI-generated search results become more prevalent. The FAQ Schema Generator extracts question-answer pairs from your page content and generates ready-to-use FAQPage JSON-LD structured data. Copy the raw schema or the complete script tag with one click. 📑 SCHEMA VALIDATION Lumina detects all structured data on the page across JSON-LD, Microdata, and RDFa formats. Each schema object is parsed, displayed in a collapsible detail view, and validated against Schema.org types. The validator also detects conflicts between multiple schema objects, such as duplicate Organization schemas containing different data. An AI-powered Schema vs. Content check goes further by verifying that your structured data actually matches what's visible on the page. It catches issues like product prices in the schema that don't match the displayed price, or business addresses in structured data that differ from what users see — problems that can lead to rich result penalties. 🕷️ CRAWLER INTELLIGENCE See your page through the eyes of search engine bots. The Live Server Check makes a real HTTP request and shows the status code, response headers, response time, redirect chain, and content type. It catches issues like soft 404 errors, unexpected redirects, and missing security headers that affect crawling. The Robots.txt Analysis fetches and parses the site's robots.txt file, showing the rules for every known bot including Googlebot, Bingbot, GPTBot, ClaudeBot, Applebot, and more. A combined table view displays each bot's access status alongside the specific rule that allows or blocks it, making it easy to verify that your crawl directives work as intended. 🔗 LINK ANALYSIS Get a complete inventory of every link on the page: total count, internal versus external breakdown, and nofollow count. The filterable list shows anchor text, destination URL, rel attributes, and link type for each link. The Broken Link Checker tests every link on the page and reports HTTP status codes. A visual on-page highlighting feature overlays colored borders directly on the live page — green for working links, yellow for redirects, red for broken links — with status code badges, so you can see problems in context without switching between tabs. An Internal Link Ranking section shows which pages on your site receive the most internal links from the current page, helping you understand your internal linking structure. 📐 HEADINGS & SEMANTIC ANALYSIS View the full heading hierarchy from H1 through H6 with visual indentation showing the structure. Copy all headings as text or export as CSV. The Semantic HTML Analysis scores the page's use of modern HTML5 structural elements: header, nav, main, article, section, aside, and footer. It detects deprecated elements like font, center, b, and i tags. It checks for empty links, div-based buttons that should be proper button elements, missing ARIA landmarks, skip navigation links, and figure with figcaption usage. Each finding comes with a severity level and recommendation. 🖼️ IMAGES, SOCIAL, PERFORMANCE & TOOLS The Images tab provides a full audit of every image on the page including source URL, alt text, dimensions, file size, and lazy loading status. Filter by missing alt text, missing dimensions, or oversized files to quickly find optimization opportunities. Social and Open Graph analysis shows a visual preview of how the page appears when shared on Facebook, Twitter, and LinkedIn, alongside a complete inventory of all Open Graph and Twitter Card tags with completeness checks. PageSpeed Insights integration runs Google's performance test for both Mobile and Desktop directly from the extension, showing Core Web Vitals scores and detailed performance metrics. The Tools tab provides one-click links to external analysis tools — Google Search Console, PageSpeed Insights, Rich Results Test, Schema.org Validator, W3C HTML Validator, WAVE Accessibility Checker, SSL Labs, Security Headers, BuiltWith, and the Wayback Machine. All links are pre-filled with the current page URL. Search Console links automatically open with the correct property type, whether URL-based or Domain-based. ✨ DESIGN & CUSTOMIZATION Lumina features a clean, modern interface with both light and dark mode. The tab order is fully customizable — drag and drop to rearrange tabs, and toggle visibility to hide the ones you don't need. A 10-second data cache means you can close and reopen the popup without losing your analysis or triggering new API calls. Every analysis in Lumina can be exported: CSV downloads, clipboard copy, image exports for SERP previews, and Markdown exports for AI tool results. The extension is designed to fit naturally into your existing workflow, whether you're building client reports, optimizing your own content, or conducting competitive research. 🔒 PRIVACY Lumina analyzes pages locally in your browser.
