Analysis Tabs

Overview

Get a panoramic view of your page's SEO status in seconds. This tab presents an executive summary with evaluations of all categories organized by priority level, highlighting the 5 critical issues requiring immediate attention.

Basic SEO

Verify that your page meets the essential fundamentals that search engines need to properly understand and index your content. This tab evaluates critical elements like title tags, meta descriptions, heading structure (H1-H6), canonical URLs, robots directives, Open Graph for social media, mobile viewport, and language declaration.

Performance

Measure how fast your page loads using Google's official Core Web Vitals. Includes LCP Breakdown 2025: complete breakdown of LCP phases (TTFB, Resource Load Delay, Resource Load Duration, Element Render Delay) with phase-specific recommendations. Evaluates LCP, INP (2024 interactivity metric), CLS (visual stability), FCP, TTFB, and detects blocking resources.

Technical Review

Ensure search engines can crawl, understand, and index your site correctly. Includes 2025 security analysis: COOP (Cross-Origin-Opener-Policy), CORP (Cross-Origin-Resource-Policy), HSTS, Brotli/Gzip compression, HTTP headers for performance and SEO. Evaluates URL structure, HTTPS, mobile optimization, robots.txt and XML sitemap.

Content

Evaluate whether your content is sufficient, relevant, and well-structured to satisfy search intent. Includes detection of links without rel="noopener" with specific domain listing for trust review. Analyzes word count, top keywords, text/HTML ratio, paragraph structure, readability, and internal/external links with rel attributes.

Images

Optimize your images to improve accessibility and performance. Identifies images without alt text, legacy formats (convert to WebP/AVIF for 25-35% less weight), oversized images (detects images 2× larger than display size). Includes LCP lazy-load warning 2025: detects if LCP image has lazy loading (hurts performance). Evaluates lazy loading and HiDPI support.

AI SEO

Prepare your content for AI-powered searches and LLMs. Verifies Schema.org JSON-LD with syntax validation, types (Article, Product, LocalBusiness, Organization, etc.), completeness (required vs optional properties). Detects llms.txt for LLMs (GPT, Claude, Perplexity), AI robots (GPTBot, Google-Extended, CCBot, Anthropic-AI), Content Licensing (CreativeCommons, TDMRep), and Rich Results eligibility.

Accessibility

Ensure WCAG 2.2 compliance (ISO Standard 2025). Verifies color contrast (Success Criterion 1.4.3 AA/AAA), forms with labels and ARIA, roles/attributes/landmarks (SC 1.3.1, 4.1.2), duplicate IDs (WCAG 4.1.1 Failure F77). Includes Interactive Highlights 2025: click to highlight elements with contrast issues, inputs without labels, duplicate IDs, and missing ARIA. Evaluates keyboard navigation and touch targets.

International

Expand your reach to multiple countries and languages with the correct configuration for international SEO. This tab verifies the lang attribute declaration, implementation of hreflang tags to indicate language/region alternatives, and content localization quality.

E-commerce

Maximize visibility in Google Shopping with 2025 schemas. Analyzes Product schema (name, description, image, SKU, brand), offers (price, priceCurrency, availability, priceValidUntil), reviews (aggregateRating, reviewCount). Includes 2025 schemas: OfferShippingDetails (costs, times, regions), MerchantReturnPolicy (return policies), LoyaltyProgram (new 2025), and Google Store Widget (physical locations in results).
