ON-PAGE ARCHITECTURE
The Mathematical Structure of Verified Rankings
Success in search begins with clean, semantic architecture. SEO Expert audits the invisible skeleton of your page.
Canonicalization Logic
Duplicate content is the silent killer of rankings. We strictly verify `<link rel='canonical'>` to ensure it matches the current URL, protecting your link equity from being diluted across query parameters or protocol variations.
Meta Tag Precision
Google rewrites 60% of titles, but control matters. We audit Title (50-60 chars) and Description (150-160 chars) for pixel-perfect display in SERPs. We also detect `robots` meta directives to prevent accidental de-indexing.
Heading Hierarchy (H1-H6)
Screen readers and crawlers read your headers to understand context. We visualize your H1-H6 structure as a nested tree, instantly highlighting missing H1s, duplicate H1s, or illogical jumps (H2 to H4) that confuse search algorithms.
Image Alt Text & Accessibility
Alt text is a ranking vector for Google Images. We scan every `<img>` tag to ensure descriptive text exists, flagging generic filenames and empty attributes that miss valuable keyword opportunities.
VISUAL DEBUGGER
X-Ray Vision for your DOM
Stop guessing. See exactly how crawlers interpret your code with our real-time visual overlays.
Focus Mode (Heading Map)
Instantly visualize the skeleton of your content. We overlay high-contrast badges (H1-H6) directly on your page elements, making broken hierarchies and empty headers impossible to miss.
Link Radar
A heads-up display for your link juice. We color-code every link in the viewport: Green for internal, Orange for external, and Red for nofollow/sponsored. Spot broken internal linking strategies in seconds.
Image & Media Audit
Debug CLS and Accessibility visually. We highlight images lacking dimensions (causing layout shifts) and red-box any image missing 'alt' text. Perfect for quick QA before publishing content.
TECH STACK & SECURITY
Know What Powers the Web
SEO is no longer just HTML. It's React, Next.js, and server config. We strip the paint capability to see the engine.
Deep Stack Detection
We go beyond 'WordPress'. We detect Next.js 14, Astro 5.0, Shopify Liquid, and WordPress 6.x. Knowing the stack helps diagnose specific technical SEO pitfalls.
Security Header Analysis
Security affects trust. We validate essential headers like HSTS, CSP (Content-Security-Policy), X-Frame-Options, and Permissions-Policy to ensure your site is secure and trustworthy.
AI-Ready (llms.txt)
Prepare for the future of search. We validate llms.txt, robots.txt, and AIUserAgent directives, giving you control over how Large Language Models consume specific content.
PERFORMANCE (RUM)
Google's Measuring Stick for UX
Passing Core Web Vitals is mandatory. We provide real-time, field-data equivalent metrics using the PerformanceObserver API.
LCP & INP
Measures loading speed and interactivity. We track Largest Contentful Paint and the new Interaction to Next Paint metric, helping you identify exactly which scripts or elements are lagging your UI.
CLS (Layout Shift)
Visual stability matters. We track layout shifts in real-time, identifying exactly which DOM elements (ads, images without dimensions) are causing the page to jump so you can fix them.
TTFB & DOM Weight
Bloat slows down mobile crawling. We measure Time to First Byte and count DOM Nodes. We flag uncompressed images and heavy hydration states that consume user data and crawl budget.
