WordPress

· the world's most popular CMS

WordPress powers around 43% of the web — and most of its SEO issues come from the plugin layer, not the core.

Squarespace

· the design-first hosted website builder

Squarespace makes beautiful sites and handles the SEO basics — clean URLs, automatic sitemaps, SSL, mobile-responsive templates — but its design-first philosophy hides the levers that actually move rankings.

Wix

· the all-in-one site builder used by 200M+ users

Wix had a rough SEO reputation in the early 2010s — slow Velo-rendered pages, separate mobile URLs, and crawler blocks.

Webflow

· the visual-first website builder for designers

Webflow's visual editor gives designers pixel-perfect control — and lets them ship sites that are SEO disasters underneath.

Framer

· the design-to-production website builder

Framer turns designs into live sites with no code, and it ships a surprisingly solid SEO baseline — server-side rendering, automatic sitemaps, clean URLs, and per-page meta controls.

Ghost

· the publishing platform built for writers and newsletters

Ghost is one of the most SEO-friendly platforms out of the box — fast by default, clean semantic HTML, automatic AMP and sitemaps, structured data on posts, and canonical handling that just works.

Shopify

· the largest hosted ecommerce platform

Shopify gives you a fast CDN, automatic image optimization, and PCI compliance — but it locks down robots.

WooCommerce

· the WordPress ecommerce plugin powering millions of stores

WooCommerce gives you full control over your store's SEO — which is exactly why it's so easy to get wrong.

BigCommerce

· the hosted ecommerce platform for growing brands

BigCommerce markets itself as more SEO-friendly than Shopify — editable robots.

Magento

· the enterprise open-source ecommerce platform

Magento (now Adobe Commerce) is built for large, complex catalogs — and that scale is precisely where SEO breaks.

Next.js

· the React framework powering modern SaaS

Nuxt

· the intuitive Vue meta-framework

Nuxt gives Vue developers server-side rendering, static generation, and a clean head-management API — which means it can produce excellent SEO.

React

· the UI library most modern web apps are built with

React itself has no SEO — it's a UI library.

Vu

Vue

· the progressive JavaScript framework

Vue itself has the same SEO trade-offs as React: a vanilla Vue + Vite SPA ships an empty HTML shell to crawlers and renders client-side, leaving little for Google to index.

Gatsby

· the React-based static site generator

Gatsby pre-renders pages to static HTML at build time, which gives it a genuinely strong SEO foundation — crawlers get fully-formed content, fast first paint, and clean URLs.

Astro

· the islands-architecture framework with zero JS by default

Astro starts with a near-perfect SEO foundation: zero JavaScript by default, static HTML output, content collections that map cleanly to URLs, and an official @astrojs/sitemap integration.

How it works

One audit. Every stack's quirks accounted for.

SEOSpectator's audit parses the static HTML response and the rendered DOM (via headless Chrome), so we catch issues that show up in one pass but not the other. Then the category-level scoring weights checks by what actually moves rankings on each platform — schema gaps hit harder on Shopify, hydration mismatches hit harder on React, image alt-text gaps hit harder on Webflow. Same engine. Stack-aware results.

Don't know your platform?
Audit anyway.

The audit works on every URL — CMS, framework, headless, hand-rolled HTML. Paste any link, get 70+ checks in 8 seconds.
