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.

Shopify

· the largest hosted ecommerce platform

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

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.

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.

Next.js

React

· the UI library most modern web apps are built with

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

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.

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.
