Overview

StaticSEO is a free, open-source SEO tool designed specifically for static websites (including sites managed with Instatic). Instead of relying on client-side JavaScript or third-party tracking scripts at runtime, StaticSEO injects all essential SEO metadata directly into your static HTML files at publish time.

Because every meta tag, canonical URL, social card, and JSON-LD schema block is baked into the raw HTML before deployment, search engine crawlers and social media link previews read your metadata immediately with zero runtime overhead.

Key Highlights & Features

• Core Meta Tags & Indexing Controls: Automatically manages page titles, meta descriptions, canonical URLs, and per-page noindex / sitemap exclusion switches.
• Social Link Previews (Open Graph & X/Twitter): Generates complete Open Graph (og:*) and Twitter/X card metadata with built-in previews so shared links look crisp on Slack, LinkedIn, WhatsApp, Discord, and X.
• Automated JSON-LD Structured Data: Produces clean JSON-LD schema markup for Organizations, WebSites, WebPages, Breadcrumbs, Articles, Services, and FAQs.
• XML Sitemap Generation: Automatically builds and updates sitemap.xml containing only indexable, published pages for Google Search Console and Bing Webmaster Tools.
• Single Source of Truth: Pulls global organization details (business name, address, phone number, hours) from centralized data tables so updates propagate across all pages on publish.
• Page Audits & Content Rules: Checks titles, <h1> tags, image alt attributes, and thin content before publishing, and applies template rules to new entries automatically.
• Staging Safe Mode: Includes a global switch to keep staging or preview deployments out of search indexes until launch.
• Zero Client-Side Bloat: Adds zero browser JavaScript, cookies, or tracking pixels—100% pure static HTML output.

How It Works with Static Websites

1. Configure Global & Content-Type Rules: Set your site-wide defaults, organization schema details, and title/description templates.
2. Audit & Preview Social Cards: Review page-level SEO checks, heading structure, and Open Graph card previews while editing content.
3. Publish Clean Static HTML: On publish, StaticSEO writes <meta> tags, <link rel="canonical">, <script type="application/ld+json"> blocks, and sitemap.xml directly into your static output files.

When to Use It

• Static & Jamstack Websites: When you want comprehensive SEO management (meta tags, JSON-LD, sitemaps, and social cards) baked directly into static HTML without WordPress plugins or client-side JS.
• Client & Agency Projects: Give editors a clear SEO checklist, social previewer, and staging safe-mode without risking broken markup.
• Performance-First Sites: Maintain perfect Core Web Vitals with zero runtime scripts added to visitor browsers.
