Pre-rendered static HTML
Your content lives directly in the source code. Visitors and search bots get fully rendered pages immediately, eliminating common single-page app indexing issues.
Build a fast, SEO-friendly static website
Deliver lightning-fast pages and boost your visibility in Google Search and AI Overviews. Fine-tune metadata, readable URLs, sitemaps and image compression directly in Publii. Publish pure static HTML that search engines can crawl instantly-no client-side JavaScript required.
Take full control of your SEO
Manage metadata, indexing rules, URLs and your sitemap from a single interface. Set global defaults across your site and easily override them on individual posts.
Cut page weight and bandwidth
Minify code, generate responsive layouts and serve next-gen WebP or AVIF images. Your hosting delivers lightweight static assets without server database overhead.
Control titles, metadata and indexing
Set default titles and descriptions for your entire site, then fine-tune them for individual posts and pages. Manage key SEO settings in the app without touching raw HTML.
Use dynamic patterns like %posttitle | %sitename to keep title tags consistent. Search engines will use your custom titles and meta descriptions or extract relevant page excerpts.
Apply noindex tags to selected pages or your entire site to keep them out of search results. This controls search indexing without restricting public access to the URL.
Help search engines discover and understand your content
Provide clean URLs and descriptive metadata for every page. Keep an accurate XML sitemap and craft eye-catching link previews when your content is shared online.
Enrich your articles with structured data
Give search engines explicit context about article titles, authors and publish dates. Publii’s built-in JSON-LD support adds schema markup automatically in compatible themes, and developers can easily extend it.
Structured data aligns directly with on-page content, helping qualify your pages for prominent Rich Snippets in Google search results.
Publish clean, human-readable URLs
Create descriptive slugs and organize posts, tags and authors using clean URL prefixes. Stick with the standard .html extension or enable Pretty URLs for modern addresses like /blog/field-notes/.
When updating existing live URLs, configure 301 redirects on your server to preserve SEO authority and avoid broken links.
Configure URLs and prefixes
Generate XML sitemaps automatically
Enable automatic sitemap generation and Publii updates your XML file with every publish. Choose to include or exclude tag pages, author archives, pagination or external images.
Your sitemap helps search bots crawl new content quickly, working hand-in-hand with your internal linking structure.
Customize your sitemap
Make shared links stand out on social media
Use Open Graph and Twitter Card tags to control titles, descriptions and preview thumbnails. Add a high-resolution featured image so your posts look sharp on Facebook, X, LinkedIn and messaging apps.

Your server delivers pre-built static files without executing PHP scripts or querying SQL databases. Leverage Publii's built-in speed features to slim down asset sizes and boost Core Web Vitals scores.
Lightweight, responsive themes
Official Publii themes rely on semantic HTML, clean CSS and vanilla JavaScript. Layouts adapt smoothly to any screen without dragging in bulky front-end libraries or bloated JavaScript runtimes.
Asset weight, third-party scripts and hosting speed still influence Core Web Vitals, so be sure to audit your live site regularly.
