Frequently Asked Questions

Yes. Smart SEO Booster is 100% free and released under the GPLv2 licence, with no premium tier, paywalls, or upsells. Every feature — schema, XML sitemaps, meta tags, breadcrumbs, redirects and AI/GEO SEO — is included at no cost.

Yes. It offers the core SEO features most sites need — schema, sitemaps, meta automation, breadcrumbs and social cards — in a lightweight, no-upsell package, and includes one-click migration so you can import your settings from Yoast SEO or Rank Math.

Smart SEO Booster outputs 14 JSON-LD schema types including Article, BlogPosting, Product, Recipe, Event, HowTo, FAQ, Local Business and more — automatically, and in the page footer for minimal performance impact.

Yes. It includes AI/GEO SEO features such as an llms.txt file and AI-crawler opt-out controls, helping your content be understood and cited correctly by AI answer engines like Google AI Overviews, ChatGPT and Perplexity.

No. Smart SEO Booster is built to be lightweight — it uses minimal hooks and outputs schema only where needed, so it adds SEO capability without the bloat of heavier plugins.

Enable Serve an llms.txt file under Smart SEO → Settings → AI & GEO. The file is generated from your published content and served at /llms.txt, so it stays current as you publish instead of going stale like a hand-written one. If it does not load, visit Settings → Permalinks and click Save once to flush your rewrite rules.

Turn on Ask AI crawlers not to train on this site under Smart SEO → Settings → AI & GEO. This adds robots.txt rules for GPTBot, Google-Extended, ClaudeBot, CCBot and others. Two things worth knowing: Google-Extended controls Gemini training only and has no effect on your Google Search rankings, and blocking training crawlers can also reduce how often AI assistants cite your site — so it is worth deciding deliberately.

Yes. Smart SEO → Page Speed runs a Google PageSpeed Insights check on any URL of your site and reports Performance, SEO, Accessibility and Best Practices scores alongside Core Web Vitals (LCP, CLS and INP), rated against Google's thresholds. It uses real-user CrUX field data where Google has it and lab data otherwise. No API key is required, though you can add a free one for higher-volume checks.

Add the FAQ (Smart SEO) block in the block editor and fill in your questions and answers. It renders an accessible accordion on the front end and outputs FAQPage JSON-LD automatically, which is what Google reads for FAQ rich results. A matching How-To block outputs HowTo schema the same way.

Yes. It integrates with WooCommerce, supports posts, pages and custom post types, and provides native Gutenberg blocks and an editor sidebar with live previews, alongside classic-theme compatibility.

Yes. Smart SEO Booster includes a one-click importer to bring your titles, meta descriptions and settings across from Yoast SEO and Rank Math, so switching is quick and safe.

Support is available through the WordPress.org support forums. For bug reports and feature requests you can also use the GitHub repository, or contact the developer directly.
