The **Free Tools Hub** is a collection of quick checks you can run on any website - no account, no email, no credit card. Just type in a web address and get an instant read on how your site is doing on Google and inside AI assistants. Find it at [spyro.app/free-tools](https://www.spyro.app/free-tools). ## Why use it It's the easiest way to see what Spyro can find before you sign up. Run a check in seconds, spot what's holding your site back, and get a clear list of fixes - all for free. ## What's in the hub ### SEO & GEO website audit One scan that grades both your traditional **SEO** health and your **GEO readiness** - whether AI assistants like ChatGPT and Gemini can find and mention you. * **What it checks** - your website, page by page. * **What you get** - separate SEO and GEO scores, the full list of issues, and fixes ranked by how much they matter. You get one fresh audit per site every 24 hours. Re-run within that window and you see the saved report - and can sign up for free weekly updates. ### AI-visibility checker Finds out how ready your site is to be **mentioned** by AI search and answer tools. * **What it checks** - reads a sample of your public pages and looks at how clearly your content is structured. * **What you get** - an overall visibility score across six signals, plus your strengths, your gaps, and the actions that will help most. ### AI-crawler & robots checker Confirms that AI bots are actually allowed to read your site. If they can't read you, they can't mention you. * **What it checks** - the rules your site uses to allow or block bots like GPTBot, ClaudeBot, PerplexityBot, and Googlebot. It also catches **silent blocks** - cases where a bot is turned away even though the rules say it's welcome. * **What you get** - an access score, a list of which AI tools can read you, and a ready-to-paste set of rules that opens your site up to AI answer engines. ### Schema-markup validator Checks the hidden labels on your pages (called structured data) that help Google and AI understand what each page is about. * **What it checks** - a sample of your pages, grouping the labels by type and checking each one for missing or broken details. * **What you get** - a health score, a breakdown of what's wrong by type, and priority fixes. ### Meta-snippet preview Shows how your page will look in Google's search results before you publish. * **What it checks** - type a title and description, or paste a page address to pull in its current ones. Everything runs right in your browser. * **What you get** - a live preview on desktop and mobile, a score, a warning if Google will cut your text short, and copy-ready tags. ## Save and share your report Most of these checks let you **download a PDF** of your results. A small box opens, offering free weekly SEO & GEO updates for your site. Enter your email to subscribe, or choose **Skip and download**. Either way, your PDF downloads right away.
