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. > [!TIP] > > 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 whether AI assistants like **ChatGPT** and **Google AI Overviews** mention or cite your brand when buyers ask questions about your category. * **What it checks** - Spyro AI formulates 5 tailored buyer-intent prompts for your website and runs them live across **ChatGPT** and **Google AI Overviews** (10 checks total). It also crawls up to 20 pages of your website to evaluate technical SEO health. * **Mentions vs citations** - separates text that names your brand (**mentions**) from clickable source links pointing to your domain (**citations**), and classifies answer sentiment as positive, neutral, or negative. * **Competitor share of voice** - benchmarks your brand against up to 3 competitors (suggested automatically or chosen by you) to see who wins target category queries. * **What you get** - an overall **AI visibility score** (0% to 100%), per-engine breakdown (ChatGPT vs Google AI Overviews), cited source pages, competitor rankings, a 20-page technical SEO health snapshot, and a private interactive dashboard valid for 30 days at `/free-report/[token]` with one-click PDF download. * **How to use it** - enter your website, confirm your market location and competitors, verify with a quick 6-digit email code (no password, no credit card required), and get your live results in seconds. > [!TIP] > > Free AI visibility checks are limited to one fresh report per domain every 24 hours. Re-entering your domain within that window reopens your saved report. ### 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. **1. Click Download PDF** A small box opens, offering free weekly SEO & GEO updates for your site. **2. Add your email - or skip it** Enter your email to subscribe, or choose **Skip and download**. Either way, your PDF downloads right away.
