• Improve meta descriptions for AI - Write clear, concise meta and Open Graph descriptions that answer 'what does this company do?' in 10-30 words. AI systems rely heavily on these to summarize your brand. (impact: high, effort: quick_win)
• Add structured data and Open Graph tags - Add JSON-LD structured data (Organization, FAQ schemas) and complete Open Graph tags (og:title, og:description, og:image, og:type). This helps AI systems and social platforms accurately represent your brand. (impact: high, effort: moderate)
• Add custom brand typography - No custom fonts were detected on your website. Choose a heading font and body font using a service like Google Fonts to establish typographic brand identity. (impact: medium, effort: quick_win)

AI visibility

Sto scores 32/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.

Sto has a weak AI-visibility profile at 32/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (37/100) and its weakest is trust (22/100). It benefits from a Wikidata knowledge-graph entry and open access for AI crawlers (GPTBot, ClaudeBot, etc.). The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data, a low Moz Domain Authority of 35/100 and thin schema.org structured data. In a live check, Claude could already identify Sto from memory (October 2026) - a sign these signals are paying off.
