Moz Domain Authority 63/100 vs category average 38 / leader 95 - a strong backlink profile, so AI systems frequently encounter mentions of the brand.

Startseite appears on Wikipedia but without a dedicated company entity, so AI models can confuse it with similarly named subjects.
The homepage meta description reads "Startseite" (Meta description too short (1 words). No OG description (falling back to meta)) - this is the summary AI engines are most likely to quote.
Structured data on the homepage: canonical. Adding Organization and FAQ schema would further help AI crawlers parse the brand's identity.
AI-crawler access: robots.txt mentions GPTBot, ChatGPT-User, ClaudeBot, Google-Extended, PerplexityBot - all allowed - robots.txt controls whether engines like GPTBot and ClaudeBot can read the site at all.
Content is DE-only, limiting citation in English-language AI answers.
Detected tech stack: Apache.
Social footprint: verified profiles on LinkedIn, Facebook, Instagram, YouTube, GitHub; no detected presence on X (Twitter) - consistent profiles reinforce the brand's identity across the web.
0 Reddit mentions - community discussion signals real-world reputation to AI models.
Live results from asking a general-purpose AI assistant about the brand, checked October 2026.
When asked "What is Startseite?", Claude could not identify the brand as of October 2026. I don't recognize this specific company; "Startseite" just means "homepage" in German, and pei.de doesn't correspond to any organization I have reliable information about, likely because it's too small or niche to have a strong presence in my training data.
When asked "Best brands similar to Startseite?", Claude would not surface Startseite as of October 2026. I can't recommend a company I don't have verified information about.

Startseite scores 46/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
Startseite has a limited AI-visibility profile at 46/100 - a proxy for how readily ChatGPT, Perplexity and Google's AI Overviews can recognise and cite it. Its strongest area is recommendation likelihood (63/100) and its weakest is trust (34/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #64,165 (Tranco) and a Moz Domain Authority of 63/100. The main gaps holding it back: no clear Wikipedia entity to anchor it in LLM training data, thin schema.org structured data and no llms.txt to steer AI to its best pages. In a live check (October 2026), Claude could not identify Startseite from memory, confirming the gaps above.
The score combines seven dimensions - name quality, digital presence, visual identity, messaging clarity, trust foundation, AI discoverability, and brand authority - into a single objective benchmark.
Ranked closest to Startseite: Pearl Meyer (74/100), Pattern Brands (74/100), Penny Morrison (74/100), PeopleLooker (74/100).
