Live results from asking a general-purpose AI assistant about the brand, checked September 2026.
When asked "What is Startseite?", Claude could not identify the brand as of September 2026. I don't recognize this specific company; "Startseite" is simply the German word for "homepage," and rosenberg-gmbh.com appears to be a small or regional German business without enough presence in my training data to identify what it actually does.
When asked "Best brands similar to Startseite?", Claude would not surface Startseite as of September 2026. I can't recommend a company I can't verify or describe accurately.

Startseite scores 32/100 for AI visibility - how well ChatGPT, Claude, Perplexity and Google AI Overviews can discover, identify and cite the brand.
Startseite 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 (48/100) and its weakest is visibility (17/100). It benefits from a Wikidata knowledge-graph entry, a global traffic rank of #3,418,700 (Tranco) 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 33/100 and no llms.txt to steer AI to its best pages. In a live check (September 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.
