Comprehensive guide to identifying and correcting misinformation about your brand in Claude.

Claude is telling users you're based in San Francisco when you're in Austin. It's describing your product as a B2C tool when you're B2B-only. And unlike other AI models, Claude often cites its sources, making these errors look authoritative. The misinformation spreads because users trust what appears to be well-researched answers. Here's how to fix what Claude gets wrong about your brand.

## The Problem

Claude's knowledge comes from training data with a cutoff date, plus real-time web searches when users enable that feature. This creates two problems: outdated information in its training, and misinterpretation of current web sources. When Claude finds conflicting information, it sometimes blends facts from different time periods or sources.

## The Solution

You can't edit Claude's training data, but you can control what it finds when it searches. Claude heavily weighs authoritative sources and recent, well-structured content. By systematically cleaning up your web presence and addressing the specific sources Claude relies on, you can dramatically improve accuracy within weeks.

## Test Claude's current knowledge about your brand

Ask Claude specific questions: company founding date, headquarters location, pricing, key products, leadership team. Test both with and without Claude's web search enabled. Document every error with screenshots. You'll see patterns in where Claude gets confused.

## Identify Claude's preferred sources

When Claude cites sources, note which sites it references most. Check if those sources have outdated or incorrect information about your brand. Claude particularly trusts news sites, Wikipedia, Crunchbase, and official company pages. These become your priority targets for corrections.

## Clean up your official web presence

Update your About page, press kit, and executive bios with current, explicit facts. Use clear headings and bullet points. Add schema markup for key data points like founding date and headquarters. Claude parses structured information better than prose.

## Fix high-authority third-party sources

Update your Crunchbase profile, Wikipedia page (if you have one), and LinkedIn company page. Reach out to news outlets with correction requests for outdated articles. Focus on sites with high domain authority that Claude frequently cites.

## Publish correction-focused content

Write blog posts or press releases that directly address common misconceptions. Use headers like 'Is [Brand] owned by [Wrong Company]?' followed by clear corrections. This gives Claude unambiguous signals about what's accurate.

## Monitor with targeted searches

Test the same questions weekly. Claude's web search results can change frequently as it discovers updated content. Track which corrections take hold and which need more reinforcement. Keep a log of Claude's responses over time.
