Great question! You're right to ask about the brand name versus other assets-definitely start by grabbing the brand guidelines if they exist.
For manual checks, here's what's worked for me:
🔍 Pop into GA4 and look at geographic anomalies. If you're seeing visits from a region that doesn't match your sales or engagement, that's a red flag worth investigating.
📋 Build out a keyword list-both direct and indirect-based on intent and relevance. The other party is likely using your name to imply trust, authority, or a sale. Search those terms manually and see what pops up. If you get a hit, track down the company name or website, then run it through Google Ads Transparency Center.
🌐 Another handy trick: search domain registrations related to your brand. Head to Google Ads Transparency Center, enter your advertiser/brand name, and see which domains surface.
📱 For other platforms it's trickier, but the same keyword approach is a good starting point. Meta has its own transparency centre too.
📊 Keep everything tidy in a spreadsheet. Once you've got the company name and solid confirmation, compile the evidence and hand it off to legal.
