This is totally wild. Google is now showing you what it considers to be your brand. Go to Google Search Console, click the search results performance report, add filter query, choose this new option for branded queries.
Now you're gonna get a list of all of these terms that Google thinks represent your brand.
There'll be things like misspellings, products and services that Google's associating with your brand, potentially competitors. And once you know what people are searching for, you can actually use this to optimize. You can improve your website to target these specific terms, and that'll actually help you get more traffic for these branded terms.
And if you want to see exactly how you rank across your whole city for a loss of these terms, there's no better tool on the market than White Sparks Local Ranking Grills.
