You can use the brand name of SEMrush and BeRush as a keyword in your PPC campaign.

It is false that you can use "SEMrush" and "BeRush" as keywords in your PPC campaign. This is because these are trademarked brand names. Most advertising platforms, like Google Ads, have policies against trademark infringement. Using a competitor's trademarked brand name as a keyword in your PPC campaigns is generally prohibited unless you are an authorized reseller or partner. Doing so could lead to your ads being disapproved or your account being suspended. Instead, focus on keywords relevant to your own brand, products, or services.
