If you have competition bidding on your brands, you can choose to simply respond with brute force dollar for dollar bidding wars and play their same game and spend boat loads of cash to steal back your own traffic.  Or you be more strategic and be more efficient with your money.  To begin with, you should have your brand protection campaign as its own unique campaign within your Google Ads account so that you have the ability to monitor and manage it properly, separate from your other campaigns.

Now let's understand the difference in how people access search results and why that should matter to you. Since about mid 2016, more than half of the Internet traffic, both search and browsing, has been happening on mobile phones.  That means over half of your potential clients are viewing the web, including search results, with Google Ads, with the small screen in the palm of their hand.  Research by Google has show that mobile users are nearly twice as likely to click ads shown at the top of the search results page than to scroll down to where the organic listings are found.  Quite often a Google search result on a mobile phone will display two or three ads, perhaps a Google maps section, a knowledge panel, then the organic results.  That requires scrolling 3 or 4 screens worth to get to the organic listings.  Contrast that with what is immediately viewable on a desktop search.  Desktop users will often see the ads, map results, knowledge panel, and three or four organic listings all on the first screen full of search results.  While desktop users will more often click one of the organic listings, mobile users will tend to click an ad.  You should get most of the desktop clicks to your site for branded search from organic listings as desktop users will be able to see you in search results and gravitate towards non-ad clicks.
