The first step is to set up a Google Ads account if you don't already have one. Once that's done, researching your competitors is as simple as searching their company name or website URL in the search bar at the top of the page. You will then see all the active campaigns they have running along with detailed information about each one including ad copy and performance metrics like cost per click (CPC). If there are multiple accounts associated with the same company (which is common), make sure to select “See all accounts” in order to get an accurate picture of their activity across accounts.
