A text ad is a form of marketing communication that advertisers can use to promote their product or service on the client account.
Where text ads appear
These ads can appear on Google results pages and across the Google Network, which includes the Search Network, search partners and the Display Network. Text ads might look different on the Display Network, or on mobile.
Bear in mind that text ads often appear with language that labels them as advertisements so that viewers understand that the links are paid promotions.
