One great way to introduce potential clients to your products or services is through search engine campaigns. You'll only pay for these advertisements if and when they're interacted with, so setting a clear objective (such as more clicks to your site, more purchases, or more leads) is essential (PPC - Pay per click).
Showcase your wares on the largest online marketplace with the help of your shopping ads. You will only be charged if a potential customer actually visits your website or views your local inventory.
Advertise on Google's news pages, blogs, and other Google properties like Gmail and YouTube via a display campaign.
Get in front of your target audience on YouTube with a video marketing campaign. Only when a user engages with one of your ads (by clicking a CTA, a card, or a complementary banner, for example) will you be charged.
