Here are some definitions:
- according to Wikipedia:
"In the Internet, a banner is a graphic form for providing information or advertising content, often a link to a page of a promoted product."
And another example:
Banner ads are based on images, not text, and are a popular form of on-site advertising. The purpose of banner advertising is to promote the brand and / or entice website visitors to visit the advertiser's website.
In summary, all banner ads have the same basic function: click on the image / media object you see on the website and your web browser will take you to the advertiser's website / landing page. These are simple but very important HTML snippets, and their online presence can make a big difference to online businesses and brands.
So how exactly do they work?

When creating a banner ad, you usually have one goal:
Banner ads (campaigns in Google Ads) are designed to drive traffic to your website by linking to it.
