A banner is a graphical display that stretches over the top, bottom, or side of a WordPress website page. It often includes a brand name and logo, along with other visual elements, to promote a specific product, service, or event.
For example, if an online store has just announced a sale, then it can show a banner at the top of its website pages to inform new visitors about the promotion and encourage them to make a purchase.
A well-designed banner can make a strong impression and invite visitors to explore the rest of your site.
Plus, banners can also be used to promote affiliate products, increase brand awareness, build an email list by encouraging visitors to sign up for your newsletter, and drive traffic to other pages on your site.
