Do banner ads need buttons?
Use buttons appropriately
Depending on the type of banner, buttons will often increase the click-through rate (CTR) of your ad. If you're going to use them, place them after your copy on the lower right side in (tastefully) contrasting colors. Always keep them consistent throughout the set of ads.
What is a clickable banner?
Inserting a link to your graphically designed banner, recipients are motivated to click on it and go to the landing page which has detailed information about what your business's new service offers. This in turn excels your brand awareness.
Where do you put the CTA in the banner?
The CTA should be placed after a statement that indicates what the readers will get. For instance, after reading a website banner or an ad, there's a CTA button that will lead viewers to 'learn more', 'buy now', etc. By doing so, brands can generate more leads or bump up conversion rates!
