A web ad is an online advertisement, typically in the form of a banner or rectangle, that appears on web pages. Ads can also be delivered via email or text message, or even on social media platforms like Facebook and Twitter. Web ads are designed to catch your attention and lead you to click through to the advertiser’s site to learn more or buy a product or service. The advertiser pays the publisher for each click.

The size of an ad should be large enough to grab the attention of users, but small enough to keep the page loading speed fast. And for this, your web ads size and dimension should be in an optimized way, and for this, just follow Appy Pie’s recommended standard web ad size chart.
