The three common formats of native advertising are In-Feed, In-Article, and Recommendation Widgets. In-Feed ads are the most common type of native ad and are often seen on social media sites like Facebook and Twitter. These ads are integrated into the feed of content and are meant to blend in with the surrounding content. In-Article ads are less common, but can be seen on sites that have a lot of text content, like news sites. These ads are inserted into the middle of an article and are usually labeled as “sponsored content” or something similar. Recommendation Widgets are the least common type of native ad, but can be seen on sites that have a lot of user-generated content, like YouTube. These widgets show recommended content to users based on their activity on the site.
