Creating Ads with Dynamic Content Using a JSON file/Media Feed
ResponsiveAds supports JSON/Media feeds to power creative variants with dynamic content. Instead of manually editing every version of your creative, you can connect a Google Sheet or JSON file and have images, text, and links automatically populate your ad.
This is especially useful for ads like image carousels, product showcases, or rotating offers, where content changes frequently or at scale.
Why Use Feeds?
Dynamic updates – edit content in a Google Sheet and it flows into the creative.
Scalability – manage many products, listings, or variations from a single feed.
Consistency – use the same feed across multiple ads or campaigns.
Efficiency – no need to re-edit or rebuild creatives for every content change.
Example: Dynamic Image Carousel
A Dynamic Logo/Image Carousel can be powered entirely by a Google Sheet feed. Each row in the sheet represents a slide and may include:
Image (recommended: 3414 × 1920, URL from Media Gallery or external host)
Title (≤ 40 characters)
Price or details (optional)
CTA text (≤ 15 characters)
Click-through URL
Global Hotspot URL (optional)
Other assets you may include in your creative:
Brand logos (1000px long edge, PNG; vertical + horizontal)
Brand panel color (Hex/RGB)
Background color (Hex/RGB)
Setting Up the Google Sheet
Make a copy of the example sheet Use the provided Dynamic Carousel Example Sheet.
Fill in your content
Column A – ID or index number
Column B – Title (e.g., product name, address)
Column C – Image URL (e.g., from Media Gallery)
Column D – CTA Button URL
Column E – Global Hotspot URL
