# 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

1. **Make a copy of the example sheet**\
   Use the provided [Dynamic Carousel Example Sheet](https://docs.google.com/spreadsheets/d/1Nhgthc_2jFnFGA4C__Jx8egT5L49hKjQrGeEm6QP9Bo/).
2. **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
3. **Publish the sheet**
   * Go to **File → Publish to the web**
   * Leave the default settings and click **Publish**
   * Copy the **Google Sheet ID** (the string of characters between `/d/` and `/edit` in the URL).

***

### Creating a Feed in Media Gallery

1. Open the **Media Gallery** → **Feeds** tab.
2. Click **Add a New Feed**.
3. Enter a name for your feed.
4. Set **Parser Type** to **Transform Google Sheet to JSON**.
5. Paste the Google Sheet ID into the field.
6. Choose an update interval (e.g., 1 hour).
7. Save, then run **Options → Force Update** to generate the JSON feed.
8. Copy the feed URL.

***

### Connecting the Feed to Your Creative

1. Open your creative in the editor.
2. Select the **Custom Code Editor**.
3. Replace the default feed URL in the JavaScript with your new feed URL.
4. Save the creative.

Now your ad will automatically pull content from the feed.

***

### Updating the Content

* Edit rows in your Google Sheet to add, remove, or update items.
* In **Media Gallery → Feeds**, use **Force Update** to sync immediately.
* Refresh the JSON link to verify updates.
* Ads connected to the feed will reflect changes automatically.

ℹ️ Feeds also update every **12 hours** by default.

***

### Styling and Customization

* **Logos**: Replace brand logos by selecting the **Brand Logo** element in the editor and uploading your file.
* **Click-throughs**: Update per-slide CTAs in the sheet, or apply a global click-through at the **Deployment** level.
* **Colors**: Change background, brand panel, or CTA button colors in the right-hand panel, then copy style settings across sizes.
* **Consistency across sizes**: Use **Copy element settings** → *Other style properties* to apply font, spacing, and color changes across all formats.

***

### QA and Preview

1. Save your creative.
2. From the **Summary Page**, click **Preview**.
3. Check the **Responsive view** by resizing your browser window.
4. Switch to the **Breakout view** to confirm each format size.
5. Verify there are no overlaps, missing assets, or broken links.

***

### Deploying the Creative

2. Click **Publish** to generate an ad tag.
3. Select your preferred serving platform.
4. Copy the ad tag to your clipboard and save it for trafficking.
