Diagnosis Steps
1. Check Mute Settings:
- Ensure that the microphone and speakers are not muted in both the conferencing application and system settings.
- Look for mute/unmute buttons in the meeting interface.
2. Verify Audio Device Selection:
- Open the conferencing application’s audio settings.
- Ensure the correct microphone and speaker are selected.
- Test the selected devices within the application.
3. Inspect Physical Connections:
- Ensure microphones and speakers/headphones are properly plugged in.
- Check for loose or damaged cables.
- If using Bluetooth devices, confirm they are connected and paired correctly.
4. Restart Audio Services:
- Restart the computer to refresh the audio services.
- If using Windows, restart the “Windows Audio” service from the Services application.
5. Check for Software Conflicts:
- Close other applications that may be using the microphone, such as recording software or VoIP applications.
- Disable unnecessary startup applications that may interfere with audio.
6. Update Audio Drivers:
- Open Device Manager (Windows) or System Preferences (Mac) and update the audio drivers.
- Download and install the latest drivers from the manufacturer’s website.
7. Grant Necessary Permissions:
- Check system privacy settings to ensure the conferencing app has permission to use the microphone.
- For Windows: Go to Settings > Privacy & security > Microphone and ensure the app has access.
- For Mac: Go to System Settings > Privacy & Security > Microphone.
8. Test with Another Application:
- Try using the microphone and speakers with another application (e.g., voice recorder, another conferencing app).
- If the issue persists, it may be a system-wide problem.
9. Check Internet Connection:
- Run a speed test to ensure adequate bandwidth.
- Switch to a wired connection if possible.
- Restart the router/modem.
Potential Solutions
- Unmute Audio: Ensure the microphone and speaker is unmuted.
- Select Correct Audio Device: Choose the correct microphone and speaker in settings.
- Reconnect or Replace Hardware: If a device is faulty, replace it with a working one.

Question 3
Review the document available at https://developers.citrusad.com/integration/docs/product-ad, and provide suggestions for enhancing the quality and readability of the documentation.
Here are some improvements I suggest for clarity, consistency, and readability:
General Improvements I made based on:
1. Conciseness & Readability – Some sections are wordy. Simplifying sentences and breaking down long paragraphs would improve readability.
2. Consistency – Standardize terms like “campaign settings,” “ad strategy,” and “placements” to ensure uniformity throughout the document.
3. Formatting & Structure – Use bullet points for lists where applicable. Add bold headings and subheadings to improve navigation.
4. Grammar & Spelling – Minor grammatical tweaks for better flow.

Product Ad Campaigns for Retailers
This section guides retailers through creating a product ad campaign. Product ads help put your products at the forefront of the retailer’s website. Once your campaign is live, you can track key metrics in the portal and optimize it accordingly.
What Are Product Ads?
Also known as sponsored products, product ads enhance discoverability and boost sales at the digital point of purchase. They help advertisers secure premium positions, ensuring their products are showcased effectively.
Retailers typically integrate Epsilon Retail Media’s product ads within organic listings before displaying them to customers. We also provide fixed tenancy campaigns, allowing retailers to reserve exclusive ad placements for a single brand over a set period.
For supplier teams creating campaigns independently, it is recommended to use the auction flow for campaign setup.
Prerequisites
Before creating a campaign, ensure your product catalog is synced with at least one product. For details, see Product Catalog.
Step 1: Select Your Team
1. Access your sandbox account or campaign platform (e.g., sandbox.citrusad.com).
2. Navigate to Campaigns and click New Campaign.
3. In the Team section, search for your retailer team and click Next.
�� Teams are created by your supplier.
Step 2: Define Campaign Settings
1. Select Campaign Type
- Choose Product Ad as the campaign type.
2. Choose Ad Placement
Placements determine where ads appear and impact campaign success. Available placement types include:
- Category
- Category Cross-Sell
- Search Cross-Sell
- Broad Display (Home)
- PDP (Product Detail Page)
- Search
�� For detailed descriptions, see Placements.
3. Name Your Campaign
- Choose a name that makes identification easy (e.g., Cadbury Chocolate June Clearance). The name appears in Campaign Manager and Reports.
4. Select Campaign Duration
- Define the start and end dates – Campaign will start at 12:01 AM on the start date and will end at 11:59 PM on the end date.
- Always On – Starts immediately and runs continuously based on the selected strategy.
5. Choose a Wallet
- Your wallet funds the campaign. If only one wallet is available, it is selected automatically.
- To add another wallet, contact your Technical Account Manager.
6. Add Product Catalogs
- If multiple catalogs are available, select up to six catalogs and click Add.
- If only one catalog is available, select and add it.
- Use the search function to find specific catalogs.
- Once selected, catalogs appear in the Catalogs Selected table.
Click next to proceed.
Step 3: Select Products for Advertisement
Search for products by name, barcode number, or relevant keywords (e.g., brand name). You can add single or multiple products.
�� Notes:
- Two characters must be entered to trigger search results.
- Some product selection restrictions may apply. See Product Selection Restrictions for details.
- Out-of-stock products will not be served as ads.
- If multiple catalogs were selected in Step 2, each catalog must contain at least one product.
Adding Products via CSV Upload
- To add product details, click the Upload button and select the CSV file.
- The CSV file may contain product codes or product code + catalog ID pairs.
- Click Download template to get a sample CSV format.
- After upload, review stock status and click Import.
Product Stock Indicator
Stock status is color-coded:
- Green – Available in all selected catalogs.
- Amber – Available in some, but not all, selected catalogs.
- Red – Out of stock in all selected catalogs.
Click Next to proceed.
�� If you’re not ready to select products, click ‘Skip this stage.’ The campaign will be saved as a draft.
Step 4: Configure Targeting Criteria
Targeting criteria define the audience for your campaign. This can include:
- Demographics (age, gender, location, income level)
- Past purchasing behavior
- Interests
�� Broad Display placements do not support targeting criteria.
Category Targeting

Click Next after finalizing search terms.
Step 5: Define Ad Strategy
�� For supplier teams, it is recommended to use the auction flow.
Fixed Tenancy Ads (FTA)
- FTA campaigns secure a fixed ad placement for a predetermined time and cost.
- FTA takes precedence over auction campaigns in overlapping placements.
Steps to Define Spend Strategy
1. The selected wallet from Step 2 is used by default. Click Change to switch wallets.
2. To ensure the campaign doesn’t exceed a certain amount, set a spend limit.
3. Select Fixed Position – The system verifies placement availability.
4. Specify campaign cost – The amount agreed upon between supplier and retailer.
5. (If applicable) Allocate spend across multiple catalogs for reporting.
Click Next to proceed.
Step 6: Review & Submit for Approval
