Talkbotics has been running a campaign for their phone accessories and found it to be under-spending. Which of the following is a suggested approach to optimize the campaign?

The correct answer is "all of these" because each option addresses a common reason for under-spending in a sponsored ads campaign and offers a valid optimization strategy. Increasing visibility by adding ASINs expands the product catalog being advertised, potentially reaching more shoppers. Similarly, adding more keywords broadens the search terms that can trigger your ads, capturing a wider audience. Finally, increasing bids on high-performing keywords ensures your ads are more competitive and shown more frequently for searches that are already proven to convert, maximizing the impact of your budget. Individually, each of these actions can improve campaign performance; together, they offer a comprehensive approach to optimize an under-spending campaign.
