Analysing Instagram Ad Performance: Metrics and Insights for Success

Instagram has become one of the most popular platforms for advertisers to reach their target audience. With over one billion monthly active users, it offers a vast potential for businesses to promote their products or services. However, running successful Instagram ads goes beyond just creating visually appealing content. It requires a thorough analysis of metrics to measure performance and gather valuable insights. In this blog, we will explore the key metrics to track and analyse when measuring the success of your Instagram ads.

Why measuring Instagram ad performance is important

Before delving into the metrics, let’s understand why measuring Instagram ad performance is crucial. By measuring ad performance, you can:

  1. Gain insights into the effectiveness of your ad campaigns: Metrics will help you understand if your ads are reaching the right audience, driving engagement, and delivering results.
  2. Optimise your ad strategy: Analysis of metrics will enable you to identify what works and what doesn’t, allowing you to make adjustments and optimise your ads for better performance.
  3. Allocate your budget effectively: With metrics, you can identify which ads are providing the best return on investment (ROI) and allocate your budget accordingly.

Now, let’s explore the key metrics you should be tracking to measure Instagram ad performance.

1. Reach and Impressions

Reach refers to the number of unique users who have seen your ad, whereas impressions represent the total number of times your ad has been viewed. Monitoring reach and impressions will give you an understanding of how many people your ad is reaching and the potential exposure it is generating.

By comparing these metrics across different campaigns or ad sets, you can assess the effectiveness of your targeting strategies and ad placements and make adjustments as necessary. Check out our blog Instagram Ad Targeting: Reaching Your Ideal Audience for more tips.

2. Engagement Metrics

Engagement metrics are vital for determining how well your audience is engaging with your ads. The following metrics fall under this category:

  • Likes: The number of users who have liked your ad. Likes indicate that your content resonates with your target audience.
  • Comments: Comments show user engagement and provide opportunities for interaction and feedback.
  • Shares: Shares indicate that users find your content valuable enough to share with their followers, which can significantly expand your reach.

Monitoring these metrics will help you gauge the level of interest generated by your ads. However, if you have a high engagement rate but a low click through rate, you’ll need to take a look at the messaging or Call-to-action (CTA) on your ad to find out why people aren’t following through with your desired action(s).

3. Click-Through Rate (CTR)

Click-through rate measures the percentage of users who click on your ad after seeing it. A high CTR indicates that your ad is effectively capturing the attention of your audience. A low CTR may suggest that your ad’s message or visuals need improvement. By analysing CTR, you can optimise your ads to increase engagement.

4. Conversion Metrics

Conversions are actions that you want users to take after seeing your ad, such as making a purchase, signing up for a newsletter, or downloading an app. The following metrics can help you evaluate the effectiveness of your ads in driving conversions:

  • Website Clicks: This metric tracks the number of clicks that lead users to your website from your ad. It is especially valuable if your conversion goal is to drive traffic to your website.
  • App Instals: If you are advertising a mobile app, monitoring the number of app instals resulting from your ad campaign is essential.
  • Purchases: Tracking the number of purchases made as a result of your ad campaign provides valuable insights into the ROI of your ads.

By analysing conversion metrics, you can optimise your campaigns to drive higher conversion rates and increase your return on ad spend. Pay close attention to the number of clicks v the number of conversions. If you have a very high click rate but aren’t seeing a good amount of conversions then take a look at your website – how user friendly is it, does it have a low load time, is it optimised for mobile etc.

5. Cost per Result (CPR)

Cost per result is the average amount you are paying for each desired action or engagement. This metric allows you to evaluate the efficiency of your ad spend and compare different campaigns or ad sets. By keeping CPR low, you can ensure that your ad budget is used effectively. Generally speaking, when you first start an advertising campaign the CPR will be slightly higher and will decrease over time. This is because the AI and algorithms used by Meta need to learn about your audience so that it starts showing your ads to those who are more likely to convert.

6. Return on Ad Spend (ROAS)

Return on ad spend measures how much revenue is generated for every dollar spent on advertising. By understanding the revenue generated from your ad campaigns, you can determine the effectiveness of your advertising efforts.

It is crucial to calculate ROAS accurately by considering all associated costs, such as production, targeting, and ad spend. A higher ROAS suggests that your campaigns are generating a positive return on investment.


Measuring the performance of your Instagram ads is vital for achieving success in your advertising efforts. By tracking and analysing the key metrics discussed in this blog, you can gain valuable insights into the effectiveness of your ad campaigns, optimise your strategies, and allocate your budget more effectively. Remember that it is essential to regularly review and adjust your ad campaigns based on the metrics you track, as the Instagram platform and user behaviour are subject to change. By harnessing the power of analytics, you can make data-driven decisions to ensure the success of your Instagram ad campaigns.
