In the digital marketing world, understanding the performance of your online ads is crucial for making informed decisions and optimizing your ad campaigns. One important metric is the conversion rate, which measures the percentage of users who complete a desired action, such as making a purchase or filling out a form, after clicking on an ad.

If you store your ad data in a SQL database, you can easily calculate the average conversion rate using the AVG function. Let’s see how.

Step 1: Retrieve Clicks and Conversions

The first step is to retrieve the number of clicks and conversions from your ad tracking table. Suppose you have a table called ad_performance with the following structure:

CREATE TABLE ad_performance (
  ad_id INT,
  clicks INT,
  conversions INT
);

You can use the following SQL query to get the total clicks and conversions for each ad:

SELECT ad_id, SUM(clicks) AS total_clicks, SUM(conversions) AS total_conversions
FROM ad_performance
GROUP BY ad_id;

Step 2: Calculate Average Conversion Rate

With the total clicks and conversions per ad, you can now calculate the average conversion rate using the AVG function. The conversion rate is calculated by dividing the total conversions by the total clicks and multiplying by 100 to get a percentage value.

SELECT ad_id, total_clicks, total_conversions, (total_conversions / total_clicks) * 100 AS conversion_rate
FROM (
  SELECT ad_id, SUM(clicks) AS total_clicks, SUM(conversions) AS total_conversions
  FROM ad_performance
  GROUP BY ad_id
) AS ad_summary;

Step 3: Interpret the Results

The final query will give you the average conversion rate for each ad. You can then analyze the results to identify the best-performing ads and make data-driven decisions to optimize your ad campaigns. Keep in mind that a higher conversion rate indicates better ad performance.

By regularly monitoring and calculating the average conversion rate, you can track the effectiveness of your online ads and make necessary adjustments to improve your campaign’s return on investment.
