To monitor and report on ad performance, you can follow these steps:

1. Set up Conversion Tracking: Use HTML tags to track conversions on your website. Place the conversion tracking tag on the page that users see after completing a desired action, such as making a purchase or submitting a lead form. For example, you can use the following HTML code to track a purchase conversion:

<script>
  gtag('event', 'conversion', {
    'send_to': 'AW-XXXXXXX/XXXXXXXX',
    'value': 1.0,
    'currency': 'USD'
  });
</script>

Replace AW-XXXXXXX/XXXXXXXX with your Google Ads conversion ID.

2. Use UTM Parameters: Add UTM parameters to your ad URLs to track the source, medium, and campaign name. For example, if you're running a Facebook ad campaign, you can add the following parameters to your ad URL:

<a href="https://example.com/?utm_source=facebook&utm_medium=cpc&utm_campaign=summer_sale">Click here</a>

Replace https://example.com/ with your landing page URL.

3. Set up Google Analytics: Implement Google Analytics on your website using the HTML tracking code provided by Google. This will allow you to track various metrics related to your ad performance. For example, you can use the following HTML code to include the Google Analytics tracking code:

<script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXXXX-X"></script><script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());
  gtag('config', 'UA-XXXXXXXX-X');
</script>

Replace UA-XXXXXXXX-X with your Google Analytics tracking ID.

4. Use Ad Platforms' Reporting Tools: Most ad platforms provide built-in reporting tools that allow you to monitor ad performance. For example, Google Ads provides a comprehensive dashboard where you can view metrics like impressions, clicks, conversions, and cost-per-click (CPC).

5. Create Custom Reports: If the built-in reporting tools don't provide the specific data you need, you can create custom reports using tools like Google Data Studio. HTML tags can be used to embed these reports on a webpage or share them with stakeholders.

Remember, monitoring and reporting on ad performance is an ongoing process. Regularly analyze the data and make adjustments to optimize your campaigns for better results.
