What is conversion tracking?

Conversion tracking is the process of measuring and recording valuable actions users take after interacting with an advertisement, website, or marketing campaign. These actions, known as conversions, can include purchases, lead form submissions, phone calls, newsletter sign-ups, or bookings.

Conversion tracking helps businesses understand whether their advertising campaigns are achieving their objectives and how effectively their marketing budgets are being used.

Key features of conversion tracking

• Measures user actions: Records when visitors complete predefined goals, such as purchasing a product or submitting a form.

• Tracks campaign performance: Helps identify which advertisements, campaigns, and channels are associated with conversions.

• Supports automated bidding: Platforms such as Google Ads can use eligible conversion data to optimize strategies such as Maximize Conversions and Target CPA.

• Measures advertising costs: Helps calculate metrics such as cost per conversion (CPA).

• Tracks conversion value: Records revenue or assigned values to help businesses evaluate return on ad spend (ROAS).

• Supports optimization: Helps marketers improve targeting, creative content, landing pages, and budget allocation.

Example of conversion tracking

A Shopify jewellery store runs a Google Ads campaign promoting diamond rings.

Suppose the campaign generates:

• Ad spend: ₹10,000

• Ad clicks: 500

• Completed purchases: 25

• Tracked purchase revenue: ₹50,000

Conversion tracking records the 25 purchases and their associated values, subject to the store’s tracking setup and attribution rules.

The campaign’s cost per purchase is:

Its return on ad spend is:

That is a 5× ROAS, or ₹5 in tracked revenue for every ₹1 spent on advertising.
