What Is Conversion Tracking?

Conversion Tracking is a Google Ads feature that helps advertisers measure the actions users take after clicking on or interacting with an advertisement. These actions are known as conversions because they represent users completing a desired goal.

A conversion can be any valuable activity that contributes to business success, such as making a purchase, filling out a contact form, signing up for a newsletter, downloading an app, or calling a business.

Common Conversion Actions

• Product purchases.
• Lead form submissions.
• Course enrollments.
• Phone calls.
• Newsletter signups.
• App installs.

By tracking these actions, advertisers can understand whether their advertising campaigns are producing meaningful results and generating a return on investment.

Example

A user clicks an ad for:

Digital Marketing Course

Then completes:

Course Enrollment

Google records this action as a conversion because the user completed the desired goal after interacting with the advertisement.

Why Conversion Tracking Matters

It helps advertisers:

• Measure ROI (Return on Investment).
• Track sales and revenue.
• Analyze lead generation performance.
• Optimize campaigns based on results.
• Improve overall advertising effectiveness.

Without conversion tracking, advertisers may know how many people clicked their ads, but they would not know whether those clicks resulted in valuable business outcomes. The main goal of conversion tracking is to measure results and evaluate campaign success.

What Is a Remarketing Tag?

A Remarketing Tag is a small piece of tracking code placed on a website to collect information about visitors. Its primary purpose is to build audience lists that advertisers can use for remarketing campaigns.

Unlike conversion tracking, a remarketing tag does not focus on measuring completed actions. Instead, it records visits and user behavior so advertisers can reconnect with those visitors later through targeted advertisements.

How It Works

When someone visits a website, the remarketing tag adds that visitor to a specific audience list. Advertisers can then create campaigns that show ads specifically to people who have already visited their website.

Example

A user visits:

Digital Marketing Course Page

but leaves without enrolling.

The Remarketing Tag records that visit and adds the user to a remarketing audience.

Later, the user may see:

Enroll in Our Digital Marketing Course

ads across Google platforms such as YouTube, Google Display Network websites, or Google Search.

Why Remarketing Tags Matter

They help advertisers:

• Re-engage previous visitors.
• Build custom audience lists.
• Increase conversion opportunities.
• Improve brand recall and awareness.
• Recover potential customers who left without converting.

Many users do not take action during their first visit to a website. Remarketing allows businesses to stay visible and encourage those users to return and complete a purchase, signup, or other desired action. The main goal of a remarketing tag is audience creation and visitor re-engagement.

How Conversion Tracking Works

Conversion Tracking works by placing a tracking code on a website or landing page. When a user clicks on an advertisement and completes a specific action, Google Ads records that action as a conversion.

Step-by-Step Process

1. A user sees and clicks your Google Ad.
2. The user visits your website or landing page.
3. The user performs a valuable action, such as making a purchase, filling out a form, or signing up for a course.
4. The conversion tracking tag detects the completed action.
5. Google Ads records the conversion and displays the data in campaign reports.

Example

Suppose a digital marketing institute runs an ad promoting its course.

User clicks:

Digital Marketing Course Advertisement

After visiting the website, the user completes:

Course Registration Form

The conversion tracking code records the action, and Google Ads reports:

1 Conversion

This helps the advertiser understand that the ad successfully generated a lead or sale.

How Remarketing Tags Work

Remarketing Tags work by collecting information about visitors who interact with your website. Instead of tracking completed conversions, they identify users and place them into audience lists that can be targeted with future advertisements.

Step-by-Step Process

1. A user visits your website.
2. The Remarketing Tag loads automatically in the background.
3. Google adds the visitor to a specific audience list based on their behavior.
4. The advertiser creates a remarketing campaign targeting that audience.
5. The user sees relevant ads while browsing other websites, YouTube, or Google platforms.

Example

A user visits:

SEO Course Page

The user reads the information but leaves without enrolling.

The Remarketing Tag adds the visitor to:

SEO Course Visitors Audience

Later, when the same user browses other websites or watches videos on YouTube, they may see ads such as:

This gives the business another opportunity to bring the visitor back and increase the chances of conversion.
