GDN and Search Network are two Google Ads networks that help businesses reach customers.

• Search Network: Shows ads to users actively searching on Google using keywords.
• Google Display Network (GDN): Shows visual ads on websites, apps, and videos while users browse online.

In short:

• Search Network = Captures demand
• GDN = Creates awareness

Understanding their differences helps marketers choose the right advertising strategy.

What Is Google Display Network (GDN)?

The Google Display Network (GDN) is Google’s advertising network that allows businesses to show visual ads across millions of websites, mobile apps, YouTube, and other online platforms. Instead of targeting people who are actively searching, GDN reaches users while they are browsing content online.

These ads can appear in different formats, such as images, banners, videos, and interactive ads, helping businesses attract attention and increase brand visibility.

Types of GDN Ads

• Banner Ads.
• Image Ads.
• Responsive Display Ads.
• Rich Media Ads.
• App Ads.

Example

Suppose a student is reading an article on a news website. While browsing, they see a banner advertisement promoting a Digital Marketing Course. Even though the student was not searching for the course, the ad appears because the website is part of the Google Display Network.

Why GDN Matters

GDN helps businesses:

• Increase brand awareness.
• Reach large audiences.
• Build visibility.
• Support remarketing campaigns.
• Generate interest.

The main goal of GDN is to introduce brands, products, or services to potential customers and keep them engaged throughout their online journey.

What Is Google Search Network?

The Google Search Network is a group of search-related websites where advertisers can display text-based ads. These ads appear when users search for specific keywords on Google or its search partners.

Advertisers choose keywords related to their products or services, and Google shows their ads to users whose searches match those keywords.

Example

A user searches:

Best Digital Marketing Course

Google displays sponsored ads at the top of the search results page. These ads are part of the Google Search Network because they are triggered by the user’s search query.

Why Search Network Matters

Search ads help businesses:

• Reach interested users.
• Generate leads.
• Increase conversions.
• Drive website traffic.
• Capture buying intent.

The main goal of the Search Network is to connect businesses with users who are actively looking for information, products, or services, making it highly effective for generating leads and sales.

How GDN Works

The Google Display Network (GDN) helps advertisers show visual ads to people while they browse websites, watch videos, use mobile apps, or check online content. Instead of targeting users based on what they are searching for at that moment, GDN targets them based on their interests, online behavior, demographics, and previous interactions with a website.

For example, if someone frequently visits marketing blogs or has previously visited a digital marketing institute’s website, Google may show them relevant display ads across websites within the Display Network.

Process

1. The advertiser creates display ads using images, banners, or responsive ad formats.
2. The advertiser chooses targeting options such as interests, demographics, topics, placements, or remarketing audiences.
3. Google analyzes user behavior and identifies people who match the selected audience.
4. The ads are displayed on relevant websites, apps, YouTube, or other platforms within the Display Network.
5. Users see the ads while browsing content.
6. Interested users click the ad and visit the advertiser’s website or landing page.

Example

Suppose a student is reading a technology blog about artificial intelligence.

While browsing the article, the student sees a banner advertisement promoting a Digital Marketing Course.

Because the student has shown interest in online learning and marketing-related content, Google considers the ad relevant and displays it.

If the student clicks the banner, they are redirected to the institute’s website to learn more about the course.

How Search Network Works

The Google Search Network displays ads when users actively search for information, products, or services on Google. Advertisers select specific keywords related to their business, and Google shows their ads when users enter matching search queries.

Since users are already looking for something, Search Network ads often attract highly interested visitors who are more likely to take action.

Process

1. The advertiser researches and selects relevant keywords.
2. The advertiser creates search ads and sets bids for those keywords.
3. A user enters a search query on Google.
4. Google compares the search query with advertisers’ keywords.
5. Through the ad auction process, Google determines which ads should appear.
6. Relevant ads are displayed at the top or bottom of the search results page.
7. The user clicks the ad and visits the advertiser’s website.

Example

Search Query:

Digital Marketing Course Near Me

When a user searches for this phrase, Google identifies advertisers targeting similar keywords such as “digital marketing course,” “marketing training,” or “digital marketing classes.”

Google then displays relevant search ads from those advertisers. If the user finds an ad useful and clicks it, they are taken directly to the advertiser’s website or landing page.
