What is Remarketing?
Remarketing (also called retargeting) is the strategy of reaching website visitors who did not convert again across multiple channels. A prospect downloads a whitepaper but does not register for the webinar. With remarketing you show this person your webinar ad while they browse the web.
The principle is simple: the first exposure does not always lead to a conversion. Multiple exposures across different channels (display ads, YouTube, Gmail) increase the probability that the person eventually converts.
Remarketing in B2B Context
In B2B, long sales cycles are the norm. A prospect could visit a website today, read a blog post tomorrow, watch a webinar in a week, and book a demo in 4 weeks. Remarketing is essential to reach this person throughout the entire process.
Statistics show that 98% of website visitors do not convert on their first visit. With remarketing you can reach that 98%. This is enormous potential: if your normal website conversion rate is 2%, you can convert another 3-5% with remarketing from people who have already visited the website.
For B2B, remarketing is often more cost-effective than acquiring new traffic. A remarketing click often costs 30-50% less than a normal display ad click, because it is a "warm" lead.
How Remarketing Works
Remarketing is based on cookies and tags:
- Tracking pixel installation: you place a Google remarketing tag on your website (via Google Tag Manager)
- User identification: when someone visits your website, Google sets a cookie in their browser
- Audience creation: Google builds a "remarketing audience" from people who visited your website
- Ad delivery: you create remarketing campaigns and show ads to this audience across display ads, YouTube, Gmail, etc.
- Cookie tracking: for up to 180 days after the first website visit, these users can be reached with ads
The process is fully GDPR-compliant if you correctly obtain consent for tracking.
Types of Remarketing
| Remarketing type | How it works | Best for |
|---|---|---|
| Standard remarketing | Pixel-based, all website visitors | Broad awareness, high reach |
| Dynamic remarketing | Shows products/pages that were visited | E-commerce (less relevant for B2B) |
| List-based remarketing | Based on customer lists (email) | CRM integration, highly qualified |
| Video remarketing | Video ads on YouTube | High engagement, long messages |
Best Practices for B2B Remarketing
- Segment your audiences: not all website visitors are the same. Create separate remarketing audiences:
- whitepaper downloader (mid-funnel)
- Blog visitors (top-funnel)
- Pricing page visitors (bottom-funnel, hot lead)
- Demo requests (almost closing)
- Customized messages: the remarketing ad should be based on previous behavior:
- Whitepaper downloader sees: "see the case study that follows the whitepaper"
- Pricing page visitor sees: "free for 30 days"
- Demo request sees: "your appointment coming soon"
- Frequency capping: do not show the same ad 20x per day. That is aggressive and counterproductive. Maximum 5-8 impressions per user per day.
- Timing is important: show remarketing ads shortly after the website visit. In the first week, conversion rates are highest. After 30 days, probability drops dramatically.
- Use video remarketing: a 30-second video demo on YouTube is more effective than a static banner. engagement is higher.
- Integrate with CRM: if possible, synchronize your CRM data with Google ads. People who have already booked a demo should NOT see the "book demo" ad anymore.
- Negative audiences: create audiences of people you do NOT want to show ads to (e.g., existing customers). This saves budget.
Remarketing with Email Lists (Customer Match)
This is an advanced form of remarketing. You upload a list of email addresses (e.g., from your CRM or newsletter), and Google tries to match these email addresses to their Google accounts. Then you show ads to these specific people.
Advantages:
- Extremely highly qualified (these are your customers or leads)
- Private and secure (no pixel tracking, only hashes)
- Excellent for GDPR compliance
- match rate typically 50-70% (Google can match 50-70% of emails to their accounts)
Ideally combined with remarketing segmentation: newsletter subscribers see different ads than CRM contacts.
Remarketing Frequency and Burnout
A classic problem: "I see your ad everywhere!" The user feels stalked and has negative feelings about your brand. This is called "ad fatigue".
To avoid:
- Maximum 5-8 impressions per user per 24 hours
- Maximum 30 impressions per user total
- After 180 days (Google standard) the cookie is deleted anyway
- Change creative regularly (new images, new copy) instead of showing the same ad
- Use "frequency capping" settings in Google ads
ROI Example: Remarketing Impact
A B2B company has these metrics:
- website visits per month: 10,000
- website conversion rate: 2% (200 conversions)
- average cost per click: EUR 5
- ad budget monthly: EUR 10,000
After implementing remarketing:
- additional conversions from remarketing: 80-120 (from the 9,800 non-converters)
- average remarketing CPC: EUR 2.50 (50% cheaper, because warm)
- additional monthly spend for remarketing: EUR 3,000
- additional monthly conversions: 100
- additional cost per conversion: EUR 30
- total cost per conversion (with remarketing): drops from EUR 50 to EUR 35
With remarketing: +100 conversions per month, but EUR 15 cheaper per conversion. That is the power of remarketing in B2B.
Remarketing and Attribution
Remarketing is hard to attribute. A user sees three touchpoints: search ad, display ad, remarketing ad. Who gets credit?
Google ads standard is "last click" attribution. This means the last click (often remarketing) gets credit. This makes remarketing look "cheaper" than it is.
For better insights use Google analytics or Google Tag Manager to understand multi-touch attribution.
Remarketing and Data Protection (GDPR)
Remarketing is GDPR-compliant if:
- You obtain explicit consent for the tracking pixel
- You explain remarketing in your privacy policy
- You offer an opt-out mechanism (e.g., Google's ads preferences)
- You correctly configure Google Tag Manager with consent management
For B2B in Europe, remarketing is safe to use with these guidelines.
Remarketing in Performance Max and Automated Campaigns
Performance max campaigns automatically use remarketing as one of the targeting methods. This is more efficient than manual remarketing campaigns for many advertisers.
The future is moving toward automated, machine learning-driven remarketing, not manual campaigns.
Conclusion: Remarketing is Essential for B2B
Remarketing is often the highest ROI channel in B2B Google ads strategies. With the same budget as new user acquisition you often get 2-3x as many conversions from remarketing.
B2B companies without systematic remarketing are leaving 30-50% of potential conversions on the table. Implement remarketing today, and you will see immediate impact on your lead generation ROI.
