RLSA

RLSA is a Google Ads technology that allows advertisers to show search ads to users who have previously interacted with their website. RLSA combines remarketing with search advertising to make ads more precise and improve conversions.

What is RLSA?

RLSA is a remarketing list used specifically in search campaigns. When a person enters a query into Google and is also on a remarketing list, the advertiser can:

• Adjust bids,
• Show different ads,
• Show ads exclusively to that segment,
• Expand keyword targeting specifically for that audience.

Example:
A user viewed a laptop on a website but didn’t purchase it. The next time they search for “buy a laptop,” they see a personalized ad.

How RLSA Works

1. A remarketing tag or Google Analytics tracking is installed on the website.
2. Users are added to lists based on their behavior (e.g., viewed cart, visited specific pages).
3. These lists are linked to search campaigns.
4. When a user enters a search query, the system checks if they are on a list.
5. If they are, they see special ads or experience adjusted bid strategies.

Why Use RLSA?

• Increased Conversion: Users who have already visited the site convert better than cold traffic.
• Precise Targeting: Ads can be shown only to an interested audience.
• Cost Reduction: It makes sense to bid more for “warm” users than for everyone indiscriminately.
• Ad Personalization: Segments like “abandoned cart” users can be targeted with specific offers (e.g., “Your laptop is back in stock!”).

Where RLSA is Applied

• E-commerce stores
• Service websites
• B2B products
• Banks, insurance, healthcare
• SaaS services
• Any business with a long decision-making cycle

Examples of RLSA Use:

1. Bid Adjustments for Warm Audiences: Increase bids for users who added items to their cart to win the auction.
2. Ad Personalization: Example: “Return to complete your purchase – get 5% off.”
3. Keyword Expansion: While cold traffic campaigns may use only exact match keywords, RLSA campaigns can effectively utilize broader keywords for remarketing audiences.
4. Excluding Unwanted Segments: For example, exclude users who have already purchased a product.

Advantages of RLSA

• High conversion rates
• Ad personalization
• Budget efficiency
• Bid management capabilities
• Audience flexibility
• Ideal for lengthy purchasing decisions

Limitations of RLSA

• A list must contain at least 1,000 users (1,000 for search, 100 for Display/Youtube) to be eligible for ad serving.
• Requires a correctly installed tracking tag.
• Cannot target based on personal data.
• Very small audience sizes are not usable.

Best Practices

• Create multiple lists:
  • Category page visitors
  • Abandoned cart users
  • Returning visitors
  • Viewers of specific products
  • Past customers/purchasers
• Test different bid adjustments for different segments.
• Personalize ad text.
• Use promo codes and urgent offers.
• Exclude segments that have already converted.

Conclusion

RLSA is a powerful Google Ads remarketing tool for search that allows showing ads to users who have already interacted with a website. It increases targeting precision, saves budget, and boosts conversion rates.
