The company has partnered with Similarweb to bring advanced LLM (Large Language Model) visibility and performance insights to marketers. This will enable marketers to better understand the visibility and performance of their content in AI-driven worlds like generative search and conversations.
The partnership will allow Similarweb’s exclusive digital intelligence data to be integrated into Rakuten Advertising’s analytics and reporting system. This will enable marketers to better understand how they are represented within AI-driven discovery channels, in which decisions are being made.
A New Layer of Marketing Intelligence
As generative AI platforms revolutionize user engagement for products and services, traditional metrics such as clicks, impressions, and rankings are no longer relevant. The partnership between Rakuten and Similarweb provides a new dimension of intelligence based on visibility within AI responses.
By leveraging large-scale behavioral data, the integrated solution allows advertisers to:
- Track how often their brand appears in AI-generated answers
- Understand the relationship between AI visibility and performance outcomes
- Identify opportunities to improve presence across both traditional and AI-driven channels
This development is particularly important as AI platforms become central to the early stages of the buyer journey, influencing decisions before users even visit a website.

Why LLM Visibility Matters
The idea of LLM visibility is quickly developing as an essential factor in digital marketing. Unlike other conventional search engines, generative AI platforms do not aggregate information; rather, they generate it and provide direct answers to questions, often referencing only a handful of sources.
As noted by industry analysis in recent times, there is an overwhelming trend where a handful of brands succeed in achieving AI-generated response visibility, while others fail to achieve any form of visibility. Further, such visibility is also highly ephemeral in nature.
As such, it is imperative that marketers do not only consider the online existence of content but also its recognition and acceptability by AI platforms.
Impact on the Advertising and Marketing Industry
The Rakuten–Similarweb partnership highlights a fundamental shift in the advertising and marketing landscape.
From Search Optimization to AI Visibility Optimization
For years, SEO has remained the mainstay of digital marketing. Today, the focus has shifted to ensuring the content is optimized for AI, such that it is considered for inclusion in the responses provided by the AI tools.
Emergence of New Performance Metrics
With the rise of AI, the traditional KPIs such as CTR and impressions are being replaced or complemented with new KPIs such as:
- AI Citation Frequency
- LLM Visibility Share
- Influence in AI-Generated Recommendations
This is the era of moving from traffic-based KPIs to influence-based KPIs.
Greater Demand for Data-Driven Insights
With the increasing complexity of AI tools, marketers will increasingly turn to platforms that offer cross-channel intelligence, moving beyond the data-driven insights currently being offered for the digital space.
Integration of Affiliate and AI Marketing
The involvement of Rakuten Advertising points towards the integration of affiliate marketing with AI, where the focus will be on the partnerships and the ecosystem of content.
Implications for Businesses
For businesses operating in competitive digital markets, the implications of this development are significant.
Enhanced Decision-Making
With a better understanding of how AI platforms display the information contained within, businesses can make more informed decisions about the partnerships, content, and media investments.
Improved Customer Acquisition
By optimizing for visibility within the AI space, businesses can acquire customers at earlier stages of the decision-making process, beating the competition to the punch.
Stronger Competitive Positioning
As the space of AI visibility becomes a differentiator, businesses that prioritize the exploration and optimization of the space will reap the rewards.
Need for Continuous Optimization
With the ever-changing responses generated by the AI, businesses will need to continually optimize for visibility within the space.
The Bigger Picture: Marketing in the Age of AI Discovery
The partnership between Rakuten Advertising and Similarweb is a manifestation of this new trend in consumer engagement with digital content. Search engines are now becoming answer engines, in which AI systems directly curate and display the information to the consumer.
In this new scenario, the fight for consumer engagement is no longer about appearing in the results list but about being included in the answer itself.
This new trend has several implications for the industry as a whole:
- Marketers need to ensure that they have high-quality and authoritative content that AI trusts
- Marketers need to ensure that their marketing strategies are aligned to consumer intent and information needs
- Data and analytics platforms need to be developed to cater to AI-related analytics
As AI further changes the way consumers engage with digital content, being visible in AI will be as important, if not more important, than being visible in search.
Challenges Ahead
The opportunities are tremendous, but there are also challenges to be faced in the new arena of AI-based marketing strategies. The challenges are:
- Measurement Complexity: To understand the AI-based marketing visibility, new tools and techniques have to be developed
- Content Governance: Ensuring accuracy and consistency in AI-based marketing contents
- Platform Dependency: Over-reliance on AI-based marketing platforms created by others
It is important for businesses to overcome these challenges to succeed in the new arena.
Conclusion
The partnership between Rakuten Advertising and Similarweb signals a major turning point in the history of digital marketing. By bringing together the power of LLM visibility and performance intelligence, the partnership offers brands the opportunity to succeed in a world that is rapidly moving towards artificial intelligence.
The message for the world of advertising and marketing is clear: the future of marketing is about the power of artificial intelligence and the way in which it receives and displays information.
The businesses that adapt to this change will be the ones that succeed in a world where visibility is no longer about being seen, but about being chosen by artificial intelligence.
