SEO for conversational and multimodal search: a complete guide to 2025

The transformation of SEO beyond Google: when search breathes and sees

The SEO we know is dead. Or rather, it has evolved into something much bigger. By 2025, optimizing for search engines no longer means simply pleasing Google through isolated keywords and strategic links. The revolution lies in understanding that search is now conversational, multimodal, and powered by sophisticated artificial intelligence that processes text, voice, image, and video simultaneously. Virtual assistants like Alexa, Google Assistant, and ChatGPT don’t just answer questions—they interpret complex intentions, understand context, and anticipate needs. According to Gartner projections, by 2027, more than 50% of all searches will be conducted by voice. This is not the future. It’s the accelerated present. For marketing professionals and martech specialists, the message is clear: adapt or become invisible.

Conversational and voice searches: rewriting the DNA of content.

When someone types into Google, the query is short and direct: ‘best CRM for startups’. When someone speaks to an AI assistant, the question changes: ‘What is the best CRM my startup should use if we have a limited budget?’. This difference is fundamental. Voice searches are 40% longer, more contextual, and full of natural language. Natural language processing considers nuances such as accent, speech speed, and environmental context, requiring content that anticipates linguistic variations. Optimizing for conversational search requires a radical shift in keyword strategy. It’s not just about ranking for isolated terms, but about creating content that answers complete questions in a natural and accessible tone. FAQ sections specifically designed for voice queries, content that sounds natural when spoken aloud, and structures that provide direct and contextualized answers have become essential. Brands that have invested in dedicated FAQ pages have seen average increases of 30% in organic traffic. A travel blog that revamped its content to a question-and-answer style, with short summaries at the top, doubled its organic traffic. These are not isolated cases — they are signs of a larger transformation.

Multimodal search: when text, image, video, and voice come together.

The promise of 2025 is multimodal search: different types of input (text, voice, image) combined into a single query for more accurate and contextualized results. Google already works with this technology, allowing users to search using text and images together. But the integration goes further. Emerging multimodal AI models simultaneously process text, image, audio, and video, creating a holistic understanding of the content that generates more relevant answers to complex queries. For marketers, this means rethinking the hierarchy of content. Optimized text acts as a unifying element and semantic anchor between different modalities—providing essential context that allows algorithms to understand relationships between visual, auditory, and textual elements. Infographics with descriptive alternative text, videos with specific timestamps and transcribed content, and audio snippets optimized for voice search have become mandatory components. The strategy is no longer ‘text OR video OR image’. It’s ‘text AND video AND image AND voice’, working in synergy. Tools like SEMrush and Ahrefs include specific features for analyzing conversational queries, identifying long-tail keywords and related questions. Platforms like AnswerThePublic reveal patterns in frequently asked questions, providing valuable insights into potential voice queries that guide the creation of optimized content.

AI-based personalization: content that adapts to the user.

AI doesn’t just process content—it personalizes it in real time. Artificial intelligence-based tools are transforming how we analyze user behavior, performance data, and emerging trends. AI-powered content personalization allows for the creation of multiple versions of the same content for different audiences, the implementation of dynamic content that adapts based on user behavior, and continuous performance optimization through machine learning. This means that two different users can receive completely distinct versions of the same article, optimized for their search intent, device, and interaction history. For martech, the implication is profound: it’s not enough to create excellent content. It’s necessary to create intelligent content that breathes and adapts. Strategies like the Hub and Spoke model—central pillar pages connected to related subtopics through intelligent semantic linking—amplify this effectiveness. Varied and contextually relevant anchor text, bidirectional linking ensuring that related pages link appropriately, and contextual linking placed where it adds genuine value to users transform information architecture into a strategic asset.

The new search landscape: beyond Google

Perhaps the most important insight is this: SEO is no longer just for Google. It’s for the web as a whole—and that includes voice assistants, chatbots, generative AI platforms, and still-experimental neural interfaces. The AI era demands multimodal content that can be processed across different formats and interfaces. Textual, visual, interactive, and auditory elements work together to create comprehensive experiences. This scenario challenges marketers to think differently: don’t just optimize for keywords that generate traffic, but for intents that generate conversions through multiple touchpoints. Invest in tools that use AI to generate detailed reports on user behavior. Update your content to be more conversational. Adapt your strategy for multimodal searches. And stay constantly updated—because in 2025, the only constant is the change accelerated by artificial intelligence.
