Search in 2025 Isn’t Just Google

SEO has always evolved — but in 2025, it’s not just evolving. It’s fragmenting.
Users are no longer starting their search journey solely on Google. Instead, they’re asking questions to ChatGPT, browsing how-tos on YouTube, searching for inspiration on TikTok, or reading AI summaries on platforms like Perplexity or You.com.
This shift means your SEO strategy can no longer be Google-only. To remain visible and competitive, brands must learn how to optimise for a multi-engine world.

What Is Multi-Engine SEO?

Multi-engine SEO is the practice of structuring and distributing your content so that it appears across a wider range of search environments, including:
  • Traditional search engines (Google, Bing)
  • AI assistants and generative engines (ChatGPT, Gemini, Perplexity)
  • Video-based search (YouTube, TikTok)
  • Image and product search (Pinterest, Google Shopping)
  • Voice assistants (Google Assistant, Siri, Alexa)
Each of these platforms uses different signals to surface content. What works for one may not work for another — which is why SEO 2025 is about adapting to multiple search intents, formats, and algorithms.

Why This Matters More Than Ever

Recent studies show that:
  • A growing share of Gen Z users start product searches on TikTok or Instagram
  • Platforms like ChatGPT and Bing Chat are influencing decision-making with summarised responses
  • YouTube remains one of the most-used search engines for how-to and review queries
  • Google’s SGE is changing how results are displayed, with fewer traditional blue links
If your content strategy only focuses on web page rankings, you’re likely missing opportunities to be found where your audience already is.

How to Optimise for a Multi-Engine Landscape

  1. Understand Search Intent Across Platforms
    Different platforms satisfy different types of intent:
    • Google: Best for transactional and informational queries
    • YouTube: Ideal for tutorials, reviews, visual demos
    • TikTok: Discovery, trends, quick tips, product inspiration
    • ChatGPT / Perplexity: Summarised facts, educational content
    • Voice search: Local information, definitions, FAQs
    Tailor your content format and tone based on where it’s likely to be consumed.
  2. Repurpose Core Content Across Formats
    Start with a high-quality blog post or service page. Then break it into:
    • A short-form video for TikTok or Reels
    • A long-form explainer video for YouTube
    • A clear Q&A snippet optimised for voice search
    • Structured paragraphs with sources for AI models to reference
    This approach doesn’t just save time — it builds topical authority across channels.
  3. Use Platform-Specific Optimisation Tactics
    • YouTube: Use keyword-rich titles, descriptions, and captions. Add chapters and strong CTAs.
    • TikTok/Instagram: Focus on engaging hooks, subtitles, and fast-paced delivery.
    • ChatGPT & AI models: Provide concise, well-sourced, semantically rich content that can be referenced in summaries.
    • Google: Continue using structured data, page speed optimisation, and on-page best practices.
    Wherever your content lives, make sure it’s designed for discoverability.
  4. Strengthen Your Brand Signals
    AI-driven engines use contextual clues to determine whether a source is reputable. To improve your chances of being referenced:
    • Use consistent branding across platforms
    • Create content under real authors or experts
    • Maintain strong domain authority with backlinks and citations
    • Link internally to reinforce topic coverage
    This supports visibility both in traditional SERPs and in generative responses.

Multi-Engine SEO in Action: A Real-World Example

Let’s say you’re publishing a guide on “How to create a digital marketing strategy.”

In 2023, you’d likely just write a blog post.

In 2025, a full strategy might include:

  • A written blog post with FAQ schema
  • A summarised version optimised for ChatGPT or Gemini
  • A short video breakdown for TikTok and Instagram
  • A visual explainer uploaded to YouTube
  • A PDF lead magnet shared on LinkedIn
  • Quotes from the article turned into image posts on Pinterest

This cross-platform presence ensures you’re discoverable no matter where the user starts their journey.
