In 2025, the way people search online has changed dramatically. Instead of only typing queries on Google, millions of people now ask direct questions to AI chatbots like ChatGPT, Google Gemini, and Perplexity for answers. These chatbots are not just “assistants”, they have become new-age search engines. If your website or brand is not showing up in their answers, you’re missing out on a huge chunk of online visibility.
- ChatGPT processes 1+ billion queries daily and is used by around 190.6 million people every single day worldwide. Its monthly visits are more than 5.7 billion, making it a true rival to Google Search in daily information lookups.
- Google Gemini (integrated into Google products like Search and Chrome) is fast becoming the default AI companion for billions of Google users. While exact daily active user data is harder to isolate (since it blends into Google’s ecosystem), Gemini directly pulls from Google’s indexed pages, making SEO even more crucial.
- Perplexity AI may not be as big as ChatGPT yet, but it has carved out a serious spot with over 10% of the AI search market share in 2025, focusing heavily on community-driven answers from platforms like Reddit, Quora, and social media.
This tells us one thing clearly: Ranking on AI chatbots is the new SEO battlefield. If your website content is visible to these chatbots, you can gain massive organic exposure, authority, and trust.
How ChatGPT Indexes Content
ChatGPT itself doesn’t “crawl” the web like Google does. Instead, it relies heavily on Bing Search to pull live information and references. Microsoft is a major partner of OpenAI, so whenever ChatGPT fetches real-time web data, it actually comes from Bing’s search index.
That means if your website is not indexed on Bing, ChatGPT has almost zero chance of showing your content in its answers.
Why Bing Matters for ChatGPT Rankings
- Bing is the default web search partner for ChatGPT.
- ChatGPT Plus and Pro users also get access to browsing features, which again pull from Bing’s index.
- Unlike Google, Bing has a smaller index size, but this can actually work in your favor. If your site is indexed properly, the chances of being picked up are higher.
- Many studies show ChatGPT answers link to sources like Wikipedia, Reddit, and blogs indexed on Bing more often than obscure sites.
Steps to Rank on ChatGPT Organically
- Add Your Website to Bing Webmaster Tools
- Go to Bing Webmaster Tools.
- Sign in with your Microsoft, Google, or Facebook account.
- Add your website URL and verify ownership (via HTML tag, XML file upload, or DNS).
- Submit Your Sitemap
- Make sure your website has an updated sitemap (usually yourdomain.com/sitemap.xml).
- Submit it to Bing Webmaster Tools so Bing can crawl and index all your pages faster.
- Check for Indexing Issues
- Use Bing’s tools to see if your pages are crawled correctly.
- Fix technical issues like broken links, duplicate content, or missing metadata.
- Optimize for Clarity & Authority
- Since ChatGPT prefers short, structured, and factual content, keep your website content clear and easy to understand.
- Add FAQ sections and schema markup to improve visibility.
Once your site is properly indexed on Bing, ChatGPT can pull your content and even cite your website in answers.
How Perplexity Indexes Content
Perplexity AI is not just another chatbot, it acts more like a “knowledge engine” that blends search results with community-driven answers. Unlike ChatGPT (which uses Bing), Perplexity pulls a lot of its insights from:
- Community platforms like Reddit, Quora, Twitter/X
- Social media discussions
- Google-indexed pages (especially news, blogs, and Wikipedia)
- Direct questions/answers from its own user base
Why Perplexity is Different
- Perplexity focuses on real-time answers and tends to quote from forums and discussions where people answer questions directly.
- Its responses often look like a summary of conversations from Reddit, Quora, and blogs, rather than long encyclopedia-style content.
- Perplexity has about 2 million daily users and over 120 million visits monthly (2025). This is small compared to ChatGPT, but still huge considering the high-intent audience, mostly young professionals, students, and researchers.
How to Rank on Perplexity Organically
- Be Active on Community Platforms
- Write helpful, well-structured answers on Quora and Reddit.
- Provide clear, short, and fact-driven responses because Perplexity prefers crisp content it can easily summarize.
- Leverage Social Media for Authority
- Perplexity often picks content from Twitter/X, LinkedIn, and even YouTube discussions.
- If you’re consistent in posting high-quality insights, Perplexity can reference your posts.
- Keep Content Crystal Clear
- Avoid fluff. Perplexity likes straightforward, Q&A-style content.
- Adding FAQs on your site/blog also improves your chances since it mimics the format Perplexity favors.
- Optimize for Google as Well
- Since Perplexity still uses Google-indexed sites, traditional SEO matters.
- Make sure your site loads fast, has structured data, and is mobile-friendly.
In short, think like a Redditor or Quora writer, not just a blogger. Crisp answers, authority on niche topics, and presence on community platforms = higher chances of Perplexity citing your content.
How Gemini Indexes Content
Google’s Gemini is directly integrated into the Google ecosystem, Search, Chrome, Gmail, YouTube, and Android. Unlike ChatGPT (Bing) and Perplexity (community + mixed sources), Gemini relies almost entirely on Google Search indexing.
This means if your website already follows Google SEO best practices, you’re halfway there. But with Gemini, the rules are a little stricter because it prioritizes high-quality, authoritative content that can be easily summarized.
Why Google Indexing Matters for Gemini
- Gemini only uses Google’s indexed content. If your website isn’t on Google, Gemini cannot see it.
- It pulls from trusted websites (news sites, Wikipedia, official blogs, .gov/.edu sites) more often than random blogs.
- Gemini is designed to reduce misinformation, so it favors sites with E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals.
How to Rank on Gemini Organically
- Master Google SEO Basics
- Submit your site to Google Search Console.
- Keep your sitemap updated.
- Fix crawl errors, broken links, and duplicate content.
- Focus on Authority & Trust
- Use author bios, cite references, and publish expert-written content.
- Get backlinks from high-authority domains.
- Write Content Gemini Loves
- Use FAQ sections, lists, and concise summaries at the top of articles. Gemini often extracts these directly.
- Add structured data (schema markup) to help Gemini understand your content better.
- Leverage Google’s Own Platforms
- Post regularly on YouTube (Gemini pulls video summaries).
- Optimize your Google Business Profile if you’re local.
- Use Google News / Discover optimization if you cover trending topics.
Simply put, ranking on Gemini = ranking on Google, but with extra focus on authority, clarity, and structured information.
Final Wrap-up
- ChatGPT → Focus on Bing Webmaster Tools & Bing indexing.
- Perplexity → Focus on Reddit, Quora, social media, and crisp answers.
- Gemini → Focus on Google SEO, E-E-A-T, and structured content.
This is the new SEO playbook for 2025, your visibility on LLM chatbots is as important as your visibility on Google.
