How to be visible on a specific platform?

Different AI platforms source and prioritise content differently. To maximise your chance of being cited, match your strategy to how each platform works.

ChatGPT (OpenAI / Bing)

How it sources

ChatGPT answers draw from:

  1. Pre-trained model knowledge (from its training corpus)

  2. Live web search via Bing (when browsing mode is enabled) Thus, having content in Bing’s index is crucial.

How to optimise

  • Allow GPTBot to crawl your site so your content may feed future model updates.

  • Submit your site to Bing Webmaster Tools and use IndexNow to notify Bing of content changes.

  • Optimise with Bing-friendly SEO: clear keyword usage, structured content, and quality backlinks.

  • Write short, factual sentences that can be quoted directly.

  • Earn mentions from Wikipedia or authoritative domains (ChatGPT often cites Wikipedia heavily).

Perplexity

How it sources

Perplexity operates as an answer engine: for each user query it conducts live web searches and then cites a small set (e.g. 3–4) of relevant sources. It combines both authoritative domains and community content (reddit, etc.).

How to optimise

  • Rank well on Google and Bing, since Perplexity draws from those indexes.

  • Use question-based headings and give direct answers.

  • Keep pages visibly dated and updated.

  • Engage in forums like Reddit or Quora, linking to your content - Perplexity strongly references community content.

  • Use schema (FAQPage, Article) to clarify structure.

Gemini (Google)

How it sources

Gemini (Google’s AI) relies heavily on Google’s search index and uses top-ranking pages, structured data, and ecosystem signals to generate answers.

How to optimise

  • Make sure all your pages are indexed in Google Search:

  • Submit your XML sitemap in Google Search Console.

  • Use the “URL Inspection → Request Indexing” tool for new or updated pages.

  • Check “Coverage” reports to confirm indexing status and fix errors.

  • Apply traditional SEO best practices: high-quality content, relevance, backlinks, E-E-A-T (experience, expertise, authority, trust).

  • Optimize for featured snippets and FAQ / “People Also Ask” blocks — these often feed into AI overviews.

  • Use FAQPage, HowTo, Organization schema, and aim for inclusion into the Knowledge Graph (via schema sameAs, Wikidata, linked entities).

  • Maintain a consistent brand presence across Google’s ecosystem (YouTube, Google Business Profile, etc.) to reinforce trust.
