How to Optimise Your Website for ChatGPT and Perplexity (Without Rebuilding Everything)

You do not need to rebuild your website to make it readable by ChatGPT and Perplexity. Both tools use web retrieval to find and extract information from existing pages, and there are five specific changes you can make that significantly improve how your site is read, extracted, and cited. Most of them are a few hours of work at most.

How ChatGPT and Perplexity Actually Read Your Website

When ChatGPT or Perplexity retrieves your page to answer a query, it does not experience your website the way a human does. It cannot see images (without explicit alt text), does not click through navigation menus, and does not process JavaScript-heavy content as reliably as static text. What it reads is the raw text content of your page: headings, paragraphs, lists, and any structured data you have added.

If your website is full of vague marketing copy, poorly labelled sections, and no structured data, the AI retrieval system extracts very little. If it is clean, well-structured, and factually specific, the AI can pull useful content and cite it accurately.

Quick Win 1: Check Your robots.txt File

Your robots.txt file tells crawlers whether they are allowed to index your pages. If it accidentally blocks the crawlers that AI tools use (like GPTBot for ChatGPT or PerplexityBot for Perplexity), your site will never be cited regardless of how well-optimised everything else is.

To check: go to yourwebsite.com/robots.txt in a browser. Look for any Disallow rules that block key pages or all pages. If you see Disallow: /, your entire site is blocked from crawlers. The fix is to either remove that rule or add explicit Allow rules for the AI crawlers you want to permit.

To explicitly allow the main AI crawlers, you can add the following to your robots.txt:

User-agent: GPTBot
Allow: /

User-agent: PerplexityBot
Allow: /

Quick Win 2: Clean Up Your Page Headings

AI tools use heading structure (H1, H2, H3) to understand the hierarchy of your content and determine what each section is about. If your headings are vague labels like "Our Services" or "Why Choose Us," the AI cannot extract useful information from them.

Rewrite your key page headings to be descriptive and specific. Instead of "Our Services," use "Bookkeeping Services for Trades Businesses in Victoria." Instead of "Why Choose Us," use "What Makes Our Approach Different from Larger Accounting Firms." These headings give the AI context it can use.

Quick Win 3: Add FAQ Sections to Key Pages

Every key service or product page on your site should have a FAQ section at the bottom. Write five to seven questions using the exact language your customers use when they search or ask AI tools. Answer each one in two to three sentences, starting with a direct response.

Good FAQ question example: "How long does a standard bookkeeping setup take for a new client?"

Poor FAQ question example: "What can I expect from your world-class onboarding experience?"

The first example matches a real customer query. The second is marketing language that no one searches for.

Quick Win 4: Add Schema Markup

Schema markup is a standardised code format that explicitly tells AI tools what your content is. The most valuable types for small businesses are:

• LocalBusiness schema: states your business name, address, phone, category, and service area
• FAQPage schema: marks up your FAQ sections so AI can extract them precisely
• Service schema: describes each service you offer with price ranges, descriptions, and area served

If you are on WordPress, plugins like Yoast SEO or Rank Math add most of this automatically. If you are on a custom site, the markup is added as a JSON-LD block in your page head. A developer can add this in under an hour.

Quick Win 5: Add One Credible External Link Per Key Page

When AI tools evaluate the credibility of your content, outbound links to authoritative sources are a signal that your content is grounded in real information. On your key service pages, add one or two links to credible external sources: an industry association, a relevant government resource, or a well-known trade body.

For example, a financial planner might link to the Australian Securities and Investments Commission page on finding a financial adviser. A physio clinic might link to the Australian Physiotherapy Association. These links signal that your content exists in a legitimate professional context.

This Is a Weekend Project

The five changes above, taken together, represent a meaningful upgrade to your site is AI-readability. You do not need to rebuild anything. You do not need a developer for most of it. Start with robots.txt (15 minutes), then headings and FAQ sections (a few hours of writing), then schema markup (an afternoon or a developer hour), then external links (30 minutes). That is a complete weekend project that will improve your AI visibility over the following weeks.
