Add <link rel="preconnect"> for critical third-party domains (fonts, CDNs, analytics). This saves 100 to 300ms per connection.

High number of scripts. Each one competes for the main thread. Consider bundling, code splitting, or removing unused scripts.

HTML alone is large. Total page weight including assets matters for mobile users on slow connections.

Add includeSubDomains to your HSTS header to protect all subdomains.

Add X-Frame-Options: DENY or use CSP frame-ancestors to prevent your site from being embedded in malicious iframes.

Add a Referrer-Policy header (e.g. "strict-origin-when-cross-origin") to control what referrer information is sent with requests.

Add a Permissions-Policy header to control which browser features your site can use (camera, geolocation, etc.).

Add FAQPage schema markup. AI models like ChatGPT and Gemini heavily rely on structured Q&A data when generating answers. This is one of the most impactful AIO tactics.

Structure some of your content as questions and answers. Use H2/H3 headings phrased as questions followed by clear, concise answers. This is the format AI models are most likely to cite.

Use more definitive statements like "X is...", "X means...", "X works by...". AI models favour content that makes clear, authoritative claims they can quote directly.

Add author information (name, bio, credentials). AI models use authorship as a trust signal when deciding which sources to cite. Add Person schema or visible author bylines.

Add datePublished and dateModified to your structured data, or use <time> tags. AI models deprioritise content without clear freshness signals.

Add "about" or "mainEntity" properties to your schema. This tells AI models exactly what topic your page covers, making it more likely to be referenced.

Summaries and key takeaways are frequently extracted by AI models as direct answers.

Lists and tables are easily parsed by AI models and frequently used in generated responses.

Content with citations and external references is seen as more authoritative by AI models.

Consider expanding your content with more subtopics and sections. AI models favour comprehensive pages that thoroughly cover a topic over thin content.

Use more natural, conversational language. Write as if explaining to a person, not a search engine. AI models prefer content that reads naturally and can be paraphrased easily.
