Maintain a logical heading order (H1 > H2 > H3). Skipping levels hurts accessibility and makes your content structure unclear to search engines.

Consider using H3 tags to create sub-sections under your H2s. This adds depth to your content structure.

Add descriptive alt text to every image. It is essential for accessibility, helps Google understand your images, and enables image search traffic.

Add explicit width and height attributes to images. This prevents Cumulative Layout Shift (CLS) which is a Core Web Vitals metric.

Convert images to WebP or AVIF. These modern formats are 25 to 50% smaller than JPEG/PNG with no visible quality loss.

Links with href="#" or "javascript:void(0)" provide no SEO value. Replace them with real URLs or buttons.

Very low text-to-HTML ratio. Your page has too much code relative to visible content. This can signal low quality to search engines.

Add a twitter:title. Without it X/Twitter falls back to og:title, which may not be optimised for the platform.

Add a twitter:image. X/Twitter may not always use your og:image as fallback.

HTML is above average. Most well-optimised pages are under 100KB of HTML. Check for inline scripts, SVGs, or excessive markup.

Too many inline style blocks. Move CSS to external stylesheets for better caching and smaller HTML.

Many inline scripts found. Consider moving them to external files for better caching and reduced HTML size.

Multiple render-blocking resources detected. Add async/defer to scripts and consider inlining critical CSS.

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

Add Strict-Transport-Security header to force HTTPS. Without it, the first visit to your site may still use HTTP.

Add "X-Content-Type-Options: nosniff" to prevent MIME type sniffing attacks.

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.

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.

Publication/modification dates help AI models prioritise recent, up-to-date content.

Clear entity definitions help AI models understand exactly what your page is about.

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.

Comprehensive, well-sectioned content is more likely to be cited by AI as an authoritative source on a topic.

Natural, conversational language aligns well with how AI models generate responses.
