💡 high

💡 critical

💡 high

Details: Incorrect canonicals are a top cause of indexing failures — each AI Content Creation post should have a canonical pointing to its own URL, not the homepage or category page.

💡 high

Details: LCP is usually the hero image or H1 text. Use next-gen formats (WebP/AVIF), lazy load below-fold images, and preload your LCP element with <link rel='preload'>.

💡 high

💡 high

💡 medium

Details: llms.txt is a new standard telling AI crawlers which AI Content Creation pages to prioritise. List your top pillar pages with one-line descriptions.
