ChatGPT Search generates synthesized, conversational answers with inline citations instead of ranked blue links. Here's what that shift means for SEO and content strategy.
Core Web Vitals remain a confirmed Google ranking signal in 2026. This guide breaks down the exact LCP, INP, and CLS thresholds, what causes failures, and the fastest fixes to reach 'Good' scores.
Schema markup tells search engines and AI answer engines exactly what your content means. This guide covers Article, Organization, and FAQPage structured data — what each type does and how to implement it.
llms.txt is a plain-text file placed at your site root that gives AI language models structured context about your content — think robots.txt, but for LLMs. Here's why it matters now.
AI search engines don't rank pages — they synthesize answers. AEO adapts your content to be cited by those engines, shifting the game from click-through rates to citation authority.
AEO means structuring content so AI-powered answer engines — like ChatGPT, Perplexity, and Google SGE — can extract, trust, and cite it directly. Here's what every SEO practitioner needs to know.
