Plain-language guides to how search engines and AI answer engines actually work. Start with what GEO means and why AI crawlers see a different web than your visitors do, then work through the practical layers: meta tags, structured data, robots and sitemaps, Core Web Vitals, and how to decide which fixes matter first. Each guide stands on its own, links to the specific checks Sight runs, and stays honest about what is proven versus still emerging.

  1. Performance

    Core Web Vitals in plain English

    Core Web Vitals are three metrics for loading, visual stability, and responsiveness — LCP, CLS, and INP. Here's what each means and the exact thresholds Sight grades against.

  2. GEO basics

    How AI crawlers read your site

    AI answer engines mostly fetch your raw HTML without running JavaScript. If your content only appears after a client-side render, they see an empty shell. Here's what that means.

  3. GEO basics

    llms.txt explained: what it is and who reads it

    llms.txt is a plain-markdown file at your site root that gives AI assistants a curated map of your most important pages. Here's the format and the honest state of adoption.

  4. On-page SEO

    The meta tags that actually matter

    Title, meta description, canonical, and Open Graph tags do most of the work in your HTML head. Here are the length rules and conventions Sight checks, with the exact thresholds.

  5. Workflow

    How to prioritize your SEO fixes

    A long list of issues is only useful if you know what to do first. Here's how to sequence fixes by severity and effort — the same ordering Sight uses to rank your report.

  6. Crawling & indexing

    Robots.txt and sitemaps: a practical guide

    robots.txt controls which crawlers can fetch what; your sitemap lists the pages you want found. Here's how to configure both for search engines and AI bots without accidentally blocking yourself.

  7. Structured data

    An introduction to structured data (JSON-LD)

    Structured data is machine-readable markup that states what a page is about in a typed, unambiguous way. Here are the JSON-LD types worth having and how to test them.

  8. GEO basics

    What is GEO (Generative Engine Optimization)?

    GEO is the practice of making your website visible and citable to AI answer engines. Here's how it works, how it differs from SEO, and where to start.
