Technical SEO
Technical SEO encompasses the server-side and infrastructure optimizations that help search engines efficiently crawl, render, index, and rank your website's content.
Technical SEO is the foundation — without it, great content and backlinks cannot reach their potential. Key areas include: site speed (Core Web Vitals), crawlability (robots.txt, sitemap, internal linking), indexability (canonical tags, noindex usage), security (HTTPS), mobile-friendliness, and structured data.
For JavaScript-heavy applications (Next.js, React), technical SEO also includes server-side rendering vs client-side rendering, hydration behavior, and ensuring crawlers can execute and render your JavaScript.
Indxel is built specifically for technical SEO automation. The CLI validates 15+ technical rules, the CI/CD guard prevents regressions, and the dashboard monitors your technical health over time.

Core Web Vitals
Core Web Vitals are a set of three Google metrics — Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) — that measure real-world user experience.
Crawl Budget
Crawl budget is the number of URLs Googlebot will crawl on your site within a given period, determined by crawl rate limit (server capacity) and crawl demand (page importance).
Robots.txt
Robots.txt is a plain text file at the root of a website that instructs search engine crawlers which URLs they are allowed or disallowed from accessing.
Page Speed
Page speed is the measurement of how quickly a web page's content loads and becomes interactive, typically measured by metrics like Time to First Byte (TTFB), First Contentful Paint (FCP), and Largest Contentful Paint (LCP).
