The Foundation: Technical SEO Checks

Before diving into content optimization, you need to make sure your website's technical foundation is solid. These first few checks will reveal issues that could be silently killing your rankings.

1. Page Speed Analysis

Page speed directly impacts both user experience and search rankings. Google's PageSpeed Insights has made this crystal clear: slow sites get penalized. What to check: Load times under 3 seconds for desktop, under 5 seconds for mobile. Look at Core Web Vitals scores, especially Largest Contentful Paint (LCP) and First Input Delay (FID). How to fix: Compress images, enable browser caching, minimize JavaScript, and consider a content delivery network (CDN). I've seen sites gain 40+ ranking positions just by fixing speed issues.
