Ask ten people how to improve a website's SEO and you'll get ten answers about keywords. Keywords matter, but they're the last mile of a much longer road. Search engines rank websites that are fast, secure, trustworthy, and genuinely useful — and most of what makes a site rank well is decided by unglamorous fundamentals long before anyone writes a blog post.
This is the complete checklist we run on every website we launch, and it doubles as a practical roadmap for improving a site that's already live. Start with the foundation: your domain, DNS, and SSL certificate. Both the apex domain and the www version should resolve, one should permanently redirect to the other, and your SSL certificate should be valid and renewing automatically.
HTTPS has been a Google ranking signal for years, and browsers now actively warn visitors away from insecure sites. While you're at it, run a security-header check — HSTS, content-type protections, and sensible headers signal a well-maintained site to both browsers and crawlers. If your site has ever changed URLs, every old address should 301-redirect to its new home so you keep the ranking equity you've already earned instead of scattering it across dead pages.
Performance is next, and it's measured. Google's Core Web Vitals — how fast your main content paints (LCP), how stable the layout is while loading (CLS), and how quickly the page responds to interaction (INP) — are direct ranking inputs. The common culprits are oversized images, fonts that load late, and JavaScript that blocks the first paint.
Compress and properly size images, preload what the first screen needs, and defer everything else. A site that loads in under three seconds on a phone doesn't just rank better — it converts better, because visitors stop leaving before the page finishes. Mobile isn't a checkbox, it's the primary experience.
Google indexes the mobile version of your site first, so if the phone experience is cramped, broken, or requires sideways scrolling, that's the version your rankings are built on. Test on real devices and across browsers — Chrome, Safari, Firefox, and Edge all render slightly differently.
