Core Technical SEO Components
✔Website Performance
Page speed is a critical ranking factor. Google's Core Web Vitals measure user experience through metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
✔Mobile Optimisation
With mobile-first indexing, Google primarily uses the mobile version of your site for ranking. Mobile optimisation includes responsive design, touch-friendly elements, and fast loading on mobile devices.
- Responsive design that adapts to all screen sizes
- Touch-friendly buttons and navigation elements
- Readable text without zooming (16px minimum)
- Fast loading times on mobile networks
⚠Security & HTTPS
HTTPS is a ranking signal and essential for user trust. Security headers protect against common vulnerabilities and improve your site's security posture.
- SSL certificate and HTTPS implementation
- Security headers (CSP, HSTS, X-Frame-Options)
- No mixed content warnings
- Regular security audits and updates
✔Crawling & Indexing
Help search engines discover and understand your content through proper robots.txt, XML sitemaps, and canonical tags.
- Control search engine crawling and include sitemap references
- Help search engines discover all your important pages
- Prevent duplicate content issues and consolidate page authority
✔Accessibility
While not a direct ranking factor, accessibility improves user experience and may provide indirect SEO benefits. It also ensures your site is usable by all visitors.
- Descriptive alt text for all images
- Proper heading hierarchy (H1, H2, H3)
- Sufficient colour contrast ratios
- Keyboard navigation support
