Technical SEO

Technical SEO ensures search engines can effectively crawl, index, and render your website. It's the foundation that makes all other SEO efforts possible.

Even the best content won't rank if search engines can't properly access and understand it. Technical SEO removes barriers between your content and search engine crawlers while optimizing the experience for users.

Crawlability & Indexation

Ensure search engines can discover and index your pages.

Robots.txt

Control which pages search engines can crawl. Be careful not to accidentally block important pages.

XML Sitemaps

Submit a sitemap to help search engines discover all your important pages efficiently.

Canonical Tags

Specify the preferred URL version to avoid duplicate content issues.

Crawl Budget

For large sites, optimize crawl efficiency by fixing errors and prioritizing important pages.

Site Speed & Performance

Fast-loading pages improve user experience and rankings.

Image Optimization

Compress images, use modern formats (WebP), and implement lazy loading.

Code Minification

Minify CSS, JavaScript, and HTML to reduce file sizes.

Caching

Implement browser and server caching to speed up repeat visits.

CDN Usage

Use a Content Delivery Network to serve assets from locations closer to users.

Core Web Vitals

Google's key metrics for page experience ranking.

Largest Contentful Paint (LCP)

Measures loading performance. Should occur within 2.5 seconds of page load.

First Input Delay (FID)

Measures interactivity. Pages should have an FID of 100 milliseconds or less.

Cumulative Layout Shift (CLS)

Measures visual stability. Pages should maintain a CLS of 0.1 or less.

Interaction to Next Paint (INP)

The newest metric replacing FID, measuring overall page responsiveness.

Mobile Optimization

Google uses mobile-first indexing for all websites.

Responsive Design

Your site should adapt seamlessly to all screen sizes.

Mobile Usability

Ensure tap targets are large enough and text is readable without zooming.

Mobile Speed

Optimize specifically for mobile networks and devices.

Viewport Configuration

Properly configure the viewport meta tag for mobile rendering.

Security & HTTPS

Secure websites build trust and rank better.

SSL Certificate

Install and maintain a valid SSL certificate for HTTPS.

Mixed Content

Ensure all resources load over HTTPS, not HTTP.

Security Headers

Implement headers like HSTS, CSP, and X-Frame-Options.

Regular Audits

Monitor for security vulnerabilities and malware.

Structured Data (Schema Markup)

Structured data helps search engines understand your content and can enable rich results in SERPs.
