Technical SEO Checklist: Key Areas & Detailed Actions

1. Website Architecture & Navigation

• Logical Hierarchy: Build intuitive main categories, subcategories, and use breadcrumb paths to organize content.​

• SEO-Friendly URLs: Use hyphens, avoid dynamic parameters, and include relevant keywords.

• Internal Linking: Link between related pages contextually. Anchor text should be descriptive and natural.
  Why? Good architecture enhances crawlability, reduces orphan pages, and improves user experience.

2. Optimizing Website Crawlability

• XML Sitemap & Robots.txt:

  • Maintain a comprehensive, updated sitemap and submit to search engines.

  • Review robots.txt to block only unnecessary pages, never important resources.

• Crawl Error Management:

  • Monitor Google Search Console for 404s, server errors, and crawl blocks.

  • Fix broken links and redirect obsolete pages with 301 redirects.

3. Mobile Optimization

• Responsive Design: Ensure all content adjusts for mobile (fluid grids, flexible images).​

• Touch Optimization: Thumb-friendly buttons, readable font sizes, and no intrusive pop-ups.

• AMP: Consider Accelerated Mobile Pages for news and blog content for top speed delivery.

4. Site Speed & Core Web Vitals

• Speed Up Your Site:

  • Compress images and use WebP format.

  • Minify CSS/JS/HTML files.

  • Leverage browser caching and CDN (Content Delivery Network).

• Optimize Core Web Vitals:

  • Largest Contentful Paint (LCP): Target under 2.5s

  • Cumulative Layout Shift (CLS): < 0.1

  • Interaction to Next Paint (INP): < 200ms

5. Structured Data & Schema Markup

• Schema.org Markup:

  • Use JSON-LD format for articles, products, and local business info.

  • Test markup using Google’s Rich Result tool.

• Why? Schema unlocks rich results and boosts contextual understanding for Google, which means higher rankings.

6. Duplicate Content Management

• Canonical Tags:

  • Mark preferred versions of each page to prevent index dilution.

• Content Audits:

  • Use tools to find and address duplicates, near-duplicates, and keyword cannibalization.

• 301 Redirects: For merged, moved, or deleted content.

7. HTTPS & Security

• SSL Certificate:

  • Use HTTPS for all pages and subdomains; set up 301 redirects from HTTP.

• Security Headers & Audits:

  • Deploy Content Security Policy (CSP), HSTS, and keep software up-to-date.

8. Crawl Budget & Indexation Controls

• Prioritize Valuable Content:

  • Use noindex/nofollow tags for thin or low-value pages.

  • Audit log files to see what Googlebot is crawling most often.

9. Regular SEO Audits

• Tools:

  • Google Search Console, Screaming Frog, Ahrefs, Sitebulb.

• What to Check:

  • Index coverage, performance scores, structure, mobile usability, crawl errors, page speed.
