Technical SEO Checklist for WordPress Websites (2026 Guide)
July 18, 2026 | admin | 4 min read
If your WordPress website isn’t ranking well on Google, technical SEO could be the missing piece. Even the best-written content can struggle to rank if search engines cannot crawl, understand or index your website properly.
This complete technical SEO checklist will help you optimise your WordPress website for better rankings, faster loading speeds and an improved user experience.
What Is Technical SEO?
Technical SEO refers to optimising your website’s infrastructure so that search engines like Google can easily crawl, index and understand your pages.
Unlike content SEO, technical SEO focuses on your website’s speed, security, mobile usability, structured data and overall performance.
1. Make Sure Your Website Uses HTTPS
Google considers HTTPS a ranking factor. Your website should always use an SSL certificate to protect visitors’ data.
- Install an SSL certificate
- Redirect HTTP to HTTPS
- Update internal links
- Fix mixed content warnings
2. Improve Website Speed
Fast-loading websites provide a better user experience and often rank higher in search results.
Ways to Improve Speed
- Choose reliable WordPress hosting
- Enable page caching
- Compress images
- Minify CSS and JavaScript
- Reduce unnecessary plugins
- Enable GZIP compression
- Use browser caching
- Use a CDN for global visitors
3. Optimise Core Web Vitals
Core Web Vitals measure how users experience your website.
| Metric | Recommended Score |
|---|---|
| Largest Contentful Paint (LCP) | Under 2.5 seconds |
| Interaction to Next Paint (INP) | Under 200ms |
| Cumulative Layout Shift (CLS) | Below 0.1 |
4. Ensure Your Website Is Mobile Friendly
Google primarily uses the mobile version of your website for indexing. Every page should display correctly on smartphones and tablets.
- Responsive design
- Readable fonts
- Proper spacing
- Fast mobile loading speed
- Clickable buttons
5. Submit an XML Sitemap
An XML sitemap helps search engines discover your pages more efficiently.
Most WordPress SEO plugins automatically generate one.
- Submit it to Google Search Console
- Keep it updated automatically
- Remove unnecessary pages
6. Fix Crawl Errors
Regularly monitor Google Search Console for indexing and crawling issues.
Common problems include:
- 404 pages
- Redirect loops
- Blocked resources
- Server errors
- Duplicate URLs
7. Optimise Your Robots.txt File
Your robots.txt file tells search engines which sections of your website should be crawled.
Do not accidentally block important pages.
8. Add Structured Data
Schema markup helps Google understand your content and can improve your appearance in search results.
Useful schema types include:
- Organisation
- Local Business
- Article
- FAQ
- Breadcrumb
- Review
9. Optimise URL Structure
Keep URLs short, descriptive and keyword focused.
Example:
Good:
https://example.com/technical-seo-checklist
Avoid:
https://example.com/?p=123
10. Fix Duplicate Content
Duplicate pages confuse search engines.
Use canonical tags where appropriate and avoid publishing identical content across multiple URLs.
11. Optimise Images
- Compress every image
- Use descriptive filenames
- Add ALT text
- Use WebP format where possible
- Lazy load below-the-fold images
12. Check Internal Linking
Internal links help Google discover your content and distribute authority across your website.
Link related blog posts and service pages together naturally.
13. Remove Broken Links
Broken links create a poor user experience and can affect SEO.
- Replace broken links
- Redirect removed pages
- Regularly audit your website
14. Improve Website Security
Secure websites build trust and reduce the risk of malware or hacking.
- Keep WordPress updated
- Update plugins
- Update themes
- Use strong passwords
- Enable two-factor authentication
15. Monitor Performance Regularly
SEO is an ongoing process.
Review your website monthly using tools such as:
- Google Search Console
- Google Analytics 4
- PageSpeed Insights
- Lighthouse
