What Is Technical SEO for WordPress?
Technical SEO for WordPress refers to optimizing your website’s backend structure so that search engines can easily crawl, understand, and index your pages correctly.
Unlike on-page SEO (content and keywords) and off-page SEO (backlinks), technical SEO focuses on:
- Site speed and performance
- Mobile-friendliness
- Crawling and indexing control
- URL structure and canonicalization
- Security and HTTPS
- Structured data (Schema)
Without solid technical SEO, even the best content struggles to rank.
