Technical SEO Issues
Technical SEO Issues is an SEO topic covered in SeoWiki.
Key takeaways
- Common technical SEO issues include HTTPS problems, indexation errors, missing XML sitemaps, robots.txt mistakes, noindex tags, slow page speed, duplicate versions of pages, incorrect canonicals, duplicate content, broken links, weak structured data, and mobile usability problems.
- Google Search Console is a primary tool for finding technical SEO problems because it surfaces indexing, Core Web Vitals, and mobile usability issues.
- robots.txt can block crawling if disallow rules are too broad or incorrect, which can prevent important URLs from being discovered.
