Frequently Asked Questions
How do I know if I have technical SEO problems?
Start with Google Search Console's Index Coverage and Core Web Vitals reports. They surface most critical issues. Then run a crawl with Screaming Frog or Sitebulb to identify broken links, duplicate content, missing meta tags, and other problems.
Is technical SEO more important than content?
They're both essential. Technical SEO ensures your content can be found and indexed. Great content ensures it ranks and converts. A technically perfect site with thin content won't rank, and great content on a broken site won't be discovered.
How often should I audit my site's technical SEO?
Monitor Search Console weekly for new issues. Run a comprehensive crawl monthly for medium sites, quarterly for smaller sites. Always audit before and after major site changes like redesigns, migrations, or CMS updates.
What's the most common technical SEO mistake?
Blocking important resources from crawling is surprisingly common—either through robots.txt or noindex tags added during development and never removed. Duplicate content issues from URL variations are a close second.
Do I need to hire a technical SEO specialist?
For basic sites, you can handle technical SEO yourself using guides like this one and tools like Search Console. Complex sites, migrations, or persistent ranking issues benefit from specialist help. Many businesses start DIY and bring in experts for specific projects.
