FAQs
1. What is the difference between a technical SEO audit and a content audit?
A technical SEO audit focuses on site performance, crawlability, and indexation, while a content audit examines quality, relevance, and keyword optimization of existing pages.
2. How often should I run a technical SEO audit?
For most sites, quarterly audits are sufficient. High-traffic or frequently updated sites benefit from monthly or even weekly checks.
3. Can I do a technical SEO audit without paid tools?
Yes, free tools like Google Search Console and TechnicalSEO.com can handle basic checks, but paid tools offer deeper insights and automation.
4. Will fixing technical SEO issues immediately improve rankings?
Fixing critical technical issues can lead to fast ranking gains, especially if they were preventing proper indexing. Other improvements may take weeks to show results.
5. What is crawl budget and why does it matter?
Crawl budget is the number of pages search engines will crawl on your site in a given timeframe. Wasting it on low-value pages can harm indexation of important content.
6. Do I need both a cloud-based and a desktop SEO tool?
Not always. Cloud tools are great for automation and collaboration, while desktop tools often provide more flexibility in crawl configurations.
7. What are Core Web Vitals and why are they important?
Core Web Vitals measure load time, interactivity, and visual stability—key factors in Google’s ranking algorithm for user experience.
8. Can a technical SEO audit help with site migrations?
Absolutely. Pre- and post-migration audits ensure no critical pages, links, or metadata are lost during the transition.
9. How do I choose the best tool for my site size?
Small sites can thrive with lighter tools like Sitechecker, while enterprise sites need scalable solutions like DeepCrawl, Lumar, or Botify.
10. What’s the most overlooked technical SEO issue?
Orphaned pages—important URLs with no internal links pointing to them, making them invisible to search engines without direct sitemaps.
