Frequently asked questions

What is a technical SEO audit?

A technical SEO audit checks the infrastructure of your website to ensure search engines can crawl, index, and render your pages correctly. It covers robots.txt, sitemaps, canonical tags, SSL, site speed, and more.

Why is robots.txt important for SEO?

robots.txt tells search engine crawlers which pages they can and cannot access. A misconfigured robots.txt can accidentally block important pages from being indexed, causing them to disappear from search results.

What is a canonical URL and why does it matter?

A canonical URL tells search engines which version of a page is the 'original' when duplicate or similar content exists. Without proper canonicals, search engines may split ranking signals across multiple URLs.

Does SSL affect SEO rankings?

Yes. Google confirmed HTTPS as a ranking signal in 2014. Sites without SSL certificates show 'Not Secure' warnings in browsers, which hurts trust and click-through rates. HTTPS is now considered a baseline requirement.

How often should I run a technical SEO audit?

Run a technical audit at least monthly, and always after major site changes like redesigns, migrations, or CMS updates. Our free tool makes it easy to check anytime.
