Frequently Asked Questions
What is a technical SEO audit?
A technical SEO audit is a comprehensive check of your website's backend infrastructure and code to identify issues that prevent search engines from properly crawling, indexing, and ranking your site. It covers crawlability (robots.txt, sitemaps), indexation (canonical tags, noindex), HTTPS security, redirect chains, page speed, mobile-friendliness, and structured data implementation.
How do I check if my site is being indexed?
Use Google Search Console to see which pages are indexed. Check the Coverage report for indexation status, look for "Excluded" pages with reasons like "Noindex tag", "Blocked by robots.txt", or "Duplicate content". You can also use site:yourdomain.com in Google search to see indexed pages. This tool helps identify indexation blockers before they reach search engines.
What are redirect chains and how do they affect SEO?
Redirect chains occur when a URL redirects to another URL that redirects again (e.g., /old → /temp → /final). Each redirect adds latency and wastes crawl budget. Search engines may stop following after 3-5 hops, preventing final page indexation. Fix by updating to direct redirects (/old → /final). Chains also slow down user experience and can dilute link equity.
How do I fix canonical tag issues?
Common canonical tag issues include: missing canonicals (add <link rel="canonical">), self-referencing wrong URL (ensure it points to preferred version), conflicting canonicals (remove duplicates), HTTPS/HTTP mismatches (use HTTPS canonical), and canonical chains (point directly to final URL). Always use absolute URLs, ensure the canonical page returns 200 status, and verify it matches your sitemap entries.
