Frequently Asked Questions
Robots.txt is a text file in your website's root directory that tells search engine crawlers which pages they can and cannot access. It's the first file crawlers check when visiting your site. Use it to block admin pages, duplicate content, or private sections.
An XML sitemap is a file that lists all important URLs on your website, helping search engines discover and crawl your pages more efficiently. It includes metadata like last modified date and priority. Submit it to Google Search Console for better indexation.
Only block pages you don't want indexed: admin areas (/wp-admin/), duplicate content, search results, private sections. Never block CSS, JavaScript, or images as this prevents Google from properly rendering your pages. Don't block pages you want indexed!
Update your sitemap whenever you add, remove, or significantly update pages. For blogs, use dynamic sitemaps that auto-update. For static sites, regenerate after changes. Submit updated sitemaps to Google Search Console to speed up discovery.
XML sitemaps are limited to 50MB uncompressed or 50,000 URLs per file. If you exceed this, split into multiple sitemaps and use a sitemap index file. Most sites won't hit these limits, but large e-commerce sites often need multiple sitemaps.
No! Robots.txt only prevents crawling, not indexing. If other sites link to a blocked page, it can still appear in search results (without description). To prevent indexing, use noindex meta tag or X-Robots-Tag header instead.
