What is a robots.txt file?
A robots.txt file is a text document located in a website's root directory that tells search engine crawlers which pages or sections they should or should not crawl. It is a vital tool for managing crawl budget and preventing the indexing of sensitive or redundant parts of a site.
The robots.txt file is essentially a set of instructions for web robots (crawlers). When a search engine like Google visits a site, the first thing it looks for is this file. It uses the 'Robots Exclusion Protocol' to give commands like 'User-agent' (who the rule applies to) and 'Disallow' (which paths should be ignored). While it is excellent for preventing crawlers from wasting time on low-value pages—like your login screens, internal search results, or admin folders—it is important to note that robots.txt is not a guaranteed way to keep a page out of Google's index. If a page is blocked in robots.txt but has external links pointing to it, Google might still index the URL. To truly prevent a page from appearing in search results, a 'noindex' tag is required. Misconfiguring your robots.txt file is a common technical SEO mistake; accidentally disallowing your entire site can lead to a total loss of search visibility, so it must be handled with care.
단계별 가이드
Locate or Create
Ensure a file named robots.txt exists in your site's root directory (e.g., example.com/robots.txt).
Define User-Agents
Specify which bots the rules apply to, using an asterisk (*) for all bots or 'Googlebot' for specific ones.
Set Disallow Rules
List the directories or specific file paths you want to keep private from search engine crawlers.
Add Sitemap Link
Include a direct link to your XML sitemap at the bottom of the file to help bots find your content.
Test for Errors
Use the Google Search Console robots.txt Tester to ensure you aren't blocking important pages.
전문가 팁
- Use 'Disallow' for private or repetitive pages like /wp-admin/ or /search/.
- Never use robots.txt to hide sensitive user data; use password protection instead.
- Keep the syntax simple; complex rules can lead to crawling errors.

Yes, both the filename and the directory paths listed within it are case sensitive.
