How to Set Up Your robots.txt File
What is a Robots.txt File
A robots.txt file is a plain text file that lives in the root directory of your website. It tells search engine bots, Googlebot, Bingbot, Baidubot, and others, which parts of your site to crawl and which to leave alone. Every major search engine checks this file before it crawls anything else on your domain.
Our free Robots.txt Generator tool lets you build that file without touching code. Choose your rules, select which bots they apply to, block any directories you don't want crawled, set a crawl delay, and add your sitemap, then download the finished file and upload it to your server. Done in under two minutes.
If your site has no robots.txt file at all, crawlers may index pages you'd rather keep out of search results, admin panels, staging environments, duplicate content, thin pages, and internal search results. That wastes crawl budget Google could be spending on your important pages instead.
Google operates on a crawl budget. The number of pages it crawls during any given period is not unlimited. Blocking low-value pages with a properly configured robots.txt file means Googlebot spends its time on the content that actually matters for your rankings.
This online robot.txt generator handles all the formatting automatically. No syntax errors and no missing slashes.
6 Robots.txt Mistakes That Kill Your SEO
1. Accidentally blocking your whole site
The most common and most damaging mistake. Disallow: / under User-agent: * tells every bot to stay off your entire site. One wrong character during a site migration can wipe your rankings. Always check your live robots.txt after any change.
2. Blocking CSS and JavaScript files
Google needs to render your pages to understand them. If your robots.txt blocks your CSS or JS directories, Googlebot sees a broken, unstyled page and may rank it lower as a result. Never block /assets/, /static/, or /js/ unless you have a specific reason.
3. Using robots.txt to hide sensitive data
Blocking a page in robots.txt does not make it private. The file itself is publicly visible at yoursite.com/robots.txt. Anyone can read it, including people looking for pages you didn't want them to find. Use proper authentication for anything genuinely sensitive.
4. Multiple User-agent blocks that conflict
If you list the same bot twice with different rules, the behaviour becomes unpredictable. Keep one rule set per bot and test the result using Google Search Console.
5. Forgetting to update after a site redesign
URL structures change during redesigns. Old robots.txt rules that pointed to /old-blog/ now block nothing, or worse, block new URLs that share part of the path. Review your robots.txt every time your site structure changes.
6. No sitemap reference
Your robots.txt file is one of the best places to point crawlers directly to your sitemap. Leaving it out means some bots may miss it entirely. Add your sitemap URL at the bottom of every robots.txt file.
How Your Robots.txt File Directly Affects Your Google Rankings
Most people treat robots.txt as a technical checkbox. Set it once, forget it. That is the wrong approach.
Your robots.txt file shapes how Google spends its crawl budget on your site. Every site gets a finite number of pages crawled in any given period. If Google is wasting that budget crawling your admin panel, your internal search results, and a hundred duplicate filtered product pages, it is spending less time on the pages you actually want to rank.
The sites that rank consistently well tend to have clean, deliberate robots.txt files. They block what doesn't need indexing, keep the crawl path clear for important content, and reference their sitemap so Google can find new pages fast.
Use this free robots.txt generator to get yours right, then verify it in Google Search Console under Settings > Crawl Stats to see exactly how Googlebot is spending its time on your site.
Which One Should You Use?
They sound like they do the same thing. They don't.
Robots.txt tells crawlers not to visit a page. Noindex tells crawlers not to list a page in search results. The difference matters more than most people realise.
If you block a page in robots.txt, Google cannot read it, but if another website links to that page, Google may still show it in search results as a URL with no description. It knows the page exists, it just can't read it.
If you use a noindex tag, Google can visit and read the page, but it won't include it in search results. That is usually what you actually want when hiding pages from search.
- When to use robots.txt: blocking resource files, admin areas, staging environments, and internal tools that should never be reached by bots at all.
- When to use noindex: thank-you pages, filtered product pages, duplicate content, paginated pages, and anything you want crawled but not ranked.
- When to use both: pages you never want crawled and never want indexed. Apply both to be safe.
Search Engine Bots vs Bad Bots - Who's Crawling Your Site
Not every bot that visits your site is from Google. Some are from legitimate services. Others are scrapers, spammers, and content thieves. Knowing the difference helps you configure your robots.txt file with intention rather than guesswork.
- Bots worth allowing: Googlebot, Bingbot, Slurp (Yahoo), Baidubot, DuckDuckBot, these drive organic traffic and should be allowed on all important pages.
- Bots worth controlling: AhrefsBot, SemrushBot, MJ12bot, SEO tools that crawl your site and consume bandwidth. Not harmful, but worth rate-limiting if your server struggles under the load.
- Bots worth blocking entirely: DotBot, MJ12bot (aggressive), SiteExplorer, and various scraper bots that harvest your content without sending any traffic in return. Block them by name using individual User-agent rules.
Our online robots txt generator includes the most common search engine bots in its configuration panel. For custom bot blocking, add the User-agent name manually to your generated file before uploading.
