The robots.txt easy textual content file sits in your root listing and tells well-behaved bots which components of your website they shouldn’t entry.
You possibly can entry the robots.txt for just about any web site by including a /robots.txt to its area. As an illustration, if you wish to see the robots.txt file for DreamHost, add robots.txt on the finish of the area like this: https://dreamhost.com/robots.txt
There’s no obligation for any of the bots to simply accept the foundations.
However well mannered bots will respect it, and the troublemakers can select to disregard the foundations. It’s finest so as to add a robots.txt anyway so the nice bots don’t begin indexing admin login, post-checkout pages, thanks pages, and so forth.
How you can Implement
1. Create a plain textual content file named robots.txt
2. Add your directions utilizing this format:
Consumer-agent: * # This line applies to all bots
Disallow: /admin/ # Do not crawl the admin space
Disallow: /personal/ # Keep out of personal folders
Crawl-delay: 10 # Wait 10 seconds between requests
Consumer-agent: Googlebot # Particular guidelines only for Google
Enable: / # Google can entry all the things3. Add the file to your web site’s root listing (so it’s at yourdomain.com/robots.txt)
The “Crawl-delay” directive is your secret weapon right here. It forces bots to attend between requests, stopping them from hammering your server.
Most main crawlers respect this, though Googlebot follows its personal system (which you’ll management by means of Google Search Console).
Professional tip: Take a look at your robots.txt with Google’s robots.txt testing instrument to make sure you haven’t by accident blocked vital content material.

- Login pages
- Contact varieties
- Checkout processes
- Remark sections
For WordPress customers, plugins like Akismet can deal with this robotically for feedback and type submissions.
Professional tip: Fashionable invisible CAPTCHAs (like reCAPTCHA v3) work behind the scenes for many guests, solely exhibiting challenges to suspicious customers. Use this technique to achieve safety with out annoying official clients.
5. Take into account the New llms.txt Customary
The llms.txt normal is a current growth that controls how AI crawlers work together along with your content material.

Is llms.txt the official normal? Not but.
It’s an ordinary proposed in late 2024 by Jeremy Howard, which has been adopted by Zapier, Stripe, Cloudflare, and lots of different massive firms. Right here’s a rising checklist of internet sites adopting llms.txt.
So, if you wish to soar on board, they’ve official documentation on GitHub with implementation pointers.
Professional tip: As soon as carried out, see if ChatGPT (with net search enabled) can entry and perceive the llms.txt file.
Confirm that the llms.txt is accessible to those bots by asking ChatGPT (or one other LLM) to “Examine if you happen to can learn this web page” or “What does the web page say.”
We are able to’t know if the bots will respect llms.txt anytime quickly. Nonetheless, if the AI search can learn and perceive the llms.txt file now, they could begin respecting it sooner or later, too.
