Question 1

What is robots.txt and is it legally binding?

Accepted Answer

**robots.txt** is a plain-text file at `/robots.txt` (the site root) telling well-behaved crawlers which paths they may access. It's **advisory, not enforceable**, a rule like `Disallow: /admin` doesn't prevent access; it just asks crawlers not to fetch that path. Googlebot, Bingbot, and most legitimate AI crawlers obey it; malicious scrapers don't. For actual access control, use HTTP auth, rate limiting, or WAF rules. robots.txt is a politeness convention with real SEO impact, but not a security mechanism.

Question 2

How do I block AI bots from training on my content?

Accepted Answer

Add User-agent blocks for the known AI crawlers: **`GPTBot`** (OpenAI), **`Google-Extended`** (Google Bard/Gemini training, separate from Googlebot search), **`ClaudeBot`** / **`anthropic-ai`** (Anthropic), **`CCBot`** (Common Crawl, used to train many models), **`PerplexityBot`** (Perplexity), **`Bytespider`** (TikTok/ByteDance). Disallow each with `Disallow: /`. Note: this opts you out of training; it does NOT block search indexing. To block search, also disallow Googlebot etc. (but think carefully, losing search traffic is a real cost). The list of AI crawlers evolves; check this tool's preset for current names.

Question 3

Disallow vs noindex, what's the difference?

Accepted Answer

**Disallow** (in robots.txt) tells crawlers not to FETCH the page. The page may still appear in search results, Google can index URLs based on links from elsewhere even without crawling them. **noindex** (HTML meta tag or X-Robots-Tag header) tells crawlers that DO fetch the page not to INDEX it. Counterintuitive consequence: if you want a page completely out of search results, allow crawling but add `<meta name="robots" content="noindex">`. Disallowing in robots.txt while the page is linked elsewhere can keep it in search results as a URL-only entry without snippet.

Question 4

Where does the sitemap go?

Accepted Answer

In robots.txt, anywhere, as: `Sitemap: https://example.com/sitemap.xml`. The Sitemap directive is not tied to a User-agent block, it applies globally. Multiple sitemaps allowed (one per line). Always use the absolute URL. The sitemap declares URLs you want crawled; robots.txt declares what's allowed. They work together: sitemap is positive ("here's what to crawl"), robots.txt is negative ("don't crawl this"). For a small site, robots.txt alone is fine; for sites with thousands of pages or complex structures, both.

Question 5

Common robots.txt mistakes?

Accepted Answer

**Disallow: /** accidentally**, blocks the entire site from search. The #1 SEO disaster; usually happens when staging robots.txt is deployed to production. **Capitalization confusion**, `Disallow` is case-sensitive in some implementations; paths are case-sensitive (`/Admin` ≠ `/admin`). **Trailing slash matters**, `/admin` blocks `/admin` AND `/admin/anything`; `/admin/` blocks only `/admin/anything` (not the parent page). **No Allow before Disallow narrows correctly**, order can matter on some crawlers; explicit is safer. **Forgetting the sitemap**, easy to add, helps crawlers find content faster.

Question 6

Is anything sent anywhere?

Accepted Answer

No. Generation is pure string templating in your browser. The paths you protect (which might hint at private admin areas, internal endpoints, or unreleased features) stay in the tab. Open DevTools Network during use: zero outbound requests. You copy the output and paste it into your site's `/public/robots.txt` or equivalent.

Question 7
