SaaS robots.txt Generator

Audit the policy your SaaS serves today, see how documented search and AI crawlers reach real pages, and make explicit changes without guessing or erasing unrelated rules.

A missing scheme is safely normalized to HTTPS. Analyze a registrable domain, one subdomain, or one folder.

What the analysis processes

BloggedBot makes a bounded crawl of public pages. This output is generated deterministically and does not call Gemini.

The Blogged.dev run parsed the live policy, tested nine source-verified crawler tokens against 92 sampled URLs and found no confirmed warning.

Example findings

  • Current policy preserved

    The generator starts from the fetched host-wide file instead of replacing it with a generic template.

  • Search and AI access separated

    Crawler-specific rules are evaluated independently so one user-agent does not stand in for every bot.

  • Risky changes stay gated

    Critical warnings require explicit review before copy or download actions are enabled.

Included outputs

  • Validated robots.txt
  • Crawler matrix
  • JSON evidence
  • Scoped implementation prompt
Direct answer

A good SaaS robots.txt is deliberate, minimal, and tested.

It allows public product, pricing, documentation, evidence, and render assets needed for discovery; blocks only paths the owner intentionally chooses; declares verified sitemaps; and never pretends crawl policy protects private customer data.

Effective-rule audit

Merge matching groups, honor case-sensitive paths and specificity, and show sampled access rather than static labels.

Separate crawler purposes

Keep search, AI citation, training, extended-use, and user-triggered tokens as distinct owner decisions.

Controlled edits

Preserve by default; allow only verified crawler tokens and validated literal path prefixes.

Critical review gate

Require acknowledgment before files that can suppress discovery, rendering, or whole-site crawling are copied or downloaded.

How it works

Inspect, evaluate, choose, and verify.

  1. 01

    Inspect

    Fetch only the root policy within strict network, UTF-8, byte, redirect, and parser boundaries.

  2. 02

    Evaluate

    Apply effective rules to representative SaaS and discovery URLs for each source-verified crawler token.

  3. 03

    Choose

    Preserve existing behavior or make explicit crawler and literal-path decisions with affected-URL previews.

  4. 04

    Verify

    Review critical warnings, download the exact output or scoped patch, then test it on the public host.

The matcher follows RFC 9309 and current Google robots.txt guidance. Crawler identifiers link to official OpenAI, Anthropic, Google, and Bing documentation with a last-verified date.

SaaS robots.txt questions

What does a SaaS robots.txt generator do?

It audits the root policy, applies RFC 9309 matching, shows sampled access for source-verified search, AI-search, training, and user-triggered crawler tokens, then preserves the current file unless you explicitly choose a crawler or literal-path change.

Can robots.txt remove a SaaS page from Google?

Not reliably. robots.txt controls crawling, not authorization or guaranteed deindexing. A blocked URL can still be known from links. Use access control for private data and an indexable response carrying noindex when search removal is the goal.

Should SaaS sites block AI crawlers?

That is a product and content-licensing decision, not one generic switch. The tool keeps AI citation/search agents, model-training agents, Google Search, Google-Extended, and user-triggered agents separate, using only tokens linked to current official provider documentation.

Why does the tool preserve my existing file by default?

Replacing robots.txt can silently change host-wide crawling. The safe default retains comments, Allow and Disallow rules, Sitemap declarations, and unknown extension records. Explicit changes get a before-publish warning and representative URL review.

Can I block a folder or SaaS app path?

Yes, with case-sensitive literal path prefixes after analysis. The tool refuses full URLs, raw wildcards, query strings, fragments, encoded delimiters, control characters, and duplicates, and previews matching sampled URLs. A folder-scoped crawl returns only a review patch.

Will this tool publish or modify my website?

No. It reads authorized public responses and returns a private file, evidence, and repository-aware implementation prompt. You or your coding agent must review, test, and publish the policy.
