# robots.txt and Access Permissions: Is What You Can Crawl the Same as What You’re Allowed to Crawl?

## What Is a Crawling Policy?

**A crawling policy is an operational rule that applies both automated-access directives and the scope of the site owner’s permission.** This note treats a crawling policy in terms of the responsibilities for input, transformation, and output, rather than as the name of a feature. For analysis results to be trustworthy, it must be possible to trace which materials were included, what was checked, and how far the conclusions can extend.

## Why Is This Technology Needed?

Even if a page can technically be opened, that does not establish that crawling permission and permitted use are aligned. Treating restrictions as failure scores can distort the analysis.

## Design Principles and Data Flow

Distinguish automated-crawling directives, permitted scope of use, and access failures. If there are restrictions, determine what can be replaced with approved HTML or captured materials.

> **Check the crawling policy** → **Determine the permitted scope** → **Obtain materials and record restrictions**

Each stage should avoid relabeling the success of the previous stage as an accomplishment of the next. Keeping records of material identifiers, time periods, and verification status makes it possible to locate where omissions and errors occurred and determine what needs to be checked again.

## Connection to the SAG Architecture

SAG records crawling failures and restrictions as separate statuses. Even when browser-based crawling is considered, this does not grant permission to bypass access restrictions.

SAG’s operational value lies in connecting this relationship to pages and questions, comparison results, and improvement tasks. Customers can review both what needs to be supplemented and the basis for decisions, rather than looking at numbers alone. Patterns that require further application should be interpreted according to the scope of the relevant paragraph.

## Illustrative Example and Evaluation Criteria

For example, if automated crawling could not be performed because of a robots directive, that is not grounds for assigning a technical readiness score of 0. Record the uncrawled status and provide a way to submit approved materials.

The example above is intended to explain the structure and calculation; it is not a measured result from a particular customer. An actual report should link the selected period, target, observation conditions, and original records so that the same assessment can be verified again.

## Practical Validation Checklist

| Process stage | What to check |
| --- | --- |
| Check the crawling policy | Distinguish crawling directives from account permissions |
| Determine the permitted scope | Preserve the reason for the restriction |
| Obtain materials and record restrictions | Confirm the permitted scope for replacement materials |

Check that the meaning remains consistent not only with valid inputs but also with empty, duplicate, and differently conditioned materials. Connecting validation items to the completion criteria can reduce the gap between feature descriptions and actual operations.

## Limitations and Application Considerations

The robots directives in RFC 9309 are not access authentication. Site permissions, security measures, and the scope of contractual agreements must be checked separately.

## Research and Official Documentation

- [IETF RFC 9309](https://www.rfc-editor.org/rfc/rfc9309) — Defines robots directives for automated crawling and distinguishes them from authentication.

External materials provide background on the design topic above; they do not certify every SAG implementation or customer result. The application interpretation and illustrative examples in this note are organized according to SAG’s operational structure. Materials checked: 2026-10-06.
