Detailed Analysis

Warning

No sitemap is declared

The file contains no "Sitemap:" line.

Consequence. Crawlers have to discover every URL by following links. Pages that are deep, newly published, or poorly linked internally take longer to be found, and some may never be. A sitemap is the most direct way to hand a crawler the full list.

If that is not intended. Publish an XML sitemap and declare it with an absolute URL, e.g. "Sitemap: https://example.com/sitemap.xml". The line is global — it belongs outside any User-agent group and applies to every crawler.

Notice

2 rules can never take effect

A broader rule of the same type already covers these paths.

Consequence. These lines change nothing. They are harmless, but they add length to a file that has a size limit, and they make the real policy harder to read.

If that is not intended. Remove the redundant rules, or narrow the broader rule if it is catching more than intended.

Info

4 of 4 AI answer engines are blocked

Blocked: OAI-SearchBot, PerplexityBot, Claude-SearchBot, Google-Extended.

  • OAI-SearchBotOpenAIL207

    ChatGPT search results

    "Disallow: /" blocks OAI-SearchBot.

  • PerplexityBotPerplexityL81

    Perplexity answers

    "Disallow: /" blocks PerplexityBot.

  • Claude-SearchBotAnthropicL183

    Claude search results

    "Disallow: /" blocks Claude-SearchBot.

  • Google-ExtendedGoogleL84

    Google AI Overviews and Gemini grounding

    "Disallow: /" blocks Google-Extended.

If that is the intention. If your intention is to keep the site out of AI-generated answers, the current configuration achieves that.

Consequence. The site cannot be cited as a source in AI-generated answers. Unlike training crawlers these send referral traffic, so blocking them forfeits those visits.

If that is not intended. Remove the matching Disallow rule, or allow these agents on the sections you want cited.

Info

3 of 3 user-triggered AI fetches are blocked

Blocked: ChatGPT-User, Perplexity-User, Claude-User.

  • ChatGPT-UserOpenAIL204

    A ChatGPT user opening this page

    "Disallow: /" blocks ChatGPT-User.

  • Perplexity-UserPerplexityL186

    A Perplexity user opening this page

    "Disallow: /" blocks Perplexity-User.

  • Claude-UserAnthropicL177

    A Claude user opening this page

    "Disallow: /" blocks Claude-User.

If that is the intention. If your intention is to prevent assistants from fetching pages when a person asks for them, the current configuration achieves that.

Consequence. When someone asks an assistant to open a page on this site, it cannot be retrieved. These requests are made because a person asked for that specific page, not to collect content in bulk.

If that is not intended. Allow these agents globally, or only on the sections you want retrievable.

Info

5 of 6 AI training crawlers are blocked

Blocked: GPTBot, ClaudeBot, Bytespider, meta-externalagent, CCBot.

  • GPTBotOpenAIL75

    OpenAI model training

    "Disallow: /" blocks GPTBot.

  • ClaudeBotAnthropicL93

    Anthropic model training

    "Disallow: /" blocks ClaudeBot.

  • BytespiderByteDanceL99

    ByteDance model training

    "Disallow: /" blocks Bytespider.

  • meta-externalagentMetaL96

    Meta model training

    "Disallow: /" blocks meta-externalagent.

  • CCBotCommon CrawlL78

    Common Crawl, widely redistributed as training data

    "Disallow: /" blocks CCBot.

If that is the intention. If your intention is to prevent this content being used as model training data, the current configuration achieves that for these crawlers — the rest of the group is still allowed.

Consequence. These crawlers cannot retrieve content from the site, so it will not be collected as training data. They send no traffic back, and blocking them does not affect search rankings.

If that is not intended. Remove the site-wide block, or replace it with narrower path restrictions.
