What Is meta-webindexer?
meta-webindexer is Meta's web crawler that browses the internet to improve search results for Meta AI users. It analyzes online content to make Meta AI's responses more relevant and accurate. When the crawler accesses your website, it allows Meta AI to properly cite and link back to your content when answering user questions, ensuring you get credit while helping the AI provide better information. You can see how often meta-webindexer visits your website by setting up Dark Visitors Agent Analytics.
Agent Type
Expected Behavior
AI search crawlers index websites to power AI-driven search engines, similar to how traditional search crawlers work for Google or Bing. They regularly scan sites to build and update their index, with crawl frequency varying based on content freshness, site authority, and perceived importance. Unlike traditional search engines with relatively predictable crawl schedules, AI search crawlers may visit more sporadically or in bursts depending on their algorithmic indexing priorities.

Frequently Asked Questions About meta-webindexer
Should I Block meta-webindexer?
Generally no. meta-webindexer enables users to discover your content through an AI-powered search engine. These platforms typically provide attribution and link back to original sources, potentially driving traffic to your site. Blocking it may reduce your visibility in those AI search results.
How Do I Block meta-webindexer?
If you want to, you can block or limit meta-webindexer's access by configuring user agent token rules in your robots.txt file. The best way to do this is using Automatic Robots.txt, which blocks all agents of this type and updates continuously as new agents are released. While the vast majority of agents operated by reputable companies honor these robots.txt directives, bad actors may choose to ignore them entirely.

You can verify whether meta-webindexer is respecting your rules by setting up Agent Analytics to monitor its visits to your website.
Will Blocking meta-webindexer Hurt My SEO?

Does meta-webindexer Access Private Content?
AI search crawlers generally only index publicly accessible content, similar to traditional search engines. They typically respect authentication barriers and don't attempt to access private content behind login walls. However, they may index content that's publicly accessible but not intended for search engines, such as staging environments or development sites if they're not gated properly.

Your site was selected for indexing to make your content searchable through their AI-powered search engine.
How Can I Authenticate Visits From meta-webindexer?
Agent Analytics authenticates agent visits from many agents, letting you know whether each one was actually from that agent, or spoofed by a bad actor. This helps you identify suspicious traffic patterns and make informed decisions about blocking or allowing specific user agents.
