Search Engine Crawler

What is Gigabot?

Gigabot is the crawler behind Gigablast's search index. The catalog describes Gigablast as a U.S. search engine outside Big Tech that uses its own index and algorithms, so this traffic represents collection for that search system.

Nothing in the record ties Gigabot to generated answers or model training. Its ordinary search role is not evidence of an AI use, and allowing it only has a documented effect on Gigablast's ability to collect the page.

The recorded user agent is simply Gigabot, with no browser wrapper or version. That makes matching straightforward but says little about the sender. The entry has no verified IP range or Web Bot Auth directory.

A fetch gives Gigablast content that it could evaluate for its index. It does not confirm inclusion or appearance for a query. Robots.txt compliance is unconfirmed in the bot metadata, and Cloudflare's bot directory marks it as false, so mandatory blocking needs verification or direct enforcement.

Relevant for AI search

Is Gigabot relevant for AI search?

Yes. Gigabot collects pages for an AI product, so what it can crawl influences how AI systems describe your brand.

Gigabot feeds a search index that also powers that engine's AI answer features and overviews. One crawl can serve a classic results page and a generated summary, so blocking it costs you both the rankings you would expect and a growing share of AI answers built on the same index.

How to handle Gigabot

Allow Gigabot if the site wants its public pages considered for Gigablast's index. To opt out of future crawling, state:

User-agent: Gigabot
Disallow: /

Robots.txt behavior is not confirmed, and Cloudflare's bot directory records noncompliance. Check logs after publishing the directive and use an edge rule when the block must be enforced. Never treat the short Gigabot header as authorization to bypass normal access controls.

Examples

  • A niche directory leaves public listing pages open because it wants them available to Gigablast's own search index.
  • A log analyst sees the bare `Gigabot` header on an unexpected route and checks request behavior instead of assuming the sender is verified.
