What Sitebulb does
Sitebulb is a website auditing crawler for technical SEO. It is not a public bot: it only crawls a site when a Sitebulb user actively initiates an audit. Its default desktop and mobile user agent strings are Chrome-based and include the token Sitebulb/1.1 with a link to sitebulb.com, and users can choose alternative user agents including Google, Bing, Yahoo, and Yandex presets. The Chrome version portion of the string tracks the latest Chrome release, so it changes over time.
How to control Sitebulb
Target Sitebulb in your robots.txt with the Sitebulb token. Rules apply per bot, so you can allow this one while blocking others, or the reverse.
Allow Sitebulb
User-agent: Sitebulb
Allow: /Block Sitebulb
User-agent: Sitebulb
Disallow: /Sitebulb's documentation warns that the Chrome version in its user agent string is regularly updated, so allowlist rules that match the full string need to be kept up to date.
How to identify Sitebulb
Temso identifies Sitebulbtraffic by matching the request's User-Agent header against this pattern. User-agent strings can be spoofed, so treat a match as an indication, not proof.
SitebulbSitebulb FAQ
What is Sitebulb?
Sitebulb is a website crawler used for technical SEO audits. It is not a public bot; it only crawls a site when one of its users actively starts an audit, identifying by default with a Chrome-based user agent containing the token Sitebulb/1.1.
How do I block Sitebulb?
Add a robots.txt group with "User-agent: Sitebulb" and "Disallow: /". Note that Sitebulb users can select alternative user agents such as Google, Bing, Yahoo, or Yandex presets, so audit traffic will not always carry the Sitebulb token, and crawls only happen when a user initiates one.
About SEO & Analytics Crawlers
Crawlers behind SEO and marketing-intelligence platforms: backlink databases, site audits, rank tracking, and brand monitoring.
Blocking these has no effect on search or AI visibility. It mainly limits what third-party tools (including your competitors' tools) can see about your site.
