How Airglow identifies it
- DeclaredIt names itself in the User-Agent:
SemrushBot-BA.
Every visit in Airglow says which of these applied, so you can decide how much to trust it.
Seeing it on your site
It reads pages without running JavaScript, so Airglow counts it through a server connection (Cloudflare). It's labeled as context, not replayed.
Allowing or blocking SemrushBot-BA
SemrushBot-BA reads the SemrushBot-BA group in your robots.txt. To keep it out of the whole site:
User-agent: SemrushBot-BA Disallow: /
Airglow shows, for every agent that visits, whether your robots.txt lets it in, and helps you write rules by purpose (training, search, acting for a person).
Blocking one Semrush tool doesn't block the others
Semrush uses a separate robots.txt token for each tool. A group for SemrushBot-BA does not cover SemrushBot, SiteAuditBot or the other tokens on Semrush's bot page. Add a group for each one you want to stop.
