Survey Bot
Survey Bot is an SEO crawler operated by Domain Tools. It maps link graphs, ranking signals, and on-page audits, usually for a SaaS product that helps marketers monitor their own or competitor sites.
Volume can be heavy. SEO crawlers often request every page on a site, and several can hit you in parallel if multiple customers are auditing your domain at once.
Most are well-behaved, respect robots.txt, and back off when rate-limited. The trade-off for allowing them is being visible inside the marketing tools your customers and competitors use.

Match the User-Agent header on incoming requests against the pattern below.

For higher confidence, also verify the source IP against the operator's published ranges. UA strings can be spoofed; IP ownership is harder to fake.

Should I let Survey Bot through?
In most cases, yes. Useful to be visible in SEO tooling, but volume can be heavy. Rate-limit to keep the load manageable. If volume gets noisy, rate-limit it before you block it outright.
Does blocking Survey Bot affect my Google rankings?
No. Survey Bot is not a search-engine crawler. Your ranking on Google or Bing is unaffected by what you do here.
How do I confirm a request is really from Survey Bot?
Look at the User-Agent header in your access logs and match it against the strings listed above. Worth knowing that the User-Agent is easy to fake, so this check tells you "the traffic claims to be Survey Bot", not "the traffic is genuinely Survey Bot". If you need stronger guarantees, look for a reverse-DNS check or wait for Domain Tools to publish IP ranges.
Why is a third-party tool crawling my site?
Someone, possibly a competitor running a backlink audit, possibly your own team, set up a job in Domain Tools. The crawler runs on their schedule. Blocking it only blocks their visibility into your site, it doesn't break anything user-facing.
What's the cleanest way to control Survey Bot?
Two layers. Robots.txt for the polite crawlers that read it, and rules at your CDN or edge for the ones that don't. Rankly's Agent Experience handles both from a single config, so you can allow, block, rate-limit, or serve a stripped-down version per bot. Agent Analytics handles the observation half so you know which bots are actually worth a rule.
