Linkdex bot — SEO platform crawler
Linkdex was an enterprise SEO platform whose crawler fetched pages to build link and on-page datasets. It is a third-party SEO tool crawler, not a search engine. Because Linkdex has been absorbed into other products over time, this entry describes the documented pattern and is marked partially verified.
What this means
Linkdex was an enterprise SEO platform offering link analysis, rank tracking, and on-page insights, with its own crawler to gather that data. Over time the brand has been folded into other SEO products, so its crawler may appear under legacy identifiers. It is a third-party tool crawler, not a search-engine indexer.
Because the product has changed hands, treat any Linkdex-labelled crawler as a historical or transitional identity and confirm what platform currently operates it.
How the Linkdex crawler identifies itself
Linkdex's crawler self-identified with a Linkdex token and a self-identifying URL in its user-agent string. Because the platform has been absorbed elsewhere and current documentation is sparse, this entry is marked partially verified — match on the Linkdex token if seen, but confirm the operating platform and current token before acting on it.
The user agent is a claim that can be copied; verify where authenticity matters.
- robots.txt token: Linkdex legacy crawler token (verify current operator)
- User agent contained a Linkdex-identifying URL
- An SEO platform crawler, not a search-engine indexer
robots.txt control
A compliant SEO crawler honours robots.txt. To disallow a Linkdex-style crawler site-wide, target its confirmed token with a standard Disallow rule.
Because the brand is legacy, confirm whether the crawler still operates under the Linkdex name before writing a rule, so you target the right token. robots.txt is a request honoured by compliant crawlers, not an access-control mechanism.
How it appears in analytics and logs
A request carrying a Linkdex token is an SEO platform crawler fetching a URL to build link and ranking datasets — a bot event, not a human visit. It reflects SEO data collection and should be counted as crawl coverage, not audience.
Diagnostic use case
Recognise a Linkdex-style SEO crawler in historical or current logs as link/ranking data collection and restrict it via robots.txt if unwanted.
What WebmasterID can help detect
WebmasterID classifies a Linkdex-style crawler server-side as an SEO crawler and surfaces its activity on the bot-intelligence surface, separate from human analytics, so you can see SEO data-collection hits without log parsing.
Common mistakes
- Assuming Linkdex is still an independent live crawler without checking its current operator.
- Treating its data-collection hits as human traffic.
- Writing a robots.txt rule against an outdated token.
Privacy and accuracy notes
Linkdex crawler detection uses only the request user-agent. No human identity is involved. WebmasterID records the crawl as a bot event, separate from human analytics, and never attaches it to a visitor profile.

- Search crawlers vs SEO crawlers
Search-engine crawlers like Googlebot and Bingbot build the indexes that determine search visibility. Third-party SEO crawlers like AhrefsBot and SemrushBot feed analysis tools and do not affect rankings directly. Distinguishing them matters for crawl-budget reasoning and for deciding what to allow or limit.
