Bot traffic in link analytics: how to filter it and why it matters
A meaningful share of clicks on a freshly shared link are machines. Counting them wrecks every comparison you make.

Where the bots come from
Link preview fetchers from WhatsApp, Slack, Facebook, LinkedIn, Discord and Telegram hit your link the moment it is pasted. Security scanners in corporate mail gateways follow every link in every message. Search crawlers and AI crawlers follow anything public. Uptime monitors hit on a schedule.
Why it distorts more than you think
Bot traffic is front-loaded — it arrives in the first minutes, before humans. A link shared in three Slack workspaces can show a dozen clicks and zero people. On a small campaign that is the difference between "promising" and "flat".
How filtering works
The first pass matches known crawler user agents. The second looks at behaviour: no referrer, no language header, datacentre IP ranges, impossible timing. Neither is perfect, which is why good tools show human and total clicks side by side rather than silently picking one.
AI crawlers are a new category
GPTBot, ClaudeBot, PerplexityBot and others now make up a visible share of automated traffic. Whether you want them counted depends on what you are measuring — they are not customers, but they are not preview noise either.
What to do about it
Report human clicks as your headline number. Set the robots policy on short links so crawlers do not follow them. Exclude your own office and VPN IPs so internal testing does not pollute campaign data. Compare like with like: always human-to-human or total-to-total, never one against the other.
Click limits and bots
If a link has a click limit, bot hits consume it. Combine limits with a nofollow robots policy, or the first few "winners" of your limited offer will be crawlers.
