Glossary entry

What is Bot Traffic?

Bot traffic is non-human visits generated by automated scripts. Some bots are legitimate (search engine crawlers, monitoring tools); many are malicious (scrapers, click fraud, ad fraud, credential stuffing). The 2024 Imperva report estimates 50% of internet traffic is now bot, with 30% malicious.

Types of bots

Good: Googlebot, Bingbot, monitoring services. Bad: scrapers stealing pricing, ad-click fraud bots, account-takeover bots, scalper bots, fake-signup bots. Differentiating them is the job of a modern bot management layer.

How bots inflate ad cost

Click fraud bots click ads to drain competitor budgets or generate fraudulent affiliate payouts. Conversion fraud bots fill out forms with fake leads. Both make your cost-per-real-conversion balloon while reported metrics look fine.
