For the most part, bots and spiders are relatively harmless.
You want Google’s bot, for example, to crawl and index your website.
However, bots and spiders can sometimes be a problem and provide unwanted traffic.
This kind of unwanted traffic can result in:
- Obfuscation of where the traffic is coming from.
- Confusing and hard to understand reports.
- Misattribution in Google Analytics.
- Increased bandwidth costs that you pay for.
- Other nuisances.
