We need to keep the bots out, and luckily, in many cases, it's not too difficult. Bots can be blocked primarily by using a firewall, which can be added to most websites using a service such as Cloudflare or Malcare, or by your hosting provider. These services will block the majority of bots, but still let in the ones you want (hello, Google!). With this in place, you can not only reduce the carbon footprint of your website, you can also improve load speeds, enhance security, and stop competitors from scraping your information. Win!
