What is bot traffic?

While it’s true that most eCommerce marketing managers and teams know about “Bot Traffic”, it’s very difficult to know when it’s actually happening on your site.

Let’s start by defining what a “Traffic Bot” is. A traffic bot is an automated software program that simulates the behavior of human users. Which is why it can be very difficult to preemptively detect which traffic is human or which are fraudulent bots.

How bot traffic affects your eCommerce site

  1. DRAINED AD SPEND. Advertisers pay for clicks, and if those clicks are coming from bots instead of real people, that’s money down the drain. Not only that, but bot traffic can skew your analytics and make it difficult to accurately track the effectiveness of your ad campaigns.
  2. NEGATIVE USER EXPERIENCE.  If your website is inundated with bot traffic, it can slow down the loading speed and make it difficult for actual customers to navigate and shop on your site. This can lead to a higher bounce rate and fewer conversions.
  3. INCREASED COST OF ACQUISITION. As mentioned above, when advertisers pay for clicks and they’re fake clicks from bots, you’re effectively paying more for each customer you acquire. This can eat into your profit margins and make it more difficult to scale ad campaigns.
  4. DENIAL OF SERVICE ATTACKS. Bots can halt a site’s network by overwhelming it with traffic. If successful, the attacker can hold the website for ransom (i.e “Denial of Service”) until payment is made.
  5. CONTENT SCRAPING. Hackers can program Traffic Bots to scrape a site for information. This includes text, images, videos, and any other type of media on your site. Excessive content scraping strains the site’s servers and affects its performance, increasing heavy load time and making it difficult for actual users to access the site (from logging into an account to making an actual purchase).
  6. FAKE ACCOUNTS. Bots can also create fake accounts and make fraudulent purchases, which can cost the site money and damage its reputation. Additionally, bots can be used to launch denial-of-service attacks, which can make a site unavailable to legitimate users. All of these factors can have a negative impact on an ecommerce site and its ability to generate revenue. 
  7. CREDIT CARD FRAUD. Traffic bots can be programmed to create fake accounts on ecommerce sites and then use stolen credit card information to make fraudulent purchases. Bots can also be used to test the validity of stolen credit card numbers by making small purchases and then checking if the charges are successful.
  8. MALWARE DISTRIBUTION. Attackers can program bots to visit a site, click certain links, and/or download files to install malware on a user’s computer. Plus, the traffic bot can be used to spread the malware to others by sharing infected links.
  9. GIFT CARD ABUSE. Bots can be programmed to commit an account takeover, use the compromised account to pay for goods from a hacked gift card. In certain cases this appears as attackers using loyalty points to then purchase more gift cards, which were then redeemed for goods.
