5 ways to prevent spam orders in WooCommerce


WooCommerce spam orders happen when bots or fraudsters place fake orders. These orders clutter your WordPress store’s database, waste your time, and even lead to financial losses from chargebacks. Unlike user registration spam, these spam orders directly impact your sales and operations.

This problem often stems from weak security settings, like open guest checkout, lack of bot protection, and poor validation.

Since WooCommerce doesn’t include built-in tools to prevent spam orders, you’ll need to take extra steps to block them. Let’s get straight into the best ways to stop it.

1. Set up Cloudflare: your first line of defense

When it comes to stopping WooCommerce order spam, Cloudflare is your most effective tool because it can help stop spam before it reaches your site.

While other solutions, such as CAPTCHA, anti-spam plugins, and fraud prevention tools, work by filtering spam after bots interact with your store, Cloudflare blocks bad traffic at the edge, preventing bots from reaching your checkout and registration pages.

Cloudflare is more than just a Content Delivery Network (CDN); it’s a security powerhouse. It provides Bot Fight Mode, Web Application Firewall (WAF) rules, and IP blocking, all of which reduce the load on your store, protect your resources, and keep fraudulent orders from slipping through.

Why set up a personal Cloudflare account if Kinsta already includes Cloudflare?

While writing this article, we asked Kinsta’s support engineers this very question. Their response? Kinsta’s Cloudflare integration provides strong, enterprise-level security, but setting up your own Cloudflare account gives you more control.

Kinsta’s built-in Web Application Firewall (WAF) and bot protection apply platform-wide security rules designed to protect all sites hosted with us. However, a personal Cloudflare account lets you fine-tune security settings for your specific WooCommerce store.

Our support team often recommends that customers set up their own Cloudflare account in front of Kinsta’s. This allows you to:

  • Create custom WAF rules to challenge suspicious visitors on checkout and registration pages.
  • Block entire countries or only allow only regions in which your business operates.
  • Apply additional bot filtering before traffic even reaches your site container.

That said, even without your own Cloudflare account, Kinsta’s support team can still block specific bots or IPs at the container level when needed. But if you want extra control and proactive protection, configuring Cloudflare yourself is the best approach.

How to set up Cloudflare for WooCommerce spam protection

The first step is to sign up for a free Cloudflare account if you don’t already have one. Once signed in, you’ll be taken to the Cloudflare dashboard.

To begin, click on the + Add dropdown, click Existing domain, and then enter the domain of your WooCommerce store. This allows Cloudflare to manage traffic and apply security rules to your site.

After entering your domain, Cloudflare will ask you to select a plan. The free plan is sufficient for most WooCommerce stores, as it includes Bot Fight Mode, basic DDoS protection, and security rules. Select the Free Plan, then click Continue.

Next, Cloudflare will scan your current DNS records. You’ll see a list of records automatically pulled from your existing hosting provider. Make sure your primary domain and subdomains are correctly listed. Click Continue to proceed.

Cloudflare will now provide you with new nameservers. To activate Cloudflare’s security features, you’ll need to update your domain’s nameservers at your domain registrar.

After updating your nameservers, return to Cloudflare and click Done, Check Nameservers. Cloudflare may take a few minutes to detect the changes. Once your site is active on Cloudflare, you can set up bot protection rules.

Enable Bot Fight Mode to Block Malicious Bots

One of Cloudflare’s built-in security features is Bot Fight Mode, which blocks known bad bots before they can interact with your WooCommerce store.

To enable it, navigate to Security > Bots in your Cloudflare dashboard. Locate Bot Fight Mode and toggle it ON.

This will immediately help reduce automated spam orders by preventing bots from reaching your checkout and registration pages.

While enabling Bot Fight Mode, it’s also a good idea to turn on Block AI Bots, which is located right next to it. Our support engineers mention that while this setting isn’t strictly needed for WooCommerce spam prevention, it can help with performance spikes caused by AI bots aggressively scraping your site. These bots often send high volumes of uncached requests, which can slow down your site. By enabling Block AI Bots, you reduce spam-related traffic and prevent unnecessary load on your server, keeping your WooCommerce store running smoothly.

Create a custom WAF rule for WooCommerce spam protection

Cloudflare’s WAF lets you set up rules to filter out spam traffic before it reaches your WooCommerce store. Our support engineers shared examples of two useful rules: one that challenges suspicious visitors on key pages and another that blocks traffic from specific countries.

For checkout and registration protection, the rule should target both the URI path and URL query string. In Cloudflare’s Security > WAF, create a rule named WooCommerce Spam Protection. Set the URI Path to contain /checkout/ and /my-account/ while also adding URL Query String contains wc-ajax=checkout. The action should be a Managed Challenge, which forces suspicious users to verify that they are human before proceeding.

For country-based blocking, create a separate rule in Security > WAF and set the Country field to does not equal United States, Canada, and United Kingdom (or any countries supported by your store). Set the action to Block, ensuring that only visitors from approved locations can access your site.

These rules help prevent both automated spam bots and fraudulent orders from high-risk regions while allowing legitimate customers.

Once done, click Deploy Rule. Cloudflare will now challenge suspicious traffic on these pages, blocking automated spam bots while allowing real customers through.

While Cloudflare is the best first line of defense, you may still need additional filtering at the site level. Plugins come in handy when you need to analyze data within WooCommerce itself, such as:

  • Checking customer details before blocking an order.
  • Filtering out spam registrations based on email domains or IP history.
  • Preventing fake orders that slip past bot protection.

Our support engineers recommend using Cloudflare wherever possible to block spam before it reaches the site. However, if Cloudflare alone isn’t enough, or you’d rather handle spam filtering directly in WordPress, here are some other options to help prevent WooCommerce spam orders.
