WHMCS doesn't have a built-in feature specifically for creating landing pages. However, you can create custom landing pages using HTML, CSS, and potentially some JavaScript, and then integrate them with WHMCS.

Here's a general outline of how you can create landing pages for WHMCS:

1. Create the Landing Page:

   • Use HTML, CSS, and potentially JavaScript to design your landing page. You can use a code editor or a website builder for this.

2. Host the Landing Page:

   • You'll need a place to host your landing page. You can use your own hosting server or use a third-party service.

3. Link to WHMCS:

   • On your landing page, you'll likely want to include links or forms that direct visitors to the relevant WHMCS pages, such as order forms or product pages.

4. Use WHMCS Hooks or APIs (Optional):

   • If you want to integrate your landing page more closely with WHMCS, you can use WHMCS hooks or APIs to perform actions like creating orders or registering new clients directly from your landing page.

5. Test and Optimize:

   • Test your landing page to ensure it works correctly and looks good on various devices and browsers. Monitor its performance and make optimizations as needed.

6. Track Conversions:

   • Set up tracking to monitor how many visitors to your landing page convert into actual clients or customers.

Remember, while WHMCS itself doesn't have a dedicated landing page builder, you have the flexibility to create your own landing pages and integrate them with your WHMCS setup. Additionally, if you're using a content management system (CMS) like WordPress, you can integrate WHMCS into your existing website, including landing pages, using plugins or embed codes.

Always ensure that your landing page complies with best practices for conversion optimization, user experience, and any legal or privacy considerations.
