Having a referral system for your website can bring several benefits:
Increased User Acquisition: Referral programs can be a powerful tool for acquiring new users. When existing users refer your website to their friends, family, or colleagues, it can attract a new audience who are more likely to trust and engage with your website based on the recommendation from someone they know.
Cost-Effective Marketing: Referral programs can be a cost-effective marketing strategy compared to traditional advertising methods. Instead of spending significant resources on paid advertising or marketing campaigns, you can leverage your existing user base to promote your website through word-of-mouth referrals. This can help you reach a wider audience without incurring high marketing costs.
Higher Conversion Rates: Referral traffic tends to have higher conversion rates compared to other acquisition channels. When users are referred by someone they trust, they are more likely to have a positive perception of your website and be more receptive to your offerings. This can result in higher conversion rates, whether it’s signing up for an account, making a purchase, or taking any other desired action on your website.
Increased User Engagement and Loyalty: Referral programs can foster a sense of community and engagement among your users. By incentivizing referrals, you encourage users to actively promote your website and engage with your brand. This can lead to increased user loyalty and a stronger connection between your users and your website.
Viral Growth Potential: A well-designed referral program has the potential to create a viral effect, where each referred user can bring in multiple new users. As the referred users start referring others, the network effect can lead to exponential growth in your user base.
Measurable and Trackable Results: Referral programs provide a measurable way to track the effectiveness of your marketing efforts. You can monitor the number of referrals, conversion rates, and other key metrics to evaluate the success of your program and make data-driven decisions to optimize it further.
Overall, a referral system can be a valuable addition to your website, helping you attract new users, increase conversions, foster user engagement, and achieve cost-effective growth. However, it’s important to design and implement your referral program thoughtfully, considering factors such as incentives, user experience, and tracking mechanisms to maximize its effectiveness.
In this article we will create a PHP file and a simple HTML demonstration of how the system can work. You will also need to have a database for your website to store the data for your users.
How to create the referral.php (PHP file)
The provided PHP code is used to generate a unique referral URL for a user. Let’s break down the code and understand its purpose:
generateReferralURL($userId):- This is a function that takes a user ID as a parameter and generates a unique referral URL for that user.
- Inside the function, a unique referral code is generated using the
generateUniqueCode()function. - The generated referral code is then stored in the database associated with the user’s account using the
saveReferralCode($userId, $referralCode)function. - Finally, the referral URL is constructed by appending the referral code to the base URL (
https://example.com/signup?ref=) and returned as the result of the function.
saveReferralCode($userId, $referralCode):- This is a function that is responsible for saving the referral code in the database.
- The function takes the user ID and referral code as parameters.
- Inside this function, you would typically write the code to interact with the database and store the referral code in the appropriate table or field. The actual implementation of this function would depend on your specific database structure.
generateUniqueCode():- This is a function that generates a unique referral code.
- The code inside this function would typically include logic to generate a unique code, such as a combination of random characters or any other custom logic.
- In the provided code, a static referral code “ABC123” is returned as a placeholder. You would need to replace this with your own logic to generate a unique code.
Generating the Referral URL:
- After defining the necessary functions, the code sets a value for the
$userIdvariable (in this case, it is set to123as a placeholder). - The
generateReferralURL($userId)function is then called with the user ID as an argument, and the resulting referral URL is stored in the$referralURLvariable.
- After defining the necessary functions, the code sets a value for the
Overall, this code provides a basic structure for generating and storing unique referral codes for users, and constructing referral URLs based on those codes. The actual implementation of the database interaction and unique code generation would need to be customized based on your specific requirements and database structure.
<?php
// Generate a unique referral URL for the user
function generateReferralURL($userId) {
// Generate a unique referral code or use any other logic
$referralCode = generateUniqueCode();
// Store the referral code in the database associated with the user's account
saveReferralCode($userId, $referralCode);
// Return the referral URL
return "https://example.com/signup?ref=".$referralCode;
}
// Function to save the referral code in the database
function saveReferralCode($userId, $referralCode) {
// Code to save the referral code in the database
// You'll need to implement this based on your database structure
}
// Function to generate a unique referral code
function generateUniqueCode() {
// Code to generate a unique referral code
// You can use a combination of random characters or any other logic
return "ABC123"; // Replace with your logic
}
// Get the referral URL for the current user
$userId = 123; // Replace with the actual user ID
$referralURL = generateReferralURL($userId);
?>How to create the index.php (HTML file):
After creating the PHP file, it’s now the time to implement it inside your frontpage (or any other page you want this used).
<!DOCTYPE html>
<html>
<head>
<title>Referral System</title>
<!-- Add your CSS styling here -->
<style>
.share-button {
/* Add your button styling here */
}
</style>
</head>
<body>
<!-- Display the referral URL using the shortcode -->
<p>Share your referral URL: <?php echo str_replace("#REFURL#", $referralURL, "https://example.com/signup?ref=#REFURL#"); ?></p>
<!-- Add the share button -->
<button class="share-button" onclick="shareReferralURL()">Share</button>
<!-- Add your JavaScript code -->
<script>
// Function to share the referral URL
function shareReferralURL() {
// Replace "referralURL" with the actual referral URL generated in PHP
var referralURL = "<?php echo $referralURL; ?>";
// Implement the share functionality based on your requirements
// For example, you can use JavaScript libraries or APIs to open a share dialog or redirect to a sharing page
// Here's a simple example to open the user's default email client with a pre-populated message containing the referral URL
var emailSubject = "Join me on Example Website";
var emailBody = "Hey,\n\nI'm inviting you to join Example Website. Sign up using my referral link: " + referralURL;
var emailLink = "mailto:?subject=" + encodeURIComponent(emailSubject) + "&body=" + encodeURIComponent(emailBody);
window.location.href = emailLink;
}
</script>
</body>
</html> As it’s seen inside the code, this will help your users by enabling them to include their username inside an email for which you have defined a subject line and a body.
Additionally, you’ll need to handle the database operations and integrate the referral system into your existing website codebase. If you would like us to write this part of the tutorial for you, please write to us in the comments section below.
