How do you prepare your online shop for Black Friday to increase user traffic?

Black Friday is one of the most intense events in every online shop owner's calendar. The increase in website traffic on this day can be many times higher than the daily average, which brings both huge sales opportunities and technological challenges. Preparing an online shop for this day requires special attention to infrastructure, scalability and technical optimisation. Here's how to ensure that your shop runs smoothly and is ready for thousands of users.

1. Check your server infrastructure

Increased user traffic puts a lot of strain on the server. To avoid crashes and downtime, it is worthwhile:

• Perform load tests: Tools such as Apache JMeter, Gatling or k6 will help you simulate the increased traffic and see how the server reacts under pressure.
• Use a scalable infrastructure in the cloud: Solutions such as AWS, Google Cloud Platform or Microsoft Azure allow you to dynamically increase resources in real time in response to increased demand.
• Optimise server settings: Configure caching, compression and increase connection limits. Servers with Nginx or LiteSpeed offer more efficient processing of heavy traffic.

1. Take care of page loading speed

Page load speed is crucial during Black Friday - every extra second of loading time can deter customers from making a purchase. Here are the key steps:

• Use a Content Delivery Network (CDN): Services such as Cloudflare or Akamai can speed up the delivery of content to users, regardless of their location.
• Optimise media files: Compressing images using tools such as TinyPNG or ShortPixel can reduce their size without losing quality.
• Use lazy loading: This ensures that page elements, such as images, only load when the user reaches them.

1. Application and database scalability

Not only the server, but also the application and database must be ready to handle heavy traffic:

• Enter horizontal database scalability: Consider using solutions such as replication in MySQL or sharding in MongoDB.
• Take advantage of caching mechanisms: Redis or Memcached can significantly speed up the application by storing the most frequently used data in memory.
• Monitor database queries: Optimise the ones that are slowest and avoid unnecessary real-time queries.

1. Take care of security

More traffic also means a greater risk of cyber attacks, such as DDoS or phishing attempts. To secure your shop:

• Invest in DDoS protection: Services such as Cloudflare or AWS Shield can help protect against malicious attacks.
• Use SSL certificates: HTTPS is a standard that keeps user data secure and builds customer trust.
• Update yoursoftware regularly: Ensure that your content management system (CMS) and plugins are always updated to the latest versions.

1. Ensure high availability

Unplanned downtime can mean the loss of hundreds of potential orders. To prevent this:

• Use a Load Balancer: Load balancing distributes traffic between multiple servers for greater stability.
• Implement data redundancy: Store copies of data in different locations to ensure business continuity in case of failure.
• Schedule backups: Regular backups allow for quick recovery in case of problems.

1. Prepare your shop for mobile users

During Black Friday, a huge proportion of customers shop via mobile devices. Make sure your shop:

• Is responsive: The website should automatically adapt to different screen resolutions.
• Has an optimised shopping process : Shorten the shopping process and provide a simple one-click way to finalise an order.
• Supports fast mobile payment methods: Apple Pay, Google Pay or BLIK are key for mobile users.

1. Monitor in real time

Real-time monitoring allows you to react quickly to problems:

• Install monitoring systems: Tools such as New Relic, Datadog or Zabbix will provide you with detailed information about server and application performance.
• Set up alerts: Set up alerts to inform you of performance drops or technical problems.

How to prepare your online shop for Black Friday to increase user traffic - summary

Black Friday is an opportunity not to be missed. By preparing your online shop technologically properly, you can not only avoid technical problems, but also ensure a positive shopping experience for your customers. Investing in scalability, speed and security is the key to success on this busiest day in e-commerce. Remember: a well-prepared shop is a shop ready for record sales!
