In today's security landscape, OAuth2 has become a standard for securing APIs, providing a more robust and flexible approach than basic authentication. My journey into this domain began with a critical solution architecture decision: migrating from basic authentication to OAuth2 client credentials for obtaining access tokens. While Spring Security offers strong support for both authentication methods, I encountered a significant challenge. I could not find a declarative approach that seamlessly integrated basic authentication and JWT authentication within the same application.
This gap in functionality motivated me to explore and develop a solution that not only meets the authentication requirements but also supports comprehensive integration testing. This article shares my findings and provides a detailed guide on setting up Keycloak, integrating it with Spring Security and Spring Boot, and utilizing the Spock Framework for repeatable integration tests. By the end of this article, you will clearly understand how to configure and test your authentication mechanisms effectively with Keycloak as an identity provider, ensuring a smooth transition to OAuth2 while maintaining the flexibility to support basic authentication where necessary.
In Selenium automation testing, locators help identify and interact with any element on the web page. For example, ID, Name, ClassName, XPath, CSS Selector, TagName, LinkText, and Partial LinkText are widely used to help you interact with the elements on the web page.
Identifying the elements may be an easy task, but your tests might fail due to the state of the WebElement (e.g., the element is not visible or the element is not clickable at point, etc.). In such cases, the tests might throw different Selenium exceptions such as NoSuchElementException, ElementNotVisibleException, etc.

Just like a well-maintained car runs smoother and lasts longer, a well-maintained eCommerce website delivers a better customer experience and helps your business thrive.
Let’s face it: keeping your online store running smoothly can sometimes feel difficult. But neglecting maintenance can lead to security vulnerabilities, frustrated customers, and ultimately lost sales.
At WPBeginner, we have over 16 years of experience helping users set up and run their online stores. We know what it takes to maintain your eCommerce site easily.
In this article, we will share our top eCommerce website maintenance tips to keep your customers happy and grow your business.
Why Should You Maintain an eCommerce Store?
Running an eCommerce store can be challenging. However, it’s worth investing time and effort in maintaining your website because it helps build trust with your customers, improves search engine visibility, and ultimately leads to more sales.
Here’s how prioritizing WordPress eCommerce maintenance benefits your online store:
Enhanced Security: Outdated software and plugins are prime targets for hackers. Regular updates and security audits can patch vulnerabilities and protect customer data.
Improved User Experience: A smooth-running website with accurate information, fast loading times, and a clear checkout process keeps visitors happy and coming back for more.
Better Search Engine Rankings: Search engines favor websites that are up-to-date and optimized for mobile devices. Consistent maintenance ensures your store ranks higher in search results, leading to increased organic traffic and potential sales.
Reduced Downtime and Costs: Regular backups and proactive maintenance lower the risk of website crashes and downtime. In turn, this saves you from lost sales and the hassle of troubleshooting unexpected issues.
Better Conversion Rates: A well-maintained website is a persuasive salesperson. By offering a secure, user-friendly experience, you’ll be able to convert more visitors into paying customers.
That said, let’s look at some eCommerce website maintenance tips. You can use the quick links below to jump between the different tips:
When it comes to maintaining an eCommerce store, you should first regularly check for updates for WordPress, your theme, and any plugins you use.
These updates often include security patches, bug fixes, and performance improvements. If you have outdated WordPress core or plugins, then they are a prime target for hackers.
In WordPress, you can check for updates from the dashboard and update WordPress with a single click. Simply head to the Dashboard » Updates page and see if a new version is available for download.
Plus, WordPress offers an option to enable auto-updates for your plugins. This way, your important plugins are always updated as soon as a new version is released.
Fresh, informative content is very important for attracting and engaging customers. Outdated product descriptions, inaccurate stock levels, and old blog posts create a negative impression and lead to a poor user experience.
Here’s how to keep your content game strong:
Regular Product Updates: Regularly review product descriptions, pricing, and stock availability. Update information as needed to ensure accuracy and avoid customer frustration.
Content Calendar: Create a content calendar to plan and schedule blog posts, product reviews, and other informative content. This helps you maintain a consistent flow of fresh content that keeps your audience engaged.
Seasonal Promotions: Update your website with seasonal promotions, new product launches, and upcoming sales events. This will keep your customers informed and encourage them to visit your store again.
The next WordPress eCommerce maintenance tip is to create regular backups of your online store.
A backup is a copy of your site’s important files, folders, and databases. It includes plugins, products, themes, settings, core files, videos, and more.
Imagine a power outage or cyberattack erasing all your hard work on your online store. Nightmares aside, website backups are also super important for disaster recovery. You can easily restore your eCommerce store to its previous state if something goes wrong.
The easiest way of creating a backup is by using Duplicator. It is the best WordPress backup plugin that is easy and beginner-friendly to use. Plus, it allows you to schedule automatic backups and save your packages on cloud storage services.
Besides that, there are other manual methods for creating backups of your eCommerce site. For more details, please see our guide on how to back up your WordPress site.
4. Monitor Website Server Uptime
Imagine a potential customer arriving at your WooCommerce store only for it to be down and inaccessible. Servers used by poor-quality hosting services can go down frequently and may stay down for several minutes or hours.
Downtime due to server issues can cost you sales and damage your reputation. It can also have a negative impact on your search engine rankings.
There are different ways to monitor server uptime in WordPress. For instance, you can hire support agencies like WPBeginner Pro Maintenance Services to monitor uptime around the clock.
Alternatively, you can also use tools like UptimeRobot. It will check your online store every 5 minutes and notify you if it’s down via email, SMS, voice calls, and other alerts.
5. Choose the Fastest Hosting Solution With No Downtime
Many hosting services promise 99.9% uptime, but that’s often not true.
Your hosting provider is the foundation of your eCommerce website. They are responsible for storing your website’s data and making it accessible to visitors.
That’s why picking a reliable hosting provider is so important. They will ensure your website loads quickly and remains accessible during peak traffic times. Slow loading times can significantly hurt your conversion rates, so you will want to pick a provider with a strong uptime record and fast server speeds.
To find the fastest WordPress hosting providers, we actually signed up with each provider and thoroughly tested different hosting services. From our tests, we found that Hostinger was the quickest.
Here are the results from the Pingdom speed test for Hostinger:
Did you know that a 1-second delay in page load time can lead to a 7% loss in conversions and a 16% decrease in customer satisfaction?
Website speed is highly important for user experience. Slow loading times can frustrate potential customers and lead to abandoned carts. Plus, they will also hurt your search engine rankings as Google considers page load speed as a ranking factor.
There are several ways you can ensure your eCommerce store is loading quickly. Here are some ways to keep your store running smoothly:
Image Optimization:Optimize product images and other media to reduce file sizes without sacrificing quality. This significantly improves loading times.
Caching: Use a caching plugin to store frequently accessed data and reduce the load on your server. This speeds up page load times for returning visitors.
Content Delivery Network (CDNs): Consider using a CDN to deliver static content, like images and JavaScript files, from servers all over the world. This reduces load times for visitors in different locations.

7. Find and Fix Broken Links
Next, you should check for broken links on your eCommerce store. A broken link is one that’s no longer working, and it happens because the web page is deleted or moved to another location.
As a result, you’ll see a 404 page not found error when trying to access the broken link.
Broken links frustrate customers and harm your SEO. Regularly checking and fixing broken links is vital for a positive user experience.
There are several ways to find and fix broken links on your online store. The easiest and quickest way is by using the Broken Link Checker plugin by AIOSEO.
It is a free plugin that scans up to 200 internal links and helps you redirect them to the right destination. You can view all the 404 error links from your WordPress dashboard and fix them by entering the correct URL or simply unlink them from your website.
Other than that, you can also use SEO tools and perform a complete SEO audit of your site to view the link profile. Or use Google Search Console to find broken links on your site.
Your eCommerce website’s database stores critical information like product details, customer data, and order history. A database organizes all the data and fetches information that users request on your site.
As your online store grows, you will want to do regular database management for optimal performance and security. You can start by removing unnecessary data and improving query speeds, keeping your database running efficiently.
In addition to regular website backups, consider backing up your database separately. This provides an extra layer of protection in case of data corruption or security breaches.
Lastly, ensure your database software is up-to-date with the latest security patches to minimize vulnerabilities.
Your eCommerce website handles sensitive customer data, making it a prime target for cyberattacks. That’s why strong website security is essential to protecting your customers’ information and maintaining their trust.
To start, the first thing you can do is use strong passwords and enable 2-factor authentication. Passwords are your first line of defense against hackers trying to access your site and steal valuable information.
You can also enforce strong password policies for both customer accounts and your own administrative access. This helps prevent unauthorized access to your store.
We also recommend installing a valid SSL certificate to encrypt communication between your website and users’ browsers. This ensures secure data transmission and protects customer information.
You should also invest in a WordPress security plugin and web application firewall (WAF). The security plugin will monitor your site for malware, failed login attempts, and other threats. On the other hand, a WAF will block malicious traffic from reaching your site.
10. Troubleshoot eCommerce Store Maintenance Tasks
Even with the best maintenance practices, errors can happen. Having a troubleshooting plan in place helps you identify and resolve issues quickly.
For example, checking for broken links or optimizing images on a live site could slow down the speed. One way to deal with this is to perform the maintenance tasks on a staging site and push the changes live when ready.
Alternatively, you could put your online store in maintenance mode for a temporary period while you perform all the troubleshooting tasks. Once they’re done, simply disable the maintenance mode.
Besides that, you can also follow these tips to troubleshoot maintenance tasks on your online store:
Error Logs: Monitor your website’s error logs to identify any recurring errors or issues. This helps pinpoint the source of the problem and find solutions.
Testing: Regularly test functionalities like checkout processes, user account features, and payment gateways to ensure they work seamlessly. This proactive approach can prevent customer frustration caused by unexpected errors.
Support Resources: Familiarize yourself with your eCommerce platform’s support resources or have a reliable WordPress developer on hand for assistance with complex troubleshooting.
11. Hire a WordPress Support Agency
As your eCommerce store grows, it can be challenging to keep up with all its maintenance tasks. This is where a WordPress support agency can help.
These are experts who can update WordPress, plugins, and themes, fix bugs and issues, and optimize your online store for performance.
Besides that, some agencies also offer core maintenance tasks like backups, security updates, plugin troubleshooting, theme customization, and on-demand support.
For instance, WPBeginner Pro Maintenance Services is the best WordPress maintenance agency for WordPress businesses. We have 16+ years of experience and have helped over 100,000 users improve their online stores and WordPress websites.
Our professional team can keep your site updated, scan for security threats, run cloud backups, and provide 24/7 support for your peace of mind.
