How To Find Website Bugs: 8 Effective Methods

To ensure a smooth website experience, it’s important to search for and fix bugs actively. Here are seven tips on how to find website bugs effectively:

1. Perform Cross-Browser Testing

One of the crucial steps in how to find website bugs bugs is to perform cross-browser testing. While a website may function perfectly on one browser, it might encounter compatibility issues on another.

Different web browsers, like Chrome, Firefox, Safari, and Internet Explorer, interpret and render web pages differently. By testing your website across various browsers, you can identify any browser-specific bugs, layout or design inconsistencies, or functionality issues.

Cross-browser testing ensures a consistent user experience across browsers, addressing issues, optimizing performance, and enhancing user satisfaction while reducing critical bugs.

Perform Cross-Browser Testing

2. Utilize Automated Testing Tools

As the second way how to find website bugs, automation testing tools can significantly streamline the bug-finding process. These tools can execute repetitive tasks, identify broken links, validate forms, and perform various checks to ensure website functionality

Here are some popular automated testing tools to consider:

  • Selenium: Useful framework with open and free functionality which can be used to write tests for different browsers and devices.

  • Cypress.io: End-to-end testing tool that is very easy to use and includes built-in functions to create and debug tests.

  • WebdriverIO: Another open source framework, having a wide range of features, offers aspect of browser testing and automation.

3. Find Bugs in Website Manually

While automated testing is helpful, it’s essential not to overlook the importance of manual testing. Manual testing involves a human tester exploring different website sections and thoroughly examining their functionality.

Find Bugs in Websites Manually

By interacting with the website as an end user would, testers can identify issues that automated tools might miss. During manual testing, pay attention to broken links, missing images, formatting errors, device responsiveness, and any other usability or functionality issues.

Testers should also focus on user interface inconsistencies, such as inconsistent font sizes or misaligned elements, to ensure a seamless and visually appealing user experience.

4. Test Input Validation

Websites often accept user input, such as login credentials, search queries, or form submissions. Improper validation of this input can lead to a variety of bugs and security vulnerabilities. As a result, check input validation can be a great way on how to find website bugs.

By systematically testing the input fields and forms on your website, you can identify any issues with data validation and ensure that the website handles user input correctly.

5. Monitor Error Logs

Your website generates a continuous stream of data about its operations, including any errors encountered. These error logs are like whispers from the machine, hinting at potential problems. That’s why control error logs are considered one of the solutions to how to find website bugs.

To utilize error logs for finding website bugs, you should:

  • Enable error logging: Ensure your website is configured to log errors appropriately. The specific method will depend on your server and programming language.

  • Centralized logging: Consider using a centralized logging platform (Fluentd, NXLog, Logstash, etc) that aggregates logs from different sources, making them easier to analyze.

  • Regular monitoring: Don’t just collect logs; actively monitor them for any new errors or spikes in existing issues.

6. Seek User Feedback

Your users are on the frontlines interacting with your website. Their experience can provide valuable insights into potential bugs. Here are some ways to solicit user feedback:

  • User testing: Recruit a group of users to test your website and report on any issues they encounter.

  • Bug reporting tools: Implement a system for users to report bugs they experience easily. This could be a dedicated form, email address, or a widget integrated into your website.

  • User feedback surveys: Include questions in surveys or polls to ask users about their experience with the website and any difficulties they faced.

7. Conduct Security Testing

Security testing is essential for identifying vulnerabilities and potential security-related bugs on a website.

You can engage penetration testers (ethical hackers) to simulate real-world attacks and identify exploitable vulnerabilities. This proactive approach helps you discover and address security issues before they are exploited by malicious actors. .

Conduct Security Testing

8. Watch Session Recordings

A session recording can be used as an effective way of discovering the UX of your website. These recordings basically record every action, such as click, scroll, or mouse movement on your website, so that you can fully understand how your user navigates your site and identify any trouble.

Here’s how session recordings help find website bugs:

  • Identify drop-off points: See where users abandon the website and investigate why. This could reveal confusing navigation, broken forms, or unresponsive elements.

  • Uncover user frustrations: Observe how users interact with your website. Do they hover over certain elements for a long time, suggesting confusion? Do they click on areas that don’t function as intended?

Popular session recording tools to address how to find website bugs include Hotjar, Crazy Egg, and UserTesting.

7 Steps To Fix Website Bugs

After you know how to find website bugs, it is time to resolve them. Here are some steps you can take to eliminate bugs from your site:

7 Steps To Fix And Prevent Website Bugs

Step 1. Debugging

Undoubtedly, debugging takes precedence, and you have two debugging techniques at your disposal:

  • Isolate the bug: Narrow down the scope of the bug by examining the affected code or specific features related to the issue. This helps you focus your debugging efforts.

  • Use Debugging tools: Utilize debugging tools and techniques like browser consoles, logging, and code analyzers to identify errors, trace their origins, and gather relevant information for troubleshooting.

Step 2. Testing

After completing debugs, you need to test them to ensure that all your changes in the system do not generate any other errors:

  • Automated testing: Implement automated frameworks and tools to regularly run test cases. This ensures that any changes or updates to your website are thoroughly checked for bugs and regressions.

  • User testing: Enlist real users or testers to navigate your website and provide feedback. This can uncover usability issues and bugs that may not be immediately apparent during development.

Step 3. Code Reviews

  • Collaborative review: Conduct thorough code reviews to catch bugs early in the development process. Peer programmers can provide fresh perspectives, identify potential issues, and suggest improvements.

  • Code quality standards: Establish coding guidelines and best practices within your development team to promote cleaner and more maintainable code. Consistent adherence to these standards can prevent common coding mistakes that lead to bugs.

Step 4. Version Control

You should use some version control systems, such as Git, to manage your website’s codebase. This allows you to track changes, roll back to previous versions if necessary, and collaborate effectively with team members.

Step 5. Security Considerations

To prevent security-related bugs, it is important to implement security measures like input validation, secure coding practices, and protection against common web attacks (e.g., cross-site scripting, or SQL injection).

Step 6. Regular Updates and Maintenance

  • Keep your software up to date: Apply patches, updates, and security fixes for your website’s CMS, plugins, frameworks, and other components. Outdated software can expose your website to known bugs and security risks.

  • Ongoing monitoring: Regularly monitor your website’s performance, error logs, and user feedback to detect and address any new bugs or issues that may arise.
