What is a Magento Code Audit?

A Magento code audit is an extensive inspection of a site’s codebase to assess its quality, safety, operation, and compliance with best practices. It encompasses analyzing the source code, extensions, and configurations to detect concerns, weaknesses, and opportunities for upgrading. The Magento technical audit helps guarantee the site’s reliability, scalability, and correspondence to Magento’s standards, facilitating a delightful user path and a more robust online shop.

The Magento code audit service is typically performed by certified Magento 2 developers who prepare a comprehensive report on the code quality of your webstore, potential security gaps, functional complications, and operation obstacles. 

Ultimately, this information empowers you to fix the existing issues, prevent potential troubles, and enhance your site’s codebase to achieve resilient performance.

Magento 2 code audits often include a thorough examination of the following elements:

  • Magento core,
  • Third-party code,
  • Database.

Magento Core

Magento’s architecture adheres to the modularity idea, which allows developers to introduce new capabilities and override existing ones in the platform without modifying its core code. This helps to safeguard the code’s integrity and promotes development processes.

Even so, unskilled developers and those new to the platform may prefer to change the core code rather than write extensions to override the inherent modules. A comprehensive audit of Magento’s core code aids in the identification of issue areas and the avoidance of downtime during future platform updates.

Third-party Code

Using poorly constructed Magento extensions might lead to website performance difficulties. Even if you use extensions from reputable developers, utilizing too many or ones that are incompatible with each other will dramatically slow down your page load time.

Adobe strongly advises developers to adhere to the Magento code standard while creating extensions to maintain consistency and preserve best practices. A thorough audit of your website’s custom code and third-party extensions will assist in identifying issues such as poorly written JavaScript, excessive requests, and other variables that might negatively affect website usability.


Although the database in Magento is rarely the bottleneck in website speed, it cannot be counted out. The site database might get bloated and start underperforming, especially in older sites that have been functioning without maintenance for years.

A database audit aids in the detection of current issues by assessing important performance indicators and discovering typical security flaws such as rogue user rights. Once found, you may put steps in place to make the database faster and more secure.

When Do You Need a Magento Code Audit Service?

Your Magento platform is a complex entity that functions on codes. All the visible front-end functionality is backed by the respective codes in the back-end to maintain your site operation. It is also complemented by multiple extensions modified for your needs, which makes the whole structure even more complicated. The codes and the extensions work as the bricks your store is made of. If any brick gets damaged, the entire website construction can be cracked or ruined.

You can start experiencing minor malfunctions, while neglecting them may lead to larger troubles in the long run. Therefore, we will share several signs that witness the necessity for a Magento audit. Our experience dictates that even if you encounter only one of these concerns, you should take measures, thereby avoiding considerable damage in the future.

  • The site is slow. A sluggish operation may occur occasionally or continually. In any case, it should warn you of potential code issues. A slow operating speed can stem from inefficient or poorly optimized code. A code audit, in turn, can detect performance barriers and advise on elevating speed and responsiveness. 
  • New bugs emerge. Bugs can crawl from minor code flaws, causing user frustration. The emergence of new bugs often indicates underlying code blunders. An audit helps pinpoint and combat these bugs, preventing them from recurring. 
  • Unstable progression. The website development or creation of new features becomes disrupted or inconsistent due to persisting issues occurring on one or the other website’s part. A code audit reveals the core fault and can deliver solutions to ensure smoother development and deployment.
  • The website is unstable. Frequent site crashes or downtime for no obvious reason can also be signs of code imperfections. By inspecting the code, an expert can reveal and rectify the code problems responsible for this instability. 
  • The suspicion of low-quality extensions. Poor-quality or incompatible extensions can adversely affect your site’s function and safety. An audit can evaluate the extensions utilized and advise improvements or replacements.
  • Concerns about incompetent theme implementation. If the website’s design or theme hasn’t been implemented correctly, it can lead to usability issues and a discouraging consumer experience. An audit can assess the theme’s integration and functionality, guaranteeing its accurate application.
  • Security weaknesses. If you suspect weaknesses or have experienced security breaches, an audit helps detect and remove potential gaps in your codebase.
  • Compromised Magento installation. If you have reasons to consider your Magento setup faulty, a code audit will help you uncover vulnerabilities, eliminate malicious code, and avoid security breaches.
  • Post-migration verification. It makes sense to fulfill an audit after migrating to a new Magento version or hosting environment. In these cases, a code audit validates that the code operates appropriately in the new setup.
  • Continuous improvement. Regular Adobe Commerce & Magento code audits help maintain code quality, optimize operation, and guarantee security compliance as your site evolves.

Is A High Abandonment Rate Affecting Your Business?

Our solution includes a new theme with a hot feature set to re-engage customers and boost sales.

Example of a Free Magento SEO Audit by WebMeridian Experts

Recently, our SEO Experts conducted a Magento SEO Audit for an online store specializing in musical instruments and accessories. 

A few words about the project:

  • Site Localization: Ireland
  • eCommerce Platform: Magento (Adobe eCommerce)
  • Theme: Musical Instruments

As part of the SEO Audit, an analysis was conducted in 3 areas:

  • Content of the online store’s categories
  • Technical condition of the site
  • Link mass (external optimization) of the online store

During the Magento SEO Audit, the following errors were identified, which negatively affect the online store’s visibility in Google search and the generation of organic search traffic.

No Subcategories

Categories like

https://**************/shop-by-category/guitars/electric.html do not contain subcategories that would match user queries with specifications. Examples of such queries include:

  • black guitar electric
  • red electric guitar
  • pink electric guitar
  • electric guitar for beginners
  • childs electric guitar
  • fender electric guitar
  • yamaha electric guitar
  • left handed electric guitars
  • acoustic electric guitar
  • irish electric guitar
  • cheapest electric guitar
  • 12 string guitar electric


For such queries, the website should include separate subcategories so that users can directly navigate from Google search results to pages containing only the products that interest them.

eCommerce Website Optimization Solution

Explanation of the error:

Dynamic URLs

The website currently implements subcategories under different brands, which generate dynamic URLs like https://**************/shop-by-category/guitars/electric.html?manufacturer=47, but these are not indexed in Google search as individual pages. As a result, these pages do not appear in Google search results and do not generate impressions and traffic.

An explanation of the error is here.

Example of proper implementation of subcategories:

Category https://onlinestoreexample.com/electric-guitars




https://onlinestoreexample.com/electric-guitars/left handed


Implementing this approach could increase website traffic by 8-10 times. This forecast is based on an analysis of the traffic of competitor https://www.**********.ie , which has organic traffic of 27-40K per month.

Dynamic URLs


  1. Collection and analysis of search queries (study how users search for your products)
  2. Create a structure of relevant pages while adhering to the hierarchy (category, subcategory)
  3. Technical implementation of the correct structure of the online store

Skilled eCommerce SEO experts will analyze your online store for over 120 different parameters. Say goodbye to site crashes with eCommerce SEO audit.

The categories contain errors that reduce the site’s visibility in Google search, or display categories for irrelevant search queries

As an example, the category https://**************/shop-by-category/guitars/electric.html appears for irrelevant queries (“guitars”, “guitars for sale ireland”).

The flaws and gaps in the site’s code or extensions can expose its content to external threats. Hackers may get access to restricted information, inject malicious code into vulnerable areas, infect the site with malware, or even alter website content, disrupting the site’s SEO and reputation.

Our Magento 2 code audit service fights website vulnerabilities by fulfilling an all-encompassing analysis of the codebase and revealing security gaps. Here’s how it works:

  • Detecting weaknesses. We inspect the code for known safety weaknesses, including SQL injection, cross-site scripting, and other troubles.

  • Evaluating custom code. We thoroughly review tailored code to detect and eliminate any vulnerabilities introduced during development.
  • Checking third-party extensions. We evaluate the safety of third-party extensions, uncovering and remedying any issues they may introduce.

Elevate Website UX/UI

Magento is extolled for its superior functionality. However, in their pursuit of abundant features, Magento-powered businesses may sacrifice usability. A Magento code audit is called to balance the functionality, operation, and appearance of your online space.

Our certified team of Magento 2 developers can facilitate website UX and UI design in several ways:

  • Optimize operation. Our experts identify and repair performance barriers that delay the site work. 
  • Establish a responsive design. Code audits check the site’s code and design for responsiveness and the ability to adjust to various screen sizes.

  • Implement usability improvements. By analyzing the code and design, our experts can consult on overall UX improvement, from navigation to user interfaces.

Improve Website SEO

Appearing high on Google’s search results pages is a mighty traffic driver. The top 5 results on a search page get over 67% of all clicks. To elevate your ranking positions in search engines, you should pay attention to the factors they primarily assess:

  • Website performance,
  • Accessibility and usability,
  • Quality of content.

A Magento code audit can aid you in improving these variables with the consequential rise of your site’s ranking position. 

Our Magento сode audit package includes addressing these parameters in several ways:

  • Guaranteeing code correspondence to SEO best practices. Well-structured code and clean markup can facilitate search engine indexing.
  • Optimizing page speed. Code audits resolve operation hindrances that can decelerate the website.
  • Establishing mobile responsiveness. Mobile-adaptive sites are favored by search engines.

  • Checking canonicalization. Proper canonical tags and URL structures are essential for SEO. Code audits review these aspects to remove duplicate content.
  • Inspecting Robots.txt and Sitemap.xml. These files should be present and accurate to ensure correct search engine access and indexing.
  • Reinforcing safety. A safe site is prioritized by search engines. Code audits remove security vulnerabilities that could impact SEO.
