In 2026, users are impatient. Studies show that 47% of users expect a page to load within less than 2 seconds, and 40% will eventually leave a site that loads more than 3 seconds. Honestly, I would do the same, and will probably not wait for a page to load for even 2 seconds. So, Magento 2 merchants have to understand: a slow website is a way to lost clients and profits.
When your store’s performance lags, it doesn’t just cost you traffic; it costs you conversions. Slow load times directly correlate with high bounce rates and cart abandonment. A sluggish site can sabotage your SEO, making it harder for customers to find you in the first place.
That's where this Magento Performance Checklist comes in.
- In each section, there are bullet points for each problem that may happen.
- For each bullet you want to answer “yes”, add yourself 2 points.
- For each bullet you want to answer “sometimes”, add 1 point.
- Write down your score and check the results at the end of the post.
1. Basic Foundation
Before moving to the front-end aspects of your Magento 2 website optimization, you should start with the basic infrastructure. Because if something is wrong with server configurations or code compliance, all the other optimizations will hardly help. So, the first thing to do is to check the server and code performance.
Pay special attention to this point if you face problems like:
Your homepage is taking more than 3 seconds to load.
Category pages lag before products are displayed.
Delays when switching between pages.
A white screen before content appears.
Slow performance in the Magento admin area.

2. Visibility on Google (SEO)
If your website doesn’t show up in Google search results, your potential clients will not see it, no matter how good your products are. Search engine traffic is one of the most important sources of revenue for e-commerce websites. If your organic traffic isn’t growing, your SEO efforts are likely going in some wrong direction.
If you notice these issues, your website could be losing out on valuable organic traffic.
Organic traffic hasn’t increased in the last 6 months.
Traffic decreased after a redesign or migration.
Some pages aren’t appearing in Google search results.
Duplicate pages are appearing in search.
You haven’t done an SEO audit in over a year.
Speed and visibility are two sides of the same coin. Ensure your technical foundation is rock-solid with our Magento 2 SEO Audit to win both Google and your customers.
3. Mobile Version
Having a fast and smooth mobile site is critical for e-commerce success, as people often browse on the go and need clear, intuitive experiences not to bounce off. Poor mobile performance leads to missed sales, so it’s essential to ensure your mobile site runs smoothly.
Problems are definitely present if you identify the following on your mobile Magento 2 website:
Banners are jumping around during loading.
Content shifting after it starts appearing.
Buttons appear with a delay.
Slow opening of the mobile menu.
No immediate response when adding products to the cart.
A fast site is useless if the user interface is confusing.
We combine speed with usability in our Website UI/UX Audit to ensure your fast-loading pages actually convert visitors into buyers.
4. Search and Filters
Search functionality and product filters are some of the most used features on an e-commerce site. If they are slow or inaccurate, your customers may not find what they’re looking for, resulting in a frustrating shopping experience.
Here’s what to look for (and rush for fixes if you find anything from the list):
Slow search performance.
Irrelevant products are showing up in search results.
Category filters are taking too long or "freezing."
Newly added products are not appearing right away.
Products are disappearing or not displaying properly.
5. Cart and Checkout Process
Have you ever quit the shopping process because the checkout stage was full of bugs or didn’t load well? I did. And many other people did as well. A smooth cart and checkout process is crucial for converting visitors into actual buyers. Any delay or issue here could directly lead to abandoned carts and lost sales.
If you've noticed the problems listed below, it's critical to fix them to avoid losing sales at the final step of the buying process.
There’s no clear confirmation after adding an item to the cart.
The cart takes a while to load.
The checkout process sometimes doesn’t display completely.
Customers report issues during checkout.
Some orders fail to go through.
6. Errors and Instability
If your Magento 2 website is full of 404 not founds, broken pop-ups, and other technical errors, it will hardly be treated as reliable and professional by both users and Google. It's essential to identify and address these issues to keep your site stable and running smoothly.
If you're dealing with these issues, it's time for a technical audit to stabilize your store and ensure it runs smoothly:
The site occasionally shows errors.
Some pages return 404 errors.
Issues pop up after updates.
The site experiences downtime occasionally.
There have been instances of data loss.
7. Extensions and Custom Modifications
Magento 2 is a powerful platform, yet it needs extensions and customizations to perform in its full capacity. Still, if you carelessly install every Magento extension you come across, things can become bloated, slow, or even conflict. It’s important to audit the extensions you use to ensure they’re all necessary and optimized.
Consider auditing your extensions to ensure they’re not slowing your site down or causing conflicts. Things to check:
A lot of modules are installed on your site.
Extensions that haven't been updated in a while.
The site slows down after new extensions are added.
You’re unsure about which extensions are actively used.
Numerous custom modifications were added over time.
Are your extensions working against you?
A single poorly written extension can bottleneck your checkout and kill performance. Our experts provide a deep Magento Code Audit Service to clean up the mess.
8. Security
A secure website is crucial not only for protecting your business but also for keeping your customers safe. Magento needs regular security updates, and you must ensure you have backups and two-factor authentication to safeguard against breaches.
If any of these are true, your website may be at risk of a security breach.
Magento hasn’t been updated in more than 6 months.
Regular backups aren’t being made.
Two-factor authentication isn’t enabled for admins.
Suspicious activity has been detected in the admin area.
You haven’t done a security audit recently.
For e-commerce, customer data security is a must-have.
Amasty experts offer a comprehensive Website Security Audit to identify and fix security flaws, ensuring your Magento store stays protected against threats.
9. Conversion and Revenue
Slow speeds, a poor mobile experience, or technical problems can (and actually will) lead to decreased conversions. So, if you’re facing low conversion rates, the problem might not be in poor UX but in poor loading times.
P.S. Don’t neglect UX problems, either. If your site looks like a time-travel to 2015, you should definitely consider some improvements.
The following conversion-related issues may indicate that your Magento store needs performance optimization:
Mobile conversion rates much lower than desktop.
Customer complaints about slow performance.
The site feels sluggish during peak hours.
An increase in abandoned carts.
No tracking of how speed affects sales.
Website Performance Checklist Results
25+ points
If your score falls into the red zone, your Magento store has serious performance issues. Common problems like slow load times, mobile site failures, or technical errors are impacting your user experience, conversion rates, and SEO visibility. At this stage, a comprehensive audit and deep optimization are essential to fix the foundational issues that are costing you sales and traffic. It’s time to act quickly – consider starting with a Magento Performance Audit to pinpoint the exact areas that need improvement.
10 – 25 points
If your score is in the yellow zone, your store is performing reasonably, but there are clear areas for improvement. While the issues may not be critical, they can still affect your customer experience and site performance, potentially resulting in lower conversions and higher bounce rates. Quick optimizations can help, such as improving mobile responsiveness, speeding up your checkout process, or fixing minor SEO issues. It’s recommended to address these problems proactively before they become more serious. Consider a targeted optimization approach with the help of our Magento Optimization Service.
0 – 10 points
A green zone score means your store is running well, with a solid technical foundation and optimal performance in key areas. However, regular maintenance is essential to ensure that your site continues to perform at a high level, particularly during traffic spikes or as you add new features. You’re on the right track, but staying proactive with performance monitoring and periodic audits will help you maintain and further improve your site’s efficiency. Consider ongoing support through services like Magento Support and Maintenance to keep everything running smoothly.
