Ecommerce Website Audit


Once your online store is up and running, you'll want to see how it performs in search results. You also need to know whether it's secure and user-friendly. And how it measures against the competition.

You can start with an ecommerce website audit. An audit can uncover valuable insights into your SEO performance and other factors affecting the user experience (UX). It's also an opportunity to determine what you do well and what you could do better.

What Is an Ecommerce Website Audit?

A website audit reviews your site's performance, functionality, and content. It’s like a health checkup for your blog, business website, or online store.

So, if you run an online shop, you'll conduct an ecommerce website audit. 

You'll look at factors like:

  • Page load speed
  • Mobile-friendliness
  • Website navigation
  • Organic rankings 
  • Keyword usage
  • Content quality
  • Internal linking
  • Security
  • Accessibility

These aspects may impact your search engine rankings and the user experience. Analyzing them helps you spot potential issues and identify improvement opportunities.

Why You Should Perform a Website Audit

A website audit can uncover potential vulnerabilities, errors, and performance issues. It may also reveal opportunities to optimize your content, pages, and overall site structure for higher visibility in search results.

These insights can help you improve your SEO strategy and deliver a better user experience (UX). 

Other potential benefits include:

  • Detect potential issues early on: Detect technical problems before they escalate. For example, you may realize a particular plugin or code is slowing down your site and causing visitors to leave.
  • Optimize your conversion rates: In a 2022 survey, 37% of buyers said they would leave an ecommerce site that's difficult to navigate or has a poor layout. Another 33% would do the same if a website took too long to load. Regular audits allow you to identify and fix these issues to keep visitors on your site longer. This may result in a better user experience and increased sales.
  • Uncover growth opportunities: An ecommerce site audit can reveal your top-performing pages and user behavior trends and patterns. Use these insights to craft better content and personalize the customer experience.
  • Prevent data breaches: The best SEO audit tools can uncover security issues that could lead to data breaches. Such vulnerabilities may include outdated plugins, malicious code, weak passwords, and old security protocols. 

Just like your car needs regular checkups, your website requires ongoing maintenance. From broken links to non-secure pages, many things could go wrong. 

You can use the following checklist to work through a website audit.

5 Key Areas for an Ecommerce Website Audit

A comprehensive audit isn't limited to website performance, security, and SEO. It also accounts for factors like UX and accessibility, which can directly impact sales.

For example, failure to meet accessibility standards can negatively affect the customer experience and lead to hefty fines. Over the years, several consumers sued Netflix, Amazon, DoorDash, and other top brands for being inaccessible to users with disabilities.

The same happened to Nike. Consumers accused it of using empty text links and failing to use alt text on its site. These blunders made its content inaccessible to screen readers.

This ecommerce website audit checklist covers your five main focus areas.

1. Website Performance

Website performance refers to page load speed and other factors that impact a site's functionality.

It also measures time to first byte (TTFB). This term describes how long a user's browser takes to get the first piece of information (byte) from a server after accessing a web page. 

A good TTFB is 0.8 seconds or less. The lower this number, the faster a web page will load. That means users will wait less time to see the content they want, which can improve their experience. And a better UX can contribute to higher search engine rankings

Page load speed and other web performance metrics can affect UX. They matter from an SEO perspective, too.

According to Deloitte, even a 0.1-second improvement in site speed can boost conversions and cause retail consumers to spend around 10% more. It may also increase session duration, engagement rates, and page views. 

How to Audit Your Website’s Performance 

To check a website's performance, access Site Audit from your Semrush dashboard. You'll find it under "SEO" > "ON PAGE & TECH SEO" on the left side of the page.

If you’ve never created a project or audit in Semrush enter your domain name in the “Enter Domain” text box. Then, click “Start Audit.” entered into Site Audit tool

If you have created projects or site audits, click "Create project" on the right side of the page. 

create project button highlighted

Enter your domain name and click "Create project." You will not see this screen if you’ve never created a project or site audit. 

domain entered into project field

Semrush will open a pop-up window with several options for setting up the tool. 

Choose whether you want to audit your entire website, a subdomain, or a subfolder. 

Select a crawl source, such as your website or a sitemap. You can also limit the number of checked pages per audit. 

The checkbox to “Send an email every time an audit is complete” is automatically checked. You can choose to uncheck this option if you don’t want periodic audit updates emailed to you. 

site audit settings popup with crawl scope, number of checked pages, and crawl source

When finished, click "Start Site Audit." Our tool will analyze your site and return the results within 24 hours.

The auditing process can take up to 24 hours, depending on site size and other factors. 

Once the auditing process is complete, check out the "Site Performance" block in the Site Audit Dashboard’s “Thematic Reports” section. You'll see a performance score (0-100%). The higher the number, the better.

Click "View details" for further insights.

The Site Audit tool will take you to a page where you can see your average page load speed and other performance issues, such as large page sizes and long redirect chains.

Click "Why and how to fix it" next to each error on your dashboard. Semrush will detail how that issue affects your website's performance. And what to do about it.

The tool may also issue warnings. These are less severe performance issues, but you should still address them at some point.

Check the "Avg. Page (HTML) Load Speed" section. Here, you’ll see the average load time for your site’s pages.

average page load speed is .12 sec for this domain

In the above example, the average page loading time is 0.58 seconds. That's good, considering Deloitte's recommended page load time is one second or less.

Address other performance issues Semrush's Site Audit tool flags as they arise. See our guide to improving page speed for further recommendations. 

2. User Experience (UX)

UX is how users feel when interacting with a website, product, or service.

For example, a Baymard Institute survey of 1,012 U.S. consumers in 2024 looked at the most common reasons for cart abandonment. Of the respondents, 17% said they abandoned their shopping carts over the past three months because the website had errors or crashed.

Another 22% of respondents said they left without buying because the checkout process was too long or complicated.

Ensure your website delivers a seamless shopping experience. Otherwise, you could miss out on potential customers and sales.

UX and SEO go hand in hand. Optimizing your pages for search engines can improve the user experience. But first, you must audit your site to identify usability issues and other problems affecting the customer journey.

How to Perform a UX Audit

A UX audit involves collecting and analyzing qualitative (e.g., customer feedback) and quantitative data. The latter may include:

  • Organic traffic: The number of users who arrive on your website from organic (unpaid) search results
  • Click-through rate (CTR): The percentage of users who click on a link divided by the number of visitors who saw the link
  • Bounce rate: The percentage of sessions that last 10 seconds or less, don’t trigger any key event (e.g., clicking a button), or include fewer than two page views or screen views
  • Dwell time: How long someone spends on a web page from the moment they click on it in search engine results until they leave it and return to the search results
  • Session duration: The amount of time a user spends on your website during a single visit
  • Page views: The number of times users have loaded a web page in a browser
  • Conversion rate: The percentage of visitors who took the desired action (e.g., buying a product)

For example, the average bounce rate across most industries was 44.82% in August 2023, according to a Databox report. If your numbers are significantly higher, you may need to revamp your website design and other factors affecting UX.

You can track these metrics with Semrush’s Organic Traffic Insights or a combination of Google Analytics 4 (GA4) and Google Search Console (GSC).

GA4 and GSC are web analytics tools. Organic Traffic Insights lets you view data from Semrush and both Google tools on a single dashboard. Simply connect Organic Traffic Insights with your Google accounts

Our tool will show you where your visitors come from and how long they spend on your site. It can also measure your conversion rate, bounce rate, average engagement time, and other valuable metrics.

Leverage this data to see where you stand against the competition and identify UX friction points.

Let’s say you check your site with the Organic Traffic Insights tool and realize most users are leaving a particular page. Use Semrush's Site Audit tool to check for potential technical issues. 

If everything looks right, review the page copy and design. Make changes as needed. You may also conduct A/B testing to compare two versions of the page. 

For instance, one version could have a different title, copy, or lead image. Change only one element (e.g., page title) at a time and test the new version against the original version to see which performs better. 

With this approach, you’ll know exactly what element impacted the results.

3. Technical & On-Page SEO

Technical SEO improves your website's structure and code to help boost its visibility in search results.

On-page SEO involves optimizing your copy, internal links, and other on-page elements.

A technical and on-page SEO audit can help you identify broken external links, missing alt attributes, pages with low word count, and more. These issues can affect your search engine rankings and conversion rates if left unaddressed.

For instance, broken links—whether internal or external—can negatively impact UX. These hyperlinks point to pages that no longer exist.

When users encounter broken links, the server returns a 4xx status code, such as a 404 error. Here's an example from Lego:

Lego's 404 error page with lego man running with scared face

Visitors cannot access the content they seek. This can lead to frustration, high bounce rates, and missed sales.

How to Perform a Technical and On-Page SEO Audit

Use the Site Audit tool to review technical aspects and on-page elements potentially hindering your SEO efforts.

Let's say you want to start with a technical audit. Log in to your Semrush account, select the Site Audit tool, and set up a project (as described earlier in this guide).

Next, click "Issues" in the top navigation menu.

Check the list for any technical errors, such as:

You can scroll down the page and find a list of warnings and notices. These are less severe issues, but you should still fix them for optimal search performance.

Click on an error, warning, or notice to see which pages or website elements require attention.

Next, click "Why and how to fix it" to get more information.

Moving forward, follow our recommendations to solve these technical issues.

You can also use our ecommerce website audit tool for on-page SEO audits. Check your site for on-page errors, such as:

  • Missing or duplicate title tags
  • Pages with too many links
  • Pages with missing meta descriptions
  • Pages with a low text-HTML ratio

In the example below, the website has 50 pages with missing meta descriptions.

A meta description is a text snippet that summarizes a web page's content. Its role is to summarize a webpage for users and search engines.

If you see this error, click on it. Semrush will list the pages where you should add meta descriptions.

4. Accessibility

Web accessibility involves making your site usable to everyone, including consumers with disabilities.

Centers for Disease Control and Prevention reports 27% of U.S. adults have some sort of disability. For example, 6.1% live with deafness or have difficulty hearing. Another 4.8% are blind or have vision problems.

These people could be potential customers. But you risk losing sales and revenue if they can't access your web pages, blog posts, and product descriptions. Your reputation may suffer, too.

A 2024 study of one million homepages detected 56,791,260accessibility errors, from missing alt text to empty buttons. Here’s what the researchers found:

  • 81% of homepages had low-contrast text
  • 54.5% were missing image alt text
  • 44.6% had empty links
  • 48.6% didn’t have form input labels
  • 37.9% skipped heading levels (e.g., jumping from H2 to H4)
  • 28.2% had empty buttons
  • 13.2% used ambiguous anchor text (the clickable text in a link)

Image alt text, for instance, describes the content of a picture for screen readers.

Your product images may not be accessible to visually impaired users if they lack alt text. This can result in higher bounce rates, lost revenue, and dissatisfied customers.

How to Run an Accessibility Audit

Web accessibility audits help you identify the issues listed above, such as missing alt text and improper heading tags.

Heading tags range from H1 to H6. The H1 tag is the main title of a web page. These elements can improve website navigation and make your content accessible to screen readers.

Check your site with Semrush's Site Audit tool. Again, head to your dashboard and click "Issues" from the top navigation menu.

site audit tool issues list

Next, look for accessibility issues like:

  • Missing title tags
  • Missing H1 tags
  • Missing anchor text 
  • Links with non-descriptive anchor text
  • Pages with more than one H1 tag
  • Pages without meta descriptions
  • Images without ALT text

You can click on each error, warning, or notice to see what you need to change. For example, if some of your pages don't have a title tag, manually add these elements.

8 pages don't have title tags error

If you use WordPress for your online business, install Yoast SEO, Rank Math, or the All in One SEO (AIOSEO) plugin. Enter the desired title tag (H1) into the designated plugin field for each page you want to optimize.

WordPress and other content management systems allow you to type the title tag in the text editor. Here’s what the H1 tag looks like:

on the left is html code for the h1 tag and on the right is how the h1 tag appears on the webpage as seen by a user

Also, optimize your videos, product categories, buttons, and copy.

For example, add captions to videos. Captions ensure your content is accessible to users with hearing impairments.

Use descriptive and meaningful anchor text if your blog posts link to product categories or individual products. This text helps search engine bots understand your site structure and provides context to people using screen readers. 

Don't just say, "Click here to find out more." A better option is "Browse our selection of winter jackets" or "This winter jacket was designed to [...]."

5. Security

Web security helps safeguard your website against cyberattacks. 

Baymard Institute reports 25% of 1,012 online shoppers surveyed in 2024 abandoned their carts over the past three months. 


Because they felt uncomfortable sharing their credit card information with the vendor.

Cart abandonment and lost sales are only part of the problem. A poorly secured website is also vulnerable to data breaches and other cyber threats that could:

  • Erode customer trust
  • Compromise customers' data
  • Result in lawsuits and hefty fines
  • Damage your reputation
  • Lead to revenue loss and bankruptcy
  • Affect your SEO and marketing efforts 

A 2023 IBM report states data breaches cost companies with fewer than 500 employees an average of $3.31 million. Unsurprisingly, many small business owners never recover from a cyberattack.

How to Perform a Website Security Audit

Website security audits help detect potential vulnerabilities cybercriminals could exploit. These may include but are not limited to:

  • Missing HTTPS (hypertext transfer protocol secure)
  • Expired SSL (Secure Sockets Layer) certificates
  • Outdated themes or plugins
  • Improperly configured permissions
  • Inactive user accounts
  • Weak passwords

For example, HTTPS encrypts data transferred between websites and browsers.

HTTPS tells consumers your site is secure and can help with SEO. HTTPS is a confirmed ranking signal and can impact your website’s position in search results.

To start the audit, access your Semrush dashboard and click “Site Audit" from the left-side menu. Next, click "Issues" from the top navigation bar. Then, select "Security & HTTPS" from the drop-down menu under "Category."

Our tool will display your site's most critical security errors and a list of warnings and notices.

Click on each error, warning, or notice to see which areas of your site were compromised. You can also click "Why and how to fix it" to better understand the problem you're dealing with and how to solve it.

pop up shows more about the https issue and how to fix it

Run a security scan with Sucuri SiteCheck, Metasploit, or the Website Vulnerability Scanner from Pentest Tools for additional insights.

Sucuri SiteCheck is easier to use but more basic than the Website Vulnerability Scanner and Metasploit. It shows whether or not your site is blacklisted and can detect common issues, like:

  • Internal server errors
  • Injected spam
  • Malware
  • Missing security headers
  • Missing firewalls

Use these findings to determine the steps needed to secure your site.

For example, you could redirect HTTP to HTTPS and set up multifactor authentication (MFA) to add an extra layer of security. Be sure to remove inactive customer accounts, which could become entry points for hackers.
