Are you planning to conduct an SEO website audit but don't know where to start? 

Looking for a handy site audit checklist to help you evaluate how search engines view your site, and whether they can access, crawl, and index all of your web pages? 

A site audit is one of the most powerful activities an SEO can undertake to increase the user experience, generate higher search visibility, and more. 

A site audit is also one of the most difficult aspects of SEO. First, it's a major undertaking, requiring you to know what to analyze and how to draw conclusions from the data. Secondly, a website audit evaluates every aspect of the site's SEO and the user experience. It looks at content, technical SEO, links - external and internal links, particularly broken links - and more. 

That's why we created this checklist. It will help you plan and execute a successful SEO site audit for your brand. Before we get to it, though, let's cover some basics. 

Over the last couple of years, Google has made a variety of updates to its algorithm in terms of how they evaluate a site to show in their organic search engine results page (SERPs). Page speed, for example, is one of the more recent ranking factors including the AMP Project, which aims to improve the user experience for all users across different platforms. The more advanced Google's algorithms are to prioritize the experience for the user once they land on your site, site audits and audit reports become major necessities for businesses, resulting in half-year to yearly reviews of its website. Recently, Google has even re-upped its Lighthouse Chrome extension to improve its already vibrant features for SEO auditing, knowing how important this audit tool is for websites.


What is a Site Audit?

In simplest terms, a site audit is a process for evaluating the search engine friendliness of a website in multiple areas. Think of it as a thorough assessment of the site's overall performance. A site evaluation is based on whether or not a website appears on the SERPs.

Similar to auditing a business for following all the rules and regulations set out by the government, auditing your site must dot every “I” and cross every “T” to determine what issues need to be worked through for the website to rank, and rank well.

But website audits can be performed to see if there are areas for improvement within the site as well. This report card, of sorts, helps to identify a site that is clean and easy to operate compared to one that may have issues.


Elements of a Comprehensive Site Audit

A proper site audit will tell you what’s working on your current website, what’s falling short and how you can improve your site for the opportunity to rank.

Achieving all of the above requires auditing the site for six different elements:

  • Site health audit - This type of website audit assesses the architecture and usability of a website (oversees onsite and technical SEO, page speed, internal links, external links, and other factors, including meta descriptions, broken links, load time, page titles, and site structure). Many SEOs use Google Analytics to evaluate the overall usability of their site - this is a great place to start for your comprehensive audit of your site.
  • Site security audit -  It identifies vulnerabilities to security breaches. A security audit prevents compromising sensitive information of a business or its visitors.
  • Conversion rate optimization audit - This type of site audit helps businesses understand how visitors move through your website, what actions they take (filling out a form, purchase products or otherwise) and what is stopping the users from completing the end goals.
  • Google penalty and recovery audit - Identify penalties, which are either manual or algorithmic issues and assessed with a process to present solutions for site recovery. This audit can unveil issues with site speed or performance of mobile pages.
  • Competitor website audit – Knowing what your competitors are doing is one of the most important ways to stay ahead in your industry. By auditing your competitor’s website, you can find insights and opportunities to implement into your own digital marketing strategy.
  • Content and SEO audit – This type of audit can help you understand how content is performing on your site. Traffic to your web pages is impacted by content and SEO issues such as broken links, incorrect anchor text and duplicate content - just to name a few. These are common issues for many large enterprise websites and therefore, it is imperative to conduct a content audit or a technical SEO audit and produce authentic, engaging, and unique content with the right target keywords to the best of your abilities.


Why Do You Need a Site Audit?

It doesn't make sense, doesn't it? You've optimized the site to your best abilities, you've ensured technical compliance and covered all the bases of on-page SEO. 

Why audit the site, then? There are several reasons. 

To Keep Up With Changes in the Search Landscape

The changes to search engines over the years are vast on how search results are computed and how they perform. In the beginning, an individual would just include a keyword in the title and header tags, along with the content for the page. Gain and earn some some backlinks and see your website's SEO rankings and search visibility improve.

Today, everything has changed! Business owners and marketing leaders who have been marketing a product or service for a while have a hard time keeping up with the demands of SEO. Instead of a handful of factors a decade ago, there are now hundreds of search engine factors to consider.

Recent additions that factor into SEO include:

  • Content (on-page content, blog posts, video, titles, meta data, tags, etc.)
  • Responsiveness (mobile vs. desktop)
  • Page speed
  • Authority (how well and completely you cover the topic)
  • Technical code

To Optimize the Site Further

A typical website changes all the time too. New content gets added, older pages receive updates, the dev team updates server configurations and more. As a result, the website you've optimized originally, most likely, no longer exists, not in the same form, at least. 

Regular website audits allow you to spot and eliminate many new issues and errors, keeping the site optimized to the highest potential.

To Identify New SEO Opportunities

Often, auditing the site reveals many untapped SEO opportunities. During the process, you might discover under-performing pages to update, assets that should not be in the Google's index or technical tweaks to improve the overall user experience.

To Boost Conversions

An audit will help you re-evaluate how well the site is optimized for conversions too. Perhaps there are some opportunities to generate more leads or sales that you've missed before? Or maybe the strategies you've been using so far aren't as effective as you have thought? Analyzing the site will answer those, and many similar questions, leading to a potential for more conversions. 


How Do I Do an SEO Site Audit?

The simplest way to do a site audit is with an SEO audit tool. 

These tools crawl your site and identify broken and missing elements like broken links, meta tags, page load times, and more. Our platform, for example, examines 100+ areas that impact website performance.

If you Google "SEO site audit tool" and you'll see plenty of results for free SEO audit tools. Many of these tools are "lite" versions of the full, subscription tools offered by the provider. Larger enterprises may find these tools useful or they may need a more fully integrated SEO platform to reduce the time to make SEO a more scalable effort.

If you're planning on using a site audit tool, the audit process would look, more or less, like this:

Choose a Site Audit Tool to Crawl Your Site

This step is obvious, isn't it? Decide on which crawler you want to use to evaluate your website. There are many such tools on the market. At seoClarity, we offer our own website crawler, Clarity Audits.

  • Our site audit tool will crawl your HTML and JavaScript, much like Google's crawler does, and analyze them for over 100 technical health checks. 
  • Clarity Audits will also validate your schema, canonicals, hreflang tags, pagination and more.
  • It provides insights to optimize your site's architecture and improve the site's performance further. 

Run the Site Through the Audit Tool

This step involves setting up the crawler, and letting it do its job. It's that simple. 

Analyze and Act on the Audit Data

This is the most critical step. The site audit tool will deliver a plethora of insights. But they're only meaningful if you act on them. So, analyze all technical errors reported, and prioritize acting on them. 


But you may also want to conduct a manual website audit. In that case, we created a simple, easy-to-follow SEO audit checklist that delivers high results. We listed every audit check you should perform to drive the search performance forward. Simply click the button below and follow this guide to get started on your website SEO audit.



Sending the Site Audit Report

Here's a question I hear often - "How do I use the site audit report to show my company's executives the value of my work?"

Or, to put it differently, "How do I include the website audit results in my SEO report?"

It's a valid concern. Often, various stakeholders will demand a more detailed overview of your campaign's impact. In such a case, a simple rank or traffic report won't suffice. 

On the other hand, a site audit is most likely too complex a report to present to non-SEO personnel. 

So, what should you do?

My recommendation is to use the report in two ways:

1. Demonstrate your progress in improving the site's overall usability, while also explaining how the usability improvements affect the entire site's overall performance. 

2. Correlate your actions with eliminating technical or on-page elements with successes, be it rank increases, boost of ranking keywords, traffic, or other metrics. 

This way, you'll present the audit report in context for the person viewing it. Sure, they won't see the actual factors you've corrected, but at least they'll know how much working on the site's technical setup helps to achieve the company's goals. 

You can use various SEO tools to output the report. But also, your platform should allow you to do so with ease, and create reports covering everything you need to justify the SEO program. 

seoClarity's Reporting capabilities, for example, allow you to correlate all the efforts with the results, and demonstrate the value of your work.  



A website audit must become the priority once you've invested in building your entire website and the content. If you aren't seeing seeing the traffic results that are expected for your business from the organic results or if you've seen a decline in organic traffic, it's important that you invest in doing site audits to ensure there are not issues plaguing your site.

To have continued success with your technical SEO, completing an audit report helps check for errors and issues that can be addressed. An audit gets down to the root of the problems, so changes can be made to enhance the search visibility of your site. Learn more about how and what to prioritize in a site audit
