What Is a Content Audit? How to Run an SEO Content Audit

Quick summary: A content audit is a review of all the content on a website to optimize its quality and SEO performance.

Content audit is a review of all the content on a website to optimize its quality and SEO performance. When done with the right technique, your articles get better, which helps lift rankings and improve user experience, and in turn grows traffic sustainably. So what exactly is a content audit? How do you audit content the right way? For everyone asking, this article from MONA Media gives a detailed guide to checking your content as effectively as possible.

What is a Content Audit?

What a Content Audit is

A content audit is the process of reviewing all the content that exists on your website to decide which content needs updating, redirecting, merging or removing. This lifts the quality of your SEO content and improves user experience, and makes it more likely they rank high on Google.

Benefits of auditing content for SEO

For websites that have been running for 6 months or more, or that have a lot of content, a regular SEO content audit is a must, because it brings the following benefits:

  • See how each article really performs, from traffic and bounce rate to the keywords it ranks for. 
  • Spot articles with no traffic, no Google top rankings, or outdated content that no longer has value.
  • Identify promising articles that can be optimized further to rank higher and gain traffic.
  • Find content that matches users' search intent. 
  • Build a solid foundation for rolling out SEO strategy over the long term.
  • Control the SEO-standard articles on your website more easily. 

When do you need an SEO content audit?

You don't need to run a website content audit every week, but you shouldn't wait 2 to 3 years before checking old content on your site either. Based on MONA's experience, you should run an SEO content audit when you see these signs:

Running an SEO audit for thin content

Auditing content for thin content

Thin Content means short, sketchy articles that give users no real value. Google's algorithm rates this kind of content very low, and your site can slide down the rankings with no brakes. 

While running a content audit, you can easily spot thin content by these traits:

  • Very short content with no depth, but lots of backlinks pointing to it.
  • Superficial information that offers no clear value.
  • A messy layout or one “stuffed” with too many affiliate links.

A common example is product review pages. Instead of giving an in-depth view, the article just lists specifications or basic usage. The rest is filled with affiliate links, so readers lose interest quickly and leave.

Low-quality, outdated content

After a while, every website ends up with some low-quality or outdated content. That is when you need to start SEO audit to refresh the content and improve its chance of ranking on Google. Low-quality content usually shows these signs:

  • No traffic, or extremely low traffic, for more than 4 months.
  • No keyword in the top 100 on Google.
  • Targets the wrong keyword and doesn't match what users need.
  • Competes with your own other articles, “cannibalizing” them (keyword cannibalization).
  • Weak SEO on headings, messy presentation, and doesn't match search intent.

Duplicate content

Auditing duplicate content

Duplicate content (duplicate content) is one of the most common problems, yet it is often overlooked during an SEO content audit. If you don't find and fix it early, Google may rate your website lower and your search rankings can suffer. These are the signs that an article has a duplicate content problem:

  • The site has many articles that repeat the same ideas or wording and differ only in the title (internal duplicate content).
  • Content copied from another source with no edits (external duplicate content).
  • Too many ads that overwhelm the main content.
  • Articles that aren't 100% copied but are 70 to 80% the same, which kills their uniqueness.
  • Pages with no original content, where the main area is empty and only the menu, footer or sidebar shows.

Irrelevant content

For a site to really deliver results and conversions, the business needs its core content to make up 75% of the whole site, and supporting content 20%. If your website is off this ratio, or has too many articles on unrelated topics, it is time for a web content audit. Signs of irrelevant content include:

  • Rambling into topics outside the products/services you offer.
  • Too much supporting or trending content, with not enough core content.
  • Articles that bring no clear value to the business or the reader.

Auditing high-traffic content

Articles with high traffic still need a regular content audit to hold their rankings and keep performing. Even if they are attracting readers now, competitors can overtake them if they are not updated. Also, some articles get lots of visits but have a high bounce rate, which shows a poor experience. Running a website content audit in this case helps you improve article quality, keep users on the page longer and get the most out of the content you already have.

11 ways to run a thorough SEO content audit for your website

Are you wondering how to audit content to improve rankings and user experience? With experience from hundreds of real SEO projects, Google SEO companies MONA will share 11 ways to run a thorough web content audit that helps your website grow steadily on Google, in the sections below:

Run an SEO content audit through keyword research

Before you evaluate content or start a content audit process, you need to check whether the article targets the keyword users actually search for. Use keyword research tools like Google Keyword Planner, Spineditor or Google Trends to analyze competition, difficulty, long-tail keywords and the latest search trends in your field.

Keyword research before an SEO content audit

Example: If you want to audit the content of an article about “SEO guide”, type the keyword into Google Search and look at the suggested suffixes such as SEO keyword, youtube, website, Google Map. 

From these results, check the keyword's search volume to see what content users care about, then choose a fitting direction to optimize. You should also analyze the top-ranking articles to see how competitors structure their content. This helps you plan outline content that follows SEO standards, performs well and stays close to user intent.

Optimize keywords in the article

From MONA's SEO content writing services from MONA, you shouldn't stuff or force repeat keywords. Spread them sensibly across these strategic positions:

  • Main title, Heading 1 and URL.
  • Meta description.
  • Opening paragraph (intro).
  • Subheadings (H2, H3).
  • The first paragraph of each section.
  • Image alt text and captions.
  • The conclusion.

Optimize content quality

Optimize content to be high-quality and valuable to readers

Quality content today is not measured by length. It comes down to accuracy, expertise and the real value it gives readers. Copied, outdated, rambling or off-topic articles have almost no chance of ranking on Google.

To avoid this when auditing content, focus on refreshing it by:

  • Optimizing the audited content with original, creative material that is more valuable than your competitors'. You can add figures or evidence to make the article more credible.
  • For knowledge-sharing articles, make sure the information is accurate and up to date. For service articles, analyze the problem clearly and present the best solution for the customer.
  • Add a CTA that invites customers to buy or try the product/service.

Use Schema to optimize the content audit

Schema doesn't directly push keyword rankings, but it is a “powerful helper” in the SEO content audit and in improving how you appear in search results. With Schema types like star ratings, FAQ, breadcrumbs or multiple-answer posts, your site stands out more and takes up more space on the SERP, which attracts users at first glance.

When your content looks livelier and clearer than your competitors', the click-through rate (CTR) rises noticeably. It is a simple but effective way to improve overall SEO performance that many people overlook.

Optimize the meta description

Optimize meta tags for the content audit

Meta description is the short summary under the title in search results, and it persuades users to click through and read the full article. To get the most from the description, make sure that you:

  • Keep the meta description short, around 100 to 150 characters, yet complete and appealing.
  • Include the main keyword so Google understands the content.
  • Summarize the article's key points and hit the searcher's insight.
  • Give each article its own meta description, and avoid duplicates that hurt your SEO score.

Reorganize heading tags more sensibly

To help readers and Googlebot understand your message, use headings to present main ideas clearly and keep a logical order from H1 to H4. Each heading should contain the main or a secondary keyword, but don't overstuff it, or it reads unnaturally and annoys customers. SEOers also shouldn't use hidden text for the H1 when optimizing a content audit, because Google may think your website is manipulating the algorithm.

Optimize internal links in the SEO content 

Insert fitting internal links when optimizing the web content audit

If you want to improve search rankings sustainably, you can't skip internal links in the SEO content audit. Instead of stuffing links into every article, choose related articles with a fitting context and link from them to the page you want to rank. 

*Note: An article that already has high traffic shouldn't carry too many internal links, because they easily scatter the user experience.

Optimize image ALT text

Optimizing the Alt tag for images is also an effective way to audit content for SEO. Based on experience running SEO services at MONA, during a content audit you should avoid these image optimization mistakes:

  • Using images copied from the internet or protected by copyright.
  • Low-quality, blurry images.
  • Illustrations unrelated to the article's content.
  • Missing ALT tags, so Google can't understand what the image shows.
  • Unclear image file names with no keyword.
  • Image sizes that don't fit the website layout.

Check the outline of the content you audit

Optimizing the outline is also an important step in a content audit

No matter how smooth and persuasive the wording is, an article without a clear structure and with a cluttered layout still struggles to hold readers. This directly affects key metrics like bounce rate and time on page. So before you start writing, spend time studying the bounce rate and time on site of old articles to see which ones are underperforming. From there, you can build an SEO-friendly, well-organized outline that helps both readers and Google reach the main information easily.

Optimize the website structure

During the SEO content audit, review your site's content navigation to set the priority order for rolling out keywords. You can also use internal links and anchor text naturally to strengthen the connection between articles. If you don't have a specific direction yet, look at the Silo structure, a technical SEO technique that groups articles by related topic, which is easier to manage and boosts semantic linking across the whole site.

Analyze how competitors build their content

During a content audit, also take time to watch your competitors, especially those ranking high for the same keyword set as you. This helps you see which opportunities you missed and where you can overtake them. Based on MONA's experience, start by:

  • Searching your main keywords and identifying the sites in the top results.
  • Comparing the strengths and weaknesses of their content with yours.
  • Analyzing who they target, and whether they follow any trend or standout strategy.
  • Observing how they lay out their content and structure their website.

From this analysis you will have more data to optimize content effectively and build a stronger long-term strategy.
