When monitoring a website, ContentKing also audits all pages on the website for SEO issues and reports them to you. Thanks to our 24/7 monitoring you always have real-time data about all issues of your website at your disposal.

How ContentKing reports issues

The issues in ContentKing can be viewed on multiple levels:

  • Issues detected on specific pages
  • Issues detected on the platform level (domain, XML sitemap, and robots.txt)
  • Issues detected across the entire website

Issues on the page level

If you are interested in issues that ContentKing detects on a specific page, go to the page detail screen.

On the right side of the screen, you will see all open issues on the page together with their impact on the page’s Health score:

Issues on the platform level

The Platform section in ContentKing contains data about the technical platform of your website, which consists of three parts:

  • Domain
  • XML sitemaps
  • Robots.txt

On the right side of the screen, you can see the issues that ContentKing is detecting in relation with the technical platform.

Issues on the website level

You can always find a real-time overview of all issues that ContentKing is detecting on your website in the Issues section.

By default, you will see all issues reported for the whole website, but you can also filter the issues by status or by segment.

On the left side of the screen are the issue categories. When you click on one of the issue categories, you will see a breakdown of the individual issues within the category together with more details about each issue such as how many pages are affected.

If you want to know exactly which pages are affected by a certain issue, click the See affected pages button and you will get to a screen with all the affected pages, where you can use filters to zoom in further.

Apart from the issue categories, the Issues screen also contains two charts: Health per segment and Affected pages per category.

Health per segment

The Health per segment chart shows the Health score of each segment of your website. This can help you quickly determine which parts of the website are in the worst condition and should be prioritized for optimization.

For example, if you have a segment for the most important pages on the website, you can easily check how the segment is doing in terms of the Health score and take action if necessary.

Affected pages per category

The Affected pages per category chart shows how many percent of your website’s pages are affected by the different issue categories, so you can easily spot the widest-spread issues of the website. You can also use the Segments filter to view the chart for a specific segment.

Issue states

An issue in ContentKing can be:

  • Open
  • Closed
  • Ignored
  • Still unknown
  • Not required
  • Not applicable

If an issue is open on the page level, it means that the page is affected by the issue.

If an issue is open on the website level, it means that at least one page is affected by the issue.

The open issues are marked by a red exclamation mark icon.

If an issue is closed on the page level, it means that the page is not affected by the issue and no action is needed.

If an issue is closed on the website level, it means that no pages on the website are affected by the issue.

The closed issues are marked by a green tick icon.

If an issue is ignored, it means that ContentKing is not evaluating the issue and you are awarded the Health score points as if the issue was closed.

Ignored issues are marked by a grey ban icon.

Still unknown

If an issue is still unknown, it means that ContentKing hasn’t yet finished the initial evaluation of the issue.

Still unknown issues are marked by a grey hourglass icon:

Not required

When an issue is not required, it means that ContentKing is only evaluating the issue on a specific part of a website (e.g. indexable pages). You can control this using Issue configuration.

Not applicable

When an issue is not applicable, it means that it’s not possible to evaluate it on a certain URL due to its nature. For example, page title length cannot be evaluated on pages where the page title is missing completely, or on redirected URLs which don’t have a page title by nature.

Built-in reference material

Whenever you’re not sure why ContentKing reports a certain issue, just look under the issue where you will find an explanation of why the issue is being reported.

If you want to know more, you can click the Learn why button which will provide you with additional information about the issue as well as with a link to an in-depth article on that topic in our Academy.

Issues and the Health score

The Health score in ContentKing is a metric to determine the degree to which a page, or a website overall, is optimized for SEO.

Same as with the issues, there are also three levels of the Health score that you can view:

  • The Page Health which can be viewed for each page on the page detail screen
  • The Platform Health which can be viewed in the Platform section
  • The Website Health which can be viewed in the Issues section

The maximum possible value of the Health score is 1,000 points and it is influenced by the Issues. Each issue is valued with a certain number of Health score points based on the impact it has on the SEO performance.

The Issues are always ordered by their impact on the Health score, which is represented by the number of Health score points on the right side of the issue category tab.

The impact of an issue on the Website Health is based on the number of affected pages as well as on the Importance of the pages. This means that issues on important pages have a bigger impact on the Health score than issues on less important pages.

This helps you quickly discover the most pressing SEO issues of your website and prioritize your efforts in resolving them.

When hovering over or clicking on an issue category tab, the potential improvement of the Health score in case of resolving all issues in the category is marked with blue color on the Health score bar:

Customization of the auditing suite

ContentKing allows you to tailor the auditing suite to your specific needs to make sure you have the right insights for your team or your clients.

Issue ignoring

The issues for which ContentKing is auditing your website are based on SEO best practices and are universally valid for any website and any market.

However, it can happen that some of the reported issues or issue categories are not important or relevant for you.

For example, if your audience is not using Twitter and you are not focusing on this social media channel, you might not want ContentKing to report the Twitter Cards issues for your website.

In such cases you have the option to ignore an issue or a whole issue category. By doing that, ContentKing will stop actively reporting the issue and you will be awarded the Health score points as if the issue was closed.

Issue Configuration

ContentKing’s auditing suite comes with default test parameters for each issue, which are based on industry surveys and best practices within SEO, and are therefore universally valid.

However, you can also adjust these test parameters to your specific needs.

For example, Google enforces different meta description lengths in different markets, so if your website focuses on a specific market, you can change the length parameters which ContentKing uses to assess the meta description length.
