Note that certain themes manage the licensing and updates of the Knowledge Base plugin and will not require entry on this page.

Help Assistant

The Help Assistant (previously called Embed) is functionality lets you add your knowledge base anywhere on the current WordPress site or on any another site (the external site doesn’t need to be WordPress), the knowledge base will be displayed in a small dock in the bottom right hand corner of the site.

Clicking Show Snippet will display the HTML snippet that can be pasted in the footer of the target site.

Email Reports are weekly digests from your knowledge base sent directly to email addresses you specify. The reports include number of weekly review and average article feedback / rating. The overall top viewed and top rated articles is also listed. To received email reports, your site needs to be active.

The settings for email reports are contained in Knowledge Base > Settings > Email Reports.

Separate multiple recipients for the report with a comma. Enable HTML reports for the best readability.

As email reports is reliant on the ability of your site to send and deliver-ability of email, you need to ensure your site is active.

Knowledge Base Widgets

Heroic Knowledge Base comes with three widgets for displaying information from the Knowledge Base:

  • Articles – Knowledge Base Articles
  • Authors – Knowledge Base Authors
  • Categories – Knowledge Base Categories
  • Search – Search the Knowledge Base from any page
  • Table of Contents – Display a table of contents. Only works on knowledge base articles.
  • Exit Point – Capture visitors that leave your knowledge base to an internal/external system (see section below)

Widgets can be activated from Appearance > Widgets and dragging to an active widget area, this allows you to display key information from the Knowledge Base across your site.

Knowledge Base Widget Areas

There are widget areas, independent of the theme, controlled by the knowledge base:

  • Knowledge Base Sidebar (Home) – for the knowledge base homepage
  • Knowledge Base Sidebar (Categories and Tags) – displayed in knowledge base categories and tags
  • Knowledge Base Sidebar (Article) – displayed in knowledge base articles

How these are displayed can be controlled in the knowledge base sidebar options, detailed in the section above.


The most common use case for the knowledge base is a portal to deflect or assist support tickets or sales queries. When a visitor accesses the knowledge base but then goes on to raise a support ticket or complete a contact form (or access any other dedicated page) this can be tracked as a transfer. It works for both internal and external links. You just have to ensure the transfer widget is enabled.

Add transfer widget

From Appearance > Widgets, select the Knowledge Base Exit Point widget and drag it to an appropriate widget area.

A dummy page and widget will automatically be created when you first install the plugin.

You can set other options such as the title, text and button text.

Set the transfer page URL

The transfer page can be set from the widget’s link URL or from Settings>Transfer Options > Default Transfer URL. This should be the page you want to direct visitors to if they are unable to find an answer to their query in the knowledge base.

When a user clicks on the link in this widget, the source knowledge base location is recorded and can be analysed with the analytics module (see below).


The analytics module is available only in Heroic Knowledge Base (standalone) and KnowAll packaged theme, for the Plus and Pro tiers.

The analytics dashboard provides a way of analysing your knowledge base, helping you write better articles and fix issues where visitors are unable to get answers to their support queries.

The analytics data is populated by usage, so over time you can assess views, feedback and search behaviour.


The first tab is the dashboard, from where you can set the date range in the top right corner. This sets the period for analysis and will automatically be set to a month on login or after inactivity on the analytics pages.

From the dashboard you get certain key metrics for your knowledge base – views, key statistics (total articles, articles published and total views), article feedback and search effectiveness.

The knowledge base views is displayed as a graph, showing the total views on the knowledge base per month. This is drawn from visits on articles, categories and the knowledge base archive.

Next, the Knowledge Base statistics give an insight into the size and popularity of your knowledge base in the date range, displaying the overall total articles at the end of the period, the articles published in the period and the total article views in the period.

The article feedback shows the total helpful and unhelpful votes, giving an overall success metric for your articles.

The search effectiveness displays the total searches of the knowledge base in the period, and the number of those that failed- resulted in no results. This allows you to assess how well visitors are finding answers to their queries.


The feedback tab provides further insight into the visitor feedback on the knowledge base articles. Upvotes and downvotes (helpful/unhelpful) cast during the period are displayed on a bar chart.

Where visitors have then left feedback, the last 30 responses in the period are displayed below as cards. You can filter the cards by helpful or unhelpful votes and further interrogate the comments. Where comments are larger than the card, hovering over the comment will reveal the full text.

The search tab displays key knowledge base search information.

The search overview displays on a pie chart the split between searches that resulted in knowledge base articles being returned and searches where there were no results.

Searches by month in the period are displayed in a graph, allowing you to assess search volume trends over time.

Searches that results in no results are displayed in the null searches, sorted by the times no results are returned. If there are numerous null searches with the same words, it suggests visitors are unable to find the articles they are looking for.

The popular searches panel shows the most popular search topics visitors are looking for in your knowledge base. This information could be used to identify articles the should be improved or expanded to ensure they are catering for your audience.


Where you link to another resource (such as ticketing system, sales page or contact form) from your Knowledge Base, using the transfers functionality, a record is made of where this occurs to help you further identify articles or sections that need improvement.

By analysing where your visitors are leaving to raise a ticket, you get a metric of the transfer percentage and another indicator, in addition to visitor feedback.

Transfers can be added to three knowledge base objects – the archive, categories and articles. The transfer split pie chart gives the overall split of where transfers are occurring.

Category Transfers shows transfers made from categories, this could be when a visitor has navigated to a category but is unable to find an article that matches what they are looking for.

Article Transfers displays visitors exiting from an article, to help identify indivdual articles that need improvement.

F.A.Q. and Support

For customers with an active site, you can reach the support team at HeroThemes Support.

How do I reset article votes?

Votes for an individual article can be reset by editing an article, and checking the “Delete All Votes” box, found in the “Votes and Feedback” section. Then simply update the article and all votes will then be removed.

How do I password protect articles?

Individual articles can be password protected in the same way as other WordPress posts and pages. See Using Password Protection on the WordPress Codex for more details.

How do I integrate the knowledge base plugin with my theme?

Please see our separate Integrating Heroic Knowledge Base with your theme guide for detailed instructions on integrating the Heroic Knowledge Base with themes (standalone Heroic Knowledge Base purchase only)

I get a 404 error when accessing Knowledge Base pages?

The most common cause of this is the permalinks have not been flushed. To force this, simply visit the Permalinks settings page from Settings > Permalinks and hit save in your WordPress dashboard and then try again. It is recommended for most themes, the Permalinks are not set to default. For more details see this article for guidance on using Pretty Permalinks.
