KnowAll is part of the HeroThemes family - themes and plugins that power documentation and support for businesses worldwide.

“At Pagely we set up the HeroThemes the KnowAll theme as a pre-sales KB for people evaluating our managed WP hosting service. Initially we had intended to run this as an internal-facing tool to be used exclusively by our sales team. The idea was to make the KB into the authoritative hub for all pre-sales questions. Training would consist of having new salespeople self-educate about our service by combing through KB articles then listening to recent calls, reading sales exchanges and internal chats and then updating that info in the KB. Midway through this process of setting this up we realized with extra work we could externalize the resource and transform it into a self-serve resource that could be used by prospects as well as salespeople. We put our interns on the task of extracting & sanitizing Q&A from the aforementioned channels. To date have over 400 discreet question & answer pairs from past sales exchanges. We added a livechat widget to the KB site for leadgen and as a mechanism to answer questions not currently addressed by the KB. In all the KB has been a great asset to the Pagely sales process. The type-ahead search feature provides a fast way to filter by keyword and the categorical organization gives a simple means to browse by topic area. Backend reports show us which articles are unclear and need refinement. Having it indexed by Google gives us long-tail SEO benefits. And most importantly we now have a scaleable way to onboard our new salespeople. The KB allows us to preserve tribal sales knowledge and exposes it in a way that teaches salespeople and also accommodates prospects who prefer to get their answers self-serve. We're happy customers of HeroThemes and endorse both the product and the support we've seen from the company.”

“The KnowAll Knowledge Base theme gave us an out of the box solution to spin up a full featured and well designed support center for our users. We love the ease of setup, SEO features and analytics tracking.”
SB Simon Burns
“I love it. It gives you everything you need for your knowledge base without any hassle. Setting it up is very easy and I love the sidebar function that automatically creates a navigation.”
FV Floris van Vredendaal
“I'd looked at, and even paid for and tried out, different help desk templates for WordPress before deciding on KnowAll. One of the key things that made me use KnowAll was the professional appearance the template instantly gave my website without the need for me to alter the design or get custom header graphics created. I also really liked the built-in search and the automatic inclusion of related links at the bottom of help posts. After installing and using KnowAll for a while I've really come to appreciate the analytics pages. The analytics pages let me know what people are searching for giving me valuable clues as to which help topics I might add as well as easily presenting feedback from my users on which topics helped them or could be improved. KnowAll is well worth the money.”
ML Michael Lawrence
