AI - Super Hearing for Healthcare Marketers
Gartner reports that artificial intelligence (AI)-driven applications play an essential role in 5 of the top 10 strategic predictions for 2018 and beyond.1 Even though AI is a dominant topic in business discussions across industries, results from a recent survey imply that many marketers feel ambivalent about the effectiveness and practicality of AI.2 The Arteric team created this slide presentation and supporting commentary to provide marketers with practical examples that may help them make wise choices about whether to apply AI, and if so, how. The examples illustrate how AI accelerates identification and validation of critical market insights. You’ll also learn what actions to take today to succeed in a future driven by AI, natural language processing, and voice interfaces.
If you have questions about the presentation or how to determine if AI would enhance your campaigns, the Arteric team is happy to answer them. You can reach us at 201.558.7929.
Signals. Patterns. Insights.
[Slides 1-4] AI’s ability to evaluate multiple variables within massive volumes of marketing data enable this technology to detect weak behavioral signals that evade human analysis. AI’s processing power then extracts patterns of audience needs and behaviors that analysts convert into insights to guide brand strategy.
Marketers aren’t alone in leveraging AI’s signal detection and pattern-recognition skill. Stanford University researchers use AI’s signal-detection and pattern-recognition skill to eliminate variability when interpreting X-rays to diagnose pneumonia. After 1 month of optimization, Stanford’s CheXNet diagnosis algorithm was identifying pneumonia with greater accuracy than individual radiologists.3
Voice Search Increases the Complexity of SEO and SEM Campaigns
Search is Moving to Voice
[Slides 5-7] In our examples, AI’s utility revolves around signal detection and pattern recognition. To appreciate why AI is so frequently discussed as a marketing tool, we have to discuss the technology in the context of the rapid changes underway in online search. Voice-driven search is replacing keyboard-entered search. Gartner predicts that by 2020, 30% of all Web browsing sessions will be done without a screen or a keyboard.4 Advances in voice recognition technology and the ubiquitous presence of smartphones — 1.84 billion units predicted to be shipped worldwide in 2020 — are fueling this paradigm shift.5
Healthcare professionals (HCPs) and consumers aren’t waiting for 2020. Almost 1 in 4 healthcare professionals (23%) are currently using a voice assistant for professional reasons. Of this 23%, more than three quarters (78%) use search for critical information on treatments, dosing, diagnoses, disease, and other clinical information.6 Consumers are also migrating to voice search. Twenty percent of all mobile queries are made by voice.7
Ranking at Position Zero Replaces Ranking on Page 1
[Slides 8-10] Voice-driven searches produce 1 spoken search winner, not 10. This winning search position is called position zero. Currently, voice commands to scroll through a list of audible search responses that follow position zero don’t exist. Combine this with Gartner’s prediction that by 2020, 30% of searches will utilize screenless devices, and marketers face an imminent future where being the featured search response will be essential to getting their content heard.4
Brands have an additional incentive to ensure that their content is featured at position zero. Recent research indicates that 2.6% of Google’s rich-snippet search answers are incorrect or irrelevant. Ensuring that brand content isn’t superseded by imperfect third-party information is a key challenge that brands face.8
Natural Language Inquiries Dominate
Google reported in 2016 that 70% of all voice searches entered into Google Assistant were expressed as natural-language questions.9 Natural language, or conversational language, is how people speak with other people. “How much aspirin should I take?” is an example of a natural-language voice search. Typing the keywords “aspirin” and “dosage” into a Google search window is the antithesis of natural conversation.
Natural-language inquiries require search analysts to extract context and intent, not just keywords, from marketing data. In addition, people can ask the same question in many different ways. Both characteristics increase the volume and complexity of data processing required for search analysts to extract insights from marketing data (eg, pay-per-click data and analytics data from the Google Search Console tool).
This increase in data volume and complexity encounters the limits of human-based data analysis quickly, making it impractical to scale personalized content and experiences.
AI Accelerates Identification and Validation of Market Insights
[Slide 11] Arteric’s objective is to position our clients for success today and 18 months down the road. To accomplish this, we pay close attention to what Google is saying. Google has stated that it may give priority in the search results to content that is relevant and authoritative and that answers a question or enables the searcher to complete a task. Arteric analysts scour brand marketing data to find insights that enable brands to create content that satisfies these factors.
Insight Discovery Without AI
[Slides 12-15] To assess the effectiveness of a brand’s content strategy, Arteric analysts evaluated data from 55,000 online searches. We identified 1,700 brand-related questions, of which 235 were appropriate to be addressed by the brand’s content. We performed deep search engine result page (SERP) analysis by evaluating 175 of these questions to determine if Google served up brand content that answered the user’s question. The results — brand content appeared in the search results 110 times but answered only 4 questions with relevant, authoritative content.
It took 80 hours of analyst research to identify this huge customer experience gap.
Being software engineers as well as healthcare strategists, we’re always asking ourselves if there’s a technology solution that would enable us to work smarter and faster. Arteric analysts are as good as they come, but humans have limitations when it comes to data analysis. It’s challenging to cost-effectively analyze much more than 50,000 to 60,000 data points. And there are only so many variables within the data that humans can simultaneously evaluate.
These issues limit humans’ ability to detect trends, especially when signals are weak and scattered. We sought a technology to overcome these limitations. This brought us to AI.
Artificial Intelligence Fundamentals
[Slides 16-19] Before describing how we applied AI to address a comparable business problem, it’s important to introduce a few fundamental concepts.
AI is not an out-of-the-box solution. Each solution must be optimized according to the needs of the business problem to be solved.
AI is a collection of many algorithms. Natural language processing, which enables AI to understand the meaning and context of human language, and machine learning, which allows the AI solution to self-improve, are frequently mentioned approaches. But there are many capabilities to consider when evaluating an AI solution.
AI Has 3 Functional Components
Data: Brand marketing data are the most essential component of an AI solution. The data contain hidden market insights, but the data are also used to “teach” the AI algorithm how to perform the analysis that uncovers the insights. Pay-per-click and Search Console data, social media feedback, customer service transcripts, and any form of data that discuss the brand must be digitized and warehoused under the brand’s control. The brand must be in full control of the data. If you’re not warehousing all your marketing data, start today.
Technology: AI technology has two functional components. The analytical “engine” provides the functionality that evaluates the marketing data. Many commercial AI engines are available, but it’s essential to select the engine with the capabilities that best align with the business problem that the analysis must solve. Brands are best served when they work with a vendor who can accurately analyze the brand’s business problem, narrow it to a solvable problem, and recommend candidate algorithms.
The second technology component is an interface that uploads the marketing data into the engine. The interface is custom developed and reflects the nature and structure of the data.
Strategy: Selecting the appropriate engine is the first strategic decision. Next, the engine must be taught how to analyze the data and must be given appropriate training data. If the business problem involves common knowledge (eg, which color of car do women prefer?), Wikipedia would provide appropriate training data. If the analysis requires disease-specific content, medical journals would be used to train the engine.
The machine-learning capabilities of AI require a separate training strategy. Machine learning occurs through a network of algorithms. Machine-learning strategy involves selecting the algorithms that are most appropriate for the business problem and then testing and optimizing the network with training data and validation data sets.10
Insight Discovery with AI
[Slides 20-23] Zicam® is a leading developer of homeopathic OTC remedies for colds and cold-related ailments. Through human data analysis, Arteric helped the brand reach its sales goals one month early. We then searched for ways to improve on these results. Based on the available pay-per-click and Search Console data, the strategy we selected would require analyzing a minimum of 250,000 data points. This would require at least 300 hours of human data analysis.
This inspired us to develop an AI solution. Guided by the specifics of the business problem that had to be solved, we evaluated numerous vendors and selected the Retina AI engine from Cortical IO. Arteric’s development team created the interface that uploaded data into the engine.
We applied the AI solution to uncover how audiences in the United States were inquiring about cost and other issues related to Zicam®. We analyzed 250,000 searches in 2.5 minutes, a nice speed boost compared with the 80 hours required to evaluate 55,000 data points in the past.
Freedom to Experiment
The dramatic processing speed made it practical to further analyze the Zicam marketing data. Just for fun, we tasked the AI solution to identify the OPPOSITE of cost and the other issues that the AI solution initially evaluated. To our surprise, we uncovered a handful of foreign-language inquiries in this English-only campaign that ran solely in the United States.
Intrigued by the unexpected data, we integrated the AI solution with algorithms that translated data and classified the data.
The surprise grew. The multilingual algorithm identified 147 foreign-language inquiries, nearly all relevant to the brand. We shared this with the client. The AI data corroborated client data that were generated independently. As a result, the client is considering multiple new strategies to address the market.
Recommendations for Healthcare Marketers
Curiosity: The Fourth Component of AI
[Slides 24-26] Data contain the value that technology and strategy unlock. But the key that fits the lock is human curiosity and the desire to look beyond the obvious. It’s undeniable that AI requires exceptional technical and analytical expertise. But explorative, playful thinking that reimagines what we might find if we look past the obvious is also essential.
Data Are Your Intellectual Property. Treat It Accordingly.
Data provide the fuel that powers AI. Even if you don’t plan to utilize AI in the near future, it’s essential to collect any and all marketing data and warehouse them. Ideally, the data should be well organized and highly structured; but if nothing else, take action to ensure that your brand is gathering and securely storing every byte of marketing data.
Narrowly Define the Business Problem
Current AI algorithms solve narrowly defined business problems. Broad problems that are loosely defined won’t be solved by today’s AI and machine-learning solutions. The technology and the data required to solve broad problems are not feasible for healthcare marketers.
It Takes a Team
Multiple talents are needed to develop, apply, and optimize an AI solution. Brand business owners and strategists, data experts, software developers, and a visionary strategist to connect the dots comprise a complete team. The common thread that binds the team is that every participant — internal or external service provider — must have expert-level familiarity with the nuances and intricacies of the business problem that the AI solution must solve.
Continue the AI Conversation
