We are privileged to live in an age overflowing with information. With access to the entire worldâs knowledge literally in our pockets, there is never an excuse to have dinner debates about whether Friendster was the worldâs first social network or how to the source of a Singlish phrase. Even more than the random useless trivia that we draw from the internet, we pretend the internet can substitute as as our parents, our legal advisors and even our clergy.
One major area of online search is health. We find a rash on our arm, we ask Siri to Google it. We even ask Google to diagnose multiple symptoms (bad idea: the results usually, falsely, point to a deathly disease).
To anyone that read the recent news about a person dying as a result of a Baidu search this is no surprise and we all do it. While Baidu might have quality issues when it comes to ranking results, the same wrong information is still available in Google.
Search as the means
According to a survey I conducted in the US onâŻSurveyMonkey AudienceâŻwith 395 random Americans, 77 percent of respondents admitted to going online to diagnose medical symptoms.
52 percent of Americans even used an image search engine like Google Images or Pinterest to diagnose a skin condition.
When respondents were asked why they went online instead of reaching out to to a doctor, nearly twice as many stated âease of useâ vs. cost.
While many medical professionals are opposed to this practice, there are others that think itâs aâŻgreat idea. According to these medical professionals, searching online for answers to health issues leads to a more engaged patient and even allows people to figure out if a ânasty rashâ is a mosquito bite or a creeping parasitic infection that requires a trip to the emergency room. Self-diagnosis might even be a good method to reduce the load on the health care system by empowering patients to triage themselves.
The source of all of this health info
However, there is one major issue with this hypothesis: Much of the medical resources on the web is horrifically inaccurate (just like everything else on the web). The authors of the vast trove of health information on the Internet are not trained medical professionals. Rather, they are âcontent marketersâ hired to produce articles to rank high on Google searches. That means that much of Googleâs highest ranked medical advice is written by a person whoâs job is to simply bring people to a website.
Lacking the medical background to write original medical information, content marketers source their writing from other websites. For the discerning content marketer trained to ignore user generated content, they instead source content written by other content marketers thus contributing to the ever growing cycle of manufactured, and often false, medical advice.
âThere are ample examples of how doctors who have taken an oath to âdo no harmâ respond to financial and other incentives in ways that do harm patients,â says Josh Steimle, CEO of digital marketing agency MWI, citing aâŻ2015 Los Angeles TimesâŻarticle that explores variances in the rates of c-section births in Los Angeles area hospitals.
âI have great respect for content marketers and doctors, but should I believe that content marketers, who havenât taken anything like the Hippocratic Oath, and arenât nearly as sensitive to the harm they may be doing, are producing accurate health information online when it may not be in their best financial interests? Itâs great for patients to do research online, and there is valuable work content marketers can do to put helpful medical information on the internet. But since we canât even trust doctors 100 percent of the time, itâs up to patients to do thorough research and make sure the information theyâre getting is accurate.â
To a patient in need, it is not obvious that the health care information found online was not produced by a medical professional. The medical advice usually appears on seemingly reputable health websites or even homepages of local family doctors. Additionally, consumers are lulled into thinking the information must be correct because it appears high on Google. Nothing could be further from the truth.
âDepending on the scenario, relying on inaccurate medical information could have deadly consequences when wrong advice is given,â says marketing visionary John Rampton. âWhile there are certainly laws and codes of ethics that require content produced online to be correct, content marketers might not even be aware that these laws even exist.â
Example
To illustrate the scale of this issue, letâs look at a very standard Google query like âcure nearsightedness.â Most eye care professionals would say that there is no way to revert nearsightedness. However, if a layperson searches such a question online, they would be led to believe that indeed, nearsightedness is curable. Without linking to any particular results (I donât want to send people to these pages), there are particular websites that offer unproven and false ways to âcureâ nearsightedness. Consumers may not be aware that the motivation behind these websites is to sell a product rather than share information.
In this case, the harm is the false hope of an eventual cure, but the risk is far greater when it comes to advice about âeating salad to stave off cancerâ or following diets that deprive the body of essential nutrients.
Google as the savior
Itâs worth it to note that all is not lost in the fight against this tide of unverified and bogus content. In the beginning of 2015, Google started showing medical information in the knowledge graph. While, Google uses an actual doctor to verify these answers, these verified results will likely only show up on the limited amount of queries for which Google is able to curate the results.
On the millions of other queries that could not possibly be moderated by a human, Google relies on the standard components of their algorithm which are designed to evaluate quality and relevancy. Without knowing exactly how Google makes these determinations, we can assume that Google looks at which websites link into a piece of content as a signal of quality. Additionally, Google could analyze article wording and phrasing to see if it is similar to other trusted medical sources.
Health search in the new norm
One in 20 searches conducted on GoogleâŻare for health related queries; therefore, the trend of using Google in lieu of a doctor is likely to grow. This challenge of keeping us protected from bad advice is set to become even more critical as more users turn to the internet for daily questions. In my survey, the majority of users only looked at 1-2 websites for medical advice, so provided Google can keep these top results accurate, they limit the exposure to factually inaccurate results.
If you are questioning why people even bother creating content that Google will keep out of the top results, you are not alone. Thatâs an answer for another article. In the meantime, you can rest assured that the runny nose you have is probably not the Zika virus. But just in case you are concerned, here are the actual symptoms of Zika on Google as approved by a doctor.
