Learn how TikTok, Instagram, and YouTube algorithms rank search results and how pharma marketing teams can make their content appear first for patients.
Patients now search on TikTok, Instagram, and YouTube the way they once searched on Google. Each platform uses an algorithm to decide which posts appear first. Brands that understand how those algorithms work get found. Brands that do not stay invisible.
Most brand content is planned for the feed, where the goal is to be seen by followers in the first day or two. Search works differently. The algorithm is not asking who follows the brand. It is asking which post best answers what this person just typed.
That shift matters because it means a large following does not guarantee a top position. A small account with one clear, well-structured answer can outrank a big brand page on the exact question a patient is asking, again and again, for months.
Platforms do not publish every detail of how they rank content, but what they have shared points to the same core signals. They fall into two groups: what the post says, and how people react once they find it.
The first group is relevance. The algorithm reads the words in and around the post to decide which searches it answers. If the patient's search words appear clearly, the post is matched to the search. If they appear only in hashtags or not at all, the match is weaker.
The second group is behavior. After someone finds a post through search, the algorithm watches what happens next. Did they watch to the end, save it, share it, or visit the profile? Posts that satisfy searchers keep rising. Posts that people leave in the first seconds slowly drop down the results.
Health is one of the categories platforms treat most carefully. Many of them apply stricter rules to medical content and give more visibility to sources they consider credible, such as healthcare organizations and qualified professionals.
For a pharma or healthcare brand, this is an advantage that often goes unused. Clear sourcing, accurate information, and a consistent, recognizable account help the algorithm trust the content. Exaggerated claims or unclear sources do the opposite, even when the post is well designed.
Keywords are the link between a patient's question and a brand's answer. But the right keywords do not come from the brand plan. They come from studying how patients actually search, which is often very different from how the brand describes the condition.
A brand plan is written in clinical language: hypertension, dyslipidemia, and reflux. Patients type what they feel, in their own dialect, often as full questions: "Why do I feel dizzy in the morning?" or "My chest burns after eating." They mix Arabic and English, misspell medical terms, and search on behalf of family members.
Studying search behavior means collecting those real phrases before writing anything. Platform search suggestions, related searches, comments, and questions under competitor posts all show the words patients use. And because those words change with news, trends, and seasons, the list needs regular review, not a one-time exercise.
Once the right keywords are known, placement decides whether the algorithm can read them. Hashtags alone are not enough. The same keyword in the places the algorithm reads first gives the post a real chance to rank.
Then check the results. Search your top three patient questions on each platform, see who ranks first, and compare saves and shares to likes. In our work across the region we consistently see strong medical content held back by weak signals: the right answer, written in the brand's words instead of the patient's, placed where the algorithm cannot read it.
Ranking first in social search means working with the algorithm from the start of the brief, not fixing posts after they are published. Kepler builds each of these signals into the content, so it is made to be found as well as seen.
Which keywords should the content be built around? Kepler's Social Media Advanced Listening studies patient search behavior inside each platform and finds the exact phrases patients type, so every post matches real searches. Medical Content Creation then places those phrases in the first line, caption, and on-screen text, while keeping the science accurate and clearly sourced.
How does the content hold attention once it is found? Kepler's medical copywriting turns each keyword into an opening line that stops the scroll without stretching the science. Video Production and Motion Graphics then answers the question in the first seconds, which keeps searchers watching and raises the post in the results.
How does a new post build its first signals? Paid & Performance Media gives key content an early push to the right audience, creating the watch time, saves, and shares that help it climb the results. Social Media Management keeps the account consistent and credible and tracks search performance in every report.
The algorithm doesn't rank the biggest brand. It ranks the clearest answer.
