Find the topics, questions, and trends your audience cares about before you start writing.
Content research can mean several different things: measuring search demand, finding popular articles, spotting emerging trends, understanding an audience's media habits or collecting the questions people ask. Those signals answer different planning questions, so the best research stack often combines more than one.

For search-demand research
#1 of 7 in Content Research
Semrush is useful when content research begins with what people search for and which competing domains already receive visibility. Keyword Magic Tool can expand topics into related queries, while competitor and gap reports show terms associated with rival sites; this helps teams estimate demand and understand which parts of a topic already have active search competition.
For audience behavior research
#2 of 7 in Content Research
SparkToro examines audience behavior to inform content research, with a different focus from keyword volume. It can show which websites, social accounts, podcasts and other sources a defined audience pays attention to. That helps teams understand where an audience gathers and which creators or publications shape its information environment before deciding what content and distribution approach to use.
For early trend detection
#3 of 7 in Content Research
Exploding Topics tracks subjects showing sustained growth and organizes them into browsable categories and trend histories. The workflow is useful when content planners want to identify emerging technologies, products or consumer interests before keyword research tools show mature demand. It works best as an early-warning source that points researchers toward topics needing deeper validation.
High-engagement examples
#4 of 7 in Content Research
BuzzSumo helps researchers discover widely shared or discussed content and monitor media activity around topics. The result is useful for studying headline angles, formats and publications that already earn attention. It can also help identify journalists or creators around a subject, linking editorial research with outreach and distribution planning.
Question and phrase discovery
#6 of 7 in Content Research
AnswerThePublic organizes search-related phrases and questions around a seed topic, making it useful for discovering the wording people use when exploring a subject. Writers can use those patterns to identify FAQ ideas, subtopics and long-tail angles that a broad keyword list may hide. It is particularly effective near the beginning of a briefing process.

It depends on the goal. Search-led programs often start with keyword demand, while thought leadership and distribution-led programs may begin with audience behavior and publications. Using both gives a fuller view of what people look for and where they already spend attention.
Keyword tools measure established search behavior and competitive results. Trend tools are designed to surface movement over time, including subjects that may still have limited search history. A trend can be early and promising even when traditional keyword metrics are not yet mature.
