What is Google Trends?
Google Trends shows what the world is searching for in real-time. It tracks search volume for keywords, topics, and questions across Google Search, YouTube, Images, News, and Shopping. You can compare terms, see regional interest, and explore related queries that are rising in popularity.
For hackathons, Google Trends validates whether your idea solves a real problem people care about. If searches for "mental health apps" are rising 200% year-over-year, building a wellness chatbot isn't just creative—it's solving a documented, growing need. Judges love data-backed problem statements.

Why Google Trends is a Validation Superpower
Google Trends turns hunches into evidence. Instead of guessing whether people care about your problem, you can show judges a graph: "Searches for 'student budget tracker' have grown 150% since 2022." This transforms your pitch from "I think students need this" to "The data proves students need this."
Trends also reveals geographic and demographic patterns. Discover that your idea is popular in specific regions or spiking during certain times of year? Tailor your hackathon project to that audience. Judges appreciate solutions designed for specific, validated user segments.
- Real-time search data: See what's trending right now globally or locally
- Compare up to 5 keywords: Validate which solution approach is more popular
- Filter by region: Discover where your target audience is concentrated
- Time ranges: Past hour, day, week, month, year, or custom date ranges
- Related queries: Find what else people search for (discover adjacent problems)
- Rising searches: Identify breakout trends before they peak
- Category filters: Technology, Health, Finance, etc. for focused insights
- Export data: Download CSVs to include in pitch decks or demos

How to Use Google Trends for Hackathons
Start with broad problem areas. Search terms like "affordable housing," "study productivity," or "climate action." Look at the trend line: is it rising, stable, or declining? Rising trends indicate growing problems worth solving. Flat or declining? Might not resonate with judges.
Next, compare solution approaches. Searching for a fitness app? Compare "workout planner" vs. "personal trainer app" vs. "fitness tracker." The highest search volume tells you what language users prefer and which angle to pitch. Use this data in your Devpost submission and presentation.
- Go to trends.google.com and search your problem area keyword
- Check the trend direction: rising trends = growing problems
- Click "Compare" to add alternative keywords or solution approaches
- Filter by region to target specific markets (e.g., "United States" for US hackathons)
- Scroll to "Related queries" to discover adjacent problems or features
- Look for "Breakout" queries (marked with up arrow) for emerging opportunities
- Export data as CSV or screenshots for your pitch deck
- Use "Past 5 years" range for long-term validation, "Past 90 days" for urgency

Pro Tips for Trend-Based Ideation
Cross-reference Google Trends with hackathon sponsor categories. If a hackathon has a "sustainability" track and Google Trends shows "carbon footprint tracker" rising 300%, you've found a validated idea aligned with prizes. This strategic alignment increases your chances of winning sponsor awards.
Use "Related queries" to discover subproblems. Searching "remote work" might reveal "virtual team building" or "timezone converter" as rising queries. These are specific, solvable problems you can tackle in 24 hours. Judges prefer focused solutions over broad, vague products.
- Search sponsor keywords: If Goldman Sachs sponsors, search "fintech" trends
- Look for seasonal spikes: Tax season? Budget apps trend. Back to school? Study tools spike
- Compare your idea to competitors: "Notion" vs "Obsidian" shows market share
- Use YouTube Trends (filter on left): Video content trends reveal demand
- Check "Interest by region": Build region-specific solutions for niche markets
- Combine with GitHub Trending: Tech trends + search trends = winning combo
- Screenshot trend graphs for pitch slides: visual proof of demand
- Search problem + "app" vs problem + "tool" to see preferred format

Validating Ideas Before You Code
Before writing a single line of code, validate your idea with Google Trends. If your target keyword has declining interest or negligible search volume, reconsider. Judges ask "Why does this matter?" and your answer can't be "I don't know." Show them the trend line instead.
The best hackathon projects solve problems that are: (1) Rising in search volume, (2) Specific enough to solve in 24 hours, and (3) Aligned with hackathon themes. Google Trends helps you check all three boxes before you commit to building.
