But here’s the good news: you don’t need to spend a dime on expensive SEO tools to find these trends. With the right approach and free resources, you can uncover what’s trending globally and shape your content to match.
In this blog, we’ll explore 7 proven, free methods to discover trending keywords worldwide—so you can boost SEO rankings, create viral content, and stay ahead of the curve.
1. Use Google Trends for Global Insight
Google Trends is one of the most powerful free tools available for keyword research.
How to use it effectively:
-
Explore global and regional trends using filters for country, time, and category.
-
Check the “Rising” and “Breakout” keywords to find what’s gaining momentum.
-
Use related queries to expand your keyword list.
👉 Example: If “AI tools” is trending in the US, Google Trends can show related queries like “best free AI tools” or “AI tools for students,” helping you refine your content strategy.
2. Leverage Google Keyword Planner (Free via Google Ads Account)
Google Keyword Planner, while designed for ads, is a goldmine for SEO.
Why it’s useful:
-
Discover search volume ranges for keywords.
-
Identify seasonal spikes and long-term growth.
-
Compare keyword performance across different regions.
💡 Pro Tip: Even if you don’t run ads, you can set up a free account and still access this tool’s insights.
3. Explore Google Search Autocomplete & People Also Ask
Have you noticed how Google suggests keywords as you type? That’s Autocomplete at work.
-
Type a seed keyword (e.g., “fitness”) and see what Google suggests—like “fitness apps 2025” or “fitness for beginners.”
-
Check the People Also Ask section for question-style queries—perfect for blog titles and FAQ content.
These insights reveal real user intent—exactly what people want answers to.
4. Tap Into Social Media Trends
Social platforms are keyword trendsetters.
-
X (Twitter): Check trending hashtags and keywords under “Explore.”
-
TikTok Creative Center: Shows trending searches, sounds, and hashtags worldwide.
-
Instagram Explore: Great for niche trends.
-
Pinterest Trends: Ideal for lifestyle, fashion, and DIY content.
👉 Example: If TikTok users are searching “AI résumé builders,” chances are this keyword will soon appear in Google searches too.
5. Scan Forums & Online Communities (Reddit, Quora, Niche Forums)
Communities are real-time goldmines for trending topics.
-
On Reddit, explore trending threads in your niche (e.g., r/SEO, r/Health).
-
On Quora, check “hot questions” and track what users ask repeatedly.
These keywords come straight from authentic user conversations, which makes them highly relevant and less competitive.

Sometimes the best way to find trends is by seeing what’s working for others.
-
Use SimilarWeb (free version) to check top competitor traffic sources.
-
Review BuzzSumo’s free insights for trending content and keywords.
-
Manually analyze top-ranking articles in your niche for repeating keyword patterns.
👉 If multiple competitors are publishing content on a rising topic, that’s a strong signal you should too.
