What every part of a topic card means
Here is a real card from the Trend Lab. Each colour and number is a clue. Green is good, yellow is OK, red means “be careful”.
What is keto? The Complete Answer
The best type of PDF for this idea: Guide, Checklist, Ebook, Planner, Worksheet, Cheat sheet or Report.

Good: Breakout, Rising or Evergreen. Skip: Cooling.The overall score from 0 to 100. It mixes demand, trend, PDF fit, effort and competition into one number.
Good: 60 or more. But never choose by this number alone.How many people are searching for this, compared with the other ideas in your search.
Good: 50 or more. The higher, the bigger the audience.How well the idea works as a PDF. “How to”, plans, lists and checklists score high. News and famous names score low.
Good: 50 or more.How much work the PDF will take. “101 recipes” is a lot of work. “A 7-day plan” is less.
Good for beginners: Easy or Medium.A quick label for the Demand number.
Good: High, or Medium if the topic is Rising.An estimate of how many big websites, videos and products already cover it. Low competition means it’s easier to get noticed.

Example: you searched “keto diet”. Which card would you pick?
Three real cards from the Trend Lab. Let’s check each one with the 5-point checklist.
Metabolic Psychiatry and Keto Diet: What You Need to Know
- Opportunity 76
- Low competition
- Rising +850%
- Medium effort
- Demand only 37
Few people search for it today, but interest is growing very fast and almost nobody has made a guide yet. If you publish early, you can be the first.
It’s a health topic, so use trusted sources and add a short “not medical advice” note.
101 Keto Diet Recipes
- Opportunity 78, the highest
- Demand 90
- Evergreen
- High competition
- Harder to make
It has the highest score, but thousands of free recipe sites and books already exist, and 101 recipes is a lot of work.
What is keto? The Complete Answer
- Opportunity 63
- Low competition
- Evergreen, sells all year
- Medium effort
- Demand 70, high interest
Lots of people want it, very few good guides exist, and it’s easy for you to make. Every beginner starts with this question.

Say who it’s for

Add tools, not just text
