EosBot Viral Product Principles
A compact, opinionated playbook of 32 principles for building products that people want, pay for, and share. Each principle is a single lever you can pull on a landing page, pricing page, or launch. Use them as a checklist when reviewing your own product surface — if a principle is violated, that is a concrete, fixable defect.
How to use this skill
- Before building or rewriting a product surface, skim the principles below.
- Pick the 3–5 most relevant to the current page (e.g. a pricing page → principles 8, 17, 18, 29, 30).
- Review the surface against those principles and list violations.
- Fix the highest-impact violations first.
The 32 principles
1. Kill the free plan
Free users drain support and servers, and fewer than 3% convert. Focus on the people who pay.
2. Hard paywall
Signups don't pay the bills. Ask for payment before you ask for data. No credit card, no real validation.
3. Numbers > adjectives
"Fast" is forgettable. "Save 4 hours a week" is tangible.
4. Shareable footer
97% won't buy, but they might share. End the page strong and memorable.
5. OG image = YouTube thumbnail
The preview image of your link is seen more often than your site. Design it to earn the click.
6. Show before you explain
A visual demo communicates more than paragraphs. Show, don't tell.
7. Extreme simplicity
Complexity kills curiosity. Use words your mom or a 5th-grader would understand.
8. The 3-color rule
Black text. White background. One vivid color for the buy button. More colors steal attention from what matters.
9. Uncopyable copy
If a competitor can copy-paste your text onto their site, your copy is generic. Write from your own experience.
10. One idea per screen
Don't say everything at once. One screen = one message (like the Instagram feed).
11. Do exactly one thing
Nobody remembers Swiss Army knives; they remember the tool that solved their problem. Be known for one thing.
12. Surf a wave
Build around trends, technologies, or problems already being discussed (e.g. AI). The wave does half the marketing.
13. Sell in the hero section
80% of visitors don't scroll. If they don't understand and want the product in the first seconds, you've lost them.
14. Steal the customer's copy
Your customers describe the product better than you do. Write like they speak.
15. Show your face
People buy from people. A founder screen-recording converts better than a polished corporate video.
16. Memorable, emotional headlines
Write for humans. Your headline should provoke a laugh, shock, or curiosity — and be remembered 24 hours later.
17. Popcorn pricing
Simplify. Offer only three options: Good, Better, Best. More options cause decision paralysis.
18. Highlight the price
Put "Pricing" in the header. It's the first thing people look for to understand value.
19. Empathy first
Before trusting your solution, the customer needs to know you understand their pain. Describe the problem better than they would.
20. Specific CTA
"Get started" means nothing. "Analyze my site" removes uncertainty about what happens on click.
21. Social proof is non-negotiable
Never launch without testimonials. Get beta testers first; blind trust from strangers doesn't work.
22. Comparison table
People don't care what you do, they care why they should switch from the tool they already use. Make the decision easy with a clear table.
23. Single CTA
More buttons = hesitation. Give exactly one next step.
24. Sell the desire, not the feature
People buy status, time, health, money, or pain relief. Features are just the vehicle.
25. Let them play
Don't hide your best features. Put them on the landing page so people can try before paying.
26. No weak words
Avoid "most", "many", "rarely". Make strong, clear claims people can visualize.
27. The novelty factor
Nobody shares "another clone". Surprise people with something they've never seen.
28. Memorable name
Use known words. Avoid complex puns or names that need explanation.
29. Avoid subscriptions
People are tired of monthly fees. One-time payments are 10x easier to sell.
30. Charge more
Nobody talks about the second-cheapest option on the market. Charge more than your competitors.
31. The 10-word rule
If you can't explain your product in one sentence, your users can't either.
32. Author's closing insight
"If you found a 33rd principle, I'd love to hear it." — The iterative-building mindset never stops. Build fast, test in the market, adjust.
Anti-patterns to avoid
- Feature dumps — listing everything violates principles 10 and 11.
- Vague CTAs — "Submit" or "Get started" violates principle 20.
- Hidden pricing — violates principles 18 and 23.
- Generic copy — violates principle 9 (competitors can copy-paste it).
- No social proof at launch — violates principle 21.
Self-review checklist
After applying these principles to a surface, confirm:
- Hero section sells the product in < 5 seconds (13)
- Exactly one primary CTA (23)
- Price is visible and uses 3-tier or one-time model (17, 18, 29)
- Every claim is specific and number-backed (3, 26)
- At least one testimonial present (21)
- Copy is uncopyable / from real customer language (9, 14)
