50 Questions to Ask Before Buying an Online Business

The 30-minute call with the seller is the most leveraged hour in any acquisition. Documents can be curated, broker packages polished, and metrics cherry-picked — but a direct conversation reveals things no data room can hide. How a seller responds to hard questions tells you more than their P&L.

This list covers 50 due diligence questions organized by category. You won't ask all of them on a single call. Pick the 8–12 most relevant to the business type, and let the conversation go deep.

Reason for selling (the most important category)

1. Why are you selling now rather than 12 months from now?
2. What would you do with this business if you weren't selling?
3. Have you tried to sell this before? If so, why didn't that deal close?
4. What's the one thing about this business that keeps you up at night?
5. If you kept it, what's the growth lever you'd pull next?

Listen for hesitation. Sellers who genuinely want liquidity or are moving on to a new project answer these confidently. Sellers who are fleeing a problem give vague, rehearsed answers.

Revenue and financials

6. Walk me through exactly how this business makes money — not the summary, the actual flow from visitor to dollar.
7. What was revenue in each of the last 24 months? Can you share the actual numbers month by month?
8. Are there any one-time revenue events in the trailing 12 months that inflated the numbers?
9. What percentage of revenue comes from the top 3 sources?
10. Have any affiliate programs or revenue relationships changed terms in the past 18 months?
11. Are there any outstanding refunds, chargebacks, or revenue adjustments not reflected in the P&L?
12. What's your owner salary or compensation included in the expenses?

Traffic and SEO (for content sites)

13. What percentage of traffic comes from organic search vs. direct vs. social?
14. Has this site ever been penalized by Google or seen a significant algorithmic traffic drop?
15. Walk me through the top 10 traffic pages — are they evergreen or time-sensitive?
16. Who writes the content currently? You, freelancers, or a team?
17. What's the average traffic trend over the last 6 months — up, down, or flat?
18. Are there any pending content gaps or SEO issues you know about but haven't addressed?

Operations and time commitment

19. How many hours per week does this business require from you personally?
20. What tasks do you do yourself versus what's outsourced or automated?
21. Are there any contractors, VAs, or team members that would stay after a sale?
22. What software or tools does the business depend on? Are there any that are expensive or hard to replace?
23. Walk me through your typical Monday with this business.
24. What's broken right now that a new owner would need to fix?
25. Are there any vendor or platform relationships that are tied to you personally?

Customer and audience quality

26. How large is the email list, and what's the open rate?
27. Where did most customers/subscribers come from originally?
28. Do you have any recurring customers or members? What's the retention rate?
29. Have you ever surveyed your audience about why they use/follow this business?
30. What would make a current customer leave for a competitor?

Competitive landscape

31. Who are the top 3 competitors, and how do you differ from them?
32. Are there any new entrants in the past 12 months that concern you?
33. Is there any platform risk — would an Amazon, Google, or Facebook policy change significantly affect this business?
34. What's your sustainable competitive advantage? Why would a customer choose you over alternatives in 2 years?

Growth and upside

35. What's the biggest untapped opportunity you've identified but haven't executed?
36. Have you tested paid acquisition? Why or why not?
37. Is there a product or service the audience clearly wants that you haven't built?
38. What would you do in the first 90 days if you were staying as the new owner?
39. Are there partnerships or distribution channels you haven't explored?

Transition and post-sale

40. What's included in the transition period — how long, what's covered?
41. Are you willing to stay on as a consultant after the transition? At what rate?
42. Are there any non-compete agreements from previous employment that could affect this business?
43. Will you sign a non-compete for 2 years in this niche as part of the sale?
44. Are there any pending legal issues, disputes, or intellectual property questions?
45. What accounts and access will transfer — domain registrar, hosting, social accounts, analytics?

The psychological questions

46. What would have to happen for you to decide not to sell?
47. If the business were doing 50% better, would your asking price change?
48. What's your timeline — is there flexibility if the due diligence takes longer than expected?
49. Are there other buyers you're talking to?
50. What does a successful sale look like for you beyond the price?

How to use this list

Don't read these questions from a script. Come into the call with the 8 most relevant ones memorized, ask them conversationally, and follow the threads that surface. The best due diligence calls feel like a genuine conversation between two people who both want the deal to work — not an interrogation.

The seller's willingness to answer these questions thoroughly — or their hesitation around specific ones — is itself a data point. Transparency is contagious. Sellers who answer Question 4 honestly ("the thing that keeps me up at night") are almost always worth trusting on the rest. Sellers who deflect it have something to deflect.
