Most buyers treat the seller call as a formality — a polite 30 minutes between reviewing the P&L and signing the LOI. That's a mistake. The seller call is the single highest-leverage hour in your entire diligence process, and almost nobody runs it properly.

I've sat on both sides of these calls. As a buyer, I've asked the questions. As someone who has helped sellers prepare, I know exactly what they're bracing for and what they're hoping you won't ask. And the pattern is remarkably consistent: buyers ask predictable questions, sellers give rehearsed answers, and both parties hang up having learned nothing that wasn't already in the listing.
That's a waste. Financial statements tell you what happened. Google Analytics tells you where the traffic came from. Ahrefs tells you which keywords are ranking. None of those tell you why revenue dipped in Q3 of last year, or that the site's best-performing article was written by a freelancer who no longer takes work, or that 40% of affiliate revenue comes from a program whose commission structure is quietly under review.
Sellers know those things. They will often tell you those things — but only if you ask in a way that makes it safe and natural to answer honestly. This guide is about building that conversation.
Start with the incentive structure. A seller has spent years building this business. They've made money from it, they've lost sleep over it, and they've decided to exit. They're motivated to present it favorably — not because they're dishonest, but because that's how human beings talk about things they've built. Ask any founder to describe their business and you'll get the highlight reel by default.
At the same time, sellers carry an enormous amount of undocumented knowledge. On a typical content site doing $8,000/month in profit, maybe 60% of what actually makes the business work exists in the operator's head: which writers deliver without hand-holding, which affiliate manager responds to emails, which pages you never touch because they're fragile, which competitor got aggressive last spring. None of that is in the CIM. All of it affects your first twelve months of ownership.
Here's the part most buyers miss: sellers want to talk about this. Running a small online business is isolating. Nobody in their life understands what they do. You are, quite possibly, the first person in years who is genuinely interested in the operational details of their business. If you show up curious rather than adversarial, most sellers will tell you far more than they legally have to.

The quality of your seller call is determined before the call starts. If you get on Zoom having skimmed the listing that morning, you'll ask generic questions and get generic answers. Preparation is what turns a 45-minute call into something that materially changes your valuation.
Before the call, review everything you have: the prospectus or CIM, the profit and loss statements month by month for at least 24 months, Google Analytics traffic data, Google Search Console impressions and clicks, and your own third-party research from Ahrefs or Semrush. Read them looking specifically for anomalies — the month where revenue jumped 40%, the quarter where traffic declined while rankings held, the expense line that appears twice then vanishes, the top-10 keyword that dropped to position 34 six months ago.
From those anomalies, build a written list of 15 to 20 specific questions. Not "how's traffic been?" but "I noticed sessions dropped about 22% between March and June last year while your top keywords held rankings — what happened there?" Specificity signals that you've done the work, which changes the seller's posture immediately. Vague buyers get managed. Prepared buyers get engaged with.
This is also where market context matters enormously. If you don't know what a normal content site's revenue-per-session looks like, or what typical Amazon Associates conversion rates run in a given niche, you can't tell whether the seller's numbers are impressive or alarming. That's exactly the gap Deal Alert AI was built to close — tracking listings across marketplaces so you know what comparable businesses look like before you sit down with any specific seller.
A good seller call has a shape. It moves from low-stakes to high-stakes, from rapport to substance. Jumping straight into "explain your traffic decline" puts the seller in defensive mode for the entire call, and defensive sellers give you nothing.
Here's the structure I use, and roughly how long each segment should take on a 60-minute call:
You won't hit these times exactly, and you shouldn't try. If a seller opens up in the operations section, let it run. The agenda is a map, not a script. But if you find yourself 40 minutes in and still on business history, you've lost control of the call and you'll run out of time before the questions that matter.
"Walk me through a typical week" is the most underrated question in acquisition diligence. Listings routinely claim "5 hours per week." Sellers, when actually walking through their week out loud, will describe publishing schedules, writer coordination, affiliate check-ins, technical maintenance, and email responses that add up to fifteen. Not because they lied — because they never counted.
Follow it with the failure question: "If you were gone for a month, what would break first?" This gets you the fragility map. Sometimes the answer is "nothing, honestly, it'd be fine" — and that's a genuinely great sign for a passive content asset. More often you'll hear something like "the writers would stop delivering because I approve every brief" or "inventory would run out because I place orders manually." That's a real answer. Now you know what you're buying and what you need to systematize in month one.
On revenue, push for concentration. Which pages drive the money? On a lot of affiliate sites, three to five articles produce 50-70% of total revenue. That's not automatically bad — it's normal — but it changes your risk profile completely. If one review post generates $4,000 of $7,000 monthly profit and it sits at position 2 for a keyword a well-funded competitor is actively targeting, you're not buying a diversified content site. You're buying one article with a portfolio attached to it.
There are two questions I never skip, and they consistently produce more useful information than the other eighteen combined.
The first: "If you were buying this business, what would concern you? What would you investigate most carefully?" This is remarkable in how often it works. It reframes the seller as an advisor rather than an adversary, and most people — genuinely, most people — respond honestly. I've heard sellers say things like "I'd want to look hard at whether that Amazon category keeps its commission rate," or "honestly, the email list hasn't been worked properly in a year and that's where I'd focus," or "the Google update in March hurt three of my competitors and I don't fully understand why it didn't hurt me." Those are gifts. Nothing in the CIM would have surfaced any of them.
The second: "Why are you selling now, specifically? Why not six months ago, or eighteen months from now?" Vague answers — "just ready to move on," "focusing on other projects" — are not necessarily lies, but they're not information either. Specific answers are almost always genuine: "My wife's job relocated us and I'm losing my work rhythm," "I raised a seed round for a SaaS product and can't split attention," "I want to buy a house next year and this is my down payment." Specificity correlates strongly with truth because fabricated reasons tend to stay abstract.
The reason-for-selling answer also has to reconcile with the timing of the sale relative to the business's trajectory. If someone is selling a site at the exact moment traffic peaked after two years of steady growth, and their reason is "just felt like the right time," dig further. Not accusatorially — just ask what the next twelve months would have looked like if they'd kept it. Their answer to that tells you what they actually believe about the asset's future.
The transition conversation is where deals quietly go wrong. A business that looks clean on paper can be operationally unbuyable if too much of it depends on relationships or knowledge that don't transfer.
Ask directly: "What aspects of the transition are you most concerned about?" Sellers who have thought seriously about handover will have answers ready — a documented SOP library, a named VA who's been there two years, a writer roster with rates and turnaround times. Sellers who haven't will pause. That pause is data. It usually means the business runs on the seller's improvisation rather than on systems, and you're going to spend your first quarter rebuilding processes instead of growing.
Then get specific about relationships. Is there a direct-deal advertiser who signs because they like the seller personally? A supplier offering favorable terms based on a five-year relationship? An affiliate manager granting an above-standard commission rate as a personal courtesy? These arrangements are real economic value, and they frequently don't survive ownership change. I've seen a $9,000/month business lose $1,800/month of direct sponsorship within 90 days of close because two advertisers simply didn't renew with the new owner. That was in nobody's spreadsheet.
Where you find transition risk, structure around it. Extended training periods, a consulting retainer for 90 days, or an earnout tied to retention of key revenue relationships all work. Marketplaces like Empire Flippers have standardized migration processes that reduce this friction considerably. On Flippa, where listings vary far more in quality and preparation, the transition conversation carries proportionally more weight — you're doing work the platform isn't doing for you.
Hang up, and before you do anything else, spend twenty minutes writing. Not summarizing — analyzing. There are four questions worth answering while the conversation is still fresh.
First: what did the seller say that they didn't intend to say? Offhand remarks are gold. "Oh, that was back when we were still doing the Facebook ads" — you didn't know there had ever been paid traffic. "Once the new writer got up to speed" — you didn't know there'd been writer turnover. These fragments open threads worth pulling.
Second: what did they emphasize most? People over-explain the things they're anxious about. If a seller returns three separate times to reassuring you that the Google algorithm risk is manageable, that's the thing keeping them up at night. Third: what topics were they least comfortable with? Note where energy dropped, where answers got short, where they redirected. Fourth: what did I fail to ask? There's always something. Put it in a follow-up email — sellers answer written questions in writing, which gives you documentation.
Then reconcile everything against the documents. Every claim made verbally should be checkable against the P&L, analytics, or a third-party tool. Where the story and the data agree, your confidence goes up. Where they diverge, you have a specific question for round two — and there should always be a round two on any deal above roughly $50,000. One call is an introduction. Two calls is diligence.
The final piece is comparison. A seller call in isolation tells you about one business. A seller call informed by market context tells you whether that business is a good deal.
If you know that comparable content sites in the same niche are transacting at 38-42x monthly profit, a 45x asking price becomes a specific negotiation point rather than a vague feeling. If you know that similar-sized Amazon affiliate sites typically run 8-12% of revenue on content production, and this seller is running 3%, you can ask the obvious question: is the content pipeline underinvested, and what does it cost to bring it to standard? That question changes your model. It might change your offer by five figures.
This is why I built Deal Alert AI — to give buyers continuous visibility into what's actually listing and selling across the major marketplaces, so you walk into every seller call with a baseline instead of a guess. Pattern recognition across hundreds of listings is what separates buyers who negotiate from buyers who accept. You can't develop that from looking at one deal at a time.
The seller call isn't a formality and it isn't an interrogation. It's the one hour where you get access to the operator's actual understanding of the business — the context, the fragility, the things they'd worry about if they were you. Prepare for it properly, run it with genuine curiosity, analyze it afterward, and it will consistently tell you more than any document in the data room. Get in the habit of tracking deals on Deal Alert AI before you're in a live process, and by the time you're on that call, you'll already know which questions matter most.
