How to Spot Fake or Inflated Case Studies
Five tells, five questions. The 90-second test that surfaces most fakes.
By the Launch Leads team · 5 min read · Updated April 2026
Spot inflated lead gen case studies with five tells and one 90-second test. The tells: anonymous client, no baseline, no timeframe, attribution skipped, and outcomes that don’t match plausible category benchmarks. For each tell, ask one question: can you connect me to the named contact, what was the baseline before the engagement, over what timeframe, what did your team do versus theirs, and is this median or your best case. Three or more tells means the case study is inflated.
The case study deck is impressive and you want to know what’s behind it.
Few B2B case studies are outright fabricated. Most are real engagements with the inconvenient parts cropped out. The numbers are technically true. The framing is what does the work — and the framing is where the inflation lives.
Five tells. A 90-second test. None of them fail-proof, all of them more useful than reading the case study at face value.
The thesis: an inflated case study has at least three of these patterns — anonymous client, no baseline, no timeframe, attribution skipped, and outcomes that don’t match plausible category benchmarks. The 90-second test is to ask one question for each pattern and watch the answer.

1. The five tells
1. Anonymous client. “A leading SaaS company saw 3x increase…” If they can’t name the client, the engagement either ended badly, never closed, or was a one-off pilot. Real successes get named.
2. No baseline. “We delivered 200 qualified meetings.” OK — was the baseline 0 or 180? Without a baseline, the impressive number means nothing. Real case studies always include the starting point.
3. No timeframe. “200 meetings” over what — a month, a year, the entire engagement? The smaller the timeframe, the more impressive the number; the absence of one tells you it’s been chosen for impressiveness, not honesty.
4. Attribution skipped. “We grew their pipeline by $4M.” Did the agency’s outreach create those opportunities, or did the client’s existing inbound, AEs, and brand work do most of the conversion while the agency’s name showed up in the activity logs? Real attribution names which side of the funnel each side worked.
5. Outcomes that don’t match category benchmarks. “We delivered a 40% conversion rate from cold outreach to closed deal.” That’s not a B2B benchmark — that’s the limit of physics in most categories. Pattern-match against your own category. Numbers far outside plausible ranges are usually inflation, not innovation.
“They’ll come through with what they say they can deliver, and they know their stuff. They’re able to get a foot in the door and get with the decision-makers at the companies you’re trying to get in with.”
— Dave Bascom, CEO, SEO.com
2. The 90-second test you can run on any case study
For each tell, one question:
- “Can you connect me to the named contact?” If the answer is “we’d need permission” — fine, ask for permission. If the answer is “they’re under NDA,” it’s worth less than the agency thinks it is.
- “What was the baseline before the engagement started?” Should produce a specific number, not a hedge.
- “Over what timeframe?” Should produce a specific date range.
- “What did your team do versus what their team did?” Real agencies have a clear answer here. Inflated ones describe the engagement as if the agency did everything.
- “Is this representative of the median engagement, or is this your best case?” Honest answer: “Best case.” Then ask for median.
Five questions. Ninety seconds. The answers separate inflation from honest reporting in nearly every case.
3. What good case studies actually look like
A real case study includes:
- Named client and contact (with permission to verify)
- The baseline with specific numbers
- The timeframe with specific dates
- Attribution split — what the agency drove, what the client drove
- What was hard — every real engagement has hard parts; case studies that don’t mention them are marketing
- What’s typical vs. exceptional about this result for the agency’s book
A case study with all six is rare. A case study with four of six is good. Anything below three is the agency telling you what they think you’ll fall for.
How to use this list
Read each finalist’s top case study. Run the 90-second test. The case study that survives the test is the one to weight; the case studies that don’t are the ones to mostly ignore.

Frequently asked questions
Are most lead gen case studies inflated?
Most are framed favorably — that’s not the same as inflated. The 90-second test sorts honest framing from real inflation. Roughly 1 in 3 case studies fails the test in our experience.
What’s a fair lead gen case study to share with my team?
One with named client, baseline, timeframe, attribution split, and contact info for verification. Anything less is marketing material, not evaluation material.
What if all the case studies are anonymized?
That’s a category-level signal in two directions: (a) the agency works with clients who require anonymity (sometimes legitimate), or (b) the agency hasn’t built relationships strong enough to get permission. Ask which.
Should I weight case studies or references more heavily?
References. Case studies are the agency’s framing of the engagement; references are the client’s framing. The two often diverge.
Can I use these tells on agencies in adjacent categories?
Yes. The patterns travel across any agency category that produces case-study marketing.
