"Header bidding means every advertiser competes for your slot"
The pitch is real: simultaneous auctions beat the old waterfall. Genuinely better mechanism.
The asterisk: "every advertiser" is actually a handful of demand partners (SSPs) the network bothered to integrate, each bidding on behalf of buyers who've already decided your inventory is worth bidding on. More auctions don't create demand — they only surface demand that already exists for your audience.
🚩 Hidden variable: demand depth for your inventory. Header bidding on a Tier-3, low-viewability site is a fierce auction with two bidders and no floor pressure. The mechanism is sound; the room is empty.
Not saying header bidding is hype — saying it redistributes existing competition more efficiently; it can't manufacture buyers who don't want your impressions.

"I switched to Raptive and revenue jumped 40% overnight"
Grant the steelman: header-bidding setups and premium demand really can lift a site, sometimes a lot.
The asterisk: nobody switches networks in a vacuum. The switch usually coincides with a seasonal demand ramp (Q4), a fresh ads.txt finally propagating, or the old network's setup having been quietly broken for weeks.
🚩 Hidden variable: the baseline you're comparing against. "40% lift" measured against a degraded final month on the old network isn't a 40% lift — it's a recovery plus a clean install.
The honest test is same-month-last-year, not last-week. Almost nobody runs it.
Not saying Raptive didn't help — saying "overnight 40%" is measuring a clean install against a broken one and calling the gap performance.

"I A/B tested both networks for a week each"
Credit where due: alternating is smarter than most people bother to do.
But display revenue carries an attribution and reconciliation tail. Week-one's reported earnings include impressions still settling, and week-two's network gets credited with demand primed during week one. Sequential testing bleeds across the seam. You measured a handoff, not two clean states.
🚩 Hidden variable: the reconciliation lag overlapping your switch date. Most networks finalize 3 to 7 days out; some exchanges, longer. Your clean A/B has a smeared boundary you can't see in daily totals.
If you must sequence, throw away the first and last 5 days of each arm. Better: split by page-group simultaneously so both networks face the same week's demand.
Not saying A/B testing is bad — saying the comparison is rigged.

"Mediavine pays 2x what Ezoic does"
The steelman: yes, side-by-side screenshots routinely show Mediavine RPM double Ezoic's. That part is real.
The asterisk: those screenshots almost never come from the same site. They come from a food blogger (US desktop, long dwell time, sticky sidebar units firing on scroll) vs a tech site (mobile-heavy, bounce-fast, viewport never reaches the second ad).
🚩 Hidden variable: viewable impressions per session. Mediavine's lazy-load + sticky stack gets 4-6 viewable units per pageview on a recipe scroll. The same layout on a 400-word answer post fires 1.5.
Move your traffic mix and the "2x" compresses fast.
Not saying Mediavine is worse — saying the comparison is rigged by who's holding the screenshot.

"My dashboard says $1,400 — but I got paid $1,150"
Not a scam. It's how the money actually moves.
The dashboard shows gross estimated revenue, often in real time, before three deductions land:
— Network rev-share (the 10-20% the network keeps, sometimes shown net, sometimes not)
— Advertiser clawbacks for invalid traffic, posted 30-60 days late against a month you already "earned"
— Currency and payment-processor skim on the way out
🚩 Hidden variable: the reconciliation lag. Today's estimate is settled by Google/advertisers up to 60 days later, so the number you screenshot is never the number that clears.
Not saying your network is shorting you — saying "dashboard number" and "bank number" are two different metrics measured at two different times.
