In rare cases Google Ads keeps a conversion and later invalidates and removes the click that led to it. Before the billing period ends, invalid traffic is removed from both the invoice and the metrics. A credit after the invoice does not rewrite metrics.
One Direct campaign can block impressions for no more than 25 IP addresses. The help does not recommend the block even when activity looks suspicious: the address changes, and a proxy gives one IP to many people.
VK Ads help explains fast spend by the bid, a wide audience and a second-price auction. That page does not mention bots or refunds. How to read eCPM, and what placement settings do not prove.
Full access in Direct can edit ads and pay; read-only keeps statistics without the balance. Metrica goals can be shared without counter access, and support sees the login that sent the request.
What Google calls traffic with no real interest, when a click is removed from the bill, and why an IP exclusion does not zero the site logs. A campaign checklist.
How a Yandex Direct weekly budget, learning window and restart spend faster than the account expects, and what to check before calling the week a loss.
Which daily ceiling a Yandex Direct weekly budget sets, when changing the budget restarts spend, how underspend carries over, and why impressions can stop in the morning because a sum is frozen for review.
Why a CRM is uploaded to Metrica, which deadlines yclid and an order edit have, how a value for advertising cost share differs from a payment fact, and why the CRM still shows visits Direct has already filtered.
Where Direct puts offline conversions, which identifiers are written into a visit, why yclid has 21 days, and how a manual link differs from the last visit.
Which ready-made Yandex Direct retargeting segments include bounces and ad traffic, why several goals must happen in one visit, and how many minutes a segment takes to catch a person.
What the VK Ads help pages do not say about invalid clicks, how the second-price auction and eCPM work, and what “click verification” actually does.
Yandex Direct adjustments run from −100% to +1,200%, how they change average click and conversion price, and why −100% on smartphones removes more than apps.
How to block apps on a Yandex Direct placement list, how that list differs from a −100% smartphone adjustment, and which limits the help sets for domains and impression places.
Where a placement block lives in Yandex Direct, how the banner limit differs from the limit in the networks FAQ, and why the help does not describe an account-wide list. Alongside, how placements are chosen in VK Ads.
The Invalid clicks column is clicks Google Ads has already filtered, and they are not charged. How that column differs from a credit, and why an IP exclusion does not empty the site logs.
Conversions Direct has marked as fraud do not train the strategy. What it trains on instead: 10 goal completions a week, the report price, and a mid-week budget restart.
Direct’s antifraud runs before the impression, on the click, and after the visit. How it differs from Metrica’s robots, and why fraud can still reach the site.
Direct’s geotargeting looks past the current pin, and the schedule limits impressions, not a click on an old tab. How to set region, hours, and holidays.
A Yandex Direct campaign can list up to 25 IP addresses, and the help page still advises against the ban even when activity looks suspicious.
