Reporting discrepancies are common and expected when multiple systems are used in your line items. When DFP delivers line items that are hosted by RITS Ads or any third party server, reporting discrepancies between the two systems will occur, and it is common to see campaign variances of up to 20% and it is accepted by DFP users, even though internationally the acceptance rate is 10% only.
There are several reason for this reporting discrepancy between Openx and DFP report. You should consider the followings to investigate the reporting discrepancy:
Latency: Lag between an initial line item request and the appearance of the creative can lead to differences in counts. For instance, a user will often navigate away after the browser receives the DFP line item request but before the third party responds with the requested line item, or a user may click on a link but navigate elsewhere before the landing page has loaded.
Network connection and server reliability: A third-party ad server may fail briefly or encounter an issue that prevents it from logging an impression.
Ad blockers: Ad blocking software can prevent the line item from being delivered by the third party after DFP has already counted an impression.
Low impression goals: A small numerical discrepancy can cause a high percentage discrepancy if the line item delivered few total impressions. For example, if you have a campaign delivering 100 impressions per day, a single-day discrepancy of 30 impressions will lead to a single-day discrepancy of 30% even though the actual number of missed impressions is low.
Tracking methodologies: DFP counts line items requests, but a third party may record an impression at a different time (e.g., when a tracking pixel is rendered).
Filtering: Ad servers have different methods for filtering impressions from spammers, bots, spiders, back-to-back clicks, link analyzers, and other automated or non-representative web traffic.
Testing: DFP excludes impressions or clicks from anyone with an IP address that has signed in to a DFP account before. Third parties do not necessarily do so.
OpenX has overtaken Google as the most trusted inventory source, according to figures released this week, as the latter of the pairing aims to underline its leadership in the industry’s fight against dishonest players.
The claims were made in the latest update toPixalate’s Global Seller Trust Index (GSTI), which ranks inventory quality and security risk, with the company further revealing that 70% of media inventory sources are exposed to malware-driven ad fraud, with one-in-20 internet users infected by it.
Overall, OpenX ranked as the most highly-rated source of traffic in April, overtaking Google AdExchange, which had led the table the previous month (see chart immediately below).
Meanwhile, both OpenX and Rubicon Project are leading in five categories each, while Google’s AdExchange leads in two (see chart below).
Commenting on the numbers, Jalal Nasir, Pixalate, CEO, said addressing the issues of cyber security risks, plus the concerns they pose to both enterprises and consumers, was crucial if high-level marketers are to place further trust in programmatic media buying.
The complexity of the programmatic advertising sector means it is particularly vulnerable to malicious players in the ecosystem, as it gives them a means to hide their true identity, according to Nasir.
He added: “This is a complex and growing problem, as many buyers, including reputable brands, purchase seemingly legitimate inventory. Unbeknownst to them, some of the inventory has been compromised and ultimately leads to a negative impact on consumer trust and brand integrity.”
Pixalate’s GTSI analyses 100 billion ad impressions, across 350 million IP addresses in order to benchmark 400 programmatic media sellers by assessing their vulnerability to darknets, owned and operated by malicious organisations. The latest version of the report also revealed that breaks sellers down by IAB verticals (see chart below).
Google’s efforts to combat fraud
Meanwhile, Google has been at pains recently to demonstrate that it is at the vanguard of the drive to clean up ad tech, post its purchase of Spider.io last year.
The advertising behemoth recently granted industry journal Ad Age access to its 100-strong anti-fraud team in London to offer the industry further insight to its efforts to combat botnets, which are credited as siphoning off $6.3bn from the digital advertising sector each year.
The piece demonstrates the ease with which hackers can hijack machines – through security weaknesses it calls ‘exploits’ – to create botnets that then click on ads en masse, and further profiles Google’s efforts to combat the fraudsters behind them.
He added: “When fraud is identified it should be shared in a clear structured threat disclosure, mirroring how security researchers release security vulnerabilities. By increasing the amount of data we share in a transparent, helpful way, others in the industry will be able to corroborate any claims being made, remove the threat from their systems, removing it from the ecosystem.”
Johnsen goes on to advocate a system whereby any party that purchases non-blind impressions should be passed a chain of unique supplier (and reseller) identifiers – be it an exchange, network, sell-side platform – and one for the publisher.
He added: “With this full chain of identifiers for each impression, buyers can establish which supply paths for inventory can be trusted and which cannot.”
Mikko Kotila, industry veteran, and author of last year’s WFA report advising brands on transparency in the programmatic buying sector, recently dropped by the ExchangeWire office to discuss his not-for-profit outfit Botlab.io, aimed at helping clean-up the sector.
In the TraderTalk TV episode below, Kotila discusses his view that independent bodies are better placed to combat fraud, compared to security firms or trade bodies, as the latter are incentivised for profit.
