Why Google's device-level bidding is 'hugely important'
Google’s online advertising service, Google AdWords, has become a major marketing and advertising tool in recent years.
It allows marketers to place search results for their website on a search engine results page (SERP) by paying for them, instead of just waiting for a website to work its way slowly and organically up the rankings.
Advertisers bid competitively to display brief advertising copy to web users, linking the copy to the content of the web pages that has been searched for and according to which device has been used.
The number of variables that need to be taken into account when predicting the value of a click in search marketing campaigns is so complex that only sophisticated, automated algorithms are able to make sense of this huge quantity of data.
Now Google has launched a significant change that will give advertisers far more control over device-level bidding. With the huge increase in the number of Google searches taking place on mobiles, rather than desktops and tablets, Google has announced that it will soon change the way that advertisers set bids for targeting ads by device type, allowing users to bid separately for tablet and desktop traffic again.
This is a development that users have been hoping for ever since this function was removed back in 2013. It is significant because it will greatly enhance the ability of advertisers to improve their performance on mobile devices.
Back to the future
Prior to the release of Google’s ‘Enhanced Campaigns’, which reduced mobile bidding options, Google was on track to add more dimensions for advertisers to optimize and better reach their target audience.
They were quick to add the ability to bid separately for iOS and Android in the early smartphone days and later added new ways to control search query matching with Broad Match Modifiers released in July 2010.
But, with the move to Enhanced Campaigns in July 2013, Google switched its focus to bidding simplicity. The company removed many of the tools that advanced advertisers were using to get the most out of their ad spend.
With every added dimension, there are new pockets of performance to be exploited
Google decided that the results and user experience of tablets and desktops were very similar and decided to group them together as one type of device for bidding purposes. This meant there was no option to separate out tablets and desktops, regardless of how well or badly they performed.
It also meant that Google was able to restrict control over which devices marketers would like their ads to be shown on, and how much they were willing to pay for them.
Marketers know that user behaviour on different devices varies significantly, and a blanket bid across all three (desktop, mobile and tablet), with just the ability to bid up or down on mobile, isn’t suitable for this sort of user dynamic and so they weren’t at all happy with the change.
For some advertisers, it was devastating, with conversion rates varying wildly between tablets and desktops. In some cases, double-digit performance efficiencies were lost by these removed dimensions.
Now with the announcement that this feature is coming back, Google will allow individual bidding across all device types, with the option to select which device is the primary target.
The re-introduction of tablet bidding is hugely important for several reasons:
- Promoting device applications goes beyond App Ads: For a business that promotes a tablet app as part of their business model, the conversion rate and flows of acquiring customers can vary wildly between desktop and tablet searchers. If you have a model where users searching on a tablet arrive at a web browser landing page with a full or partial goal to download an app, that experience will be very different from the desktop experience. By the same token, desktop performance can also be improved as it will no longer need to make trade-offs with tablet performance
- Behavior and intention changes by time and device: The behavior and intention of consumers at different times of the day can be very different across devices. From using a phone during the morning commute to a computer at work to picking up a tablet in the sofa after dinner. As the devices and times of day vary so does what the user is searching for. This has a large impact on purchase intentions and something that can be optimized for at the device-level using high-frequency bidding
- Bidding with high frequency across devices: Advances in Predictive Search Bidding makes advertisers able to understand and optimise to the differences in device behavior using high-frequencyy bidding. With the right technology to predict and bid on the differences in hourly conversion behavior, additional performance can be gained. And with tablet adding to this mix, this potential will become even greater
- Device modifiers versus keyword bids: From the information released so far, it seems that Google’s strategy is still centered on using bid modifiers, and that these modifiers will still be placed on an ad group level. For advertisers who wanted to bid to devices at the keyword level, they have had to either use single-keyword ad groups or create campaigns using a +300% mobile modifier to try to capture only mobile traffic in a separate campaign. These strategies have required either greatly increased complexity in managing accounts, or have included “leakage” of desktop traffic into the mobile campaign, making it hard to optimize to the right target
- Pure device campaigns - With the base bids getting introduced by Google, advertisers may have the option to take back keyword control of their device bidding. If it ends up being possible to set a tablet as the base bid in one campaign with desktop and mobile at -100%, and then duplicate that strategy for desktop and mobile across two campaigns with the same content, a marketer could choose to bid on every device with its correct value on a keyword level. The trade-off would be having three times the amount of campaigns to manage, but for advertisers who have a smart, automated bidding solution, this move could have a huge impact on their marketing performance
I applaud this move by Google and hope they will keep going. My hope is that the next move for Google will be to increase its capabilities for audience targeting and add back important features like bidding to phone or browser type (let’s hope this doesn’t take another three years).
With every added dimension, there are new pockets of performance to be exploited and used to a competitive advantage.
