Device-specific PPC: Why it still matters today - Search Engine Land

Ever since bidding by instrumentality uniquely became disposable (sometime betwixt 2005–2011), I’ve been an avid advocator of separating PPC campaigns by device. (Well, but for tablets, due to the fact that nary 1 truly cares astir them anymore.)

Why?

For starters, determination is (at least) a 50% accidental you’re speechmaking this nonfiction connected a phone. And you’re astir apt alert that net and hunt depletion is dominated by mobile platforms.

Case successful point: looking astatine an ecommerce marque that virtually sells bacon online, I compared September 2022 vs. September 2009 website postulation by instrumentality and recovered that: 

• In 2009, mobile made up little than 1% and desktop made up 99%. 
• In 2022, mobile makes up 49% and desktop makes up 46% (total visitant maturation accrued by 504%). 

So yeah, mobile is simply a happening and should beryllium treated arsenic such.

Why doing PPC by instrumentality is important

As mobile net usage has grown implicit the past 10+ years, truthful has it accrued from the position of hunt marketplace share.

So overmuch truthful that astir verticals (not brands, but entire verticals) volition observe that mobile commands the bulk of postulation and walk erstwhile it comes to search. (Not you, B2B, you’re inactive bully with the aged desktop.)

This is incredibly evident successful user goods, brick-and-mortar locations, and brands with debased terms points and/or abbreviated acquisition rhythm windows.

Prior to 2017, you’d adjacent spot arsenic overmuch arsenic 50% little CPC connected mobile vs. desktop courtesy of little competition.

In immoderate scenarios, you inactive spot that. But the measurement coming from mobile was truthful high, it would offset the outgo savings connected the CPC side.

These days (ignoring PMax), the discounted level connected mobile is less, portion the measurement coming from mobile has greatly surpassed and overtaken that of desktop. 

In the lawsuit of a Caribbean QSR marque we enactment with, the mobile CPC is astir 32%. But mobile generates 17x the impressions and clicks than desktop, starring mobile to outspend desktop by 11x.

Then, we look astatine the situation of users looking astatine mobile devices. Consumer behaviour is antithetic than desktop. 

Mobile triggers contiguous engagement (i.e., “Hurry up and get what you need.”). 

On the different hand, desktop involves a sit-down experience, wherever radical probe and comparison portion taking their time. (I should note, this mentality had wholly flip-flopped successful the past 10 years mostly owed to user wallets.)

Because of this, mobile’s publication to ecommerce and nonstop effect campaigns has risen dramatically.

Gone are the days erstwhile you didn’t privation to whip retired your recognition paper and punch it into your telephone portion successful public. 

As we borderline person to a imaginable recession, the request to turn immoderate show effort skyrockets. 

It is intelligibly evident that mobile should beryllium isolated from desktop due to the fact that of 2 immense factors: 

• Budgeting.
• Performance. 

(Sorry tablet, but with your marketplace stock contraction since 2019, you get rolled successful with desktop successful my opinion).

Won’t the hunt engines allocate my walk and optimize for performance?

Technically, they tin optimize and allocate walk to a device. 

But, if you’re relying connected the engines to bash what is successful your champion interest, past you’re much doomed than immoderate New York Jets backmost since 2007.

Think of it this way:

An motor volition bid up oregon down by device, erstwhile a bid strategy is successful place, to execute the champion imaginable effect to the rule. 

It whitethorn besides withhold fund from tablet oregon desktop to walk connected mobile. But that whitethorn not beryllium successful your champion interest.

Let’s look astatine an progressive script I person tested connected a pb procreation run utilizing a max click bid strategy. 

We were overly assured astir the tract and creative, truthful we realized optimizing for much postulation would present much leads than optimizing specifically to much conversions.

All devices consolidated:

• $10,000 full spend
  • $3,000 desktop
  • $6,750 mobile
  • $250 tablet
• 4,150 full clicks ($2.41 CPC)
  • 1,150 desktop ($2.61 CPC)
  • 2,900 mobile ($2.32 CPC)
  • 100 tablet ($2.50 CPC)
• 850 leads ($11.64 CPL/20.5% Lead Rate)
  • 403 desktop ($7.44 CPL/35% Lead Rate)
  • 414 mobile ($16.30 CPL/14% Lead Rate)
  • 33 tablet ($7.57 CPL/33% Lead Rate)

We past separated the devices into 2 groups: 

• Desktop and tablet together.
• Mobile connected its own. 

We divided the fund to beryllium 65% mobile and 35% to desktop and tablet:

•  $10,000 full spend
  • $3,750 desktop+tablet
  • $6,250 mobile
• 4,400 full clicks ($2.27 CPC)
  • 1,426 desktop+tablet ($2.63 CPC)
  • 2,974 mobile ($2.10 CPC)
• 945 leads ($10.58 CPL/21.4% Lead Rate)
  • 499 desktop+tablet ($7.51 CPL/35% Lead Rate)
  • 446 mobile ($14.01 CPL/15% Lead Rate)

Both scenarios person the aforesaid bid strategy.

The consolidated mentation was the last 4 weeks of the campaigns, portion the separated mentation was the last 4 weeks of a six-week test. (We threw retired the archetypal 2 weeks for the bid strategy to decently learn.) 

Both clip periods were not successful highest seasons.

The crushed the fund for desktop+tablet was enactment astatine 37.5% alternatively of 32.5% (spend level erstwhile consolidated) was that it was theorized that determination was instrumentality cannibalization connected fund by mobile. Therefore, we elected to springiness it an other $500 to trial that content out.

The result proved a fig of theories:

• Mobile was successful information cannibalizing desktop, starring to less imaginable desktop clicks and, therefore, conversions.
• Mobile CPC was apt skewed upward due to the fact that of the engines’ allocation to desktop and tablet not giving it its existent opportunity.
• Not allowing the devices to interaction 1 different successful the bid strategy oregon the budgeting allowed for a greater measurement of clicks and truthful leads (lead complaint was fundamentally unchanged), but this did thrust down the outgo per lead.

This besides illustrates the value of quality oversight and involution successful bid strategies.

While not utilized successful this test, determination are studies done that amusement the payment of citing the mobile acquisition successful a mobile originative (i.e., “Sign up from your phone”) successful improving CTR and lowering CPC.

How volition this enactment with a debased budget?

Herein lies the existent determination for the advertiser. This attack is feasible if:

• You person a important fund to enactment with truthful that nary run is considered constrained. (This is babelike connected the relationship structure/number of campaigns, and however overmuch regular fund you have.)
• And you already person an knowing of request and walk by device.

Who shouldn’t bash this?

There are arguments to not bash this approach, the astir communal are:

• Smaller budgets, the world is, this whitethorn not beryllium imaginable without causing 1 run to beryllium improperly budgeted.
• If you're blessed with your existent show successful instrumentality consolidation, past support doing what you're doing.
• Lack of resources to negociate much campaigns.

This isn't for everyone, but ne'er regularisation retired the conception of instrumentality segmentation until you've reviewed the data.

Why is instrumentality segmentation much important than SKAG?

Single keyword advertisement groups (or SKAGs) person been a common model for galore years wrong the hunt industry, mostly utilized for nonstop and immoderate operation advertisement groups. You needed a beardown antagonistic crippled to bash it.

But the information of the substance is, SKAGs are present grossly skewed by the "loosening of lucifer types" for the past fewer years. 

The magnitude of clip and effort to enactment unneurotic a coagulated SKAG advertisement radical is apt to nutrient little instrumentality than a coagulated instrumentality segmentation build. 

Blame the engines for that.
