Beware of Conversion Cannibalism

How we allow CTAs to cannibalise on each other.

Does your web design suf­fer from con­ver­sion cannibalism?

Organisations add CTAs fre­quently, hop­ing to increase con­ver­sions. They hope that 1+1=3, but in real­ity, it’s closer to 1+1=0.

Adding more CTAs (call-to-actions) to a single browser view will allow these but­tons and forms to can­ni­bal­ise each oth­er­’s con­ver­sion rates.

I will demon­strate why less is more in web design.

Here we go:

Conversion Cannibalism

Imagine a web page with one but­ton for users to click. Let’s say the but­ton gen­er­ates 10 clicks.

So, what if you add anoth­er but­ton?
Will you now get 10 + 10 clicks?

Typically, no.

In most cases, you won’t even get to keep your ini­tial 10 clicks. You might get 5 clicks in total and thus lose half of your engage­ment by adding anoth­er choice.

This is con­ver­sion cannibalism.

The Paradox of Choice

In 1995, Professor Shena Iyengar from Columbia University launched a mar­ket stall with dif­fer­ent jam fla­vours. When she offered twenty-four options, more people came to the booth. When she only offered six choices, more people con­ver­ted into pay­ing customers.

Our decision-mak­ing pro­cess is com­plex, but research­ers have offered many pos­sible explan­a­tions, such as decision fatigue, ana­lys­is para­lys­is, and buy­er­’s remorse. 1Piasecki, M., & Hanna, S. (2011). A Redefinition of the Paradox of Choice. , 347 – 366. https://​doi​.org/​1​0​.​1​0​0​7​/​978 – 94-007‑0510-4_19

Buttons and forms on a web­site are sub­ject to the para­dox of choice.

Horizontal vs Vertical Design

On the web today, we see a trend where there is white space to both the left and right of but­tons and forms. We also see a trend where more of the same CTAs are stacked from top to bottom.

Why is this a design trend?

The minor­ity who click your content’s call to action (con­tent diver = mov­ing ver­tic­ally) is expo­nen­tially more valu­able than the major­ity who scan and move along (con­tent surfer = mov­ing horizontally).

The stra­tegic pla­cing of CTAs and visu­al ele­ments should, there­fore, be con­sidered when design­ing a web page:

  • Only one CTA per web page. Buttons and forms with dif­fer­ent CTAs com­pete on a web page. One single CTA often con­verts more than sev­er­al CTAs. However, vari­ations of the same CTA can be stacked vertically.
  • Stack visu­al ele­ments ver­tic­ally. When stacked hori­zont­ally on a web page, but­ton and form ele­ments com­pete. Presenting only one but­ton or form per hori­zont­al block would be best.

The Classic Home Page Debate

We must put all these items on our home page because they’re all import­ant to us.”

I often get involved in heated debates on what to include on the home page. If I weigh into the debate that they should remove cer­tain ele­ments, the chances are that someone will get offended. 

Like, “How dare you sug­gest that my work func­tion be removed from our home page?”

The Google Home Page

Take a look at Google’s home page:

Google's home page.
Google’s home page is clean. How is yours?

Now, Google has many products that are argu­ably import­ant to their busi­ness model.

To name a few examples:

  • Google Gmail
  • Google Drive
  • Google Maps
  • Google Chrome
  • Google Earth
  • Google Trends
  • Google Ads
  • Google Adsense
  • Google Analytics
  • Google Scholar

All these Google products are reas­on­ably sig­ni­fic­ant, right? However, they still don’t replace Google’s de facto home page — the Google Search page (designed to be a land­ing page).

It begs the ques­tion:
If Google can keep its home page clean, why can­’t you? 

Small Ask vs Big Ask

The key to an effi­cient home page design is to stop think­ing about what’s “import­ant” and “not important”.

Think instead of how to cre­ate a “yes lad­der” by start­ing with a “small ask” and, through ice­berg pub­lish­ing, work your way up to a “big ask.”

Small ask = a value pro­pos­i­tion that requires little effort and resources for a pro­spect to accept. It works best when the ask offers a swift, hassle-free solu­tion for an urgent pain point.

Big ask = a value pro­pos­i­tion that requires high engage­ment and a sub­stan­tial trans­ac­tion by the pro­spect. It works best when mutu­al under­stand­ing and trust are thor­oughly established.

By pri­or­it­ising a small ask on the home page design, you increase the like­li­hood of build­ing such a “yes lad­der” by gently prim­ing your user to “yes” over time.

The Engagement Pyramid

The 1% rule of online engage­ment was mainly an urb­an legend on the inter­net. However, a peer-reviewed paper from 2014 con­firmed the 1% rule of thumb. 2Trevor van Mierlo. (2014). The 1% Rule in Four Digital Health Social Networks: An Observational Study. Journal of Medical Internet Research, 16(2), e33 – e33. … Continue read­ing

Active pub­lics dis­trib­ute them­selves in a way proven sci­en­tific­ally by soci­olo­gists — long before the inter­net and social media emerged. 

The engage­ment pyr­am­id divides pub­lics into three dis­tinct groups:

  • Creators (1%)
  • Contributors (9%)
  • Lurkers (90%)

When study­ing inter­net for­ums spe­cific­ally, it’s not uncom­mon to find that 90% of users have nev­er pos­ted (lurk­ers), 9% are adding only to exist­ing top­ics and threads (con­trib­ut­ors), and 1% are act­ively start­ing new sub­jects and threads (cre­at­ors).

The engage­ment pyr­am­id is some­times called the 1% rule or the 90−9−1 principle.

The 90−9−1 prin­ciple and Zipf’s Law both effect­ively clas­si­fy mem­bers in online sup­port groups, with the Zipf dis­tri­bu­tion account­ing for 98.6% of the vari­ance.”

Priority: The Small Ask

The choice of what to put on the front page isn’t related to what’s neces­sary or not neces­sary. Instead, it should be regarded only as a point of entry into your brand’s universe.

Instead of cram­ming everything into one front page, your busi­ness could util­ise mul­tiple high-con­vert­ing land­ing pages, a strategy I call ice­berg pub­lish­ing, where many hid­den dir­ect land­ing pages are beneath the site’s surface.

By mak­ing a small ask (your email address in exchange for some­thing valu­able to you) instead of a big ask (invest in hir­ing me as an advisor), I can cap­ture and nur­ture trust­ing rela­tion­ships over time, slowly mov­ing pro­spects from 9% to 1%. 

Looking back at the Google example, one could say they use mul­tiple front pages. If we look at Google Drive’s “front page,” we can see the same strategy: just one mes­sage and one call-to-action above the fold. It works because it’s crys­tal clear:

More and more con­ver­sion experts argue that most pages with­in a web­site’s struc­ture should be land­ing pages. Landing pages are access­ible for search engines to drive rel­ev­ant traffic since they’re stripped of unne­ces­sary content.
