The Most Important KPI For A Performance Marketer

Many performance marketers continue to consider click-through rate (CTR) as a key performance indicator of their search campaigns’ effectiveness and evolve their PPC optimization strategy around that.
At the end of the day, what matters most is achieving the best ROI given your business objectives and budget, and you might optimize directly to CTR or ROI or a combination of success metrics to achieve that.
In order to have the best optimization strategy for your SEM campaigns, it is important to understand and quantify the influencers of ROI.

The Two Extreme Optimization Strategies

There are two types of strategies performance marketers consistently use as their campaign optimization strategy:
1)    Optimizing To A CTR Goal
One of the main factors influencing Quality Score (QS) is CTR, which affects your cost-per-click (CPC) and in turn affects your ROI. An increase in QS due to a boost in CTR would lower CPC and improve ROI.
CTR optimization
2)  Optimizing To An ROI Goal (Revenue-Per-Click & Cost-Per-Click)
Direct optimization to revenue or a conversion metric is a common strategy amongst performance marketers. Making sure an intelligent bid management is in use will be crucial to your campaign’s success.

While perhaps no marketer purely optimizes to CTR or ROI, they tend to skew towards one of these camps. Each method has its pros and cons. A CTR strategy will get you more clicks but does not guarantee the highest ROI. A purely ROI approach will get you the highest ROI but you potentially lose out on customers early in the sales funnel who might eventually convert.

ROI Breakdown

ROI equals Revenue-Per-Click (RPC) over Cost-Per-Click (CPC). Data analyzed from over two dozen advertisers using econometric methods (a simplified version of the equation is shown below) shows that 34% of ROI is influenced by RPC and 66% by CPC.
Bid management is by far the most important influencer of ROI. Forty-nine percent (49%) of ROI is influenced by bid management, 13% by other factors (i.e., marketplace, seasonality, etc.), and 4% by CTR. The data show the importance of having an intelligent bid management strategy in place for your SEM campaigns. But, does this mean a CTR maximizing strategy is a wasted effort?

A Deeper Dive Into The Relationship Between ROI & CTR

Previous studies have looked at the relationship between CTR & ROI by purely relying on correlations. A correlation analysis alone cannot determine the effects of CTR on ROI, and a more robust statistical technique is required to answer that question. These techniques enable us to control for all the factors that can potentially influence ROI.
From the chart below, we do see a relationship between the CTR & ROI — but not a very strong one.
SCATTERS

Applying statistical modeling techniques will allow us to quantify any statistically significant relationship between the two if it exists.
In this model, I control for position, CPC, industry, and bid management differences across the different advertisers in the data in addition to CTR.
The results show that there is a statistically significant relationship between CTR and ROI; but in terms of impact, it’s quite small. For a 10% increase in CTR, expect to see a 1.2% increase in ROI. This means that if you increase your CTR from 10% to 11% for a campaign with an average ROI of $5, the ROI will increase to $5.06 due to the improvements made in CTR.

Key Takeaways For Performance Marketers

  • Campaign managers should utilize both strategies above in optimizing their campaigns; main focus should be on ROI but do not completely ignore CTR
  • 49% of ROI is influenced by bid management; intelligent bidding is integral to a campaign’s success
  • CTR does have a small but statistically significant impact on ROI; a 10% change in CTR affects ROI by 1.2%

In Summary

Focus on optimizing your SEM campaigns for ROI but keep an eye on CTR. There is no need to purely optimize to CTR as it influences only 4% of ROI; but, it is important to account for it in your longer term strategy and make sure healthy CTR rates are met and maintained.
Intelligent bid management heavily influences ROI and is absolutely necessary to ensure your ROI goals are met.

Quality Score vs Page Rank

Is Quality Score in PPC Adwords (or Yahoo Index in Yahoo Search) simillar to Page Rank in SEO… Lets find out!
The article includes points of similarity on two important Algorithm metrics in Search Engine Marketing World (PPC + SEO). The list is not final as there is more, which needs to be included, but I’ve tried to highlight dots that could be a part of our initial point of understanding / learning / conversation.

CPCs by Search Engine Q2 Search Agency

The Impact Of Enhanced Campaigns 

While reports from RKG and Covario concluded that enhanced campaigns have had little impact so far on CPCs, The Search Agency finds otherwise. The report says, “The rise in marketplace competition caused a spike in CPCs during Q2″.
The report also suggests that enhanced campaigns played a role in the relative decline in clicks QoQ compared to impressions: Declining CTR “may indicate a shift in matching or query mapping changes at the search engine level.” Google impressions rose 21.4 percent while clicks fell off 7.1 percent QoQ.
CTR dropped sharply in Google from last quarter — from 3.46 percent to 2.66 percent. However, it looks more like there was a spike in Q1.
Google Bing CTR Q2 Search Agency
Though less dramatic, Bing also saw click declines. Bing impressions rose 15.6 percent while clicks dropped 4.1 percent QoQ. Bing also saw an increase in CTR in Q1 and dropped back closer to Q4 levels last quarter.
Overall CTRs fell across devices in Q2. Desktop was off 22.6 percent QoQ, though just 3.9 percent YoY. Smartphone CTR fell 18.6 percent QoQ and 16.5 percent YoY. And Tablets saw the biggest QoQ drop, falling 21.1 percent, and 15.1 percent YoY.

Smartphone share of spend has risen 70.4 percent YoY and 12 percent QoQ. While tablets have increased their share of spend by 74.7 percent YOY and 4.2 percent QoQ.

Mobile Efficiencies Still High On Bing

While Google CPC efficiencies compared to desktop are falling for both smartphones (11.3 percent down from 14.1 percent in Q1) and tablets (now 1.7 percent higher than desktops), there are still sizeable discounts on Bing. Bing smartphone CPCs were 28.3 percent lower than desktop in Q2 (way up from 16 percent in Q1), and Bing tablet CPCs are off 7.7 percent compared to desktops. That’s up from 5.2 percent in Q1.
The Search Agency sees device adoption on Bing continuing to grow and suggests there is a particularly strong opportunity to add tablet campaign on Bing. Overall they suggest adopting a consistent mobile strategy to better understand consumer search behavior and increasing clickshare on tablets and smartphones.
