Effectiveness of Search Engine Marketing Channels

Summary: Digital ads will make up 50% of all ad spending by the end of 2018. This article summarizes an empirical study that ranked digital advertising channels by their effectiveness on sales. Natural SEO and PPC came in first and second for sales effectiveness.

Digital ad spending passed TV for the first time in 2017 (Kafka & Molla 2017). In fact, digital ads will make up 50% of all ad spending by the end of 2018, faster than expected (Berwitz 2018). With the growing penetration of digital advertising, it's important to use the most effective online advertising channels. This article summarizes an empirical study that ranked digital advertising channels by their effectiveness on sales.

An Empirical Study of Digital Marketing and its Elements

In a 2017 study, Assistant Professor Reena Malik set out to quantify the effectiveness of the various digital marketing channels on sales (Malik 2017). Using surveys and data from 70 marketing companies Dr. Malik correlated seven digital advertising channels (SEO, PPC, e-mail, mobile, pop-ups, social media, and affiliate marketing) with sales (see Figure 1).

The Effectiveness of SEM Channels on Sales

Figure 1: The Effectiveness of SEM Channels on Sales

Professor Malik found that natural Search Engine Optimization (SEO) was the most effective SEM channel to increase sales (0.962 correlation). Pay Per Click came in second at 0.884, followed by mobile advertising (0.860), e-mail ads (0.823) and social media (0.742). Showing lower correlation were affiliate marketing (0.597) and pop-up ads (0.576).

Discussion and Caveats

This study confirms what many SEM companies have found, that natural SEO and PPC are the most effective ways to increase sales. What the study does not address is the cost effectiveness of each channel in driving leads. We'll address this ROI aspect in a future tweak.

Conclusion

This study found that natural SEO is the most effective way to increase sales online. PPC, mobile, e-mail, and social media advertising followed in increasing sales effectiveness. While still correlating with increasing sales, affiliate marketing and pop-up advertising were the least effective SEM channels in increasing sales.
