01 Customer Demand SpursTrends and Tactics Driving Marketing ROI6Full-Funnel MarketingCustomer experience has become a guidinglight for brands, with 73% of customers sayingone extraordinary experience raises theirexpectations of other companies.* The to-dolist is long for today’s marketers, but with 71%of customers now expecting real-timecommunication,* marketers are focusing theirefforts accordingly.Second only to engaging customers in realtime, optimizing the marketing mix for bestreturn is a top marketing objective, therebymaking solid attribution an imperative. It’sperhaps no coincidence that modernizing toolsand technology — such as those that betteranalyze customer journeys — rounds out the topthree marketing priorities.The value of attribution is underscored bythe fact that top marketing teams — thosewho are higher performers — are particularlyfocused on it.High Performers vs. Underperformers2.1xmore likely to say improvingmeasurement/attribution is a high priority(53% vs. 25%)Real-Time Engagement Tops Marketers’ Many PrioritiesMarketing PrioritiesEngaging with customers in real time55%Optimizing the marketing mix forbest return49%40%Modernizing tools and technologies48%41%Creating a shared, single view of thecustomer across business units47%41%Unifying customer data sources47%41%Complying with regional and/or localprivacy regulations46%39%Investing in and effectively usingnew technology45%40%Adopting or refining a customerjourney strategy44%41%Improving measurement/attribution39%46%Consolidating tools and technologies40%45%Balancing personalization with privacyRevamping organizational structuresand processes40%“State of the Connected Customer,” Salesforce Research, June 2019.42%35%High priority*34%46%Moderate prioritySalesforce Research

01 Customer Demand SpursTrends and Tactics Driving Marketing ROI9Full-Funnel MarketingMost of the top metrics for overall marketingsuccess are simple and channel- or leadfocused. However, during specific stages ofthe customer lifecycle, more marketers findsuccess using advanced metrics like revenuegrowth and LTV.Interestingly, the top metrics marketers use toevaluate brand building are traditionallyassociated with customer advocacy — such asnet promoter score (NPS) and customersatisfaction score (CSAT). Their power at thebrand-building stage suggests today’s customerjourney may be better understood as a cyclethan a linear trajectory. It also exemplifies justhow much power today’s customers have, inthat they can make or break brands based onthe experiences provided.Further down the funnel, marketers measureupselling with traditional sales metrics, as wellas by examining the result of specific marketingtactics on the process. Similarly, to gaugecustomer advocacy, marketers turn totraditional metrics like customer referral rates,while also monitoring social channels for thequality and quantity of public feedback.Marketers Lean on Advanced, Cross-Functional Metricsto Evaluate Customer Journey StagesPrimary Success Metrics for Each Stage of the Customer Journey*#1#2#3#4Overall MarketingProgramMarketingqualified leadsMarketing returnon investment(MROI)Sales effectivenessMarketing tacticROIBrand BuildingCustomersatisfactionRevenue growthMarketingqualified leadsSales effectivenessLead GenerationMarketingqualified leadsCost per lead (CPL)Sales effectivenessWeb traffic ion ratesCustomeracquisition cost(CAC)CustomersatisfactionCustomer referralrates/volumeUpsellingSales effectivenessRevenue growthMarketing tacticROICustomersatisfactionCustomer RetentionCustomerretention ratesCustomersatisfactionLifetime customervalue (LTV)Customer referralrates/volumeCustomer AdvocacyCustomersatisfactionCustomer referralrates/volumeSocial analyticsLifetime customervalue (LTV)*Base: Respondents who currently track the corresponding metric.Salesforce Research

SPOTLIGHTTrends and Tactics Driving Marketing ROI10The Data Source Count Is GrowingCustomer data sources — from first-partywebsite analytics to syndicated third-partydatabases — have been increasing in numberyear-over-year for companies of all sizes.Over a three-year period,* the pace of datasource growth for small and mediumbusinesses (SMBs) has mirrored that ofenterprises, with the median count ofenterprise data sources consistently twicethat of SMBs. However, while data sourcegrowth has slowed over the past year forenterprises and SMBs, it is picking up formid-market companies.Unifying customer data sources is at least amoderate priority for 88% of marketers acrossthe board. Enterprise marketers, however, aremore likely than those at SMBs and mid-marketcompanies to call it a high priority (54% vs.45% and 46%, respectively).Data Sources Are Proliferating – No Matter the Company SizeMedian Number of Data Sources Used by Marketing OrganizationsSMB (21–100 employees)20172018610122019**Mid-market (101–3,500 employees)201720181012152019**Enterprise (3,501 employees)201720182019***2019 data comes from marketers’ projections.**Projected number of data sources.122024Salesforce Research

02 Unifying Data Sources Unlocks Richer InsightsA lot goes into improving measurement andattribution, and 34% of marketers say they’rechallenged by the process. Measurement ofcomplex metrics — like revenue growth —benefits from both fluid cross-teamcollaboration and data source integration.The number of customer data sources used bymarketers has been climbing, but for manymarketers, it can’t be accessed in a singlelocation. Currently, only 47% have acompletely unified view of customer data.High-performing marketing teams aremore likely than underperformers to have acompletely unified view of customer datasources. They are also more likely tocompletely integrate marketing tools withother business systems.High Performers vs. Underperformers1.6xmore likely to have a completelyunified view of customer data sources(55% vs. 35%)Trends and Tactics Driving Marketing ROI11Top Marketers Take System Integration SeriouslyMarketers Who Have Completely Integrated Their Technologywith the Following60% Customer service systems52%CRM, ERP, or other salessystems41%Advertising technology(e.g., ad servers, DSPs, SSPs, etc.)61%41%53% Analytics systems54%34%36%24%High performersHigh Performers vs.Underperformers52%42%71%68%64%53%Moderate performers1.7xmore likely2.0xmore likely1.8xmore likely2.2xmore likelyUnderperformersSalesforce Research

02 Unifying Data Sources Unlocks Richer InsightsNever mind the days when measuringmarketing effectiveness was largely guesswork,or based on glimpses into simple top-of-funneldata like opens and impressions. Today’smethods of measuring success are rapidlygrowing in sophistication.While simpler, singular-focused measurementtechnologies like web analytics and ad channelplatforms are used by many marketers, moresophisticated technologies like DMPs andmarketing analytics platforms are close behind.These more advanced tools unlock insightsgathered across multiple data sources,providing a “forest for the trees” view. Seventyone percent of marketers with a DMP use it formarketing analytics and advertisingperformance measurement — for example,through custom dashboards.Already, four in 10 marketers are usingnewer methods of measurement based ondata science and attribution modeling.Trends and Tactics Driving Marketing ROI12Marketers Leverage Platforms to Consolidate Data SourcesMarketers Using the Following Technologies/Methods to Measure SuccessWeb analytics59%Marketing/ad channel platforms55%Data management platforms (DMP)54%Marketing analytics/measurement platforms52%Social marketing platforms46%Data science-driven methods(e.g., algorithm-based methods)42%Marketing attribution modeling (e.g.,marketing mix modeling, multitouch attribution)41%Mobile measurement platforms36%Homegrown solutions25%High Performers vs. Underperformers1.4xmore likely to say traditionalapproaches to marketing measurement areno longer effectiveSalesforce Research

SPOTLIGHTTrends and Tactics Driving Marketing ROI13Channel Effectiveness Varies byBusiness TypeMarketing channel strategy is not one-size-fitsall. Customer communities are highly valued byall company types when it comes to customeracquisition and retention. However, channelROI diverges for B2B, B2B2C, and B2Celsewhere in the customer journey.Social advertising is one of the top customeracquisition channels for B2C and B2B2Ccompanies, but it doesn’t rank as highly for B2Bmarketers, whose sales are less impulse-driven.Meanwhile, affiliate marketing shows stronglyfor both B2B and B2B2C companies, whosesales models often rely heavily on partnershipsto expand reach.The B2C marketers who use the internet ofthings (IoT) find it particularly valuable forupselling. This reflects the IoT’s ability to blenddigital and physical worlds — a concern forretailers operating online and brick-and-mortarstorefronts.Down the funnel, email is widely reported as ahigh-performing channel. Both B2B and B2Cbuyers say email is their most preferred channelto interact with brands,* a finding consistentwith the channel’s strong performance acrossbusiness types for upselling and retention.*“State of the Connected Customer,” Salesforce Research, June 2019.Different Businesses Favor Different ChannelsHighest ROI Channels Across Key Stages of the Customer Journey by Business n**B2BB2CB2B2CCustomer communitiesCustomer communitiesCustomer communitiesWebsiteSocial advertisingSocial advertisingEmail marketingWebsiteAffiliate marketingAffiliate marketingSocial publishingWebsiteWebsiteWebsiteWebsiteEmailSocial advertisingSocial advertisingAffiliate marketingEmailAffiliate marketingSocial advertisingIoT/connected devicesEmailCustomer communitiesCustomer communitiesCustomer ial advertisingMobile appSocial advertisingBase: Marketers currently using the indicated channel.Salesforce Research
