1 Skills Employers Look for in Digital Marketing Roles

1.1 Core Digital Marketing Skills

Employers expect a strong grounding in marketing principles + digital execution:

  • SEO/SEM: Keyword research, on-page SEO, technical SEO, Google Ads.

  • Content Marketing: Strategy, writing, optimizing for engagement & conversions.

  • Social Media Marketing: Paid/organic campaigns across platforms, audience targeting.

  • Email Marketing & CRM: Segmentation, A/B testing, lifecycle campaigns.

  • Performance Marketing: Paid search, display, social ads, ROI optimization.

  • Marketing Automation: HubSpot, Salesforce Marketing Cloud, Marketo, etc.

  • Campaign Analytics: Attribution models, funnel analysis, ROI tracking.

1.2 Analytics & Data Skills

This is where R, Python, SQL, and BI tools give candidates a big edge:

  • Data Wrangling & Analysis: SQL (databases), R/Python for data cleaning and modeling.

  • Web & Campaign Analytics: Google Analytics 4 (GA4), Tag Manager, Looker Studio.

  • Marketing Mix Modeling (MMM) & Attribution: Understanding how channels drive results.

  • A/B Testing & Experimentation: Experimental design, statistical analysis.

  • Customer Analytics: Segmentation, lifetime value prediction, churn modeling.

  • Forecasting: Time-series forecasting of sales, demand, or campaign KPIs.

  • Dashboarding & Visualization: Tableau, Power BI, R Shiny, or Quarto for storytelling.

  • Big Data Tools (nice-to-have): Working with APIs, warehouses (BigQuery, Snowflake), Arrow/duckdb for large datasets.

1.3 Tech & Emerging Tools

  • Quarto / RMarkdown: Reproducible reports & documentation.

  • Machine Learning Basics: Predictive modeling, recommendation systems (entry-level knowledge is often enough for marketing roles).

  • AI for Marketing: Understanding how GenAI is applied to content creation, personalization, and customer insights.

1.4 Business & Soft Skills

This often makes or breaks candidates:

  • Storytelling with Data: Translating analytics into business recommendations.

  • Project Management: Agile workflows, cross-team collaboration.

  • Communication: Explaining technical insights to non-technical stakeholders.

  • Problem Solving: Turning ambiguous marketing challenges into testable, data-driven solutions.

  • Commercial Awareness: Understanding ROI, CAC, CLV, and KPIs that matter to business leaders.

1.5 Skill Bundles by Role Type

To help your students target different flavors of digital marketing roles:

  • Digital Marketing Analyst / Data Scientist
    • SQL, R/Python, A/B testing, MMM, GA4, dashboarding.
  • Performance Marketing Specialist
    • Paid ads, GA4, attribution, campaign optimization, Excel/SQL.
  • Marketing Automation / CRM Specialist
    • Email automation tools, segmentation, lifecycle marketing, A/B testing.
  • Growth Marketer
    • Blend of analytics + campaign execution + experimentation mindset.
  • Digital Marketing Manager (strategic)
    • Team leadership, vendor management, high-level analytics (dashboards, ROI tracking).
👉 Bottom Line:

Employers want marketers who can work with data. Even if they’re not “full data scientists,” knowing SQL + R/Python basics + GA4 + A/B testing gives them a big competitive edge in digital marketing roles. Pair that with strong storytelling and business impact communication, and they’re highly employable.

1.6 Social Media Marketing Managers & Content Creators

1.6.1 Core skills they must have:

  • Platform expertise: Meta, TikTok, LinkedIn, YouTube, X (ads + organic).

  • Content strategy: Matching brand voice with platform audience.

  • Creative skills: Copywriting, design tools (Canva, Adobe suite), short-form video.

  • Community management: Engaging audiences, managing comments, brand reputation.

  • Campaign performance: Reading dashboards (reach, engagement, CTR, conversions).

1.6.2 Data skills (nice-to-have, but not the core):

  • Basic analytics literacy:

    • Understanding metrics (CTR, engagement rate, conversion rate, ROAS).

    • A/B testing creatives (e.g., which ad copy/video works better).

  • Intermediate (optional, career-boosting):

    • SQL/R/Python not essential, but helpful if they want to grow into a broader analytics or digital marketing manager role.

    • Knowing how to pull performance data from APIs (e.g., Meta Ads, Google Ads) is a differentiator, but not expected for most content roles.

👉 Bottom line:

SMMs and content creators don’t need deep DBI/dbplyr/Arrow-level skills. They need to be data-aware — capable of interpreting dashboards and making creative/strategy decisions from them.

1.7 Digital Marketing Managers

1.7.1 Core expectations:

  • Strategic oversight of campaigns across channels (search, social, display, email, web).

  • Budget management: Allocating spend across channels for ROI.

  • Team coordination: Overseeing content, social, analytics, and performance specialists.

  • Vendor/agency management: Communicating expectations and results.

1.7.2 Data skills (increasingly important):

  • Definitely needed:

    • Comfort with dashboards (GA4, Looker Studio, Tableau, Power BI).

    • Ability to interpret attribution reports (which channels drive conversions).

    • Understanding MMM outputs or campaign lift studies (even if they don’t build the models).

    • Running/overseeing A/B tests (e.g., subject lines, ad targeting).

  • Not always required:

    • Hands-on SQL/R/Python isn’t required in every company — but managers who can at least query a database or validate results have a strong edge.

    • In larger organizations, they’ll work with analysts who do the heavy lifting.

    • In startups/lean teams, managers often do both strategy + basic analytics, so SQL/Excel may be expected.

Tip

👉 Bottom line:

Digital Marketing Managers must be data-literate (able to interpret and act on analytics). They don’t always need to code models themselves, but they need to manage data-driven decision-making. If they aspire to higher-level performance or growth roles, learning SQL and analytics basics is a significant advantage.

1.8 Practical Advice for Students

  • Content/Social-focused careers → Prioritize creative skills, platform mastery, and basic analytics literacy.

  • Managerial/strategic careers → Prioritize data literacy and decision-making with data. Hands-on coding isn’t always mandatory, but understanding the outputs of analytics (MMM, attribution, segmentation) is critical.

👉 Do They Need Analytics?

  • Social media managers & content creators don’t need deep data science skills — dashboards and campaign analytics literacy are enough.

  • Digital marketing managers do need stronger data skills (not necessarily coding, but strong analytics interpretation). Those who can bridge creativity + analytics are the ones who move up fastest.

4 Marketing Analysts and Marketing Data Scientists: Skills and Knowledge

4.1 Career Preparations for Marketing Analytics Career

Data science jobs tailored for marketing is different from regular data science jobs or business analytics. So, again, I consulted GPT 5. My MS in Digital Marketing students asked me if they will be ready for job market as marketing data scientist if they use R and don’t use Python. What advice would you give them?

4.1.1 R is absolutely a marketable skill, but Python often gives an edge

  • R strengths: It’s fantastic for statistics, econometrics, experimental design, marketing mix modeling, and survey data analysis—all things marketing analysts and data scientists need. Many marketing and social science–oriented companies (consultancies, CPG, ad-tech, agencies) rely on R.

  • Python strengths: It dominates in machine learning engineering, AI, data pipelines, and production-level work. If the job involves deploying models at scale or working closely with engineers, Python is usually the standard.

4.1.2 Employers care about the core skills

  • Knowing how to design experiments, analyze consumer data, build predictive models, interpret insights, and communicate recommendations matters more than the specific tool.

  • If you can demonstrate strong knowledge in data wrangling, modeling, visualization, and storytelling, you’re employable—whether in R, Python, or even SQL + BI tools.

4.1.3 Bridging R to the job market

  • For analytics-heavy roles (marketing research, econometrics, MMM, A/B testing, segmentation, customer insights): R is more than enough.

  • For ML/AI-heavy roles (recommendation systems, NLP on consumer text, computer vision for ad content): You’ll likely need Python.

4.1.4 What I’d recommend to them

  • Get excellent at R first. Become fluent in tidyverse, modeling packages, and reporting (e.g., RMarkdown/Shiny).

  • Pick up Python basics along the way (especially pandas, scikit-learn, maybe TensorFlow/PyTorch if they’re ambitious). Even if they’re not fluent, just showing “working knowledge” reduces employer concerns.

  • Always highlight transferable skills. Frame your résumé and interviews around what you can do with data (segmentation, predictive models, campaign optimization), not just which software you use.

👉 So the bottom line to students would be:

Yes, you can be job-ready with just R for many marketing analytics and data science roles. But if you want to maximize opportunities—especially in ML-heavy or tech-company contexts—adding at least some Python competency will make you more competitive.

4.2 Marketing Data Scientist Job-Readiness Roadmap

4.2.1 Core Analytics & Marketing Knowledge

  • Be able to frame business problems as data problems

  • A/B testing & experimental design (campaign testing, website optimization)

    • pandas, numpy, scikit-learn for predictive modeling

    • Optional: tensorflow/pytorch for deep learning if going ML-heavy

  • BI Tools: Tableau or PowerBI (business-facing dashboards)

4.2.3 Math & Stats Foundation

  • Regression (linear, logistic, regularized)

  • Hypothesis testing, ANOVA, chi-square

  • Bayesian inference (useful for MMM & A/B testing)

  • Time series forecasting

4.2.4 Business & Storytelling Skills

  • Turning statistical outputs into marketing recommendations

  • Visualization for non-technical stakeholders

  • Writing executive-friendly reports (e.g., “Campaign X lifted ROI by 12%”)

  • Communicating uncertainty and trade-offs

4.2.5 Portfolio Project Ideas (Show Employers!)

Encourage students to publish on GitHub + LinkedIn:

  1. Marketing Mix Model (MMM) on simulated data — estimate ROI of channels

  2. Customer Segmentation with clustering (K-means / hierarchical / mixture models)

  3. A/B Test Simulation — show how to design, analyze, and interpret results

  4. Customer Churn Prediction — build a classification model from CRM data

  5. Sentiment Analysis on customer reviews or social media (Python-friendly add-on)

  6. Interactive Dashboard (R Shiny or Tableau) for campaign performance

4.2.6 Job Search Positioning

  • Frame yourself as: “I use data to optimize marketing decisions and drive ROI.”

  • Tailor résumé to highlight:

    • Tools: R, SQL, some Python

    • Skills: A/B testing, MMM, segmentation, forecasting, churn prediction

    • Communication: dashboards, storytelling

4.2.7 Final Advice

  • Yes, R is enough to get into analytics-heavy roles.

  • Python basics unlock ML/AI-heavy roles (tech firms, ad-tech, recommendation systems).

  • Employers don’t hire tools—they hire problem solvers who can generate insights from data.

4.3 What is Positron?

Positron is a free, next-generation data science IDE from Posit (formerly RStudio) that supports both Python and R natively—it’s designed for polyglot workflows. It’s built on the open-source Code OSS (the foundation of VS Code) and brings a modern, extensible environment tailored for data work (isabel.quarto.pub+12Posit+12jumpingrivers.com+12.)

  • Integrated Data App Workflow: Launch and debug Shiny, Streamlit, Dash, or FastAPI apps with a single click (Posit+1)

4.4 How Does It Compare to RStudio for Data Warehouse Integration?

RStudio remains a highly stable and familiar environment for R work, especially in statistical modeling and reproducible reporting with R Markdown or Quarto (Posit+14positron.posit.co+14Wikipedia+14). However, when it comes to interfacing with data warehouses—typically SQL-heavy work—Positron offers distinct advantages:

4.4.1 Advantages of Positron:

  1. Built-In SQL Integration: The Database Connection Pane lets users connect to and query SQL data sources right inside the IDE, making data-access streamlined.

  2. Polyglot Workflow: For teams or students who may use both R and Python for ETL, modeling, or automation, Positron lets them do so in one session—no context-switching needed.

  3. Modern, Customizable UI: Being based on VS Code, Positron supports a wide ecosystem of extensions, customizable layout, and flexible workflows (denniseirorere.com+14drmowinckels.io+14Occasional Divergences+14Links to an external site.Occasional Divergences+1.)

4.4.2 Things to Keep in Mind:

  • Beta Maturity: Positron is still relatively new and under active development. Some features familiar from RStudio—like inline output in Quarto documents, workspace autosave on restart, history pane, and RStudio Add-ins—are not yet fully implemented (positron.posit.co+2Wikipedia+2)

  • Learning Curve: Switching from RStudio may take some onboarding time, especially for users accustomed to its tightly integrated interface (jumpingrivers.com)

  • Foundation: RStudio continues to be maintained with a focus on stability, especially for R-heavy workflows. Positron is additive, not a replacement (Posit;positron.posit.co)

4.5 Judgment Call: Is Positron Better for Data Warehouse Workflows?

Yes—especially for workflows involving SQL or dual-language environments. Here’s why:

  • The built-in SQL pane and query tools make accessing warehouse data naturally part of the coding workflow.

  • Students can seamlessly move between R and Python, which many real-world jobs require.

  • The VS Code-based engine makes Positron extensible, customizable, and future-facing.

That said, if the student is focused primarily on R and relies heavily on RMarkdown, Addins, or a very streamlined R-focused workflow, RStudio may still feel more polished.

4.6 Recommendation for Marketing Data Science Tools

  • For SQL-heavy, polyglot, or app-deployment workflows: Encourage them to experiment with Positron. Its features align well with modern data engineering and analytics workflows.

  • For R-focused, academic, or reproducibility-heavy tasks: RStudio remains excellent and highly reliable—especially for teaching foundations in R.

4.6.1 What to install (minimum viable setup)

  1. R in VS Code

  • Extension: “R” (REditorSupport) — consoles, data viewer, plots pane, workspace browser, debugging, Rmd support. (Visual Studio Marketplace;Visual Studio Code;GitHub.)

  • Helpful bits:

    • languageserver for IDE features (autocomplete, linting). (jozef.io)

    • httpgd for a great plot viewer (enable “R: Plot: Use httpgd”). Note: currently installed from GitHub. (Stack Overflow)

  1. Quarto
  1. Python

4.6.2 Connecting to data warehouses (three good paths)

A. Pure SQL inside VS Code

B. R + DBI/odbc from your code

C. Python from your code

4.6.3 VS Code vs. Positron vs. RStudio (for your use case)

  • VS Code: Most mature polyglot environment today; deep SQL tooling; constant releases; huge extension ecosystem (including Quarto). Great when students mix R, Python, and warehouse SQL. Microsoft for DevelopersLinks to an external site.

  • Positron: Promising R+Python IDE from Posit with data/variable explorer and SQL pane, but still maturing; some RStudio niceties aren’t fully there yet. If you need “ready today” for warehousing, VS Code wins on stability and breadth. (Context: Positron pages highlight active development and gaps vs RStudio.) QuartoLinks to an external site.

  • RStudio: Still superb for R-first teaching (R Markdown/Quarto, tidyverse, Shiny) but not as strong for multi-language + warehouse dev as VS Code’s ecosystem.

4.6.4 Quick-start checklist for your class

4.6.5 Bottom line

If Positron feels a bit early for you right now, VS Code is the best “bridge”: rock-solid for R + Quarto + Python and excellent for data-warehouse workflows via SQLTools/warehouse extensions or via DBI/odbc inside your code. It’s a great environment to standardize on for your cohort this year.

7 SQL (Structured Query Language )

7.1 Introduction: The Role of SQL in Digital Marketing and Analytics

In today’s data-driven marketing landscape, the ability to access, understand, and analyze data directly is a defining skill for success. Among the many tools available, Structured Query Language (SQL) stands out as the universal language of data. SQL allows professionals to interact directly with databases — retrieving customer, campaign, and performance data that drive informed marketing decisions.

While SQL originated as a technical tool for database administrators and data engineers, it has become indispensable across many digital marketing roles.

  • Digital marketing analysts use SQL to extract and clean data from Google Analytics, CRM, and advertising platforms.

  • Marketing data scientists rely on SQL to join and aggregate large datasets before modeling or visualization.

  • Database marketing specialists use SQL to manage and segment customer lists for targeted campaigns.

  • Even digital marketing managers increasingly benefit from understanding SQL to ask better questions and interpret analytics outputs more effectively.

The rise of cloud-based data warehouses like Google BigQuery, Snowflake, and Amazon Redshift has made SQL skills even more valuable. These platforms use SQL as their core query language, allowing marketers to explore millions of records quickly — from customer purchase behavior to campaign ROI — without needing advanced programming.

This study guide provides a structured approach to learning Standard SQL (ANSI-compliant), focusing on how it applies to marketing and digital analytics contexts. You will learn how to:

  • Query and manipulate marketing data efficiently.

  • Perform audience segmentation and campaign performance analysis.

  • Combine SQL with tools like R or Python for deeper insights.

  • Prepare for data-driven roles such as Digital Marketing Analyst, Marketing Data Scientist, and Database Marketing Specialist.

By mastering SQL, digital marketers can go beyond dashboards and pre-built reports — they can uncover insights hidden in raw data, ask better questions, and make evidence-based decisions that drive measurable business outcomes.

7.5 Using SQL within R

7.5.1 Introduction: Using SQL Within R

In modern marketing analytics and data science, professionals often need to work with data stored in large, external databases or cloud data warehouses such as Google BigQuery, Snowflake, or PostgreSQL. While these systems use SQL for querying, analysts and data scientists frequently prefer to analyze, visualize, and model data in R.

The ability to use SQL within R bridges these two worlds — combining the efficiency and scalability of SQL databases with the flexibility and analytical power of R. This integrated approach allows analysts to query large datasets directly from R without fully loading them into memory, transforming R into a front-end interface for high-performance, database-backed analytics.

7.5.2 Who Should Consider This Approach

This method is particularly valuable for:

  • Marketing analysts and data scientists who work with large datasets (ad impressions, web logs, customer transactions) that exceed local memory limits.

  • Database marketing specialists who need to query and segment customer data efficiently while applying statistical or predictive models in R.

  • Researchers or graduate students who want to practice SQL and database handling within an R-centric workflow.

  • Organizations that use R for analytics but store their data in relational systems like BigQuery, PostgreSQL, or DuckDB.

In short, anyone who uses R as their main analysis environment but needs to pull, join, or filter data from databases can benefit from learning SQL within R.

7.5.3 Key Benefits

Benefit Explanation
Efficiency and Scalability Query only the data you need from large databases, saving time and system memory.
Seamless Integration Combine SQL queries with R packages for visualization, modeling, or reporting (e.g., ggplot2, tidymodels, Quarto).
Familiar Syntax Use dplyr verbs (e.g., filter(), mutate(), summarize()) that automatically translate into SQL — no need to rewrite code.
Performance Optimization Packages like Arrow and DuckDB handle large datasets efficiently, even beyond RAM limits.
Reproducibility Keep SQL queries embedded within R scripts or notebooks for transparent, documented workflows.

7.5.4 Potential Limitations

Limitation Mitigation or Consideration
Database Setup Required Requires connection setup via DBI or odbc; most tutorials include examples.
Learning Curve Understanding both R and SQL together can take time; start with simple queries and dbplyr.
Performance Depends on Backend Query speed and efficiency depend on the underlying database (e.g., local SQLite vs. cloud BigQuery).
Limited Write Operations The R–SQL interface is optimized for reading and querying; heavy data writes or schema changes are better done directly in SQL clients.

7.5.5 When to Use SQL Within R

Scenario Recommended Approach
Need to analyze large marketing datasets stored remotely (e.g., BigQuery, Snowflake) Use DBI + dbplyr to query within R
Working with Parquet or Arrow files locally Use {arrow} to read and query data efficiently
Building automated marketing analytics workflows Integrate SQL queries into R scripts or Shiny dashboards
Combining SQL querying with modeling or visualization Use SQL within R for data extraction, then analyze in R

7.5.5.1 Summary

Using SQL within R empowers analysts to query big data and analyze results seamlessly in one environment. It reduces data transfer, improves reproducibility, and helps marketing professionals unlock insights from enterprise-level databases without switching tools.
