Most individuals agree that the data you use determines the quality of your ideas and analysis. Essentially, junk data in = rubbish analysis out. Data cleaning, also known as data cleansing and data scrubbing, is a critical step for your organization if you want to foster a culture of quality data decision-making.

What is Data Cleaning in Marketing?

Data cleaning is the process of correcting or deleting inaccurate, corrupted, poorly formatted, duplicate, or incomplete data from a dataset. When various data sources are combined, there is a high risk of data duplication or mislabeling. If the data is inaccurate, the outcomes and algorithms are untrustworthy, even if they appear proper.

There is no one definitive way to prescribe the exact procedures in the data cleaning process because the processes differ from dataset to dataset. However, it is critical to create a template for your data cleaning procedure so that you can ensure you are doing it correctly each time.

Data cleaning is the process of removing data that does not belong in a dataset. Data transformation is the conversion of data from one format or structure to another. Transformation operations, often known as data wrangling or data munging, involve changing and mapping data from one “raw” data type to another for storage and analysis. This article focuses on the techniques for cleansing that data.

How Data Cleansing Can Boost Your Marketing Campaign?

Do you know what drives effective marketing campaigns? The data is critical for your B2B marketing effort.

However, the quality of your data is equally important as the quantity. Inaccurate, obsolete, or redundant data can stymie your marketing efforts and result in wasted opportunities. Here, data purification is critical for data collection in order to refine and optimize your dataset. Let’s look at how data cleansing can be the secret weapon that takes your marketing strategy to new heights!

1. Enhancing Targeted Marketing:

Precise targeting can set up a successful marketing campaign. Data cleansing ensures that your customer database is accurate and up-to-date, allowing you to identify and segment your audience. Removing obsolete or incorrect information can create more targeted and personalized marketing messages that resonate with your audience.

Imagine sending a promotional email to a prospect only to realize that the contact information is outdated. Not only does this result in a missed opportunity, but it can also harm your brand’s reputation. Data cleansing mitigates these risks, allowing you to deliver your message to the right audience at the right time.

2. Improving Customer Experience:

A seamless and personalized customer experience is a cornerstone of effective marketing. Clean data helps you understand your customers better, track their preferences, and anticipate their needs. Eliminating duplicate records and ensuring accurate information helps deliver a consistent and positive customer experience across all touchpoints.

Customers today expect brands to know them and provide relevant content. Data cleansing empowers you to meet these expectations by maintaining a database that reflects the current state of your customer relationships.

3. Boosting Email Marketing Effectiveness:

Email marketing remains a powerful tool in the marketer’s arsenal, but its success hinges on the accuracy of your email lists. Data cleansing helps eliminate invalid email addresses, reduce bounce rates and increase deliverability. It enhances the overall effectiveness of your email campaigns.

A clean email list ensures that your marketing analytics are reliable. Accurate data allows you to measure your campaigns, identify areas for improvement, and make data-driven decisions for future initiatives.

4. Strengthening Decision-Making with Accurate Analytics:

Accurate data is the foundation of insightful analytics. Cleansing your data ensures the metrics and insights derived from your marketing efforts are reliable and actionable. Clean data allows you to track the performance of different campaigns, channels, and strategies.

Whether it is about conversion rates, customer acquisition costs, or the effectiveness of specific marketing channels, clean data provides a clear and accurate picture. It empowers your team to make informed decisions, allocate resources wisely, and optimize your marketing strategy for maximum impact.

5. Saving Time and Resources:

Maintaining a clean dataset improves the quality of your marketing efforts and saves valuable time and resources. Manually sorting through inaccurate or outdated information is time-consuming. You can automate through data-cleansing tools and processes.

Clean data demonstrates your commitment to accuracy and reliability, instilling confidence in your customers and prospects. 

When your audience knows their information is handled well, they may like to engage with your brand and share accurate details to strengthen your marketing efforts.

How to Clean Data

While the approaches for data cleansing may differ depending on the types of data your company stores, you may utilize these fundamental stages to create a framework for your organization.

Remove duplicate or irrelevant observations

Remove any undesirable observations from your dataset, including duplicates and irrelevant observations. Duplicate observations will occur most frequently during data collection. When you integrate data sets from numerous sources, scrape data, or acquire data from clients or departments, you may end up with duplicate data. De-duplication is one of the most significant aspects to consider in this process. Irrelevant observations occur when you discover observations that do not apply to the specific topic you are attempting to analyze.

For example, if you wish to study data on millennial clients but your dataset includes older generations, you may want to delete those observations. This can improve analysis efficiency and reduce distraction from your core goal, as well as produce a more manageable and performant dataset.

Fix structural errors

Structural errors occur when you measure or transfer data and encounter unusual naming practices, typos, or erroneous capitalization. These contradictions can result in mislabeled groups or classes. For example, you may see “N/A” and “Not Applicable” appear together, but they should be treated as the same category.

Filter unwanted outliers

Often, there will be one-off observations that do not appear to fit inside the data you are examining. If you have a valid justification for removing an outlier, such as incorrect data entry, doing so will improve the performance of the data you are working with.

However, occasionally the presence of an anomaly proves a theory you are working on. Remember that just because an outlier occurs does not imply it is erroneous. This step is required to determine the legitimacy of the number. If an outlier is unrelated to the analysis or is an error, consider eliminating it.

Handle missing data

You can’t ignore missing data because many algorithms will not accept missing values. There are a couple of ways to deal with missing data. Neither is optimal, but both can be considered.

1. As a first option, you can drop observations that have missing values, but doing this will drop or lose information, so be mindful of this before you remove it.
2. As a second option, you can input missing values based on other observations; again, there is an opportunity to lose integrity of the data because you may be operating from assumptions and not actual observations.
3. As a third option, you might alter the way the data is used to effectively navigate null values.

Validate and QA

At the end of the data cleaning process, you should be able to answer these questions as a part of basic validation:

• Does the data make sense?
• Does the data follow the appropriate rules for its field?
• Does it prove or disprove your working theory, or bring any insight to light?
• Can you find trends in the data to help you form your next theory?
• If not, is that because of a data quality issue?

False inferences based on erroneous or “dirty” data can lead to poor business strategy and decisions. False conclusions can result in an uncomfortable moment in a reporting meeting when you learn your data does not hold up under scrutiny. Before you get there, you need to establish a culture of quality data in your firm. To accomplish this, you should document the tools you intend to employ to foster this culture, as well as your definition of data quality.

What Kind of Data Errors Does Data Scrubbing Fix?

Data cleansing corrects a variety of problems and issues in data collection, including erroneous, invalid, incompatible, and corrupt data. Some of these issues are caused by human error during the data entry process, while others are caused by the usage of diverse data structures, formats, and language across many systems within an organization.

The following are examples of concerns that are typically addressed as part of data cleansing projects:

• Typos and invalid or missing data. Data cleansing corrects various structural errors in data sets. For example, that includes misspellings and other typographical errors, wrong numerical entries, syntax errors, and missing values, such as blank or null fields that should contain data.
• Inconsistent data. Names, addresses, and other attributes are often formatted differently from system to system. For example, one data set might include a customer’s middle initial, while another doesn’t. Data elements such as terms and identifiers may also vary. Data cleansing helps ensure that data is consistent so it can be analyzed accurately.
• Duplicate data. Data cleansing identifies duplicate records in data sets and either removes or merges them through the use of deduplication measures. For example, when data from two systems is combined, duplicate data entries can be reconciled to create single records.
• Irrelevant data. Some data — outliers or out-of-date entries, for example — may not be relevant to analytics applications and could skew their results. Data cleansing removes redundant data from data sets, which streamlines data preparation and reduces the required amount of data processing and storage resources.

Conclusion

Data cleansing, also known as data cleaning or data scrubbing, is the process of correcting inaccurate, incomplete, duplicate, or otherwise erroneous data in a dataset. It entails finding data mistakes and then modifying, updating, or eliminating data to remedy them. Data cleansing enhances data quality and contributes to more accurate, consistent, and reliable information for organizational decision-making.
