How Does the Linear Attribution Model Calculate Credit: Unveiling the Distribution Process

In the realm of digital marketing, understanding how to allocate credit to various customer interactions along the sales journey is vital for evaluating the success of marketing campaigns.

The linear attribution model serves as a straightforward approach to this task by distributing credit equally across all touchpoints that a customer encounters before reaching a conversion event.

It operates on the premise that each step in the consumer journey, from the first exposure to the final decision, plays an integral role in the purchasing process.

Employing a linear attribution model allows marketers to gain a panoramic view of their efforts, appreciating every channel’s contribution without favoring one over another.

This approach simplifies the analysis of marketing touchpoints by treating them as equally important, which can be both an advantage and a limitation, depending on the complexity of the customer journey and the desired depth of insight.

Key Takeaways

  • The linear attribution model assigns equal credit to all marketing touchpoints.
  • This model facilitates a comprehensive understanding of a campaign’s performance.
  • It provides a balanced perspective but may not reflect the actual influence of each touchpoint.

Understanding Attribution Models

Attribution models are crucial in marketing analytics, allowing marketers to understand which touchpoints contribute to a conversion during a customer’s journey.

Basics of Attribution Models

Attribution models provide insights into the effectiveness of different marketing channels in influencing consumer behavior and driving conversions.

They are designed to assign credit to various marketing touchpoints a consumer interacts with before making a purchase or completing a desired action.

These models range from simplistic, single-touch attribution models, to more complex, multi-touch attribution models.

  • First-Touch Attribution: Credits the first interaction for the conversion.
  • Last-Touch Attribution: Assigns conversion credit to the last touchpoint.

These single-touch models, while easy to implement, often overlook the complexity of the customer journey.

Types of Attribution Models

As businesses grow more sophisticated in their marketing efforts, they often move toward multi-touch attribution models which distribute credit across several touchpoints.

  • Linear Attribution Model: Equally divides credit among all touchpoints.
  • Time Decay Model: Assigns more credit to touchpoints closer in time to the conversion.
  • Position-Based Attribution Model or U-Shaped Model: Credits a significant portion to both the first and last interaction, with the remainder distributed across other touchpoints.
  • Data-Driven Attribution: Analyzes actual data to attribute credit proportionally based on the impact of each touchpoint.

Each model serves to illuminate different aspects of the customer journey, aiding marketers in refining their strategies for maximum ROI.

Exploring Linear Attribution

Linear attribution is a critical element for marketers to weigh the impact of each touchpoint in a customer’s journey towards a conversion.

What Is Linear Attribution?

Linear attribution, sometimes known as the linear attribution model, operates under the premise that all touchpoints within the customer conversion path contribute equally to the end sale or conversion.

It acknowledges that consumers interact multiple times with a brand before making a purchase. For example, a buyer might click on an ad, read a blog post, and then receive an email campaign before ultimately deciding to buy.

In practice, linear attribution assigns an identical value to each touchpoint. If a consumer had five interactions with marketing material before purchasing, each touchpoint would receive 20% of the credit for that final sale.

This provides a more balanced view compared to single-touch attribution models, which might undervalue the role of certain consumer interactions.

One of the key advantages of a linear model is the holistic approach it offers, giving marketers visibility over the entire customer journey.

By doing so, they can make informed decisions on budget allocation and strategy adjustments to optimize marketing ROI.

This evenly spread credit model can be particularly useful for long sales cycles where multiple touchpoints are likely to influence the buyer’s decision-making process.

Implementing a linear attribution model can be instrumental for businesses that wish to move beyond the limitations of single-touch attribution, offering a more nuanced understanding of campaign performance.

Linear Attribution Mechanics

In the realm of digital marketing, linear attribution is a robust and equitable method of crediting various marketing touchpoints for a conversion. This section dissects how credit is distributed, ensuring that each element of the marketing mix is acknowledged for its role in driving performance.

Credit Distribution in Linear Attribution

The linear attribution model operates on the principle of evenly splitting the credit for a conversion across all the touchpoints a customer encounters on their journey.

To illustrate in a scenario where a customer interacted with five touchpoints before making a purchase, the linear attribution model would allocate 20% of the conversion credit to each of these touchpoints.

Steps to calculate credit in Linear Attribution:

  1. Identify all touchpoints: Locate every interaction the customer had with the brand, from the first ad click to the last engagement before conversion.
  2. Count the touchpoints: Tally up the total number of touchpoints.
  3. Divide equally: Assign an equal percentage of credit to each touchpoint. If there are five touchpoints, each receives 1/5th, or 20%, of the credit.

This model’s strength lies in its fairness; it acknowledges that no single touchpoint should monopolize the credit for the conversion, reflecting a comprehensive view of the consumer’s path to purchase.

Consequently, marketers can glean insights into the performance of each aspect of their strategy without overvaluing the first or last click.

By evenly distributing credit, the linear attribution model enhances the understanding of how different channels contribute collectively to the conversion process.

This information can be crucial for marketers when optimizing campaigns and allocating marketing budgets to maximize return on investment.

Applying Linear Attribution to Marketing Strategy

Implementing a linear attribution model provides valuable insights into how each marketing channel contributes to the end goal, supporting more informed decision making.

Incorporating Linear Attribution into Marketing Efforts

When marketers incorporate a linear attribution model, they adopt an equitable approach to credit distribution across all touchpoints in the consumer journey.

This involves tracking and analyzing the customer’s interactions with various marketing channels—such as social media, email campaigns, paid search, and direct traffic—to understand their role in driving conversions.

  • Data Collection: Marketers must ensure that they have the appropriate analytics tools in place to capture engagement data across all marketing channels.
  • Even Credit Allocation: As per the principles of the linear model, each marketing endeavor is assigned an equal portion of the conversion credit.

Analysis and Adjustment: By reviewing the performance data with the linear attribution model, marketers can identify patterns in customer behavior.

They might find that certain channels consistently appear in the conversion paths, even if they are not the final touchpoint before a purchase.

  • Budget Optimization: Armed with this knowledge, companies can make more strategic decisions about budget allocation.
  • Continuous Improvement: Marketing strategies must evolve as they learn from attribution data.

By recognizing the contribution of each channel, marketers are better positioned to refine their efforts for maximum impact.

Benefits and Limitations

In evaluating the linear attribution model, it’s essential to consider both the benefits it provides in terms of a comprehensive understanding of the customer journey, as well as its limitations regarding accuracy in specific marketing contexts.

Pros and Cons of Linear Attribution


  • Simplicity: This model is straightforward as it assigns equal credit to each touchpoint in a customer’s journey. Marketers find this approach uncomplicated for implementation.
  • Comprehensive Understanding: By considering all touchpoints, marketers gain a broad view of how each contributes to the final conversion, which prevents undervaluing any particular channel.


  • Lack of Accuracy for Individual Contributions: While simplicity is a strength, it can also be a drawback. The linear attribution model assumes each touchpoint contributes equally, which may not accurately reflect the impact of particular events in the buying process.
  • Potential Oversimplification: Some touchpoints might be more influential in driving conversions, but the linear model does not account for this, possibly leading to misinformed strategy adjustments.

Comparing with Other Models

Attribution models vary in complexity and the way they assign credit for customer conversions.

Understanding the fundamental differences between single-touch and multi-touch models, as well as comparing the linear model with other multi-touch frameworks, is essential in selecting the appropriate method for crediting marketing touchpoints.

Single-Touch vs Multi-Touch Models

Single-touch attribution models, such as the first-touch or last-touch models, assign 100% of the conversion credit to either the initial customer interaction or the final one before purchase, respectively.

This approach simplifies the analysis but often overlooks the complexity of the average buyer’s journey, potentially leading to skewed data.

On the other hand, multi-touch attribution models acknowledge that several marketing efforts contribute to the final conversion.

They assign credit across multiple touchpoints, thus providing a more holistic view of the customer’s journey.

The linear attribution model is one such multi-touch model that distributes credit equally to each interaction, regardless of their position in the sales funnel.

Linear vs Other Multi-Touch Models

Comparing the linear model to other multi-touch models like the time decay attribution model or the position-based attribution model highlights their varying approaches to credit distribution.

The time decay model gives more credit to touchpoints closer in time to the conversion event, while the position-based model, often referred to as the U-shaped model, assigns more weight to the first and last interactions.

The data-driven attribution goes a step further, applying algorithms to assign credit to each touchpoint based on actual data regarding their influence on the conversion.

This model is often considered the most accurate, but it requires substantial data and sophisticated analysis.

Assessing Performance and Insights

When implementing a linear attribution model, marketers meticulously track and analyze how credit is assigned for conversions and ROI.

This approach enables tailored strategies based on quantifiable metrics and enhances the refinement of marketing campaigns.

Tracking Conversions and ROI

Marketers measure conversions by attributing equal credit to each touchpoint in the customer journey.

For example, if a campaign has five touchpoints, in the linear model, each is credited with 20% contribution towards the final sale.

It is essential to monitor these touchpoints to determine their effectiveness.

The return on investment (ROI) is then calculated by comparing the cost of marketing efforts against the revenue generated from conversions attributed to those efforts.

By examining this data through thorough data analysis, organizations gain insights into which marketing tactics are working and which are not.

Making Data-Driven Decisions

With the linear attribution model, businesses are better equipped to make data-driven decisions.

The model’s evenly distributed credit assignment provides a broad perspective on the marketing metrics that influence customer behavior.

Firms utilize these insights to allocate budgets more effectively and tweak marketing strategies to optimize ROI.

This rigorous approach ensures that decisions are grounded in factual analysis rather than assumption, leading to a more strategic allocation of marketing resources.

Implementation in Analytics Tools

Implementing a linear attribution model within analytics tools requires a comprehensive understanding of the software’s features and settings.

The aim is to accredit equal value to all touchpoints that contributed to a conversion along the customer journey.

Using Google Analytics for Linear Attribution

Google Analytics provides a built-in feature for linear attribution, which is part of the Multi-Channel Funnels suite.

To utilize it, one must navigate to the Conversions section and then select the Multi-Channel Funnels report.

From there, accessing the Attribution Model Comparison Tool allows the user to choose the Linear model from a list of available models.

When using this model in Google Analytics, every touchpoint—whether it be a direct traffic visit, a social media interaction, or an email click—receives equivalent credit for a user’s conversion.

For example, if there are five touchpoints in a customer journey, the credit is evenly distributed, giving each touchpoint a 20% share of the conversion.

This approach ensures that no single channel’s impact is overstated or understated.

It is essential for users to familiarize themselves with the Date Range and Lookback Window controls within Google Analytics to accurately reflect the chosen business cycle and customer decision timeframe.

This will also ensure the proper allocation of conversion credit across the customer journey.

Custom Reports can also be created in Google Analytics to further analyze data as per the linear attribution model.

Users can consolidate and visualize the data by channel, campaign, or other dimensions to gain a nuanced understanding of the contribution each makes towards conversions.

By using Google Analytics for linear attribution, businesses can gain a more balanced view of their marketing efforts, allowing them to make more informed decisions on where to invest their marketing budget.

Impact on Marketing Activities

The linear attribution model plays a pivotal role in how marketing professionals allocate their budgets and structure their campaigns.

It offers a straightforward approach to credit distribution that influences marketing strategies across various platforms.

Effect on Budgeting and Campaigns

With the linear attribution model, each touchpoint in the customer journey receives equal credit for a conversion.

This can lead to more equitable budget distribution across marketing channels.

For instance, if a consumer interacts with a Facebook ad, an email campaign, and a search ad before making a purchase, each of these touchpoints is valued equally.

This uniform distribution model encourages marketers to invest in a more diversified mix of channels.

Rather than overfocusing on the last-click or first-click interaction, a marketer might spread their marketing budget to include Facebook ads, email campaigns, and other channels to ensure that each stage of the customer journey is funded and optimized.

In practice, the linear attribution model prompts marketers to sustain a consistent presence throughout the entire cycle of customer interactions.

This avoids undervaluing any single point of engagement, whether it be the initial awareness created by a Facebook ad or the reinforcement of decision-making provided by a follow-up email campaign.

The emphasis on every touchpoint can also lead to an overall increase in the marketing budget, as it becomes clear that maintaining a balance across multiple platforms and campaigns is necessary for an integrated and successful marketing strategy.

Customization and Advanced Techniques

In the evolving landscape of marketing analytics, the ability to customize attribution models and undertake systematic approaches to attribution is essential for capturing the nuances of consumer interactions.

Developing Custom Attribution Models

Custom attribution models allow businesses to go beyond standard formulas by considering unique aspects of their marketing strategies.

One can configure a custom model to weigh certain channels more heavily if deemed pivotal to the consumer’s path to purchase.

For instance, if a business finds that its webinars have a high conversion rate, it might assign increased credit to the webinar touchpoint using their custom attribution model.

It’s a method that recognizes the distinct impact of various marketing efforts, rather than treating them all uniformly.

Systematic Approach to Attribution

Employing a systematic approach to attribution involves applying a consistent framework that aligns with business objectives and data availability.

Organizations often deploy methodical testing phases, assessing different attribution models against observed outcomes to validate their effectiveness.

The focus is on creating a repeatable, scalable, and objective way to allocate credit among marketing touchpoints.

This systemic scrutiny helps marketers in reliably evaluating their channels’ performance and, as a result, optimize their marketing mix for better ROI.
