Time Decay Attribution: Basics Explained

Time decay attribution gives more credit to touchpoints closer to a conversion, helping marketers understand which interactions drive results. It’s ideal for businesses with longer sales cycles or multiple customer interactions.

Key Points:

• How It Works: Recent touchpoints get more credit using an exponential decay formula with a default 7-day half-life.
• Example: In a $1,000 purchase with 4 touchpoints, the conversion day might get 53.3% credit, while earlier touchpoints get less.
• Strengths: Highlights late-stage interactions, great for B2B or long sales cycles.
• Limitations: May undervalue early branding efforts and requires thorough data tracking.
• Tools: Platforms like Google Analytics and HubSpot support time decay attribution.

Quick Tip: Combine this model with others (e.g., first-touch) for a complete view of your marketing performance.

Time Decay Attribution Mechanics

Credit Distribution Formula

Time decay attribution works by assigning conversion credit based on how recently a touchpoint occurred, using an exponential decay formula and a half-life (default: seven days).

This model considers two key factors:

• The time elapsed between each touchpoint and the conversion
• The decay rate, determined by the half-life

For example, in a US$1,000 purchase with four touchpoints, the weights might look like this: 1 for the conversion day, 0.5 for 7 days prior, 0.25 for 14 days prior, and 0.125 for 28 days prior. These weights add up to 1.875. When normalized to 100% of the credit, the distribution would be:

Note: Percentages are calculated by dividing each initial weight by 1.875, then multiplying by 100. Attribution values are the corresponding percentage of US$1,000.

This method offers a structured way to allocate credit across touchpoints in marketing campaigns.

Time Decay Model in Practice

Let’s see how this model applies in a real-world scenario. Picture a B2B campaign where a customer interacts with multiple touchpoints:

• Engages with a LinkedIn ad 14 days before converting
• Downloads a whitepaper 7 days before converting
• Attends a webinar 5 days before converting
• Receives a follow-up email on the conversion day

Using a seven-day half-life, the initial weights would be: LinkedIn Ad (0.25), Whitepaper (0.5), Webinar (0.61), and Follow-up Email (1.0). After normalizing these weights, the credit distribution looks like this:

"Time-decay attribution is a multi-touch attribution model that gives some credit to all the channels that led to your customer converting, with that amount of credit being decayed the further back in time the channel was interacted with." – Dan Wakefield

This model is especially useful for businesses with longer sales cycles. It ensures early touchpoints are considered, while giving more weight to recent interactions that likely had a stronger influence on the final conversion.

Strengths and Limitations

Key Advantages

Time decay attribution gives more weight to recent interactions, reflecting how consumers often make decisions based on their latest experiences. This is especially helpful in industries like B2B software sales, where the buying process can take months. For example, it can pinpoint which late-stage touchpoints are most effective at driving conversions.

This model is particularly useful for fine-tuning multi-channel campaigns by helping marketers:

• Focus budgets on channels that deliver quick results
• Adjust strategies based on when touchpoints occur and their influence
• Measure how multiple interactions work together to drive results

Common Challenges

Despite its benefits, time decay attribution isn't without its challenges. Here's a quick overview:

The model's effectiveness depends on the industry and type of business. For example, a luxury car dealership might find it useful since customers often spend time researching before buying. On the other hand, businesses like fast-food chains, where decisions happen quickly, might not benefit as much.

One major drawback is that it can downplay early-stage branding efforts, which are crucial in some industries. To address this, many companies pair time decay attribution with other models or qualitative methods to get a broader view of their marketing performance. These challenges pave the way for diving into implementation details in the next section.

Setting Up Time Decay Attribution

Implementation Guide

To set up time decay attribution effectively, follow these steps to ensure accurate tracking and analysis:

• Channel Integration: Use UTM parameters, conversion tracking pixels, event tracking, and link CRM data to bring all your channels together.
• Quality Assurance: Regularly audit your tracking setup to maintain accuracy.

Once your tracking is in place, explore tools that can support and enhance your attribution model.

Making Data-Driven Decisions

Reading Attribution Reports

Time decay reports highlight the touchpoints closest to a conversion that drive the most results. To make the most of these reports, focus on analyzing key metrics like these:

Channel Performance Analysis

• Pinpoint which channels receive the most credit near conversions.
• Break down data by traffic source, campaign type, and device.
• Monitor engagement metrics such as email opens, product views, and add-to-cart actions.

Customer Journey Mapping

Understanding the entire conversion path allows you to improve each stage. Here's an example of a typical journey for a retailer:

These insights provide a foundation for improving campaign performance at every step.

Improving Campaign Performance

To get better results, concentrate your budgets on the most effective channels and fine-tune messaging for touchpoints that are closest to conversion.

Budget Allocation Strategy
Direct more resources to channels that consistently show strong results near conversion points.

Real-Time Optimization
Use live data to adjust campaigns on the fly. This includes monitoring conversion paths, tailoring messages for late-stage touchpoints, and integrating both online and offline data for a more complete picture.

Multi-Model Analysis

For a well-rounded understanding, combine time decay attribution with other models like position-based, first-touch, and data-driven approaches. This helps validate insights and captures both short-term and long-term factors influencing conversions.

To maintain strong campaign performance, regularly evaluate the entire conversion path. Balancing recent and historical interactions ensures you prioritize the touchpoints that drive the most impact while keeping all marketing stages effective. These insights allow you to refine your overall marketing strategy with confidence.
