Which Google Ads Attribution Model Is Best For Your Business Objective?

At present, there are 6 different attribution models available in Google Ads conversion tracking. For those who do not have much knowledge about attribution modelling, choosing one among 6 could be a headache. In a broader perspective, attribution modelling can help  you understand when, how and why people converted on your website through Google Ads.

On the other hand, choosing a wrong attribution model can furnish inaccurate, incomplete data that can impact your success with Google Ads campaigns.

Here come the questions: What are the different attribution models to choose from? Which one is best for your business or business objective?

That’s what we are here to answer…..

Let’s dive deep into the ocean of Google Ads attribution modelling.

What are Google Ads attribution models?

attribution models
Attribution-Models

According to Google, “On the path to conversion, customers may do multiple searches and interact with multiple ads from the same advertiser. Attribution models let you choose how much credit each ad interaction gets for your conversions.”

 

Attribution is important, irrespective of your industry or your buying cycle. As more attribution models are created, it becomes more confusing to understand which one is the right one. Nowadays, without any data backing it, people start claiming a specific attribution model is right and best. The reality, however, is that no single attribution model can be the standalone source of accurate data — because no single attribution model can paint the full picture for decision making.

Why does it matter?

An attribution model is the rule, or set of rules, that determines how credit for sales and conversions is assigned to touchpoints in conversion paths.” – Google Analytics Help

Sounds simple right?

sounds right

Well, not really. It is not that simple in the era of digital marketing where a user gets exposed to multiple channels during its conversion path.

For a lead to convert, it takes around 7-13 touches or engagement with your business. This means that they could have visited your landing page or website with RLSA, display remarketing ads or other channels like Instagram, Twitter, Facebook etc.

Now you see the problem. With so many touches, you simply can’t give credit to a single channel for a conversion. All channels need not necessarily play an important role in lead nurturing. But you just can’t ignore a channel that pushes the lead down the funnel by an inch.

Here comes the importance of an attribution model. Attribution modeling seeks to offer visible data on what channels played the most important roles in converting a given prospect.

When should you choose the attribution model?

You must be wondering which attribution model is the right one. The truth is, it depends on what question you are trying to answer. That’s right — we are suggesting that you should use different attribution models to answer different questions.

Let’s take an example. You want to know which channels have first-click attribution. You need to answer the question, “Which channels generated new prospects?” Look at the first-click attribution model to answer this question. You also want to know which channels are closer to your conversion. Look at the last-touch attribution model to get the answer. 

At some point, it is likely that you’ll want to consider multi-channel performance. Looking at the multi-touch attribution model will definitely give you the answer. The multi-click attribution model you choose totally depends on your sales cycle and the questions you are looking to answer.

Hence, you must change the attribution model when you want to achieve a desired result. 

What happens if you change the attribution model in between?

An attribution model works on Google’s machine learning to analyze the touch points lying on a conversion path. It attributes credits to all/some touch points based on the attribution model included in a given conversion. Moreover, it ensures that you are able to extract the accurate data from your campaigns given that you have selected an attribution model with respect to your business objective.

With change in business/campaign objective, you may find a need to switch to a different attribution suitable to that objective. In this case if you switch the existing conversion attribution to the other model, chances are you may not get the desired results in early phases of the campaigns.

It is advisable that you should not switch an attribution model but create a new conversion with the required model. However, move to a data-driven attribution model (within the same conversion action) if it is available as this works effectively.

Which attribution model is best based on industry?

Well, you should not attach any specific attribution model to an industry.

So it depends.

Selecting an attribution model must be based on your business objective.

You might be having a new product in the pipeline and existing brands, too. Campaign objectives for both these would be completely different – hence the attribution model, too. Ensuring the right model will not only provide you accurate & clear data, but also help in taking strategic decisions for future success.

Which attribution model should you choose?

The objective of every marketing campaign is to generate the desired results, the success of which can be measured by analysing the contribution of different channels during a conversion path.

There is no hard and fast rule that describes a ‘best’ attribution model. It totally depends on your marketing objectives. The right attribution model defines the success of your marketing campaigns.

In Google Ads, the following 6 types of attribution model are available:

  1. First Click
  2. Last Click
  3. Position-Based
  4. Linear
  5. Time Decay
  6. Data-Driven

Let’s find out which attribution model you should choose based on your business objective.

Objective: Brand awareness

Attribution Model: First Click


What does it measure?

This attribution model attributes all credit for leads/sales generated to the original source.

First Click Attribution
First Click Attribution

When to use it?

Use the First-Click attribution model to understand which of  your sources are generating new prospects. You can run promotional campaigns to generate buzz about a new product.

 

Most effective

First Click works effectively if your advertising is limited to one or two channels. In this case a customer has limited options for finding your store. 

If you are in a position to expand your reach with new prospects or you are launching a new product, you could use this model to measure brand awareness & determine which channels are most likely to produce new leads/sales.

Objective: Email Marketing

Attribution Model: Last Click


What does it measure?

This attribution model attributes all credit for leads/sales generated to the last marketing touch point.

Last Click Attribution

When to use it?

To measure the success of an email marketing campaign, use Last-Click attribution model. 

For example, you run a campaign to your current customers with a promo code for 30% off and generate $20k revenue. All of that revenue would accurately be attributed to the email campaign with Last-Click attribution.


Most effective

Last-Click puts weight on the final actions before a conversion. With this model, analyze the “decision factor” that resulted in conversion. Last-Click works best for businesses with shorter sales cycles.

Objective: Sales & ROI

Attribution Model: Position-Based


What does it measure?

Position-Based attribution is also called U-shaped attribution. This attribution model attributes a higher value to the first and last touch (typically 40 percent each) and distributes the remaining value among all touch points in between.

Position Based Attribution
Position Based Attribution

When to use it?

If you want to simply look at all of the channels that are contributing (for increasing ROI), linear attribution could be a good model for you.

Let’s take an example.

A customer visits your store through Google organic search, then subscribes to your email list and clicks to your store from an email. Two months later they are re-marketed by a Google Ad and go to your store directly. A week later they see a Display Ad and make a purchase. The linear model would attribute maximum credit to organic search & Display Ad.

Most Effective

Position-Based attribution heavily gives credit to the channel that first brought in a customer as well as the channel that caused a conversion. But it also considers channels in between that helped nurture and keep your customers in the conversion path.

This helps you focus on channels that bring new customers in and channels at the bottom of the funnel.

Objective: Subscription

Attribution Model: Linear attribution


What does it measure?

Linear attribution model attributes equal credit for leads/sales generated to all the marketing touch points irrespective of their role in the sales cycle.

Linear Attribution
Linear Attribution

When to use it?

Use the Linear attribution model if you’re running a subscription service business that depends on periodic revenue and ongoing engagement with your product.


Most effective

The Linear attribution model is effective to measure overall brand reach & revenue, and to see which channels are consistently influential during a customer journey.

Objective: Maximize Repeat Customers

Attribution Model: Time Decay


What does it measure?

The Time Decay attribution model put more emphasis on channels closer to the conversion point and less to channels earlier in the funnel.

Time Decay Attribution
Time Decay Attribution

When to use it?

Time Decay is meant to assign credit to the channels that helped your prospect reach the conclusion to buy. If you have a long sales cycle and you’re trying to understand which channels push prospects from the nurture phase to the bottom of the funnel, this could be a good model for you.


Most effective

Since the Time Decay model gives credit to every marketing touch point, it works well for stores with a large amount of repeat customers. These customers come across different advertising and marketing methods, so using the Time Decay model can help you find what is driving repeat conversions.

Objective: Lead Generation

Attribution Model: Data Driven


What does it measure?

The Data-Driven attribution model, also known as Algorithm-Based attribution model uses Google machine learning technology to give credit to the most influential channels in the conversion process.

Data Driven Attribution
Data Driven Attribution

When to use it?

If you are running marketing campaigns across multiple platforms or running multiple campaigns in Google Ads itself, you should go for the Data-Driven attribution model.


Most effective

Since Data-Driven attribution works by crediting all the elements in a conversion funnel, businesses with huge spends should opt for it. 

Lead generation campaigns are where the customer does not immediately perform an action. Customers come across remarketing campaigns and other channels before conversion. Hence, you will be able to identify which channel/campaign is most effective by using the Data-Driven attribution model.

Conclusion

Attribution modeling offers you a clearer picture of what channels work for you for a lead to convert. It gives credit to different channels & campaigns/keywords based on the model you use. Attribution models are simply meant to help you better understand how and why a person converted.

Wrong attribution models will lead you to make poor decisions, while right models will unlock some powerful data.

Do not just rely on any specific attribution model but select one based on your business objectives. If a specific model does serve your purpose, then pick a new model or even compare a few models. Include them in your campaigns to make a marketing decision and see if they drive any incremental revenue for your business.

If you are looking for the best attribution model ad words, we’ll break it down for you. Attribution modelling is the method used to measure the financial effectiveness of a communication channel, along with the impact it has created on your business goals. The purpose of attribution modelling is to help you achieve your business goals, by highlighting what’s working and leveraging performance to increase profitability and reduce unnecessary expenditure. There are many models to choose from. 

  •     Last click: This is the default setting for Google Ads and Google Analytics. It gives credit for conversions/sales/ whatever your goal is to the last-clicked keyword or ad, etc. 
  •     Free click: First Click gives credit to the channel or keyword that first drove traffic to your site.
  •     Linear model: The linear model of attribution works by equally distributing the credit to every interaction a user takes before converting. 
  •     Time decay model: This gives maximum credit to actions that happened closer to a final conversion.
  •     Position-based model: Position-based modeling gives 40% of conversion credit to both the first and last touches and 20% to the remaining clicks on the journey.
  •     Data-driven model: It uses Google machine learning technology to give credit to the most influencer keywords in the conversion process

There is not one perfect or best attribution model. You can test what works best for you.

There are several different attribution models out there. Attribution modeling is a framework to analyse which touchpoints or marketing channels should receive credit for a conversion. Each attribution has a unique approach to distributing the value of a conversion across each touchpoint.. There are six common attribution models:

  • First Interaction
  • Last Interaction
  • Last Non-Direct Click
  • Linear
  • Time-Decay
  • Position-Based

By analyzing these attribution models, you can get a better idea of the ROI for each marketing channel. There isn't necessarily a "best" attribution model – you can simply choose one as your standard for reporting and analysis. Different factors, like business goals or buying cycles, can make one model better than another.

What is attribution model in google analytics? (KW: google analytics attribution models)

According to Google, Google attribution analytics models refer to the rules, or set of rules, that determine how credit for sales and conversions are assigned to touchpoints in conversion paths. For example, the Last Interaction model in Analytics assigns 100% credit to the final touchpoints (i.e., clicks) that immediately precede sales or conversions. First Interaction attribution assigns 100% credit to touchpoints that initiate conversion paths. There is no “best” or “perfect” attribution model.

You can choose one as your standard model for reporting and analytics purposes and determine what is giving you the best ROI. You can use the Multi-Channel Funnels and Model Comparison Tool to compare how different attribution models impact the valuation of your marketing channels.

If you have a Google Analytics account, you must have come across the by-now very common term, “attribution models.”

According to Google support, “You can use the Multi-Channel Funnels Model Comparison Tool to compare how different attribution models impact the valuation of your marketing channels.

In the tool, the calculated Conversion Value (and the number of conversions) for each of your marketing channels will vary according to the attribution model used. A channel that predominantly initiates conversion paths will have a higher Conversion Value according to the First Interaction attribution model than it would according to the Last Interaction attribution model.”

Whether you’re setting an attribution model for the first time or switching from one model to another, here is a basic breakdown of how to do it in your Google Analytics account.

  1.     In your Google Analytics dashboard, click Conversions > Multi-Channel Funnels > Attribution > Model Comparison. This allows you to view the various default models offered in the platform. 
  2.     Visit your first Campaign page, and then click in the Keywords tab to view the reporting table.
  3.     Click on Columnsà Custom Conversions à Google Analytics
  4.     Next click on Create to create a new column. This is where you select an attribution model, where campaign performance data will be filtered. 
  5.     From a list of options, choose your metric; this will be the attribution model used to understand your data. 
  6.     Click Save to use this model going forward.
