Attribution modeling can be confusing, but choosing the right model can make or break digital analytics of websites or content. Attribution modeling is the analysis of content or website performance that gives credit for the sales and conversions to specific points along the conversion path. This will be translated to English as we go along.

The most commonly used attribution models are: First Interaction (Click), Last Interaction (Click), Linear, Position-Based, and Time Decay.
Digital marketers will choose between one of these or several other attribution models in order to provide credit to different points in the conversion path based on the priorities of a company. The conversion path is/are “the steps taken by a user of a website towards a desired end from the standpoint of the website operator or marketer.” [3]
Essentially, we are assigning what we perceive to be the value of each step a potential customer takes towards a purchase. For example:
Google Ad (first click) Social Media (second click)
Email Campaign (third click)
Direct Click to Purchase (last click)
First Interaction(Click) Attribution Model
“First-Click Attribution is a type of web analytics model in which the first click that brings a visitor to a website is given credit for any sale or conversion that ultimately takes place.” Essentially, any link to the website itself, not just the product, is credited with the sale of a product or service. Generally speaking, this would be the advertisement. [1]

Last Interaction(Click) Attribution Model
“Last-Click Attribution refers to a web analytics model in which the “last click” is given credit for a sale or conversion.” This is an analytics model which favors the last site, link, or advertisement that brought a user to the ultimate goal of the website, whether that be a purchase or a conversion of some kind. Notably, Google Analytics uses Last Click Attribution. [2]

Linear Attribution Model
In Linear Attribution Models, each touchpoint on the conversion path would share equal credit for the purchase or conversion. For example, say a customer saw a shared ad for a helmet, then went on the social media account of the helmet producer, then clicked on the link where they can purchase the helmet. Linear Attribution would give equal credit to the ad, the social media profile, and the purchasing link for the sale.

Position-Based Attribution Model
Position-Based Attribution Models generally credit 40% to first interaction, 40% to last interaction, and the remaining 20% is divided evenly amongst the intermediary touchpoints. Essentially, this model provides the most credit to your two most important touchpoints: the one that got them interested, and the one that made the sale.

Time Decay Attribution Model
In Time Decay Attribution Modeling, credit appreciates as a potential customer travels along the conversion path. The system gives the least credit to first interaction, the most to last interaction, and increases with each touchpoint in between. It’s AT&T’s favorite model. Get it? Raising the bars.

Hi Thomas,
I really enjoyed your blog! Your cover photo intrigued me to look at your blog first because it had motion. In class, I was very lost in the differences between the attribution models, but your blog covered it very well. Your design is very clean cut and easy to follow; there are a lot of diagrams but they were spread out enough to not look too overcrowded. Good job!
Thomas,
This is probably one of the coolest blogs I’ve seen this entire semester! It looks like you really took your time. The featured image is fun and interactive, the blog is easy to navigate, and the content is extremely informative. Great Job!
This blog was so well done! The little video gif in the beginning really caught my eye and made me intrigued to read the rest of the blog
Thomas,
Super cool blog! I loved the use of moving images and how perfectly everything was spaced out. I could tell that you took time when creating this. Very informative and fun to read.
