The Case for Personalization
Let’s say your conversion rate is at 3%, and you would like to get it up to 3.5%. This represents a 16.6% increase in sales (provided your AOV stays constant). If you have a turnover of $20M/yr, you would net an additional $3M/yr of revenue. With a 10% net profit margin, you would line your pockets with $333,000 in cash. Take $100,000 of that and invest in continued personalization and optimization efforts, and you will reap tremendous benefits.
Keep reading as I’ll give you ideas (with numbers) on how you can achieve this goal.
The core of this article is focused on two key areas:
- Precise details of what happened. A video recording, evidence of problems, etc. The more you provide the less time the developer will have to spend.
- Exactly when this happened. The closer to the accurate timestamp, the easier this is to triangulate in the logs.


Definition: The action of designing or producing something to meet someone's individual requirements.
We put names on bachelor gifts, write notes on Christmas cards, and license plates (ESCUZME or TIMELESS on a Delorean). While we have built personalization-heavy websites of this type, that’s not what I’m talking about.


I recently received this piece of mail. It honestly caught my eye as I saw my name on it—but Anna? I know several people whose name is Anna, but my wife’s name is Elissa. I applaud their attempt, but it fell quite short.
I can’t say I would have been tempted even if the name was right, but... this sealed the deal. Personalization done wrong will cost you sales. You will point customers to the wrong products, highlight the wrong things or make a mistake at this level.


When someone pops into your website for the first time, it’s like going to a grocery store on vacation: you are thinking “where are those marshmallows?” Then, you do your best to group by category (overhead signage on each aisle) to locate baking goods. According to this example, the grocery store would understand that some of its customers are here on vacation and marshmallows (for those finger-lickin-good s’mores) are going to be important. This is difficult to do given physical space constraints.
What could a brick/mortar store do? They could have someone standing at the door asking “what are you here for?” Some folks will choose to decline help, but there are others who would say “where’s the marshmallows?”


Hero images / Content changes / Store promotions through banners
These changes are not as customary as the previous two—but they are just as effective and, quite frankly, are easy to implement.
Google Optimize is my go-to solution here. You can use the free version to implement up to 10 personalizations. Of course, you should first A/B test the changes to ensure that there is a significant improvement. The only downside to Google Optimize is that you cannot target specific Google Analytics audiences (which would be super nice!). Google Optimize 360, which has this feature, among others, weighs in around $150,000 per year.
If you are engaged with a development team, you can also work through these changes with them. However, it’s much better to test your personalization theories with Google Optimize. But, if you need data fed to Google Optimize, in order for it to work, you would need a developer to aggregate the data to turn on the personalization engine.
Promotions can be a powerful way to motivate a quicker response.


How to build personalization
Personalization only works as well as the data it is fed. There are very few (if any) platforms that give insights from one website to another. Thus, when someone arrives on your website for the first time, the amount of data you have about them is next to nothing. As they interact with your website, you begin to build a picture of who they are.
Beyond this, rarely is personalization a good choice through just “machine learning.” While machine learning will augment your choices, it is not a substitute.


The easiest place to start is with customer feedback:
- What is returned most often?
- What do customers say they have the hardest time finding?
You will notice that some of the above can be solved by clearer information on product or category pages. But these are often bigger problems.
Personalization can solve problems. This is easier because you are working within an existing infrastructure.
But another place to look is what hasn’t yet been stated. Customers won’t tell you that they don’t think the order of the product listing is useful. They won’t tell you (maybe they might?) that they wish they had quick access to instructions. They won’t even consider how your website tells them whether or not this product will work for their use case.
Instead, they will happily (or maybe not happily) browse the website.


Person-based
Before we jump into this section, customizing based on customer input takes development effort. Most solutions are geared around actions as this is predictable from merchant to merchant.
I’d like to take the previous example of MarlowWhite.com. To be frank, they may be using personalization on their website as you won’t ever find an indicator saying “you are enjoying a site that is tuned to your needs + tastes.”
Marlow White is an excellent example of requesting data from the customer. They could build out the selections into their menu system, but instead, they give customers the ability to select what matches their criteria.


Google Optimize
Free
I love Google Optimize. It’s easy to get started (drag and drop). Reporting and metrics is tremendous. This ties nicely into Google Analytics reporting so you can apply segmentation on your tests—this is a powerful feature.
If you wish to pass in additional details, your developer can easily customize this. You can have 5 personalizations and 10 tests. The only disappointment is that you have to pay $150,000 a year (minimum) if you wish to target Google Analytics audiences. That’s a lot to swallow.
Optimizely
Starts at roughly $3,000/mo (or more)
We have used this in the past and was very impressed with its performance. Since they eliminated their capable free tier, we exclusively use Google Optimize.
For reference, Optimizely is more than $36,000 a year. There are a couple of other products, that I have never used, which have more palatable entry points:
- Convert: $700/mo (with yearly commitment)
- Proof (useproof.com): $80/mo
Here are some other options you can review:
- Qubit (no pricing listed)


How do we know this is working?
The worst thing ever would be to invest time or money into personalization only to have it backfire with a drop in conversion rate.
My suggestion is to focus on one piece of the puzzle at a time. You can watch the metrics coming back from this source.
Start small. Personalization is a process, and it’s not a destination.
For example, your email marketing automations will tell you the revenue for each automation or campaign. Algolia won’t tell you revenue numbers, but your developers can add a flag to enable/disable personalization based on a flag from Google Optimize—then you can create segments in Google Analytics for the A and B versions and compare any desired statistics.
I will note that Adobe Commerce’s Recommendations / Live Search have limited reporting. These tools are either enabled or disabled, so it’s a matter of trusting that Adobe has done their due-diligence.


Survey / form results
This is my favorite way. The key is to tell your visitor why you are asking, putting them back in control.
Go to MarlowWhite.com and roll your mouse over the Army menu. This is so apparent that an explanation isn’t even necessary!
But, what about putting a drop-down menu just below the header that says “To better customize this website for your needs, what type of business do you represent?” You won’t get 100% of people providing details, but it will be quite a few. Popups are also a possibility, but I wouldn’t recommend using them unless the visitor shows signals that they are engaged (they are viewing the page for 30 seconds or clicking into another page).
The Benchmade Knife Finder is also a brilliant use for this. It’s not as obvious, but Benchmade is quickly getting the idea of what this visitor is looking for.
