A Beginner’s Guide to Omnichannel Analytics
14 avril 2024, par ErinLinear customer journeys are as obsolete as dial-up internet and floppy disks. As a marketing manager, you know better than anyone that customers interact with your brand hundreds of times across dozens of channels before purchasing. That can make tracking them a nightmare unless you build an omnichannel analytics solution.
Alas, if only it were that simple.
Unfortunately, it’s not enough to collect data on your customers’ complex journeys just by buying an omnichannel platform. You need to generate actionable insights by using marketing attribution to tie channels to conversions.
This article will explain how to build a useful omnichannel analytics solution that lets you understand and improve the customer journey.
What is omnichannel analytics ?
Omnichannel analytics collects and analyses customer data from every touchpoint and device. The goal is to collect all this omnichannel data in one place, creating a single, real-time, unified view of your customer’s journey.
Unfortunately, most businesses haven’t achieved this yet. As Karen Lellouche Tordjman and Marco Bertini say :
“Despite all the buzz around the concept of omnichannel, most companies still view customer journeys as a linear sequence of standardised touchpoints within a given channel. But the future of customer engagement transforms touchpoints from nodes along a predefined distribution path to full-blown portals that can serve as points of sale or pathways to many other digital and virtual interactions. They link to chatbots, kiosks, robo-advisors, and other tools that customers — especially younger ones — want to engage with.”
However, doing so is more important than ever — especially when consumers have over 300 digital touchpoints, and the average number of touchpoints in the B2B buyer journey is 27.
Not only that, but customers expect personalised experiences across every platform — that’s the kind you can only create when you have access to omnichannel data.
What might omnichannel analytics look like in practice for an e-commerce store ?
An online store would integrate data from channels like its website, mobile app, social media accounts, Google Ads and customer service records. This would show how customers find its brand, how they use each channel to interact with it and which channels convert the most customers.
This would allow the e-commerce store to tailor marketing channels to customers’ needs. For instance, they could focus social media use on product discovery and customer support. Google Ads campaigns could target the best-converting products. While all this is happening, the store could also ensure every channel looks the same and delivers the same experience.
What are the benefits of omnichannel analytics ?
Why go to all the trouble of creating a comprehensive view of the customer’s experience ? Because you stand to gain some pretty significant benefits when implementing omnichannel analytics.
Understand the customer journey
You want to understand how your customers behave, right ? No other method will allow you to fully understand your customer journey the way omnichannel analytics does.
It doesn’t matter how customers engage with your brand — whether that’s your website, app, social media profiles or physical stores — omnichannel analytics capture every interaction.
With this 360-degree view of your customers, it’s easy to understand how they move between channels, where they encounter issues and what bottlenecks prevent them from converting.
Deliver better personalisation
We don’t have to tell you that personalisation matters. But do you know just how important it is ? Since 56% of customers will become repeat buyers after a personalised experience, delivering them as often as possible is critical.
Omnichannel analytics helps in your quest for personalisation by highlighting the individual preferences of customer segments. For example, e-commerce stores can use omnichannel analytics to understand how shoppers behave across different devices and tailor their offers accordingly.
Upgrade the customer experience
Omnichannel analytics gives you the insights to improve every aspect of the customer experience.
For starters, you can ensure a consistent brand experience across all your top channels by making sure they look and behave the same.
Then, you can use omnichannel insights to tailor each channel to your customers’ requirements. For example, most people interacting with your brand on social media may seek support. Knowing that you can create dedicated support accounts to assist users.
Improve marketing campaigns
Which marketing campaigns or traffic sources convert the most customers ? How can you improve these campaigns ? Omnichannel analytics has the answers.
When you implement omnichannel analytics you automatically track the performance of every marketing channel by attributing each conversion to one or more traffic sources. This lets you see whether Google Ads bring in more customers than your SEO efforts. Or whether social media ads are the most profitable acquisition channel.
Armed with this information, you can improve your marketing efforts — either by focusing on your profitable channels or rectifying problems that stop less profitable channels from converting.
What are the challenges of omnichannel analytics ?
There are three challenges when implementing an omnichannel analytics solution :
- Complex customer journeys : Customer journeys aren’t linear and can be incredibly difficult to track.
- Regulatory and privacy issues : When you start gathering customer data, you quickly come up against consumer privacy laws.
- No underlying goal : There has to be a reason to go to all this effort, but brands don’t always have goals in mind before they start.
You can’t do anything about the first challenge.
After all, your customer journey will almost never be linear. And isn’t the point of implementing an omnichannel solution to understand these complex journeys in the first place ? Once you set up omnichannel analytics, these journeys will be much easier to decipher.
As for the other two :
Using the right software that respects user privacy and complies with all major privacy laws will avoid regulatory issues. Take Matomo, for instance. Our software was designed with privacy in mind and is configured to follow the strictest privacy laws, such as GDPR.
Tying omnichannel analytics to marketing attribution will solve the final challenge by giving your omnichannel efforts a goal. When you tie omnichannel analytics to your marketing efforts, you aren’t just getting a 360-degree view of your customer journey for the sake of it. You are getting that view to improve your marketing efforts and increase sales.

How to set up an omnichannel analytics solution
Want to set up a seamless analytical environment that incorporates data from every possible source ? Follow these five steps :
Choose one or more analytics providers
You can use several tools to build an omnichannel analytics solution. These include web and app analytics tools, customer data platforms that centralise first-party data and business intelligence tools (typically used for visualisation).
Which tools you use will depend on your goals and your budget — the loftier your ambitions and the higher your budget, the more tools you can use.
Ideally, you should use as few tools as possible to capture your data. Most teams won’t need business intelligence platforms, for example. However, you may or may not need both an analytics platform and a customer data platform. Your decision will depend on how many channels your customers use and how well your analytics tool tracks everything.
If it can capture web and app usage while integrating with third-party platforms like your back-end e-commerce platform, then it’s probably enough.
Collect accurate data at every touchpoint
Your omnichannel analytics efforts hinge on the quantity and quality of data you can collect. You want to gather data from every touchpoint possible and store that data in as few places as possible. That’s why choosing as few tools as possible in the step above is so important.
So, where should you start ? Common data sources include :
- Your website
- Apps (iOS and Android)
- Social media profiles
- ERPs
- PoS systems
At the same time, make sure you’re tracking all relevant metrics. Revenue, customer engagement and conversion-focused metrics like conversion rate, dwell time, cart abandonment rate and churn rate are particularly important.
Set up marketing attribution
Setting up marketing attribution (also known as multi-touch attribution) is essential to tie omnichannel data to business goals. It’s the only way to know exactly how valuable each marketing channel is and where each customer comes from.
You’ll want to use multi-touch attribution, given you have data from across the customer journey.
Multi-touch attribution models can include (but are not limited to) :
- Linear : where each touchpoint is given equal weighting
- Time decay : where touchpoints are more valuable the nearer they are to conversion
- Position-based : where the first and last touch points are more valuable than all the others.
You don’t have to use just one of the models above, however. One of the benefits of using a web analytics tool like Matomo is that you can choose between different attribution models and compare them.

Create reports that help you visualise data
Dashboards are your friend here. They’ll let you see KPIs at a glance, allowing you to keep track of day-to-day changes in your customer journey. Ideally, you’ll want a platform that lets you customise dashboard widgets so only relevant KPIs are shown.
Setting up standard and custom reports is also important. Custom reports allow you to choose metrics and dimensions that align with your goals. They will also allow you to present your data most meaningfully to your team, increasing the likelihood they act upon insights.
Analyse data and take action
Now that you have customer journey data at your fingertips, it’s time to analyse it. After all, there’s no point in implementing an omnichannel analytics solution if you aren’t going to take action.
If you’re unsure where to start, re-read the benefits we listed at the start of this article. You could use your omnichannel insights to improve your marketing campaigns by doubling down on the channels that bring in the best customers.
Or you could identify (and fix) bottlenecks in the customer journey so customers are less likely to fall out of your funnel between certain channels.
Just make sure you take action based on your data alone.
Make the most of omnichannel analytics with Matomo
A comprehensive web and app analytics platform is vital to any omnichannel analytics strategy.
But not just any solution will do. When privacy regulations impede an omnichannel analytics solution, you need a platform to capture accurate data without breaking privacy laws or your users’ trust.
That’s where Matomo comes in. Our privacy-friendly web analytics platform ensures accurate tracking of web traffic while keeping you compliant with even the strictest regulations. Moreover, our range of APIs and SDKs makes it easy to track interactions from all your digital products (website, apps, e-commerce back-ends, etc.) in one place.

(C_UDP Socket Programming) How can I convert binary file to video format ?
30 avril 2024, par user24723398I am practicing UDP socket programming. My code's functions are below.


- 

- Connect Server-Client and send "hello" message each other (it is working).
- Then Server is sending video file to client (problem).






Transfer video file to client is working. But it is written in binary so I can't open the video.


So I try to use ffmpeg to convert the video, but it doesn't work.


Is there something wrong in my code ? How can I transfer a received file to a video file ?


My environment is MacOs.
