  • Custom Segmentation Guide : How it Works & Segments to Test

    13 novembre 2023, par Erin — Analytics Tips, Uncategorized

    Struggling to get the insights you’re looking for with premade reports and audience segments in your analytics ?

    Custom segmentation can help you better understand your customers, app users or website visitors, but only if you know what you’re doing.

    You can derive false insights with the wrong segments, leading your marketing campaigns or product development in the wrong direction.

    In this article, we’ll break down what custom segmentation is, useful custom segments to consider, how new privacy laws affect segmentation options and how to create these segments in an analytics platform.

    What is custom segmentation ?

    Custom segmentation is when you divide your audience (customers, users, website visitors) into bespoke segments of your own design, not premade segments designed by the analytics or marketing platform provider.

    To do this, you single out “custom segment input” — data points you will use to pinpoint certain users. For example, it could be everyone who has visited a certain page on your site.

    Illustration of how custom segmentation works

    Segmentation isn’t just useful for targeting marketing campaigns and also for analysing your customer data. Creating segments is a great way to dive deeper into your data beyond surface-level insights.

    You can explore how various factors impact engagement, conversion rates, and customer lifetime value. These insights can help guide your higher-level strategy, not just campaigns.

    How custom segments can help your business

    As the global business world clamours to become more “data-driven,” even smaller companies collect all sorts of data on visitors, users, and customers.

    However, inexperienced organisations often become “data hoarders” without meaningful insights. They have in-house servers full of data or gigabytes stored by Google Analytics and other third-party providers.

    Illustration of a company that only collects data

    One way to leverage this data is with standard customer segmentation models. This can help you get insights into your most valuable customer groups and other standard segments.

    Custom segments, in turn, can help you dive deeper. They help you unlock insights into the “why” of certain behaviours. They can help you segment customers and your audience to figure out :

    • Why and how someone became a loyal customer
    • How high-order-value customers interact with your site before purchases
    • Which behaviours indicate audience members are likely to convert
    • Which traffic sources drive the most valuable customers

    This specific insight’s power led Gartner to predict that 70% of companies will shift focus from “big data” to “small and wide” by 2025. The lateral detail is what helps inform your marketing strategy. 

    You don’t need the same volume of data if you’re analysing and segmenting it effectively.

    Custom segment inputs : 6 data points you can use to create valuable custom segments 

    To help you get started, here are six useful data points you can use as a basis to create segments — AKA customer segment inputs :

    Diagram of the different possible custom segment inputs

    Visits to certain pages

    A basic data point that’s great for custom segments is visits to certain pages. Create segments for popular middle-of-funnel pages and compare their engagement and conversion rates. 

    For example, if a user visits a case study page, you can compare their likelihood to convert vs. other visitors.

    This is a type of behavioural segmentation, but it is the easiest custom segment to set up in terms of analysis and marketing efforts.

    Visitors who perform certain actions

    The other important type of behavioural segment is visitors or users who take certain actions. Think of things like downloading a file, clicking a link, playing a video or scrolling a certain amount.

    For instance, you can create a segment of all visitors who have downloaded a white paper. This can help you explore, for example, what drives someone to download a white paper. You can look at the typical user journey and make it easier for them to access the white paper — especially if your sales reps indicate many inbound leads mention it as a key driver of their interest.

    User devices

    Device-based segmentation lets you compare engagement and conversion rates on mobile, desktop and tablets. You can also get insights into their usage patterns and potential issues with certain mobile elements.

    This is one aspect of technographic segmentation, where you segment based on users’ hardware or software. You can also create segments based on browser software or even specific versions.

    Loyal or high-value customers

    The best way to get more loyal or high-value customers is to explore their journey in more detail. These types of segments can help you better understand your ideal customers and how they act on your site.

    You can then use this insight to alter your campaigns or how you communicate with your target audience.

    For example, you might notice that high-value customers tend to come from a certain source. You can then focus your marketing efforts on this source to reach more of your ideal customers.

    Visitor or customer source

    You need to track the results if you’re investing in marketing (like an influencer campaign or a sponsored post) outside platforms with their own analytics.

    Before you can create a reliable segment, you need to make sure that you use campaign tracking parameters to reliably track the source. You can use our free campaign tracking URL builder for that.

    Demographic segments — location (country, state) and more

    Web analytics tools, such as Matomo, use visitors’ IP addresses to pinpoint their location more accurately by cross-referencing with a database of known and estimated IP locations. In addition, these tools can detect a visitor’s location through the language settings in their browser. 

    This can help create segments based on location or language. By exploring these trends, you can identify patterns in behaviour, tailor your content to specific audiences, and adapt your overall strategy to better meet the preferences and needs of your diverse visitor base.

    How new privacy laws affect segmentation options

    Over the past few years, new legislation regarding privacy and customer data has been passed globally. The most notable privacy laws are the GDPR in the EU, the CCPA in California and the VCDPA in Virginia.

    Illustration of the impact of new privacy regulations on analytics

    For most companies, it can save a lot of work and future headaches to choose a GDPR-compliant web analytics solution not only streamlines operations, saving considerable effort and preventing future headaches, but also ensures peace of mind by guaranteeing the collection of compliant and accurate data. This approach allows companies to maintain compliance with privacy regulations while remaining firmly committed to a data-driven strategy.

    Create your very own custom segments in Matomo (while ensuring compliance and data accuracy)

    Crafting precise marketing messages and optimising ROI is crucial, but it becomes challenging without the right tools, especially when it comes to maintaining accurate data.

  • Converting `webm` to `mov` format using ffmpeg loses transparency - how can I keep it ?

    10 mars 2023, par M.A Shahbazi

    I am trying to convert a webm video to mov format without losing quality and transparency using the following command :

    


    ffmpeg -c:v libvpx-vp9 -i input.webm ouput.mov


    


    The video gets converted, but it loses transparency and the background of video is black.

    


    I also tried the following command :

    


    ffmpeg -c:v png -i input.webm output.mov


    


    But it gives me the following error output :

  • Cannot seem to work with mp3 files in pydub

    14 janvier 2023, par NegativePotato

    I have been trying to open mp3 files on pydub, I have ffmpeg in path and whatnot, but I get errors whenever I attempt to use pydub with mp3 files. Wav files work fine of course.
This is my code for testing purposes (copied directly from online) :

    


    from os import path
from pydub import AudioSegment

# files                                                                         
src = "Meet.mp3"
dst = "test.wav"

# convert wav to mp3                                                            
sound = AudioSegment.from_mp3(src)
sound.export(dst, format="wav")


    


    And this is my output for that code :
