  • vc2enc : halve allocated table size, refactor and optimize quantization

    26 février 2016, par Rostislav Pehlivanov
    vc2enc : halve allocated table size, refactor and optimize quantization
    

    Since coefficients differ only in the last bit when writing to the
    bitstream it was possible to remove the sign from the tables, thus
    halving them. Also now all quantization is done in the unsigned domain
    as the sign is completely separate, which gets rid of the need to do
    quantization on 32 bit signed integers.

    Overall, this slightly speeds up the encoder depending on the machine.
    The commit still generates bit-identical files as before the commit.

  • What is Audience Segmentation ? The 5 Main Types & Examples

    16 novembre 2023, par Erin — Analytics Tips

    The days of mass marketing with the same message for millions are long gone. Today, savvy marketers instead focus on delivering the most relevant message to the right person at the right time.

    They do this at scale by segmenting their audiences based on various data points. This isn’t an easy process because there are many types of audience segmentation. If you take the wrong approach, you risk delivering irrelevant messages to your audience — or breaking their trust with poor data management.

    In this article, we’ll break down the most common types of audience segmentation, share examples highlighting their usefulness and cover how you can segment campaigns without breaking data regulations.

    What is audience segmentation ?

    Audience segmentation is when you divide your audience into multiple smaller specific audiences based on various factors. The goal is to deliver a more targeted marketing message or to glean unique insights from analytics.

    It can be as broad as dividing a marketing campaign by location or as specific as separating audiences by their interests, hobbies and behaviour.

    Illustration of basic audience segmentation

    Audience segmentation inherently makes a lot of sense. Consider this : an urban office worker and a rural farmer have vastly different needs. By targeting your marketing efforts towards agriculture workers in rural areas, you’re honing in on a group more likely to be interested in farm equipment. 

    Audience segmentation has existed since the beginning of marketing. Advertisers used to select magazines and placements based on who typically read them. They would run a golf club ad in a golf magazine, not in the national newspaper.

    How narrow you can make your audience segments by leveraging multiple data points has changed.

    Why audience segmentation matters

    In a survey by McKinsey, 71% of consumers said they expected personalisation, and 76% get frustrated when a vendor doesn’t deliver.

    Illustrated statistics that show the importance of personalisation

    These numbers reflect expectations from consumers who have actively engaged with a brand — created an account, signed up for an email list or purchased a product.

    They expect you to take that data and give them relevant product recommendations — like a shoe polishing kit if you bought nice leather loafers.

    If you don’t do any sort of audience segmentation, you’re likely to frustrate your customers with post-sale campaigns. If, for example, you just send the same follow-up email to all customers, you’d damage many relationships. Some might ask : “What ? Why would you think I need that ?” Then they’d promptly opt out of your email marketing campaigns.

    To avoid that, you need to segment your audience so you can deliver relevant content at all stages of the customer journey.

    5 key types of audience segmentation

    To help you deliver the right content to the right person or identify crucial insights in analytics, you can use five types of audience segmentation : demographic, behavioural, psychographic, technographic and transactional.

    Diagram of the main types of audience segmentation

    Demographic segmentation 

    Demographic segmentation is when you segment a larger audience based on demographic data points like location, age or other factors.

    The most basic demographic segmentation factor is location, which is easy to leverage in marketing efforts. For example, geographic segmentation can use IP addresses and separate marketing efforts by country. 

    But more advanced demographic data points are becoming increasingly sensitive to handle. Especially in Europe, GDPR makes advanced demographics a more tentative subject. Using age, education level and employment to target marketing campaigns is possible. But you need to navigate this terrain thoughtfully and responsibly, ensuring meticulous adherence to privacy regulations.

    Potential data points :

    • Location
    • Age
    • Marital status
    • Income
    • Employment 
    • Education

    Example of effective demographic segmentation :

    A clothing brand targeting diverse locations needs to account for the varying weather conditions. In colder regions, showcasing winter collections or insulated clothing might resonate more with the audience. Conversely, in warmer climates, promoting lightweight or summer attire could be more effective. 

    Here are two ads run by North Face on Facebook and Instagram to different audiences to highlight different collections :

    Each collection is featured differently and uses a different approach with its copy and even the media. With social media ads, targeting people based on advanced demographics is simple enough — you can just single out the factors when making your campaign. But if you don’t want to rely on these data-mining companies, that doesn’t mean you have no options for segmentation.

    Consider allowing people to self-select their interests or preferences by incorporating a short survey within your email sign-up form. This simple addition can enhance engagement, decrease bounce rates, and ultimately improve conversion rates, offering valuable insights into audience preferences.

    This is a great way to segment ethically and without the need of data-mining companies.

    Behavioural segmentation

    Behavioural segmentation segments audiences based on their interaction with your website or app.

    You use various data points to segment your target audience based on their actions.

    Potential data points :

    • Page visits
    • Referral source
    • Clicks
    • Downloads
    • Video plays
    • Goal completion (e.g., signing up for a newsletter or purchasing a product)

    Example of using behavioural segmentation to improve campaign efficiency :

    One effective method involves using a web analytics tool such as Matomo to uncover patterns. By segmenting actions like specific clicks and downloads, pinpoint valuable trends—identifying actions that significantly enhance visitor conversions. 

    Example of a segmented behavioral analysis in Matomo

    For instance, if a case study video substantially boosts conversion rates, elevate its prominence to capitalise on this success.

    Then, you can set up a conditional CTA within the video player. Make it pop up after the user has watched the entire video. Use a specific form and sign them up to a specific segment for each case study. This way, you know the prospect’s ideal use case without surveying them.

    This is an example of behavioural segmentation that doesn’t rely on third-party cookies.

    Psychographic segmentation

    Psychographic segmentation is when you segment audiences based on your interpretation of their personality or preferences.

    Potential data points :

    • Social media patterns
    • Follows
    • Hobbies
    • Interests

    Example of effective psychographic segmentation :

    Here, Adidas segments its audience based on whether they like cycling or rugby. It makes no sense to show a rugby ad to someone who’s into cycling and vice versa. But to rugby athletes, the ad is very relevant.

    If you want to avoid social platforms, you can use surveys about hobbies and interests to segment your target audience in an ethical way.

    Technographic segmentation

    Technographic segmentation is when you single out specific parts of your audience based on which hardware or software they use.

    Potential data points :

    • Type of device used
    • Device model or brand
    • Browser used

    Example of segmenting by device type to improve user experience :

    Upon noticing a considerable influx of tablet users accessing their platform, a leading news outlet decided to optimise their tablet browsing experience. They overhauled the website interface, focusing on smoother navigation and better readability for tablet users. These changes offered tablet users a seamless and enjoyable reading experience tailored precisely to their device.

    Transactional segmentation

    Transactional segmentation is when you use your customers’ purchase history to better target your marketing message to their needs.

    When consumers prefer personalisation, they typically mean based on their actual transactions, not their social media profiles.

    Potential data points :

    • Average order value
    • Product categories purchased within X months
    • X days since the last purchase of a consumable product

    Example of effective transactional segmentation :

    A pet supply store identifies a segment of customers consistently purchasing cat food but not other pet products. They create targeted email campaigns offering discounts or loyalty rewards specifically for cat-related items to encourage repeat purchases within this segment.

    If you want to improve customer loyalty and increase revenue, the last thing you should do is send generic marketing emails. Relevant product recommendations or coupons are the best way to use transactional segmentation.

    B2B-specific : Firmographic segmentation

    Beyond the five main segmentation types, B2B marketers often use “firmographic” factors when segmenting their campaigns. It’s a way to segment campaigns that go beyond the considerations of the individual.

    Potential data points :

    • Company size
    • Number of employees
    • Company industry
    • Geographic location (office)

    Example of effective firmographic segmentation :

    Companies of different sizes won’t need the same solution — so segmenting leads by company size is one of the most common and effective examples of B2B audience segmentation.

    The difference here is that B2B campaigns are often segmented through manual research. With an account-based marketing approach, you start by researching your potential customers. You then separate the target audience into smaller segments (or even a one-to-one campaign).

    Start segmenting and analysing your audience more deeply with Matomo

    Segmentation is a great place to start if you want to level up your marketing efforts. Modern consumers expect to get relevant content, and you must give it to them.

    But doing so in a privacy-sensitive way is not always easy. You need the right approach to segment your customer base without alienating them or breaking regulations.

    That’s where Matomo comes in. Matomo champions privacy compliance while offering comprehensive insights and segmentation capabilities. With robust privacy controls and cookieless configuration, it ensures GDPR and other regulations are met, empowering data-driven decisions without compromising user privacy.

  • Top Conversion Metrics to Track in 2024

    22 janvier 2024, par Erin

    2023 boasts  2.64 billion online shoppers worldwide ; that’s more than a third of the global population. With these numbers on an upward trajectory in 2024, conversion metrics are more important than ever to help marketers optimise the online shopping experience. 

    In this article, we’ll provide predictions for the most important conversion metrics you should keep track of in 2024. We’ll also examine how social media can make or break your brand engagement strategy. Keep reading to stay ahead of the competition for 2024 and gain tips and tricks for improving conversion performance.

    What are conversion metrics ?

    In technical terms, conversion metrics are the quantifiable measurements used to track the success of specific outcomes on a website or marketing campaign. Conversion metrics demonstrate how well your website prompts visitors to take desirable actions, like signing up for a newsletter, making a purchase, or filling out a form, for instance.

    Let’s say you’re running a lemonade stand, and you want to compare the number of cups sold to the number of people who approached your stand (your conversion rate). This ratio of cups sold to the total number of people can help you reassess your sales approach. If the ratio is low, you might reconsider your approach ; if it’s high, you can analyse what makes your technique successful and double down.

    In 2023, we saw the average conversion rate for online shopping grow by 5.53% compared to the previous year. An increase in conversion rate typically indicates a higher percentage of website visitors converting to buyers. It can also be a good sign for marketing teams that marketing campaigns are more effective, and website experiences are more user-friendly than the previous year. 

    Conversion metrics are a marketers’ bread and butter. Whether it’s through measuring the efficacy of campaigns, honing in on the most effective marketing channels or understanding customer behaviour — don’t underestimate the power of conversion metrics. 

    Conversion rate vs. conversion value 

    Before we dive into the top conversion metrics to track in 2024, let’s clear up any confusion about the difference between conversion rate and conversion value. Conversion rate is a metric that measures the ratio of website visitors/users who complete a conversion action to the total number of website visitors/users. Conversion rates are communicated as percentages.

    A conversion action can mean many different things depending on your product or service. Some examples of conversion actions that website visitors can take include : 

    • Making a purchase
    • Filling out a form
    • Subscribing to a newsletter
    • Any other predefined goal

    Conversion rate is arguably one of the most valuable conversion metrics if you want to pinpoint areas for improvement in your marketing strategy and user experience (UX).

    A good conversion rate completely depends on the type of conversion being measured. Shopify has reported that the average e-commerce conversion rate will be 2.5%-3% in 2023, so if you fall anywhere in this range, you’re in good shape. Below is a visual aid for how you can calculate conversion rate depending on which conversion actions you decide to track :

    Conversion rate formula calculation

    Conversion value is also a quantifiable metric, but there’s a key difference : conversion value assigns a numerical value to each conversion based on the monetary value of the completed conversion action. Conversion value is not calculated with a formula but is assigned based on revenue generated from the conversion. Conversion value is important for calculating marketing efforts’ return on investment (ROI) and is often used to allocate marketing budgets better. 

    Both conversion rate and conversion value are vital metrics in digital marketing. When used in tandem, they can provide a holistic perspective on your marketing efforts’ financial impact and success. 

    9 important conversion metrics to track in 2024

    Based on research and results from 2023, we have compiled this list of predictions for the most important metrics to track in 2024.

    1. Conversion rate 

    To start things out strong, we’ve got the timeless and indispensable conversion rate. As we discussed in the previous section, conversion rate measures how successfully your website convinces visitors to take important actions, like making purchases or signing up for newsletters. 

    An easy-to-use web analytics solution like Matomo can help in tracking conversion rates. Matomo automatically calculates conversion rates of individual pages, overall website and on a goal-by-goal basis. So you can compare the conversion rate of your newsletter sign up goal vs a form submission goal on your site and see what is underperforming and requires improvement.

    Conversion rates by different Goals in Matomo dashboard

    In the example above in Matomo, it’s clear that our goal of getting users to comment is not doing well, with only a 0.03% conversion rate. To improve our website’s overall conversion rate, we should focus our efforts on improving the user commenting experience.

    For 2024, we predict that the conversion rate will be just as important to track as in 2023. 

    2. Average visit duration

    This key metric tracks how long users spend on your website. A session typically starts when a user lands on your website and ends when they close the browser or have been inactive for some time ( 30 minutes). Tracking the average visit duration can help you determine how well your content captures users’ attention or how engaged users are when navigating your website. 

    Average Visit Duration = Total Time Spent / Number of Visits

    Overview of visits and average visit duration in Matomo

    Web analytics tools like Matomo help in monitoring conversion rate metrics like average visit duration. Timestamps are assigned to each interaction within a visit, so that average visit duration can be calculated. Analysing website visit information like average visit duration allows you to evaluate the relevance of your content with your target audience. 

    3. Starter rate

    If your business relies on getting leads through forms, paying attention to Form Analytics is crucial for improving conversion rates. The “starter rate” metric is particularly important—it indicates the number of who people start filling out the form, after seeing it. 

    When you’re working to increase conversion rates and capture more leads, keeping an eye on the starter rate helps you understand where users might encounter issues or lose interest early in the form-filling process. Addressing these issues can simplify the form-filling experience and increase the likelihood of successful lead captures.

    4. Bounce rate

    Bounce rate reflects the percentage of visitors who exit your site after interacting with a single page. Bounce rate is an important metric for understanding how relevant your content is to visitors or how optimised your user experience is. A high bounce rate can indicate that visitors are having trouble navigating your website or not finding what they’re looking for. 

    Matomo automatically calculates bounce rate on each page and for your overall website.

    Bounce rate trends in Matomo dashboard

    Bounce Rate = (# of Single-Page Sessions / Total # of Sessions) * 100

    5. Cost-per-conversion

    This metric quantifies the average cost incurred for each conversion action (i.e., sale, acquired lead, sign-up, etc.). Marketers use cost-per-conversion to assess the cost efficiency of a marketing campaign. You want to aim for a lower cost-per-conversion, meaning your advertising efforts aren’t breaking the bank. A high cost-per-conversion could be acceptable in luxury industries, but it often indicates a low marketing ROI. 

    Cost-per-Conversion = Ad Spend / # of Conversions

    By connecting your Matomo with Google Ads through Advertising Conversion Export feature in Matomo, you can keep tabs on your conversions right within the advertising platform. This feature also works with Microsoft Advertising and Yandex Ads.

    6. Average order value (AOV)

    AOV is a conversion metric that calculates the average monetary value of each order. AOV is crucial for helping e-commerce businesses understand the value of their transactions. A high AOV means buyers spend more per transaction and could be more easily influenced by upselling or cross-selling. Low AOV isn’t necessarily bad — you can compensate for a low AOV by boosting transaction volume. 

    Evolution of average order value (AOV) in Matomo

    AOV = Total Revenue / Total # of Orders 

    Matomo automatically tracks important e-commerce metrics such as AOV, the percentage of visits with abandoned carts and the conversion rate for e-commerce orders.

    7. Exit rate

    Exit rate measures the percentage of visitors who leave a specific webpage after viewing it. Exit rate differs from bounce rate in that it focuses on the last page visitors view before leaving the site. A high exit rate should be examined to identify issues with visitors abandoning the specific page. 

    Exit Rate = (# of Exits from a Page / Total # of Pageviews for that Page) * 100

    Matomo dashboard showing exit rate by page

    In the Matomo report above, it’s clear that 77% of visits to the diving page ended after viewing it (exit rate), while 23% continued exploring. 

    On the other hand, our products page shows a lower exit rate at 36%, suggesting that more visitors continue navigating through the site after checking out the products.

    How to improve your conversion performance 

    If you’re curious about improving your conversion performance, this section is designed to guide you through that exact process.

    A bar graph with an orange arrow showing an increasing trend

    Understand your target audience and their behaviour

    You may need to return to the drawing board if you’re noticing high bounce rates or a lack of brand engagement. In-depth audience analysis can unveil user demographics, preferences and behaviours. This type of user data is crucial for building user personas, segmenting your visitors and targeting marketing campaigns accordingly.

    You can segment your website visitors in a number of web analytics solutions, but for the example below, we’ll look at segmenting in Matomo. 

    Segmented view of mobile users in Matomo

    In this instance, we’ve segmented visitors by mobile users. This helps us see how mobile users are doing with our newsletter signup goal and identify the countries where they convert the most. It also shows how well mobile users are doing with our conversion goal over time.

    It’s clear that our mobile users are converting at a very low rate—just 0.01%. This suggests there’s room for improvement in the mobile experience on our site.

    Optimise website design, landing pages, page loading speed and UX

    A slow page loading speed can result in high exit rates, user dissatisfaction and lost revenue. Advanced web analytics solutions like Matomo, which provides heatmaps and session recordings, can help you find problems in your website design and understand how users interact with it.

    Making a website that focuses on users and has an easy-to-follow layout will make the user experience smooth and enjoyable.

    Create compelling calls-to-action (CTA)

    Research shows that a strategically placed and relevant CTA can significantly increase your revenue. CTAs guide prospects toward conversion and must have a compelling and clear message. 

    You can optimise CTAs by analysing how users interact with them — this helps you tailor them to better resonate with your target audience. 

    A/B testing

    A/B testing can improve your conversion performance by allowing you to experiment with different versions of a web page. By comparing the impact of different web page elements on conversions, you can optimise your website with confidence. 

    Key conversion metrics takeaways

    Whether understanding user behaviour to develop a more intuitive user experience or guessing which marketing channel is the most effective, conversion metrics can be a marketer’s best friend. Conversion metrics help you save time, money and headaches when making your campaigns and website as effective as possible. 

    Make improving conversion rates easier with Matomo, a user-friendly all-in-one solution. Matomo ensures reliable insights by delivering accurate data while prioritising compliance and privacy.
