  • Blog series part 1 : How to use Matomo to increase customer acquisitions for your business

    2 septembre 2020, par Joselyn Khor — Analytics Tips, Marketing

    Are you investing time and money into marketing your business and unsure if it’s paying off ? Web analytics provides the tools and insights to help you know which marketing channels to target and focus on. Without it you might be going in blind and missing opportunities that might’ve been easily found in your metrics.

    Increasing acquisition cheat sheet

    To increase customer acquisition on your website you need to first attract the right visitors to your website. Then capturing their attention and engaging them in your content. Finally you’ll want to convert by driving them through a streamlined funnel/buyer’s journey on your website all backed up by data.

    So, how do you attract audiences to your site with a web analytics tool like Matomo ?

    1. Figure out who your audience is through the Visitor Profiles feature. 
    2. Calculate the Cost of Customer Acquisition (CAC) to plan for growth. To grow and make your business/website sustainable, you’ll need to earn more money from a customer than you spend on acquiring them. How to calculate : Divide marketing spend by the number of customers acquired. 
    3. Figure out which marketing channels e.g., social media, PPC, SEO, content marketing, etc., you should invest more in and which of those you should focus less on.

    How to increase acquisitions with Matomo

    1. Use the Acquisitions feature
    2. Use funnels
    3. Study Visitor Profiles
    4. Focus on SEO efforts
    5. Look at the Multi Attribution feature
    6. Set goals
    7. Set Advanced eCommerce reporting

    1. Use the Acquisitions feature

    Matomo Analytics has a dedicated Acquisition feature to help with some of the heavy-lifting, making it easy for you to formulate targeted acquisition plans.

    Acquisitions feature

    This feature helps you learn who your potential customers are and figure out what marketing channels are converting the best for these visitors.

    • Learn what traffic you get from external websites : Knowing who’s helping you succeed from external websites is a crucial step to be able to focus your attention. Paid sponsorships, guest blog posts or even spending more on advertising on the particular website could result in greater traffic.
    • Social Networks : See which social media channels are connecting with the audiences you want. Take the guesswork out by using only the ones you need. By finding out which social channels your ideal audience prefers, you can generate shareable, convincing and engaging content to drive shares and traffic through to your site.
    • Campaigns : Your marketing team may have spent precious time and resource coming up with campaigns that are designed to succeed, but how can you be so sure ? With Campaigns you can understand what marketing campaigns are working, what aren’t, and shift your marketing efforts accordingly to gain more visitors, more effectively, with less costs. Keep track of every ad and content piece you display across internal and external channels to see which is having the biggest impact on your business objectives. Learn more

    2. Use funnels

    Creating conversion funnels gives you the big picture on whether your acquisition plans are paying off and where they may be falling short.

    Funnels feature

    If the ultimate goal of your site is to drive conversions, then each funnel can tell you how effectively you’re driving traffic through to your desired outcome.

    By integrating this with Visitor Profiles, you can view historic visitor profiles of any individual user at any stage of the conversion funnel. You see the full user journey at an individual level, including where they entered the funnel from and where they exited. Learn more

    How to amplify acquisition strategies with Funnels : Use conversion funnels to guide acquisition as you can tell which entry point is bringing the most success and which one needs more attention. Tailor your strategies to zone in on areas that have the most potential. You can identify where your visitors are encountering obstacles from the start, that are stopping them from progressing through their journey on your site.

    3. Study Visitor Profiles

    Visitor Profiles helps you understand visitors on a user-by-user basis, detailing each visitors’ history into a profile which summarises every visit, action and purchase made.

    Visitor Profiles feature

    Better understand :

    • Why your visitors viewed your website.

    • Why your returning visitors continue to view your website.

    • What specifically your visitors are looking for and whether they found it on your website.

    The benefit is being able to see how a combination of acquisition channels play a part in a single buyer’s journey.

    How Visitor Profiles helps with acquisition : By understanding the full behavioural patterns of any individual user coming through from external channels, you’ll see the path that led them to take action, where they may have gotten lost, and how engaged they are with your business over time. This gives you an indication of what kinds of visitors you’re attracting and helps you craft a buyer persona that more accurately reflects the audience most interested in you.

    4. Focus on SEO efforts

    Every acquisition plan needs a focus on maximising your Search Engine Optimization (SEO) efforts. When it comes to getting conclusive search engine referrer metrics, you need to be sure you’re getting ALL the insights to drive your SEO strategy.

    Integrate Google, Bing and Yahoo search consoles directly into your Matomo Analytics. This helps kickstart your acquisition goals as you rank highly for keywords that get the most traffic to your website.

    As another major SEO benefit, you can see how the most important search keywords to your business increased and decreased in ranking over time. 

    How to amplify acquisitions strategies with search engines and keywords : By staying on top of your competitors across ALL search engines, you may uncover traffic converting highly from one search engine, or find you could be losing traffic and business opportunities to your competitors across others.

    5. Look at the Multi Attribution feature

    Multi Attribution lets you measure the success of every touchpoint in the customer journey.

    Multi Attribution feature

    Accurately measure (and assign value to) channels where visitors first engaged with your business, where they came from after that, as well as the final channel they came from before purchasing your product or service.

    No longer falsely over-estimate any marketing channel and make smarter decisions when determining acquisition spend to accurately calculate the Customer Acquisition Cost (CAC). Learn more

    6. Set your Goals

    What are the acquisition goals you want to achieve the most ? The Goals feature lets you measure the most important metrics you need to grow your business.

    Goals feature

    Goals are crucial for building your marketing strategy and acquiring new customers. The more goals you track, the more you can learn about behavioural changes as you implement and modify paths that impact acquisition and conversions over time. You’ll understand which channels are converting the best for your business, which cities/countries are most popular, what devices will attract the most visitors and how engaged your visitors are before converting.

    This way you can see if your campaigns (SEO, PPC, signups, blogs etc.) or optimising efforts (A/B Testing, Funnels) have made an impact with the time and investment you have put in. Learn more

    7. Set Advanced Ecommence reporting

    If your website’s overall purpose is to generate revenue whether it be from an online store, asking for donations or from an online paid membership site ; the Ecommerce feature gives you comprehensive insights into your customers’ purchasing behaviours.

    Ecommerce feature

    When you use Ecommerce analytics, you heavily reduce risk when marketing your products to potential customers because you will understand who to target, what to target them with and where further opportunities exist to have the greatest impact for your business. Learn more

    Key takeaway

    Having the tools to ensure you’re creating a well planned acquisition strategy is key to attracting and capturing the attention of potential visitors/leads, and then driving them through a funnel/buyer’s journey on your website. Because of Matomo’s reputation as a trusted analytics platform, the features above can be used to assist you in making smarter data-driven decisions.

  • Your guide to cookies, web analytics, and GDPR compliance

    25 février 2020, par Joselyn Khor — Analytics Tips, Privacy, Security

    It’s been almost two years since the GDPR came into effect and turned the online world on its head. Confusion around cookies/cookie consent/cookie compliance remains till today. So we’d like to take this chance to talk more about the supposed “big bad” of the latest century. 

    Online cookies seem to have a bad reputation, but are they as bad as they seem ?

    To start, what are cookies on the internet ?

    An internet cookie a.k.a. an HTTP cookie, is a small piece of data sent from websites that is stored on your computer or mobile when you visit that site.

    Are all cookies bad ?

    No. Cookies themselves are usually harmless as they can’t infect computers with malware. 

    They can also be helpful for both websites who use them and individuals visiting those websites. For example, when online shopping, cookies on ecommerce sites keep track of what you’re shopping for. If you didn’t have that tracking, your cart would be empty every time you moved away from that site.

    For businesses/websites, cookies can be used for authentication (logins) and tracking website user experience. For example, tracking multiple visits to the same site in order to provide better experiences to customers visiting their website.

    internet cookies tracking

    The not-so-sweet types of cookies :

    Cookies that contain personal data

    Another example of a bad cookie is when cookies contain personal data directly in the cookie itself. For example, when websites store demographics or your name in a cookie ; or when a website stores survey results in a cookie. Use of cookies in these ways is considered bad practice nowadays.

    Third-party cookies

    They can be used by websites to learn about your visit and activity across multiple websites. Cookies can enter harmful territory when employed for “big brother” types of tracking i.e. when they’re used to build a virtual fingerprint of individuals after their activity is tracked from website to website. For example most advertising networks create third party cookies in your browser when you view an ad, which lets these advertisers track users across these websites and let companies buy more targeted ads.

    Why does Matomo use cookies ?

    web analytics cookies

    For accurate reporting of new and returning visitors. Matomo uses cookies to store some information about visitors between visits. We also use cookies to remember if someone gave consent to tracking, or opted out of tracking. 

    Types of cookies Matomo uses :

    • Matomo by default uses first-party cookies, set on the domain of your site.
    • Cookies created by Matomo start with : _pk_ref_pk_cvar_pk_id_pk_ses. See a list of all Matomo cookies : https://matomo.org/faq/general/faq_146/

    Cookie-less tracking - disable cookies and ensure cookie compliance :

    It’s possible to disable tracking cookies in Matomo by adding a line on the javascript code. When cookies are disabled, Matomo data will become slightly less accurateAlso, when cookies are disabled, there may still be a few cookies created in specific cases.

    If you disable cookies, Matomo tries to detect unique visitors by a fingerprint based on a few browser attributes : operating system, browser, browser plugins, IP address and browser language.

    By disabling tracking cookies, you may also use Matomo without needing to display a cookie consent screen. You can also keep tracking when they reject cookie consent by keeping cookies disabled.

    Cookies and the GDPR

    In some countries and according to the GDPR, websites need to provide a way for users to opt-out of all tracking, in particular tracking cookies.

    The GDPR regulates the use of cookies when they compromise an individual’s privacy. When cookies can identify an individual, it is considered personal data.

    cookies and GDPR

    Cookie compliance and the GDPR

    To be GDPR compliant you must :

    • Receive user consent before using any cookies (except strictly necessary cookies). Read more on cookies that are “clearly exempt from consent”.
    • Provide accurate and specific information about the data each cookie tracks and its purpose in plain language before consent is received.
    • Document and store consent received from users.
    • Allow users to access your service even if they refuse to allow the use of certain cookies
    • Make it as easy for users to withdraw their consent as it was for them to give their consent in the first place.

    When does GDPR require cookie consent ?

    The purpose of the GDPR is to give individuals control over their personal data. As such this regulation has provisions and requirements which regulate the processing of personal data to protect the privacy of individuals. 

    This means in order to use cookies, you will sometimes need explicit consent from those individuals.

    When does GDPR not require cookie consent ?

    Then there are many cookies that generally do NOT require consent (Source : https://wikis.ec.europa.eu/display/WEBGUIDE/04.+Cookies). 

    These are :

    • user input cookies, for the duration of a session
    • authentication cookies, for the duration of a session
    • user-centric security cookies, used to detect authentication abuses and linked to the functionality explicitly requested by the user, for a limited persistent duration
    • multimedia content player session cookies, such as flash player cookies, for the duration of a session
    • load balancing session cookies and other technical cookies, for the duration of session
    • user interface customisation cookies, for a browser session or a few hours, when additional information in a prominent location is provided (e.g. “uses cookies” written next to the customisation feature)

    Tracking cookies and consent vs legitimate interest

    cookie consent and GDPR legitimate interests

    User consent is not always required :

    We understand that whenever you collect and process personal data, you need – almost always – to ask for their consent. However, there are instances where you have to process data under “legitimate interests”. The GDPR states that processing of personal data is lawful “if processing is necessary for the purposes of the legitimate interests”. This means if you have “legitimate interests” you can avoid asking for consent for collecting and processing personal information. Learn more : https://cookieinformation.com/resources/blog/what-is-legitimate-interest-under-the-gdpr 

    A lawful basis for processing personal data (proceeding with caution) :

    We’ve also written about having a lawful basis for processing personal data under GDPR with Matomo. The caveat here is you need to have a strong argument for legitimate interests. If you are processing personal data which may represent a risk to the final user, then getting consent is, for us, still the right lawful basis. If you are not sure, at the time of writing ICO is providing a tool in order to help you make this decision.

    How is Matomo Analytics GDPR compliant ?

    Matomo can be configured to automatically anonymise data so you don’t process any personal data. This allows you to completely avoid GDPR. If you decide to process personal data, Matomo provides you with 12 steps to easily comply with the GDPR guidelines.

    New developments on cookies and the GDPR

    In the early days of the GDPR, a spate of cookie management platforms (CMPs) popped up to help websites and people comply with GDPR rules around cookies.

    These have become problematic in recent years. Europe’s highest court ruled pre-checked box for cookie boxes does not give enough consent

    As well as that, new research suggests most cookie consent pop-ups in the EU fall short of GDPR. A new study called, ‘Dark Patterns after the GDPR’ from MIT, UCL and Aarhus University found that a vast majority of websites aren’t following GDPR rules around cookies. The study found most cookie consent pop-ups in the EU to be undermining the GDPR by finding sneaky ways to convince website visitors to click ‘accept’.

  • Convert png images to HEVC with alpha video via ffmpeg [closed]

    6 mai 2024, par foxhable

    I am trying to create a video from a sequence of png images in the HEVC with alpha codec via ffmpeg.

    


    After the command

    


    ffmpeg -i a%d.png -r 30 -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 1 -vtag hvc1 ffmpeg-hevc.mov


    


    I get a video with a transparent background that opens in QuickTime, but not Safari.

    


    Info about this video via ffprobe :

    I compared this to a video that has a transparent background and works in Safari and QuickTime

    


    ffprobe movie-hevc.mov

        encoder         : HEVC


    


    The only thing I noticed is the encoder. In the working version this is HEVC but in my Lavc61.5.103 hevc_videotoolbox.

    


    The question is, is it possible to create a video with a native HEVC codec via ffmpeg ?
