• France rules Google Analytics non-compliant with GDPR

  11 février 2022, par Erin — Privacy

  Breaking news : The French Data Protection Agency, CNIL (Commission nationale de l’informatique et des libertés), has concluded that the use of Google Analytics is illegal under GDPR. The CNIL has begun issuing formal notices to website managers using Google Analytics.

  This follows the January 2022 Austrian Data Protection Authority’s decision to declare Google Analytics illegal to use under GDPR.

  Google Analytics GDPR breaches continue to spread through the EU

  Since the invalidation of the Privacy Shield framework, an agreement between the EU and US that allowed the transfer of data to certified US companies, the CNIL and other EU data protection authorities have received numerous complaints regarding data transfers collected during visits to websites using Google Analytics.

  "It’s interesting to see that the different European Data Protection Authorities all come to the same conclusion : the use of Google Analytics is illegal. There is a European task force and we assume that this action is coordinated and other authorities will decide similarly."

  About the CNIL’s decision

  In this model case, the CNIL has found that an unnamed website’s use of Google Analytics is non-compliant with GDPR because it had breached Article 44 which prohibits the transfer of personal data beyond the EU, unless the recipient country can prove adequate data protection. 

  Under the GDPR, personal data covers a range of identifiers including email address, race, gender, phone number to name a few, but the less obvious identifiers include IP addresses or cookie IDs, for instance. 

  The CNIL’s decision was based on the fact that the US does not meet GDPR sufficient levels of data protection as a result of US surveillance laws. Therefore, the unnamed website’s use of Google Analytics created risks for their website visitors when their personal data was exported to the US. 

  At the time of writing, it is unknown if the CNIL has issued a fine for the GDPR breach. However, the website manager of the unnamed website has been ordered by the CNIL to comply with the GDPR and, if necessary, stop using Google Analytics under the current conditions.

  "One thing we’re certain of is that these decisions will continue to roll out throughout the EU and potentially beyond.

  Other countries are imposing their own privacy regulations that closely mirror the GDPR like Brazil’s General Data Protection Law (LGPD), India’s Data Protection Bill, New Zealand’s Privacy Act and Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA) to name a few.”

  The CNIL offers an evaluation programme to help website managers determine whether web analytics solutions are exempt from collecting data prior to users’ agreement to opt-in through consent screens. Matomo, for instance, is a leading Google Analytics alternative that has been recommended by CNIL and is exempt from tracking consent. 

  

  English translation : “This is why I anticipated this announcement, gradually moving the analytics of my sites to @matomo_org since several weeks !

  “The @CNIL believes that the use of @googleanalytics is a violation of #GDPR”

  Immediate action required for Google Analytics users

  The CNIL and other EU-based data protection authorities have made their stance on Google Analytics clear and inaction will likely result in fines, which under the GDPR, can be up to €20 million or 4% of the organisation’s global turnover – whichever is higher.

  Based on the CNIL’s formal notice to the model case’s website manager, Google Analytics users should take immediate action to remove any chances of personal data being transferred to the US or find a Google Analytics alternative that is GDPR compliant. 

  

  English translation : “The CNIL considers that the use of Google Analytics is a violation of the GDPR. I use @matomo_org and I welcome it *winking face* It will squeal tires among growthackers who are slaughtering. Opportunity to look at alternative tools”

• 8 Best Tools to Analyse Website Traffic

  12 septembre 2023, par Erin — Analytics Tips, Marketing

  Do you want to analyse your website traffic ?

  Maybe you want to know how well you’re converting your traffic. Or maybe you’re looking to track the performance and ROI of your marketing campaigns. Regardless, you won’t get far without relying on a dependable web traffic analysis platform.

  In this article, we’ve compiled a list of the top web analytics tools available (including the pricing for each one).

  Let’s dive in.

  What is website traffic analysis ?

  Curious about what it means to analyse website traffic ?

  

  Simply put, it involves collecting and examining data about your website visitors and the actions they take. Marketers, analysts and website owners can then take this data and use it to optimise their strategy to improve site traffic, conversion rates and ROI.

  A website analytics tool is software that tracks and measures various visitor activities and behaviours on your website. Common metrics include pageviews, traffic source, bounce rate and average time on page. Using a web analytics solution can give you insights into what’s working (and what’s not working) so you can optimise your website, campaigns or marketing strategy.

  Advantages of using a website traffic analysis tool

  1. Performance measurement and optimisation

  Tracking the success of your marketing efforts is a challenging task. The primary benefit of using a web analytics tool is implementing effective performance measurement. If you don’t know how to measure your efforts, you won’t know what’s working and what’s not with your campaigns and content. 

  A web analysis tool can give you the insights you need to understand whether your marketing initiatives have been successful or if they need to be improved.

  For instance, your new web design facelift may seem beautiful, but if visitors aren’t staying on your site as long and it is resulting in lower conversions, then it’s time to go back to the drawing board.

  2. Audience insights to improve the user experience

  Web traffic analysis platforms don’t just show you what your visitors are doing. It shows you who your audience is. A powerful website analytics tool will give you in-depth audience data, including demographics like geographical location (e.g., city, state or country), to help you better understand your audience.

  Additionally, you can learn more about your audience by seeing how they interact with different content on your site. You’ll start to see that certain content performs better than others, giving you a greater understanding of your audience’s needs and wants. This means you’ll be able to tailor your website content and marketing efforts to your audience to improve the overall user experience.

  3. Improve SEO

  In the first two advantages, we touched on how insights can help you craft better content for the visitors already coming to your site to improve the user experience and improve conversions. But did you know that using a website analytics tool can also help improve how much traffic you’re getting to your site ?

  Since a web analytics tool can help you craft better content, one side effect is an increase in traffic from organic search through SEO. Additionally, your platform will likely show you other traffic sources that your visitors are coming from (i.e., another website is referring traffic to you) so you can tap into those high-performing sources and optimise your incoming traffic over time.

  Top 8 Tools to Analyse Website Traffic

  Here’s a breakdown of the top eight web analytics platforms to help you analyse each tool’s unique features, price, advantages and disadvantages so you can make the best decision.

• Google Optimize vs Matomo A/B Testing : Everything You Need to Know

  17 mars 2023, par Erin — Analytics Tips

  Google Optimize is a popular A/B testing tool marketers use to validate the performance of different marketing assets, website design elements and promotional offers. 

  But by September 2023, Google will sunset both free and paid versions of the Optimize product. 

  If you’re searching for an equally robust, but GDPR compliant, privacy-friendly alternative to Google Optimize, have a look at Matomo A/B Testing. 

  Integrated with our analytics platform and conversion rate optimisation (CRO) tools, Matomo allows you to run A/B and A/B/n tests without any usage caps or compromises in user privacy.

  Disclaimer : Please note that the information provided in this blog post is for general informational purposes only and is not intended to provide legal advice. Every situation is unique and requires a specific legal analysis. If you have any questions regarding the legal implications of any matter, please consult with your legal team or seek advice from a qualified legal professional.

  Google Optimize vs Matomo : Key Capabilities Compared 

  This guide shows how Matomo A/B testing stacks against Google Optimize in terms of features, reporting, integrations and pricing.

  Supported Platforms 

  Google Optimize supports experiments for dynamic websites and single-page mobile apps only. 

  If you want to run split tests in mobile apps, you’ll have to do so via Firebase — Google’s app development platform. It also has a free tier but paid usage-based subscription kicks in after your product(s) reaches a certain usage threshold. 

  Google Optimize also doesn’t support CRO experiments for web or desktop applications, email campaigns or paid ad campaigns.Matomo A/B Testing, in contrast, allows you to run experiments in virtually every channel. We have three installation options — using JavaScript, server-side technology, or our mobile tracking SDK. These allow you to run split tests in any type of web or mobile app (including games), a desktop product, or on your website. Also, you can do different email marketing tests (e.g., compare subject line variants).

  A/B Testing 

  A/B testing (split testing) is the core feature of both products. Marketers use A/B testing to determine which creative elements such as website microcopy, button placements and banner versions, resonate better with target audiences. 

  You can benchmark different versions against one another to determine which variation resonates more with users. Or you can test an A version against B, C, D and beyond. This is called A/B/n testing. 

  Both Matomo A/B testing and Google Optimize let you test either separate page elements or two completely different landing page designs, using redirect tests. You can show different variants to different user groups (aka apply targeting criteria). For example, activate tests only for certain device types, locations or types of on-site behaviour. 

  The advantage of Matomo is that we don’t limit the number of concurrent experiments you can run. With Google Optimize, you’re limited to 5 simultaneous experiments. Likewise, 

  Matomo lets you select an unlimited number of experiment objectives, whereas Google caps the maximum choice to 3 predefined options per experiment. 

  Objectives are criteria the underlying statistical model will use to determine the best-performing version. Typically, marketers use metrics such as page views, session duration, bounce rate or generated revenue as conversion goals. 

  

  Multivariate testing (MVT)

  Multivariate testing (MVT) allows you to “pack” several A/B tests into one active experiment. In other words : You create a stack of variants to determine which combination drives the best marketing outcomes. 

  For example, an MVT experiment can include five versions of a web page, where each has a different slogan, product image, call-to-action, etc. Visitors are then served with a different variation. The tracking code collects data on their behaviours and desired outcomes (objectives) and reports the results.

  MVT saves marketers time as it’s a great alternative to doing separate A/B tests for each variable. Both Matomo and Google Optimize support this feature. However, Google Optimize caps the number of possible combinations at 16, whereas Matomo has no limits. 

  Redirect Tests

  Redirect tests, also known as split URL tests, allow you to serve two entirely different web page versions to users and compare their performance. This option comes in handy when you’re redesigning your website or want to test a localised page version in a new market. 

  Also, redirect tests are a great way to validate the performance of bottom-of-the-funnel (BoFU) pages as a checkout page (for eCommerce websites), a pricing page (for SaaS apps) or a contact/booking form (for a B2B service businesses). 

  You can do split URL tests with Google Optimize and Matomo A/B Testing. 

  Experiment Design 

  Google Optimize provides a visual editor for making simple page changes to your website (e.g., changing button colour or adding several headline variations). You can then preview the changes before publishing an experiment. For more complex experiments (e.g., testing different page block sequences), you’ll have to codify experiments using custom JavaScript, HTML and CSS.

  In Matomo, all A/B tests are configured on the server-side (i.e., by editing your website’s raw HTML) or client-side via JavaScript. Afterwards, you use the Matomo interface to start or schedule an experiment, set objectives and view reports. 

  Experiment Configuration 

  Marketers know how complex customer journeys can be. Multiple factors — from location and device to time of the day and discount size — can impact your conversion rates. That’s why a great CRO app allows you to configure multiple tracking conditions. 

  Matomo A/B testing comes with granular controls. First of all, you can decide which percentage of total web visitors participate in any given experiment. By default, the number is set to 100%, but you can change it to any other option. 

  Likewise, you can change which percentage of traffic each variant gets in an experiment. For example, your original version can get 30% of traffic, while options A and B receive 40% each. We also allow users to specify custom parameters for experiment participation. You can only show your variants to people in specific geo-location or returning visitors only. 

  Finally, you can select any type of meaningful objective to evaluate each variant’s performance. With Matomo, you can either use standard website analytics metrics (e.g., total page views, bounce rate, CTR, visit direction, etc) or custom goals (e.g., form click, asset download, eCommerce order, etc). 

  In other words : You’re in charge of deciding on your campaign targeting criteria, duration and evaluation objectives.

  A free Google Optimize account comes with three main types of user targeting options : 

  • Geo-targeting at city, region, metro and country levels. 

  • Technology targeting  by browser, OS or device type, first-party cookie, etc. 
  • Behavioural targeting based on metrics like “time since first arrival” and “page referrer” (referral traffic source). 

  Users can also configure other types of tracking scenarios (for example to only serve tests to signed-in users), using condition-based rules. 

  Reporting 

  Both Matomo and Google Optimize use different statistical models to evaluate which variation performs best. 

  Matomo relies on statistical hypothesis testing, which we use to count unique visitors and report on conversion rates. We analyse all user data (with no data sampling applied), meaning you get accurate reporting, based on first-hand data, rather than deductions. For that reason, we ask users to avoid drawing conclusions before their experiment participation numbers reach a statistically significant result. Typically, we recommend running an experiment for at least several business cycles to get a comprehensive report. 

  Google Optimize, in turn, uses Bayesian inference — a statistical method, which relies on a random sample of users to compare the performance rates of each creative against one another. While a Bayesian model generates CRO reports faster and at a bigger scale, it’s based on inferences.

  Model developers need to have the necessary skills to translate subjective prior beliefs about the probability of a certain event into a mathematical formula. Since Google Optimize is a proprietary tool, you cannot audit the underlying model design and verify its accuracy. In other words, you trust that it was created with the right judgement. 

  In comparison, Matomo started as an open-source project, and our source code can be audited independently by anyone at any time. 

  Another reporting difference to mind is the reporting delays. Matomo Cloud generates A/B reports within 6 hours and in only 1 hour for Matomo On-Premise. Google Optimize, in turn, requires 12 hours from the first experiment setup to start reporting on results. 

  When you configure a test experiment and want to quickly verify that everything is set up correctly, this can be an inconvenience.

  User Privacy & GDPR Compliance 

  Google Optimize works in conjunction with Google Analytics, which isn’t GDPR compliant. 

  For all website traffic from the EU, you’re therefore obliged to show a cookie consent banner. The kicker, however, is that you can only show an Optimize experiment after the user gives consent to tracking. If the user doesn’t, they will only see an original page version. Considering that almost 40% of global consumers reject cookie consent banners, this can significantly affect your results.

  This renders Google Optimize mostly useless in the EU since it would only allow you to run tests with a fraction ( 60%) of EU traffic — and even less if you apply any extra targeting criteria. 

  In comparison, Matomo is fully GDPR compliant. Therefore, our users are legally exempt from displaying cookie-consent banners in most EU markets (with Germany and the UK being an exception). Since Matomo A/B testing is part of Matomo web analytics, you don’t have to worry about GDPR compliance or breaches in user privacy. 

  Digital Experience Intelligence 

  You can get comprehensive statistical data on variants’ performance with Google Optimize. But you don’t get further insights on why some tests are more successful than others. 

  Matomo enables you to collect more insights with two extra features :

  • User session recordings : Monitor how users behave on different page versions. Observe clicks, mouse movements, scrolls, page changes, and form interactions to better understand the users’ cumulative digital experience. 
  • Heatmaps : Determine which elements attract the most users’ attention to fine-tune your split tests. With a standard CRO tool, you only assume that a certain page element does matter for most users. A heatmap can help you determine for sure. 

  Both of these features are bundled into your Matomo Cloud subscription. 

  Integrations 

  Both Matomo and Google Optimize integrate with multiple other tools. 

  Google Optimize has native integrations with other products in the marketing family — GA, Google Ads, Google Tag Manager, Google BigQuery, Accelerated Mobile Pages (AMP), and Firebase. Separately, other popular marketing apps have created custom connectors for integrating Google Optimize data. 

  Matomo A/B Testing, in turn, can be combined with other web analytics and CRO features such as Funnels, Multi-Channel Attribution, Tag Manager, Form Analytics, Heatmaps, Session Recording, and more ! 

  You can also conveniently export your website analytics or CRO data using Matomo Analytics API to analyse it in another app. 

  Pricing 

  Google Optimize is a free tool but has usage caps. If you want to schedule more than 5 concurrent experiments or test more than 16 variants at once, you’ll have to upgrade to Optimize 360. Optimize 360 prices aren’t listed publicly but are said to be closer to six figures per year. 

  Matomo A/B Testing is available with every Cloud subscription (starting from €19) and Matomo On-Premise users can also get A/B Testing as a plugin (starting from €199/year). In each case, there are no caps or data limits.

  Final Thoughts : Who Benefits the Most From an A/B Testing Tool ?

  Split testing is an excellent method for validating various assumptions about your target customers. 

  With A/B testing tools you get a data-backed answer to research hypotheses such as “How different pricing affects purchases ?”, “What contact button placement generates more clicks ?”, “Which registration form performs best with new app subscribers ?” and more. 

  Such insights can be game-changing when you’re trying to improve your demand-generation efforts or conversion rates at the BoFu stage. But to get meaningful results from CRO tests, you need to select measurable, representative objectives.

  For example, split testing different pricing strategies for low-priced, frequently purchased products makes sense as you can run an experiment for a couple of weeks to get a statistically relevant sample. 

  But if you’re in a B2B SaaS product, where the average sales cycle takes weeks (or months) to finalise and things like “time-sensitive discounts” or “one-time promos” don’t really work, getting adequate CRO data will be harder. 

  To see tangible results from CRO, you’ll need to spend more time on test ideation than implementation. Your team needs to figure out : which elements to test, in what order, and why. 

  Effective CRO tests are designed for a specific part of the funnel and assume that you’re capable of effectively identifying and tracking conversions (goals) at the selected stage. This alone can be a complex task since not all customer journeys are alike. For SaaS websites, using a goal like “free trial account registration” can be a good starting point.

  A good test also produces a meaningful difference between the proposed variant and the original version. As Nima Yassini, Partner at Deloitte Digital, rightfully argues :

  “I see people experimenting with the goal of creating an uplift. There’s nothing wrong with that, but if you’re only looking to get wins you will be crushed when the first few tests fail. The industry average says that only one in five to seven tests win, so you need to be prepared to lose most of the time”.

  In many cases, CRO tests don’t provide the data you expected (e.g., people equally click the blue and green buttons). In this case, you need to start building your hypothesis from scratch. 

  At the same time, it’s easy to get caught up in optimising for “vanity metrics” — such that look good in the report, but don’t quite match your marketing objectives. For example, better email headline variations can improve your email open rates. But if users don’t proceed to engage with the email content (e.g. click-through to your website or use a provided discount code), your efforts are still falling short. 

  That’s why developing a baseline strategy is important before committing to an A/B testing tool. Google Optimize appealed to many users because it’s free and allows you to test your split test strategy cost-effectively. 

  With its upcoming depreciation, many marketers are very committed to a more expensive A/B tool (especially when they’re not fully sure about their CRO strategy and its results).
