  • Use Google Analytics and risk fines, after CJEU ruling on Privacy Shield

    27 août 2020, par Joselyn Khor — Privacy

    EU websites using Google Analytics and Facebook are being targeted by European privacy group noyb after the invalidation of the Privacy Shield. They filed a complaint against 101 websites for continuing to send data to the US. 

    “A quick analysis of the HTML source code of major EU webpages shows that many companies still use Google Analytics or Facebook Connect one month after a major judgment by the Court of Justice of the European Union (CJEU) - despite both companies clearly falling under US surveillance laws, such as FISA 702. Neither Facebook nor Google seem to have a legal basis for the data transfers.”

    CJEU invalidates the Google Privacy Shield

    The Privacy Shield previously allowed for EU data to be transferred to the US. However, this was invalidated by the Court of Justice of the European Union (CJEU) on July 16, 2020. The CJEU deemed it illegal for any websites to transfer the personal data of European citizens to the US. 

    They also made it clear in a press release that “data subjects can claim compensation for inadmissible data exports (marginal no. 143 of the judgment). This should in particular include non-material damage (“compensation for pain and suffering”) and must be of a deterrent amount under European law.” Which puts extra financial pressure on websites to take the new ruling seriously.

    Immediate action is required after Google Privacy Shield invalidation

    The Berlin Commissioner for Data Protection and Freedom of Information therefore calls on all those responsible under its supervision to observe the decision of the ECJ [CJEU]. Those responsible who transfer personal data to the USA - especially when using cloud services - are now required to immediately switch to service providers in the European Union or in a country with an adequate level of data protection.

    The Berlin Commissioner for Data Protection and Freedom of Information

    As the ruling is effective immediately, there’s a pressing need for websites using Google Analytics to act, or face getting fined.

    What does this mean for you ?

    If you’re using Google Analytics the safest bet is to stop using it immediately

    "Neither Google Analytics nor Facebook Connect are necessary for the operation of these websites and could therefore have been replaced or at least deactivated in the meantime."

    Max Schrems, Honorary Chairman of noyb 

    If you still need to use it, then you’ll need to inform your visitors via a clear consent screen. This banner needs to make clear their personal data will be sent to the US, and to educate them about any potential risk related to this. They will then need to explicitly agree to this. 

    Another downside of cookie consent screens is that you may also suffer a damaging loss of visitors. After implementing cookie consent best practices, the UK’s data regulator the Information Commissioner’s Office (ICO) found a 90% drop in traffic, “implying a ninety percent drop in opt-in rates.”

    With an acceptance rate for such consent screens being lower than 10% your analytics becomes guesswork rather than science. 

    Looking for a privacy-respecting alternative to Google Analytics ?

    Privacy compliant Matomo Analytics is one of the best Google Analytics alternatives availalble. 

    With Matomo you’re able to continue using analytics without facing the wrath of both the GDPR and the CJEU. Matomo On-Premise lets you choose where your data is stored, so you can ensure no data is processed in the US. 

    Matomo is privacy-friendly and can be tweaked to comply with all privacy laws. Including the GDPR, HIPAA, CCPA and PECR.

  • Is Google Analytics Accurate ? 6 Important Caveats

    8 novembre 2022, par Erin

    It’s no secret that accurate website analytics is crucial for growing your online business — and Google Analytics is often the go-to source for insights. 

    But is Google Analytics data accurate ? Can you fully trust the provided numbers ? Here’s a detailed explainer.

    How Accurate is Google Analytics ? A Data-Backed Answer 

    When properly configured, Google Analytics (Universal Analytics and Google Analytics 4) is moderately accurate for global traffic collection. That said : Google Analytics doesn’t accurately report European traffic. 

    According to GDPR provisions, sites using GA products must display a cookie consent banner. This consent is required to collect third-party cookies — a tracking mechanism for identifying users across web properties.

    Google Analytics (GA) cannot process data about the user’s visit if they rejected cookies. In such cases, your analytics reports will be incomplete.

    Cookie rejection refers to visitors declining or blocking cookies from ever being collected by a specific website (or within their browser). It immediately affects the accuracy of all metrics in Google Analytics.

    Google Analytics is not accurate in locations where cookie consent to tracking is legally required. Most consumers don’t like disruptive cookie banners or harbour concerns about their privacy — and chose to reject tracking. 

    This leaves businesses with incomplete data, which, in turn, results in : 

    • Lower traffic counts as you’re not collecting 100% of the visitor data. 
    • Loss of website optimisation capabilities. You can’t make data-backed decisions due to inconsistent reporting

    For the above reasons, many companies now consider cookieless website tracking apps that don’t require consent screen displays. 

    Why is Google Analytics Not Accurate ? 6 Causes and Solutions 

    A high rejection rate of cookie banners is the main reason for inaccurate Google Analytics reporting. In addition, your account settings can also hinder Google Analytics’ accuracy.

    If your analytics data looks wonky, check for these six Google Analytics accuracy problems. 

    You Need to Secure Consent to Cookies Collection 

    To be GDPR-compliant, you must display a cookie consent screen to all European users. Likewise, other jurisdictions and industries require similar measures for user data collection. 

    This is a nuisance for many businesses since cookie rejection undermines their remarketing capabilities. Hence, some try to maximise cookie acceptance rates with dark patterns. For example : hide the option to decline tracking or make the texts too small. 

    Cookie consent banner examples
    Banner on the left doesn’t provide an evident option to reject all cookies and nudges the user to accept tracking. Banner on the right does a better job explaining the purpose of data collection and offers a straightforward yes/no selection

    Sadly, not everyone’s treating users with respect. A joint study by German and American researchers found that only 11% of US websites (from a sample of 5,000+) use GDPR-compliant cookie banners.

    As a result, many users aren’t aware of the background data collection to which they have (or have not) given consent. Another analysis of 200,000 cookies discovered that 70% of third-party marketing cookies transfer user data outside of the EU — a practice in breach of GDPR.

    Naturally, data regulators and activities are after this issue. In April 2022, Google was pressured to introduce a ‘reject all’ cookies button to all of its products (a €150 million compliance fine likely helped with that). Whereas, noyb has lodged over 220 complaints against individual websites with deceptive cookie consent banners.

    The takeaway ? Messing up with the cookie consent mechanism can get you in legal trouble. Don’t use sneaky banners as there are better ways to collect website traffic statistics. 

    Solution : Try Matomo GDPR-Friendly Analytics 

    Fill in the gaps in your traffic analytics with Matomo – a fully GDPR-compliant product that doesn’t rely on third-party cookies for tracking web visitors. Because of how it is designed, the French data protection authority (CNIL) confirmed that Matomo can be used to collect data without tracking consent.

    With Matomo, you can track website users without asking for cookie consent. And when you do, we supply you with a compact, compliant, non-disruptive cookie banner design. 

    Your Google Tag Isn’t Embedded Correctly 

    Google Tag (gtag.js) is a web tracking script that sends data to your Google Analytics, Google Ads and Google Marketing Platform.

    A corrupted gtag.js installation can create two accuracy issues : 

    • Duplicate page tracking 
    • Missing script installation 

    Is there a way to tell if you’re affected ?

    Yes. You may have duplicate scripts installed if you have a very low bounce rate on most website pages (below 15% – 20%). The above can happen if you’re using a WordPress GA plugin and additionally embed gtag.js straight in your website code. 

    A tell-tale sign of a missing script on some pages is low/no traffic stats. Google alerts you about this with a banner : 

    Google Analytics alerts

    Solution : Use Available Troubleshooting Tools 

    Use Google Analytics Debugger extension to analyse pages with low bounce rates. Use the search bar to locate duplicate code-tracking elements. 

    Alternatively, you can use Google Tag Assistant for diagnosing snippet install and troubleshooting issues on individual pages. 

    If the above didn’t work, re-install your analytics script

    Machine Learning and Blended Data Are Applied

    Google Analytics 4 (GA4) relies a lot on machine learning and algorithmic predictions.

    By applying Google’s advanced machine learning models, the new Analytics can automatically alert you to significant trends in your data. [...] For example, it calculates churn probability so you can more efficiently invest in retaining customers.

    On the surface, the above sounds exciting. In practice, Google’s application of predictive algorithms means you’re not seeing actual data. 

    To offer a variation of cookieless tracking, Google algorithms close the gaps in reporting by creating models (i.e., data-backed predictions) instead of reporting on actual user behaviours. Therefore, your GA4 numbers may not be accurate.

    For bigger web properties (think websites with 1+ million users), Google also relies on data sampling — a practice of extrapolating data analytics, based on a data subset, rather than the entire dataset. Once again, this can lead to inconsistencies in reporting with some numbers (e.g., average conversion rates) being inflated or downplayed. 

    Solution : Try an Alternative Website Analytics App 

    Unlike GA4, Matomo reports consist of 100% unsampled data. All the aggregated reporting you see is based on real user data (not guesstimation). 

    Moreover, you can migrate from Universal Analytics (UA) to Matomo without losing access to your historical records. GA4 doesn’t yet have any backward compatibility.

    Spam and Bot Traffic Isn’t Filtered Out 

    Surprise ! 42% of all Internet traffic is generated by bots, of which 27.7% are bad ones.

    Good bots (aka crawlers) do essential web “housekeeping” tasks like indexing web pages. Bad bots distribute malware, spam contact forms, hack user accounts and do other nasty stuff. 

    A lot of such spam bots are designed specifically for web analytics apps. The goal ? Flood your dashboard with bogus data in hopes of getting some return action from your side. 

    Types of Google Analytics Spam :

    • Referral spam. Spambots hijack the referrer, displayed in your GA referral traffic report to indicate a page visit from some random website (which didn’t actually occur). 
    • Event spam. Bots generate fake events with free language entries enticing you to visit their website. 
    • Ghost traffic spam. Malicious parties can also inject fake pageviews, containing URLs that they want you to click. 

    Obviously, such spammy entities distort the real website analytics numbers. 

    Solution : Set Up Bot/Spam Filters 

    Google Analytics 4 has automatic filtering of bot traffic enabled for all tracked Web and App properties. 

    But if you’re using Universal Analytics, you’ll have to manually configure spam filtering. First, create a new view and then set up a custom filter. Program it to exclude :

    • Filter Field : Request URI
    • Filter Pattern : Bot traffic URL

    Once you’ve configured everything, validate the results using Verify this filter feature. Then repeat the process for other fishy URLs, hostnames and IP addresses. 

    You Don’t Filter Internal Traffic 

    Your team(s) spend a lot of time on your website — and their sporadic behaviours can impair your traffic counts and other website metrics.

    To keep your data “employee-free”, exclude traffic from : 

    • Your corporate IPs addresses 
    • Known personal IPs of employees (for remote workers) 

    If you also have a separate stage version of your website, you should also filter out all traffic coming from it. Your developers, contractors and marketing people spend a lot of time fiddling with your website. This can cause a big discrepancy in average time on page and engagement rates. 

    Solution : Set Internal Traffic Filters 

    Google provides instructions for excluding internal traffic from your reports using IPv4/IPv6 address filters. 

    Google Analytics IP filters

    Session Timeouts After 30 Minutes 

    After 30 minutes of inactivity, Google Analytics tracking sessions start over. Inactivity means no recorded interaction hits during this time. 

    Session timeouts can be a problem for some websites as users often pin a tab to check it back later. Because of this, you can count the same user twice or more — and this leads to skewed reporting. 

    Solution : Programme Custom Timeout Sessions

    You can codify custom cookie timeout sessions with the following code snippets : 

    Final Thoughts 

    Thanks to its scale and longevity, Google Analytics has some strong sides, but its data accuracy isn’t 100% perfect.

    The inability to capture analytics data from users who don’t consent to cookie tracking and data sampling applied to bigger web properties may be a deal-breaker for your business.

  • Can't save a file in moviepy python

    23 juillet 2023, par user9102437

    I have seen a few questions about this here, but none of them solved the issue for me, so maybe my case is different in some way.

    


    I am trying to achieve a simple result : read a file and write it. Here is the code :

    


    import os
os.environ['FFMPEG_BINARY'] = '/usr/bin/ffmpeg'

from moviepy.editor import VideoFileClip
name = 'test.mp4'

clip = VideoFileClip('./vids/'+name)

clip.write_videofile('./vids/'+name, codec='libx264', fps=30)


    


    This code comes up with an error :

    


    ---> 88     '-r', '%.02f' % fps,
     89     '-an', '-i', '-'
     90 ]
     91 if audiofile is not None:
     92     cmd.extend([
     93         '-i', audiofile,
     94         '-acodec', 'copy'
     95     ])

TypeError: must be real number, not NoneType


    


    You may notice that I have set the environment variable for ffmpeg (I have also changed that in configure_defaults.py). This is because it was suggested in other questions. Also based on them I have run the following commands before running the code :

    


    sudo apt -y update
sudo apt -y install ffmpeg
pip install decorator
pip install moviepy --upgrade
pip install ffmpeg --upgrade


    


    I am using a Debian GNU/Linux 10 (buster) machine, and the versions of moviepy and ffmpeg are 1.0.3 and 4.1.10-0+deb10u1 respectively.

    


    Nothing seems to be helping to solve this. What am I missing here ?
