"Να είσαι θερμοστάτης, όχι θερμόμετρο" είναι μια φράση που άκουσα πριν μερικά χρόνια από έναν guru του χώρου και μου έχει μείνει καρφωμένη στο μυαλό από τότε! Το θερμόμετρο είναι μια συσκευή η οποία μόνο καταγράφει δεδομένα, ενώ ένας θερμοστάτης μετατρέπει τα δεδομένα και σε ενέργειες. Αν καταφέρουμε να έχουμε περισσότερους "έξυπνους θερμοστάτες" στην διάθεση μας όταν αναλύουμε δεδομένα, θα μπορέσουμε να διαχειριστούμε και πολύ μεγαλύτερο όγκο αλλά και να επιταχύνουμε τις αντιδράσεις μας σε αυτά.

Tracking Pageviews in Analytics using page visibility (by Philip Walton)

I came across an interesting alternative approach from Philip Walton. He explains clearly why all websites cannot work with the default definition of a page view in Analytics and how we someone could start using the page’s visibility state (using the Page visibility API). Unfortunately this post was originally published in 2017 and still until today, even though Single Page Application (SPA) websites are widely used, we reply mostly on complicated implementations to virtually create page views for analytics tracking. Another alternative to this problem is to use an Event Driven Data Layer (EDDL), but I like the simplicity of...

Scalable website audit for analysts using the cloud

Scalable website audit for analysts using the cloud – Dev fest Hellas 2020

Enterprise websites split across many regions and locales are huge, but every page matters.

The solution utilizes a customized version of Lighthouse SDK and a BigQuery database for keeping track of results. Analyzing results is...

Web analytics & Privacy

Over the past couple of years, we’ve seen a lot of changes in web analytics and privacy. We saw the release of GDPR and CCPA, the rise of ad-blockers (both in mobile and desktop devices), several releases of Safari’s ITP, Mozilla’s ETP and announcements from Google on similar browser changes in the beginning of 2020. One thing is for sure, the way web analytics was working before is evolving. It does not look like the wild west anymore and there are several rules someone needs to keep in mind when setting up the tracking for a website/mobile app. It’s very...

CI/CD of online experiences using digital analytics

CI/CD of online experiences using digital analytics – Digital Analytics Meetup session

As part of the 17th digital analytics meetup, which I’m hosting in Thessaloniki, I held a talk on how to use common digital analytics tools to optimize the online experience of visitors. I wanted to show ways a digital analyst can utilize commonly used tools/services in smart ways, which go beyond what is advertised by the vendors. A mature, professional website starts its development cycle several months before its publication, but many may do not know that its development is completed shortly before it is replaced by its replacement (usually several years later). During its “life” there are constantly technical...
