E-commerce knowledge base
Research, reviews and practical breakdowns: what works in online stores, how to measure change and build a sales system.
Vibe coding
Vibe coding is building programs where a person describes the task in ordinary language, AI writes the code, and the person accepts the result almost without checking it and goes by whether it "looks like it works", adding new wishes in the chat. For quickly…
Customer surveys
Customer surveys are short questions to customers about their experience (why they bought, what they couldn't find, how delivery went) that give a store what numbers don't show: reasons. Analytics shows where people stop, a survey helps you understand why.
Cash on delivery and unclaimed parcels
Cash on delivery is a payment method where the customer pays for the order when receiving the parcel, and the carrier passes the money to the seller. An unclaimed parcel is when the customer did not pick up the parcel or refused it, and the goods go back to…
Session recordings and heatmaps
A session recording is a replay of how one visitor used a site: where they moved the cursor, where they clicked, how they scrolled. A heatmap is a summary of such actions by many visitors on one page: where they click and how far they scroll. They show what…
Google Consent Mode v2
Google Consent Mode is a way to pass a visitor's choice from the cookie banner to Google tags (Analytics, Ads) so they behave accordingly: without consent they don't set cookies and don't send data that requires permission. Version 2 added two parameters for…

LTV (lifetime value, also CLV or CLTV) is the amount a customer brings to the store over the whole time of the relationship. For management decisions it is better to calculate it not in revenue but in margin: how much money the store keeps from all of the…
Online store catalog structure
Catalog structure is how products are arranged into categories, subcategories, filters and page URLs. It answers two questions: can a customer find what they need in a few clicks, and does a search engine understand which pages matter.
Server-side tracking
Server-side tracking is a setup where data about events on the site (a view, the cart, a purchase) is sent not straight from the browser to Google, Meta and other services, but first to your own server, and from there passed on under your rules. In Google Tag…
The mobile version of a store
The mobile version of an online store (mobile UX, m-commerce) is how the site looks and works on a smartphone: from the catalog and search to checkout. Mobile traffic in Ukraine is large: by recent data, about 60-78% of online purchases are made from a…
RFM analysis
RFM analysis is a way to segment customers by three attributes: how recently they last bought (Recency), how often they buy (Frequency) and how much they spend (Monetary). It shows who to write to first and who has, it seems, already been lost.
Hosting, CDN and traffic peaks
Hosting is the server (or cloud) the store runs on. A CDN (content delivery network) is a network of servers around the world that serves part of the site (images, scripts, sometimes pages) from a point closer to the shopper. Together they determine whether…
Cookie banner
A cookie banner is a window on a site where the visitor accepts or declines cookies and similar technologies that are not strictly necessary. For visitors from the EU this choice has to be offered before the site starts setting analytics and advertising…
