E-commerce events in GA4 are the foundation of all analytics, and for e-commerce projects, it is specifically e-commerce events that allow tracking the full user journey — from product view to purchase. Unlike Universal Analytics, GA4 (Google Analytics 4) has no categories or actions — everything comes down to events with parameters. This is flexible, but requires correct implementation before the site goes live. If you don’t include e-commerce events in the technical specification or do it after launch — you’ll have to rewrite code, lose data, and waste time.

Website promotion is a set of actions aimed at increasing a website’s visibility online, attracting traffic, and turning visitors into customers. This is especially critical for e-commerce, where online store promotion directly affects sales volume and business profitability.

A Technical Specification for Website Development Is Not Just an Instruction for the Developer. When it comes to website promotion, this document must contain clearly defined SEO requirements: site structure, landing pages, technical indexing parameters, meta tag templates, CMS requirements, and responsive web design. In other words, a technical specification for SEO is part of the strategy that determines whether the site will be visible in search results, how quickly it will be indexed by Google, and whether it can effectively compete in the niche.

E-commerce (electronic commerce) is a sales format in which all stages of interaction with the customer take place online: browsing products, making a choice, payment, order confirmation, and delivery. Successful e-commerce brings together marketing, technology, logistics, and customer service — and all of that converges in one central hub: the website.

A technical specification for website development is a detailed document that outlines all the requirements for a future website: functionality, structure, design, integrations, responsiveness, SEO, analytics, and performance. It serves as the foundation for developers, designers, and marketers — and it determines whether the site will be not just "nice-looking" but an effective sales tool.

In 2025, competition in e-commerce has reached a new level. There are plenty of online stores, even more offers, and customer attention is shorter than ever. That’s why a product presentation is no longer just a “description + photo.” It has become a mix of UX design, persuasive content, website performance, marketing tools, and a deep understanding of consumer psychology.
