SEO and search engine optimization is a space where technology must align with business goals. Pretty text alone is not enough - in my experience, it is the technical foundations that often determine whether a site will realistically start converting better. Fast hosting, indexing and optimizing database queries, compressing graphics (e.g. WebP) and implementing a CDN (Cloudflare, Fastly) usually have an immediate effect.
Google Core Web Vitals can suggest specific actions: minimizing CSS and JavaScript, eliminating render-blocking, proper server configuration (HTTP/2/3) and correct SSL. It's also worth taking care of HTTP headers, structured data (schema.org) and correct response codes - these are small things that are easy to overlook, but which affect crawling and indexing.
Analytical tools are effectively a decision map. GA4 and Search Console provide signals, and Screaming Frog, auditing and position monitoring tools allow you to verify them. Automated reports and alerts save time and allow you to react earlier than traffic drops become noticeable.
E-commerce companies have additional needs: optimization of product feeds (XML/JSON, correct GTIN/MPN type attributes), implementation of reviews in structured tags, correct internal search engine and integrations with price comparison sites (e.g. Ceneo, Google Shopping). The CMS should facilitate this - from friendly URLs and canonical addresses to automatic meta tag generation.
You'll learn how to run performance monitoring, set up analytics tools and automate repetitive optimization tasks. It may seem like a lot of technical stuff, but it's often the simple, technical fixes (server-level caching, image optimization) that have more effect than the subsequent content tweaks. If you want, I can also suggest priorities depending on size and business model.
