Without this foundation, technical or editorialorial optimizations become patches with no overall coherence.

Keyword research remains the entry point. Queries are no longer limited to generic expressions at fort volume. You need to integrate :
- long-tail keywords, close to natural language and voice search;
- thematic clusters to build real "silos" of coherent content;
- local expressions if your activity depends on a geographical area.
To structure this work, specialized resources help save time. A guide like how to research keywords in SEO allows us to frame the method, correcisely exploit volumes and avoid making choices based solely on intuition.
