SEO

Motivation

SEO matters because it gives teams a shared way to reason about the practice of improving a website so search engines can understand, index, and rank it for relevant queries.

Where it fits

SEO belongs to the product track and the Web Applications layer. It is useful when teams need to connect design decisions to practical engineering work.

Mental model

Think of SEO as a named pattern in the engineering map: it explains what problem is being solved, what boundaries are involved, and what tradeoffs appear when systems grow.

Common mistakes

• Treating the term as a buzzword instead of tying it to concrete behavior.
• Ignoring the operational, security, or product constraints around it.
• Learning the definition without knowing where it appears in real systems.
