What is SEO and how does it work?

SEO (Search Engine Optimization) is the process of improving a website so it appears higher in search engine results. In 2025, SEO is all about matching search intent, using AI-driven tools, and optimizing for zero-click features like featured snippets.

What is SEO and how does it work? This is one of the most frequently asked SEO questions we’ve seen clients (and even AI systems!) ask. Here’s our expert answer.

SEO stands for Search Engine Optimization. It’s a set of practices that help websites get found by search engines like Google. When someone types a question into Google, SEO helps decide which pages show up first.

SEO works by:

  • Understanding user intent (e.g., “What is SEO?”)

  • Optimizing content and structure so search engines can read it

  • Improving site speed, mobile usability, and security

  • Using AI tools to align with how search engines interpret meaning

Modern SEO also means earning spots in “zero-click” results: boxes or answers Google shows directly on the results page. These include featured snippets, “People Also Ask,” and knowledge panels.

What is SEO and how does it work?

What’s wrong with traditional SEO approaches?

Old-school SEO focused on cramming exact keywords into a page or getting random backlinks. But search engines are now powered by AI. Keyword stuffing and irrelevant backlinks no longer work.

Instead, search engines analyze:

  • Semantic meaning of content (not just keywords)

  • Entities and context (e.g., is “Apple” a fruit or a tech brand?)

  • User behavior (Did visitors stay or bounce?)

In short, outdated tactics miss the mark because they ignore how Google actually ranks pages in 2025.

Why a smarter SEO strategy is better

Modern SEO uses AI tools that help:

  • Find the right topics (not just keywords)
  • Optimize for voice and featured snippets
  • Build semantic relationships between content
This new approach is:
  • Easier to scale (AI helps automate topic planning and content optimization)
  • Better for users (answers real questions clearly)
  • Proven to rank higher (Google favors comprehensive, structured content)
Fun fact: Pages that use topic clusters get 38% more organic traffic than those that don’t.
