SEO (search engine optimization) is the work you do to earn qualified visits from organic search results. The goal is not rankings for their own sake, but predictable traffic that converts.

If you want the one-line definition: SEO aligns intent, content, technical foundations, and authority so search engines can confidently recommend your page.

How search engines work (crawl -> render -> index -> rank)

Search engines do four things, in order:

1. Crawl: discover your URLs via links and sitemaps.

2. Render: load the page (often with JavaScript) to see what users see.

3. Index: store and understand the content (topics, entities, intent).

4. Rank: decide which pages best satisfy the query.

SEO breaks when one step fails:

The 3 pillars of SEO

1) Content (intent, depth, usefulness)

Rule: one primary intent per page.

2) Technical SEO (indexation and experience)

3) Authority (trust and defensibility)
