What is SEO and how does it work in 2026?

Nova

Google does not reward whoever repeats a word the most. It rewards whoever answers the question best.

Quick answer

SEO (search engine optimization) is the work of making Google and other search engines find, understand and show your site when someone searches for what you offer. It covers the technical side (the site can be crawled and indexed), useful content and the reputation the site earns over time.

How does Google decide what to show?

First it crawls your site, then it indexes it (stores it and understands what it is about) and, when someone searches, it picks the pages that answer best. If any step fails, your page does not show up, however good it is.

What does Google recommend to get started?

Google’s official starter guide sticks to the basics:

  • Help Google find your content, for example with a sitemap.
  • Organize the site with descriptive URLs and grouped topics.
  • Create original, useful, well-organized, up-to-date content.
  • Add quality images with descriptive alt text.
  • Promote the site so people discover it.

What no longer works?

Stuffing pages with keywords, filling the keywords meta tag (Google Search does not use it) or publishing text written for the search engine instead of people. Google says its systems prioritize helpful, reliable content created for people.

How is SEO measured?

Search Console shows which searches you appear in, how many clicks you get and which pages have issues. What ultimately matters is not rankings but how many leads and sales come from organic search.

Frequently asked questions

How long does SEO take to work?

Technical fixes show up within weeks, but organic rankings usually take months and depend on your industry’s competition.

Do Google Ads improve SEO?

No. Ads and organic results are separate systems.

What is the difference between SEO and AEO?

SEO aims to rank your page in results; AEO aims to make your content the source of an answer in search engines and AI assistants. They share the same foundation.
