What does SEO mean?

Google's own starter guide puts it in one line: SEO "is about helping search engines understand your content" and helping users find your site (Google Search Central, read 1 November 2026). Wikipedia calls it the practice of improving how websites perform in search engine results pages (Wikipedia, read 1 November 2026).

The same guide is honest about limits: "There are no secrets here that'll automatically rank your site first in Google". And Google says it "doesn't accept payment to rank pages higher, and ranking is done programmatically" (Google Search Central).

How does SEO work?

Google says Search works in three stages, "and not all pages make it through each stage" (Google Search Central):

  1. Crawling: Google's crawlers find and download pages.
  2. Indexing: Google reads each page and stores what it is about.
  3. Serving: when someone searches, Google picks and orders the pages it judges most useful, on the search engine results page (SERP).

SEO work maps to those stages. Technical SEO makes pages easy to crawl and index. Content work makes pages the best answer to a search. Links from other sites, or backlinks, help search engines judge which pages others trust.

Why does SEO matter for B2B SaaS?

Buyers search before they talk to sales. A page that ranks for a problem you solve brings visits every month without paying per click.

SEO also feeds AI answers. For AI Overviews and AI Mode, Google says "a page must be indexed and eligible to be shown in Google Search with a snippet" (Google Search Central). Clicks are harder to earn: Ahrefs found a 58% lower click-through rate for the top-ranking page when Google shows an AI Overview (300,000 keywords, February 2026).

How do you do SEO?

  1. Find the searches your buyers use, with real search volume data.
  2. Make one page per main search, and answer it in the first lines.
  3. Make sure the page can be crawled and indexed. Check it in Google Search Console and Bing Webmaster Tools.
  4. Write titles and descriptions that match the search.
  5. Earn links and mentions from relevant sites. Google's spam policies list "Buying or selling links for ranking purposes" as link spam (Google Search Central).
  6. Update pages when facts change.

What does SEO look like? (hypothetical example)

A hypothetical example: a scheduling tool for clinics finds that "patient scheduling software" gets steady searches. Its homepage tries to rank for ten things at once. It builds one page for that search, opens with a two-sentence answer, adds a comparison table and a pricing section, and asks two healthcare blogs that already link to it to update their links. It then follows impressions and clicks in Search Console.

SEO vs GEO vs AEO

Generative engine optimization (GEO) aims at being named in AI-written answers. Answer engine optimization (AEO) aims at being the direct answer. Google's view is that optimizing for its generative AI features "is optimizing for the search experience, and thus still SEO" (Google Search Central). The difference is where the work happens: GEO and AEO depend more on third-party pages. The full comparison is in SEO vs GEO vs AEO.

How does SEO connect to third-party lists?

The "best X software" lists that rank in Google are also the pages AI assistants read. Prefer found that in July 2026, 40% of the sources cited for buyer questions were independent lists. A list that ranks well can send a buyer to you twice: from the search result and from an AI answer that cites it.
