# SEO starter basics

**Source and license:** Google Search Central, "Search Engine Optimization (SEO) Starter Guide", [developers.google.com/search/docs/fundamentals/seo-starter-guide](https://developers.google.com/search/docs/fundamentals/seo-starter-guide). Licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). This page is an AI-assisted summary by iinventedlight in its own words, not Google's guide itself.

## Summary
SEO means helping search engines understand a site and helping people decide to visit it from search results. Search engines mostly find pages by following links, so crawlable links matter most; a sitemap is an optional extra. Titles and meta descriptions shape how a result looks. Useful, original, people-first content counts for more than any technical trick. robots.txt and noindex keep pages out of search, and structured data can make pages eligible for richer results. Changes can take weeks to show.

## Facts
- id: F1
  claim: Google's crawlers find most pages automatically by following links from pages they already know. Publishing the page is usually enough. A site:example.com search shows whether a site is already indexed.

  claim: A sitemap is a file listing the URLs on a site that you care about. Submitting one is optional, and many content management systems make one automatically.

- id: F3
  claim: The crawler should be able to load the same CSS and JavaScript a visitor's browser does. If those are blocked, Google may not understand the page. Search Console's URL Inspection tool shows what Google sees.

- id: F4
  claim: Descriptive link text (anchor text) tells readers and search engines what the linked page is about. For links you don't trust, including links in user comments, add rel="nofollow" or a similar annotation.

- id: F5
  claim: Readable URLs with real words, such as /pets/cats.html, help people more than random IDs. On large sites, grouping related pages in folders helps Google learn how often each section changes.

- id: F6
  claim: The title element is a main input for the headline link in results. A good title is unique to the page, short, clear and accurate. The snippet under it usually comes from page text and sometimes from the meta description, which should be a short, page-specific summary.

- id: F7
  claim: Content that is easy to read, original, up to date and written for people tends to matter more for search than any other suggestion in the guide. Copying others' content does not help.

- id: F8
  claim: When the same content lives at several URLs, search engines pick one canonical URL. Redirect the extra URLs to the preferred one, or use a rel="canonical" link element if a redirect is not possible. Duplicate content is not a spam violation.

  claim: To keep pages or whole sections out of search results, use the supported opt-out methods such as robots.txt rules or a noindex directive.

  claim: Images should be sharp, placed near related text, and carry descriptive alt text in the img element's alt attribute.

  claim: Valid structured data on a page can make it eligible for special result features such as review stars and carousels.

  claim: Google Search ignores the meta keywords tag. Keyword stuffing breaks its spam policies. Keywords in the domain name, the TLD (outside country targeting), word count, heading order and E-E-A-T are not ranking levers to chase.

  claim: Search changes can show up in hours or take months. Waiting a few weeks before judging a change is a reasonable default.
