# Indexation

Indexing — the process by which a page is added to a search engine's database and made eligible to appear in search results.

**Indexation (Indexing)** is the process by which a web page is crawled by a search engine, added to its database, and made eligible to appear in search results.

Indexing steps:

1. **Discovery:** The crawler finds the URL (sitemap, internal link, external link).
2. **Crawl:** The bot downloads the page.
3. **Render:** JavaScript is executed, and the final version of the page is generated.
4. **Index:** The page content is analyzed and added to the index database.
5. **Serve:** It is shown in search results for relevant queries.

Factors that may prevent a page from being indexed:

- Crawl blocked by robots.txt
- [noindex](/content/sozluk/noindex/index.html) meta tag
- Canonical points to another URL
- Low content quality (thin content)
- Duplicate content
- JavaScript rendering error
- Server error (5xx)

**Tip:** The “Pages” report in Search Console shows the index status of your pages. Pages with the “Crawled – currently not indexed” status are usually held back due to a lack of quality signals; strengthening the content or increasing the number of internal links can help.
