What Is Indexing?
Indexing is the process by which search engines add web pages to their database (index). When a page is indexed, it can appear in search results. When a page is not indexed, it is invisible to searchers regardless of how good its content is.
How Google Indexes Pages
- Googlebot discovers a URL (via links, sitemaps, or direct submission)
- It crawls the page and reads the HTML content
- It analyses the content — title, headings, text, links, images, structured data
- If the page meets quality thresholds, it is added to the index
- The page can now appear in search results for relevant queries
How to Check If Your Page Is Indexed
- Search

- Use the URL Inspection tool in Search Console for specific pages
Common Indexing Problems
| Problem | Cause | Fix |
|---|---|---|

| Page discovered but not indexed | Low quality or duplicate content | Improve content, add canonical tag |
| Slow indexing | No sitemap, poor internal linking | Submit sitemap, add internal links |
| Page dropped from index | Content removed, server errors, penalty | Restore content, fix errors, check Search Console |
