What is Indexing in Search Engines?
Indexing means that search engines store your web pages in their databases after crawling them. Once a page is indexed, it becomes eligible to appear in search results.
Key Features of Indexing
- Crawlability: Bots must be able to easily access your page.
- Content Relevance: The content should answer a user’s query.
- Structured Data: Helps search engines understand page layout and content meaning.
- Backlinks & Authority: Quality backlinks speed up indexing and raise priority.
- Sitemap Submission: Speeds up discovery of new and updated pages.
