URL: Query String

🛠️ What is a URL Query String?

A URL query string is a segment that appears after a question mark in a URL, containing key-value pairs used to pass information about the request. They are often used for tracking, filtering content, and session management. Example: 'example.com/page?search=query'.

⭐ Importance of URL Query Strings in SEO

URL query strings can significantly impact SEO by affecting crawl efficiency and causing duplicate content if not managed correctly. They can influence how a search engine interacts with your site, impacting its indexing and ranking.

⚙️ How Do URL Query Strings Work?

1. A user visits a website and interacts with features like searching or filtering, triggering a URL change with a query string.
2. The server processes the query string parameters to personalize or respond to the user’s request.
3. Search engines receive URLs with query strings during crawling and must determine if they should index them or merge them with canonical URLs.
