URL Parameter

A URL parameter, also known as a query string, is text added to a webpage's URL to track or filter content.

Definition

URL parameters are snippets of text added to the end of a website's URL, usually after a question mark (?), to manage and track content on webpages. They are often used for sorting, filtering, or tracking purposes on websites. Parameters can specify the content a user wants to see or help website owners track user behavior and campaign performance. By altering these parameters, the same webpage can show different content or track how visitors access the page.

Did you know?
Google can use URL parameters to index pages more efficiently, recognizing session IDs or sorting information that doesn't change the content of the page.

Usage and Context

URL parameters are crucial in SEO because they can significantly impact how search engines crawl and index web pages. Properly managed, they help search engines understand which pages are important and how to prioritize them. However, if not handled correctly, they can lead to duplicate content issues, waste crawl budget, or decrease a page’s visibility. For example, if an e-commerce site uses parameters for tracking session IDs or sorting products, these can create many URLs with similar or identical content that could confuse search engines.
