Dynamic URL

A dynamic URL is a web address that is generated automatically by a server in response to a user’s request, rather than being a fixed, pre-defined address. Dynamic URLs are typically generated by content management systems, eCommerce platforms, or databases and often contain special characters such as question marks, equals signs, and ampersands that demonstrate the parameters used to generate the page.

A dynamic URL might look something like this:

www.example.com/products?category=shoes&colour=red&sort=price 

In contrast, a static URL is clean, fixed, and human-readable:

www.example.com/products/shoes/red

Dynamic URLs are common on large websites that pull content from a database (such as eCommerce stores, travel booking sites, and news archives), where it would be impractical to manually create a unique URL for every possible combination of filters or parameters.

Common causes of dynamic URLs include:

• Faceted navigation and product filtering on eCommerce sites
• Session IDs being appended to URLs to track individual users
• Search results pages generated by on-site search functions
• Tracking parameters added by marketing or analytics tools

Dynamic URLs can present a number of challenges for SEO. They can create large volumes of duplicate or near-duplicate content, as the same product or piece of content may be accessible via multiple URL variations. They can also waste crawl budget, with search engines spending time on parameter-driven URLs that offer little unique value.

Where possible, it is best practice to use clean, descriptive static URLs and to manage dynamic URL variations using canonical tags, parameter handling settings in Google Search Console, or by configuring your platform to rewrite URLs into a more readable format.
