Avoid deeply nested URLs

Here are key reasons why URLs with multiple deeply nested subdirectories should be avoided:

Usability – Deep nested URLs long and difficult for users to understand, remember or share. For example, a URL like www.site.com/products/electronics/telelcd/brandx/32inch is overly complex.

Users prefer short, simple URLs they easily interpret. Engine Deep nesting tends to dilute the page relevance signals that help pages well. For page like www.site.com/products/item123456 may seem unrelated the topic “lcd tvs”, while www.site.com/lcd-tvsbrandx–inch is more clear. Keeping URLs short and topic improves ranking potential.

Link Similarly, concise URLs without deep nesting tend attract external links, as they are easier for other sites to visually parse and understand. Links to pages like: www..com/electronics/televisions/4k-tvs are cleaner in anchor text.

Site Architecture – Excessively nested URLs can point to issues with information architecture.

Often the same navigation and relationships between topics can be achieved with better URL strategies, using hyphens or segments that reflect major site.

Analytics – Deep nesting also leads to data analysis challenges. Pages buried deep may get lost in reporting, as tools like Google Analytics provide data for each subdirectory level. Keeping URLs shorter avoids diluting data.

Pagination – Paginated content like blog archives should avoid being nested too deep, as pagination strings like /page1/page2/page3 quickly get out of hand. Shallower nesting works better for in most cases.

Redirection Management – Every subdirectory increases the number of redirect rules needed when making changes to site architecture. Minimizing nesting simplifies redirect management.

In summary, the best URL structures tend to be relatively flat, with 1-3 short segments separating major sections of. This achieves usability, SE and analytics without overcomplicating URLs. While sometimes deep nest unavoid, in general aim for the shortest, simplest URLs using proper segmentation and descriptive keywords.
