Ba conteaza si URL-urile SEO/user-friendly:

Creating descriptive categories and filenames for the documents on your website can not only help
you keep your site better organized, but it could also lead to better crawling of your documents by
search engines. Also, it can create easier, "friendlier" URLs for those that want to link to your content.
Visitors may be intimidated by extremely long and cryptic URLs that contain few recognizable words.

Some users might link to your page using the URL of that page as the anchor text. If your URL
contains relevant words, this provides users and search engines with more information about the
page than an ID or oddly named parameter would.
Tot oficial de la Google.

Iar din experienta mea, URL-urile bine scrise pot creste considerabil traficul unui site.
