Creating descriptive categories on your website and files not only make it easier for you to locate
your material but also for the crawlers to crawl through your site......
the url's you have should be friendlier for visiters

this type of url can give visiter a hard time to locate where he is on your website
whereas if your url have discriptive data, for eg . your website is about photography and your page's name is /learn photography .so it will be friendlier for your user as well as search engine.

if your website is about blogger tips and your domain name incude any of these terms or both terms . then whenever someone searches for blogger tips then your domain name or name of the document ,will be shown in google results in bold
google is good at crawling at any kind of url but it is better to make your url friendly
Other things to keep in mind
is not to make generic name pages for eg.. /page1.htm.
do not use nesting of subdirectories.
do not give excessive keywords in url.
two pages should not link to one page
allow visiter to get back to the previous page just by deleting the last text's of your url.
