Answer: Search engine friendly URLs (website addresses) are URLs that don’t contain any cryptic letters or elements in them.
Examples
Un-friendly URL: http://www.juliankristian.com.au/?page=15
Friendly URL: http://www.juliankristian.com.au/blog/seo/what-is-seo/
Why use search engine friendly URLs?
It is considerably better to use search engine friendly (SEF) URLs for search engines as well as for users. They are easy to read and can express the content of your site. It’s really easy for visitors to remember your URL when you use SEF URLs, and they can help visitors identify where they are at on your website via the breadcrumbs path.
Another reason to use SEF URLs is that the URLs are shown in the search results. If you search for something in Google, the URL is displayed between the title and the description. If someone searches for one of the words in the URL, that word will also be bolded in the URL in Google.
