Be careful while structuring URLs

While Structuring URLs for a SEO there are also some do's and don'ts, which should be kept in mind to invite more audience. It's not that the slashes will necessarily harm performance, but it can create a perception of site depth for engines and users, as well as making edits to the URL string considerably more complex at least, in most CMS' protocols.

There's no hard and fast requirement—this is another one where it's important to use your best judgment.

The hash or URL fragment identifier has historically been a way to send a visitor to a specific location on a given page. Hashes can also be used like tracking parameters. Using URL hashes for something other than these, such as showing unique content than what's available on the page without the hash or wholly separate pages is generally a bad idea.

There are exceptions, like those Google enables for developers seeking to use the hash bang format for dynamic AJAX applications, but even these aren't nearly as clean, visitor-friendly, or simple from an SEO perspective as statically rewritten URLs. Sites from Amazon to Twitter have found tremendous benefit in simplifying their previously complex and hash/hash bang-employing URLs. If you can avoid it, do.

If you're hosting with Linux/UNIX, you can get into trouble as they can interpret separate cases, and thus randswhisky.com/AbC could be a different piece of content from randswhisky.com/aBc. That's bad biscuits. So be wary of case sensitivity.

In an ideal world, you want URLs that use the wrong case to automatically redirect/canonical to the right one. In the last few years, the search engines have successfully overcome their previous challenges with this issue and now treat underscores and hyphens similarly. Spaces can work, but they render awkwardly in URLs as %20, which detracts from the readability of your pages. Try to avoid them if possible.
