1. Describe your ContentA user should be able to make an accurate guess about the content of a web page simply by reading the URL. To accomplish this, a URL should include an accurate phrase or term that pertains to the page content.
2. Include Keywords in URLsIt is a best practice to optimize every web page around one keyword, and this keyword should be included in the URL. It is also important to put the most important keywords in the beginning of the URL, as search engine spiders do not give as much significance to words toward the end of a URL. Remember though, do not overuse keywords. Search engines recognize keyword stuffing and will penalize your website for those actions.
3. Use Hyphens to Separate WordsUsing hyphens to separate words in URL phrases is important to both user readability and search engine optimization. Google recommends using hyphens (-) instead of underscores (_) in URLs because hyphens are treated as spaces between words, while words connected by underscores are viewed as one word.

4. Use Lowercase Letters in URLsDo not use capital letters in your URLs. Search engines can decipher from uppercase and lowercase letters in URLs, which can lead to duplicate URLs and loss of page rank.

5. Keep URLs ShortThe URL of a web page should be as descriptive and brief as possible. A short URL is quicker to type and read. Also, the fewer the words the more value each word receives from a search engine spider. Too many similar words in a URL can be viewed as keyword stuffing and could result in a drop in search rankings.
7. Be Careful with Subdomains
It is important to consider that search engines have the potential to treat a subdomain as a separate entity from the primary domain. This can affect multiple aspects of SEO, including link building and trust value. Unless you have a specific reason to use a subdomain, it is best to use subfolders instead.

8. Limit Folders in URL StructureA URL should contain no unnecessary folders. Just use the amount of folders and characters that are needed for your URL structure. The flatter your site structure is the better.
Utilizing these best practices for SEO-friendly URLs should help your site rank higher in search results and entice users to visit your pages. A key component to URLs, and all aspects of SEO, is usability. Always keep the user in mind. One more thing to remember, Google likes to change the rules. Always keep your eye out for changes in the world of SEO.
