One of the simplest ways to improve site overall SEO is to have SEO-friendly URLs.
According to Google: “A site’s URL structure should be as simple as possible. Consider organizing your content so that URLs are constructed logically and in a manner that is most intelligible to humans.”
So SEO-friendly URLs are URLs that are easy for both visitors and search engines to understand.
They are important for SEO because search engines use the webpage URL to understand what your content is all about.
Now to create SEO friendly URLs, you can follow these steps:
- Keep URLs focused
- Keep URLs short
- Keep URLs formatting consistent
- Use relevant keywords
- Avoid special characters
- Avoid numbers
- Separate words using hyphens
While short URLs are recommended, there's no hard limit on how long a URL should be ... short URLs are recommended because they're mostly more focused.
For example: our keyword is "keyword research," and the page title is "Step by step guide to do keyword research," then the SEO friendly URL structure will be:
Also, changing the URLs of existing posts/pages isn't a good idea as that can do more harm than good. So apply these recommendations to new posts and pages only.
