URLs and SEO are closely tied.
Google ranks SEO largely based on links to and from your site, and changing URLs may cause the referring links to lead website visitors to error pages.
These broken links are going to hurt your referring traffic and your site’s domain authority.
Do vanity URLs affect SEO?
Traditional long URLs do have some advantage when it comes to keywords and SEO. However, the long format URLs are often lengthy and are not easy to share on emails, web pages, and especially social media services like Facebook and Twitter. Vanity URLs help to make links more manageable to share.
Does changing URL affect SEO?
Loss of SEO Ranking
Simple changes with your URL, such as, capitalization, adding a hyphen, an underscore, incorrect redirects, changing domain, etc. can have serious implications on your SEO. When any URL is changed, your organic search performance is going to change, which can be for the worse.
What are SEO friendly URLs?
SEO friendly URLs are URLs that are designed to meet the needs of users and searchers. Specifically, URLs optimized for SEO tend to be short and keyword-rich.
How long should a SEO URL be?
Shorter URLs are, generally speaking, preferable. You don’t need to take this to the extreme, and if your URL is already less than 50-60 characters, don’t worry about it at all. But if you have URLs pushing 100+ characters, there’s probably an opportunity to rewrite them and gain value.
