Most search engines have a 2,000–2,500 character limit on URLs. Although extended URL limitations are typical for many web services (especially social media sites), they are still troublesome.
The length of a URL has a significant impact on how user-friendly and readable it is. In the context of search engine optimization, a long URL may offer certain SEO benefits, such as cramming it with keywords, which will make them stand out and maybe increase its relevancy.
