Content creators often overlook the importance of creating correct URLs, which can lead to broken links, crawl errors, and poor SEO. Using validated URLs that are easily legible to humans can help avoid these negative consequences. It's essential to collaborate with developers to create logical and organized URL structures that mimic content categories and subcategories. Crawlers like Google Spiders prefer simple URLs without multiple parameters, and using hyphens and underscores can make URLs more readable. The use of the trailing slash is not as critical for SEO purposes, but consistency is key. Utilizing broken link checkers can help fix errors and improve SEO.
