Check if your webpage URLs are SEO friendly. In order for links to be SEO friendly, they should contain keywords relevant to the page's topic, and contain no spaces, underscores or other characters.
You should avoid the use of parameters when possible, as they make URLs less inviting for users to click or share. Google's suggestions for URL structure specify using hyphens or dashes (-) rather than underscores (_). Unlike underscores, Google treats hyphens as separators between words in a URL.
