URL Hyphens

Checks that URLs use hyphens, not underscores

Severity	warning
Weight	4/10

Solution

Use hyphens (-) to separate words in URLs, not underscores (_). Google treats hyphens as word separators but treats underscores as word joiners. ‘blue-shoes’ = ‘blue’ + ‘shoes’, but ‘blue_shoes’ = ‘blueshoes’. This affects keyword matching and SEO. Replace underscores with hyphens and set up redirects from old URLs.
