Magento

Is there a way to use underscores in the URL Keys for products instead of dashes?

From the backend Admin page go to:  System > Configuration

Go to the Catalog page

Under Search Engine Optimization change “Page Title Separator” from - to _

it didnt work for me fastmover. Do I need to refresh catalog rewrites?

Cheers for your help mate

did you find a solution for this? can you provide it?

Since the URL keys are used to create SEF friendly URLs, I prefer that all my competitors use underscores. It helps damage their SERP ranking.

Per Google, you should use hyphens for word separators in URLs. Google treats hyphens as word separators, similar to white space and allows links to help with keyword results. Underscores are treated as word joins or worse and can prevent the link text from contributing to optimizing the search engine results.
