Would Rankings Be Affected With Trailing Slash In The URL?

By April

In episode 89 of our weekly Hump Day Hangouts, one participant asked about the effect of having trailing slash in URL on the rankings of a website.

The exact question was:

Hi Guys, I've got a question out of left field for you. I have a web designer who redesigned a site for a client, when they uploaded the new site it lost ranking, nothing new there it happens. But the client is pissed, and went out and got opinions on why. Here is what the clowns said. They said the url was built wrong with a forward slash on the end of url, and that was one of the reasons it lost ranking.
“If it ends in a “trailing” slash it creates a meta refresh http://your-site/catalogue/ that returns the error status 503 to the Googlebot.”

My first reaction is that they are full of shit. What do you think?
