Double Slash // in URL

[yanaiguana111]

My client is using double forward slahes in URL like this "//" is this affecting SEO?

Double slashes means that if you are on a https page, the links will be https. On http pages, links will be http. Its most commonly used when you have a sitewide include and want some pages to be https compliant without sourcing the https on http pages.

As long as there isn't a https AND http version of the same pages, you should be fine.

Thanks Oleg, I should have pointed out that it's not after http:// but rather in the URL itself:

Example: http://brandname.com/folder//article1//article2

[OlegKorneitchouk]

Ah. That's probably just an error. The same page should load at http://brandname.com/folder/article1/article2.

I would remove the extra /, update all the links to the pages and set the proper canonicals.
