Forced Trailing Slash on PHP Pages In Google!

[Webpresence]

Hi, have never seen this before so am hoping soemone can shed some light!

Google seems to be forcing a trailing slash at the end of our php pages within the search results.

For example, Google is indexing http://www.kingstoncabinets.co.uk/heat-convection.php/ (trailing slash) rather than http://www.kingstoncabinets.co.uk/heat-convection.php (without slash).

The trailing slash page doesn't display properly and has no page authority.

I've ran the site through Screaming Frog and there are no internal links the the trailing slash URL's, nor does there seem to be any external links to these pages.

Why is Google forcing the slash?

Am confused

Okay, here's a couple of things to look at first.

1. Rel Canonical: if you have  tags in your section, do they have trailing slashes?

2. What's in your .htaccess file (or web.config?). I just accessed the page without a trailing slash so this might not be the problem.

Lastly, I've just done site:kingstoncabinets.co.uk and I'm not seeing any trailing slashes, did you find the issue already?

Many thanks Martin, appreciate the feedback!

We've 301'd the following trailing slash pages to the non-slash pages so hopefully this should resolve the problem.

In answer to your questions;

1. No cononicals on the issue pages

2. No problems with the .htaccess file.

Am just confused why this has happened!

Thanks again, Lee

Looks like you've managed to fix the issue then, because your SERP listings seem to be without the trailing slash

Had you previously done 301's to the new URLs? Sometimes that can cause issues if the page structure is not the same on the new site as the old.

And just as a pointer, underscores aren't usually advisable for URLs any more, you're better using hyphens instead

Thanks Martin, not 301'd the pages before so it's still a mystery why this has happened! They're not new pages, been around for years without this problem!

We're aware of the underscore issue, this is how we found the URL's when we took over SEO, as the pages are ranking well I feel it best to leave as is.

Thanks again, Lee
