Duplicates & 301 Redirects - Not Working...

[chizzer]

Greetings.
We have several typical joomla duplicate pages, that are not complying with the 301 redirect and can not figure out why.

In the screenshot below - we are trying to redirect; start=10, start=25, start=15 to the main page 'amusement-articles'.

Redirect screen shot: Neither of these 301 options is working.

Is there anyway we can locate these three pages and delete them?
Thanks for time and assistance.

They are the same page.

'start' is a pagination parameter. It appears when there are more articles in the category then what's set to show in the Menu Item. start=5 will show the 5. article at the top.

Are you conserned about search engines? They are smart enough to figure it out on their own. Google Console had a setting where you could declare it as pagination, but was removed several years ago

Hello Mr.Berg.
Thank you for your kind response.

Yes, I realize they are the same page - something wonderful joomla is very good at.
And yes, I am concerned about the google, because these pages are being flagged as duplicate meta data. These same (3) pages are also noted as Dynamic urls.

I did not know this 'pagination' issue.
How do I set the menu item to reflect the amount of articles in the category properly?

Thanks again for your time.
