Multiple post categories - single permalink

I created a post which is assigned to multiple categories.

Eg: I have a post "My Post", and I put it in "foo" and "bar" categories.
Now my article will have two permalinks, "/foo/my-post" and "/bar/my-post".
Google calls this a duplicate, which it considers to be spam, hence this is not what I want.

How can I use multiple categories but have the same permalink?
I want this only for SEO.

My current permalink structure is /%category%/%post_id%-%postname%.html

It can't generate 2 URLs for a single post. If not specified otherwise will probably take the variable /category/ from your first category. Not duplicate content.

This is a common Wordpress behavior. I'm seeing this on most of the websites I've published with that URL structure - /%category%/%post_id%-%postname%.html

I have also read your comment, and if your post shows with different URLs, although unlikely, there's something wrong with your setup.

If you are using category name in permalink for a post, it's not a good practice, especially, if you have two or more categories per post.

Solutions: Use canonical link tag for the post and add it to your prefered absolute URL. Google will rank only this one and it won't be as duplicate content.
