[wp-hackers] category URL's and SEO ranking

[Haluk Karamete]

When you keep the category base ( that is you don't remove it by a
plug in) WordPress does allow you to browse to your 2 level deep
category in two different ways as the example below would demonstrate
it.

say, your category has a top level item "MULTIMEDIA" and a child under
it called VIDEO.

Visually, we are talking about a situation like this;

Category taxonomy

multimedia
    video
    audio
topics
    science
    politics
Well, you may get to that child (video) in the following 2 different ways;

yoursite.com/category/multimedia/video or yoursite.com/category/video

The point here is that WP brings you to the exact same page,
regardless of which URL has been used, and there are no redirects here
neither, so both URL's remain on the visitor's browser as is just like
it was requested at the first place. And with either URL, the
resulting content is identical.

That's a hateful situation by Google.

Google punishes such sites cause your web site got the same exact
content appearing under 2 different URL's. ( This is of course when
you happen to use both URLs. ) Sure, Nobody would want to do that
deliberarely but sometimes you end up with that. And this question is
all about that case.

Let's say, you wanted to pick the simpler URL for your VIDEO category
and you want to stick to that only. Basically, you want the URL to be

yoursite.com/category/video

This is easy to achieve when you use the custom menu feature that
comes with WordPress where you can specify a URL for that particular
custom menu item of yours. So, when visitors click on the VIDEO link
on the custom menu, they end up coming to

yoursite.com/category/video

No problems so far...

But as soon as they pick a post out of that category, and they end up
coming to a post where the post's meta data displays things like
"CATEGORIZED in" or "TAGGED by" etc, they will be exposed to the
alternative URL for that VIDEO category.

So, if a user clicks on the VIDEO link in the "Categorized in" area,
the URL that they will end up with would be

yoursite.com/category/multimedia/video

And with that, there goes your SEO ranking.

My question is what techniques do you use here so WordPress always and
always use one single URL, the URL you defined in the custom menu.

I thought, category slugs could do this, but when I checked it, slug
feature allows me to change only the category term in the URL, not the
path to it.

If it were to give me a choice like

video slug: /category/video

I would be done.

But that choice is not available at this moment. When you do that, you
end up with the following slug instead

categoryvideo

That's because / is not a valid character for a slug.

Please suggest an alternative way to tell WordPress to stick to
/category/video at all times.

Before suggesting the obvious, ( well, just skip the 'multimedia' and
make the 'video' a top level cat. ), let me say that that suggestion
won't work for our situation.
