Northwest is also a correct spelling/term in some parts of the world (USA for example). Try that. Bing, for example will return North West and Northwest in a single search. (with a "did you mean North West?" underneath).

We don't usually discuss actual keywords at WW, but this is rather generic and does illustrate that some words and word pairs can be a single word with no hyphen requirement.

Thanks. That's a last resort if there's no alternative using markup.

Would there be any mileage in using a non-breaking space?

No - this would be treated as a word separator.

If you wanted to be particularly sneaky, you could do something like this:

<style>
.northwest {
 visibility: hidden;
}
.northwest:before {
 content: 'North west';
 visibility: visible;
}
</style>

<p>The <span class="northwest">Northwest</span></p>

Not sure it would be advisable, though!

For search engines like Google, this is a non-issue. If it's for your own search engine, however, you could consider using a data-* like <span data-alternate-spelling="northwest">North West</span> and index those.

For search engines like Google, this is a non-issue.

How so? Results are highly different for the two searches.

Are they? The differences are small for me. And in both cases it's all a jumble of "North West" and "Northwest". Google will know that it's sometimes spelled one way, and sometimes the other way. They're not treated identically, of course, but if you would only write "North West" you could still rank for "Northwest" queries. But I'm not sure Bunzer is referring to search engines like Google and Bing.

Yes, there are differences in the SERPs.

It really depends upon the inference, and that's the key point.

Is the page about the North West of a region, or something else.

If the page is about the region it should be all the other signals on the page that help point Google's understanding of what the page is about. It's the whole page that makes the difference of inference, not a single or split keyword.

I am referring to the main search engines and especially Google. The "North West" is a region of England in the UK. That is how it's usually spelt. I was just concerned that the words "North" and "West" were being given too much weight individually in SERPs. I suppose I shouldn't worry. The words are usually together, so they can be treated as a key-phrase too.
