Keyword Confusion

Hi, i have a simple question.

Im a little confused with my main keyword. My product page has a focus keyword like this:

"Word1 Word2 Word3 Word4"

This "keyword" in it self has no searches on google but,

"Word1 Word3 Word4"

Does have 12000 searches on google.
However

"Word1 Word4" does have even more searches on google than "Word1 Word3 Word4" does!

What im basically wondering about is: If i have "Word1 Word2 Word3 Word4" will this be just as good as only "Word1 Word4" as those two words are in the keyword now, or should i just change it to "Word1 Word4" since that one has the most views?

Sorry this is probably a hard read but if anyone understands please explain

Thanks in advance

i ill take 1234 it will give me more opportunity to drive traffic and there is a chance i might rank for word 1 word 3 and word 4 aswell, on the other hand it should make sense while all four words put together

Both. But a little bit more of "word1, word4"

You don't really need to use that much of a keyword to rank. Not being able to find what they hell you're looking for on Google proves this.

Okay Thanks! Ill go with 1234 and also a lot of 12 in contents etc And by the way 1234 does make sense together!

Yes, you should use 1234. It will give searches for 1 and 4 as well as for other 2 words. Also altogether they make sense, so it would be better.

Maybe it will be a reason to create pages for every word. It can give you a possibility to attract more traffic.
But I have a lot of examples when I use 1234 keywords on page and it works very well. So it depends on situation

You are doing the right thing which could rank you for different combinations.
