How many keywords to put in each Keyword Matrix cell?

[jessica.extension]

I'm currently developing a Keyword Matrix for my site, and i'm just wondering how many keywords I should be putting into each individual cell?

From what I learned in MOZ academy, each cell of the matrix will be turned into a keyword list. This means that if I only have one keyword per cell, I'd only have one keyword list that corresponds to each cell in the Matrix. Would it be wrong to include multiple keywords for each cell and thus, multiple keyword lists corresponding to each individual cell?

Thanks!

Hey there!  Melissa here, from the Learning Team.

The number of keywords that goes in each cell correlates to the number of keywords you're optimizing a page for.

You might ask yourself, "Well, how many keywords should I target per page?"  Unfortunately, there's really no hard and fast answer here. The number can be as low as 1 or as high as 15 or 20. You need to know which keywords have actual relevance to the page content, and it can get a bit tricky. Remember, focus on topic and concept, because that's what aligns with the Google Hummingbird update. The safe and generally effective bet is to choose one primary keyword that's specific and relevant to a page, with a decent monthly search volume, and then back it up with a few secondary keywords that are also very relevant, but aren't your primary keyword and may not have as high of a search volume.

Thanks Melissa! That helps a lot.

Would it be correct to say then, in general terms, each cell of the Matrix represents one page on your site? (Whether or not that cell has 1 or 20 keywords?)
