Silo problem

Hey everyone,

Well I'm starting my new Amazon niche website and I have a small question about Silo that I couldn't found anywhere.
I want to use Silo Structure something like: http://pickmyshaver.com
Homepage will link to Categories through menu, Categories will be product types like in the example above: "Philips","Panasonic" etc and inside each category you will have product reviews and related articles.
My only problem is that I also want to target keywords like "How to use electric shavers right", I have alot of keywords like those and I'm not sure how to add them into my Silo.

They are not related to any of the categories but setting them up without a category will break the silo.

Any idea?

Have you thought of adding a category, maybe on the far left or far right, something like "Electric Shaver Tips"?

just add a category like mentioned above, tips/tutorials/useful tips

It's great by the way you're thinking about this. In my experience, a lot of site owners just throw content up on their site pell mell with no thought to organizing it. How you organize content is important, more now than ever before.

so just a blog category?
I also have articles like "best electric shavers under 500$"

Hello, I started to dig my site on Wordpress and I have some doubts/questions:

1. Some sources tell it is better to use Page/sub-page method, other sources say to use categories and sub-categories with Posts. Can you explain main differences with both metods? For example there is a plugin : https://wordpress.org/plugins/wp-no-category-base/ which will remove that annoying /category/ if this is the main argument to use pages but I just don't know exactly.

2. How you name your category pages AKA MAIN CONTENT YOU WANT TO RANK pages - exactly on www.domain.com/category-is-a-page OR www.domain.com/category/page(empty /category/ or content on /category/) ?

3. Is it ok to spam keyword in menu tabs which link to category/category page like: KEYWORD tips, KEYWORD quotes, KEYWORD songs? Isn't this an over-optimization?

Would be nice to get some clear answers

Sry for pumping old threads but the content related to structure shouldn't be time restricted

Is there a good way to make main category and sub category silo structure ?

A new category on hints and tips would be the right category for it.
