That's a really well and detailed guide. Good Job slpishslpash.
What do you think about creating a website with multiple pillar articles and adding supporting articles for every pillar article.
Like this:
tombelfort.com - this will be the homepage where will be displayed 5 static pillar articles (for example).
first pillar article: tombelfort.com/best-electric-shavers-for-men
supporting articles:
tombelfort.com/best-electric-shavers-for-men/product-review1
tombelfort.com/best-electric-shavers-for-men/product-review2
second pillar article: tombelfort.com/best-electric-shavers-for-women
supporting articles:
tombelfort.com/best-electric-shavers-for-women/product-review1
tombelfort.com/best-electric-shavers-for-women/product-review2
third pillar article: tombelfort.com/electric-shavers-tips
supporting articles:
tombelfort.com/electric-shavers-tips/how-to-shave-hair
tombelfort.com/electric-shavers-tips/how-to-speed-your-shaving-process
Then we will have 3 pillar articles (with 3 silos) with the main keywords we want to aim and some supporting articles for each pillar article. In this way, we will build links only to the pillar articles.
Isn't better for the link juice passed to have more silos for every main keyword we aim like this structure?
In this way, the main keywords (pillar articles) will be very close to the fundation of site (the homepage)
What do you think about this?
That's not a good structure.
First of all, I know this is only an example, but remember, don't have spammy looking stuff in the url like "best-electric-shavers". That's fine for the title and/or h1, but for your urls keep it clean and topical, like "mens-shavers/blah" or "electric-shavers/blah"
Siloing is about topical relevance, not keyword relevance. Never create a silo for one keyword

You shouldn't even create an article for one keyword let alone an entire silo.
A 3000 word "best electric shavers for 2016" type article will rank for 100's of keywords. 200-900 and that's without siloing.
You silo based on logical topics.
Animals
Dogs | Cats
Breeds, puppies | Breeds, Kittens
German Shepherd, Border Colie | Training Your Puppy, Teaching Your Puppy Tricks || Siamese, Burmese | Litter Training Your Cute Kitty | Why Kitties Are Better Than Puppies --
So you'll have
animalsite.com/dogs/breeds/german-shepherd/some-article
animalsite.com/cats/kittens/litter-training-your-cute-kitty
That looks nice. It's logical. It's easy to navigate and it builds topical relevance in sub-areas, which each build up relevance in the parent area.
You would not do this :
Animals
Best Way to Train Dogs | Best Way to Train Kittens
Supporting dog articles | supporting cat articles
That's awful and it'll look like
animalsite.com/best-way-to-train-dogs/
animalsite.com/best-way-to-train-dogs/teaching-your-puppy-tricks
You aren't building any topical relevance anywhere like that.
'best shavers for women' is not a topic. At best you're building topical relevance as a review site.
You're sort of building topical relevance for womens shavers, but, when you have another silo side by side with electric-shaver-tips you just end up with a big mix of topics and repeated content. Google doesn't like repeated content. It will only choose one page on your site for groups of keywords.
You wouldn't try to rank site.com/best-electric-shavers" and "site.com/shavers-for-men", which is almost what you're doing. I wouldn't even have a page for womens shavers the way you've done it.
In this example best electric shavers for women only has 600 searches a month, so either putting it in your main best shavers article, or just creating a "best electric shavers for women" article within the silo.
All your money pages don't have to be pillar pages.
But, let's say electric shavers for women is big, and gets 2000-3000 searches+ with lots of 500-1000 LSI's
You could do
electric shavers
womens | mens
site.com/electric-shavers/mens
site.com/electric-shavers/womens
with the actual pillar article title being "Best Electric Shaver for Men|Women"
The reason I don't like best in the url is because it makes your supporting articles look spammy
site.com/electric-shavers/best-for-men/how-to-clean-your-shaver
looks awful
site.com/electric-shavers/mens/how-to-clean-your-shaver
looks good.
So in summary.
DO NOT SILO KEYWORDS OR KEYWORD GROUPS!
Siloing is for TOPICS only.
