What are the objectives of SILO Site structure?
The
 first objective is obviously classified, compartmentalize the different
 semantic universe of a site to guide the ranking of the pages towards 
the body corresponding to the level of the index of search engines base.
Another
 essential point, in my opinion, it is the use of the semantic power of a
 same theme to optimize SEO from the pages of a silo, and mainly the 
landing page.
Probably
 the most important goal, it is the strengthening of the silo at the top
 by the optimization of the relevance of the internal linking on the 
landing page, from the lower categories of the silo.
The
 notion of theme is inescapable in a site built in silos, it is the base
 of the structure, so deepen the semantic scope of each silo through 
internal contextual links will allow no doubt contribute to the 
improvement of the listing of categories and subcategories of the silo.
In
 General, the structure of the silo is designed to increase the weight, 
the page rank of the pages contained in a silo but beware the mechanism 
does not in any way. The popularity, links juice 
must be transmitted through the top of the silo, so the landing page, 
down vertically and thus feed each page of the silo.
Somehow,
 partitioning a silo site, it of send a clear information and objective 
to the search engines on all the themes and keywords related to the 
site, saying that it is an easily interpretable language by robots and 
engines, even machine language did not succeed!
Implementation of the siloing - partitioning
Determine the themes and keywords of the site
The
 first stage of implementation of this architecture is to delimit the 
various semantic universes of the site, to highlight the silos.
If the site already exists, it may be interesting to analyze the statistics of it using web analytics tools.
Can
 then consider the impact of Google Adwords campaigns, but also 
highlight the essential keywords of the site, with powerful tools such 
as Ubersuggest, Google Trends, Nkini .info, Keyword Density. Thus, it will be easier to select queries that resulted in well to classify the site.
Once
 the essential keywords highlighted, any on-page optimization work must 
be made in order to find all of these keywords and their synonyms in 
each silo. It will therefore, integrate them at 
the level of each URL, for each category, subcategory, directory, title 
tag, header H1 - Hn.
All
 these actions will thus contribute to the strengthening of the semantic
 field of each silo and thus facilitate their ranking in the corpus of 
the base engine indexes.
Prioritize each silo
It must then organize the internal structure of each silo with a genealogical tree model. The
 elevator begins its Summit, by the category defining the general theme 
to break down into subcategories / sub-themes then possibly in 
sub-sub-categories, ending with the finest level detail articles.
Remember that it is better not to handle too many levels, you may increase the silo structure and complicate the robots crawl.
Reinforce the weight of the landing pages
The
 landing pages, entry points of each silo, with a very high weight, 
because at a level only of the home, is quite naturally these pages it 
will stiffen in order to provide a maximum of links juice and rank 
better in the search results.
The
 best solution for this, will consist in linker landing pages from the 
categories pages children or articles (level 3) through contextually 
rich links which will feed the semantic universe of the theme of the 
silo.
However, although very promising and beneficial, these links can be problematic during their implementation. Actually,
 most of the current sites abound in mega menus hyper accessible suits 
on every page of the site with links to all categories, subcategories, 
in short a bit too present navigation and a little in direct 
contradiction with our structure siloique, to place the famous 
contextual links loaded strengthen the landing pages.
There very fortunately some solutions to alleviate this problem. Not
 to mention the options javascript generally employed, it is possible to
 remedy through the anchors and ID html, you will find all the details 
in this article about multiple anchors, a very convenient way which will
 make possible the shortcut by crawlers link tracking because it will be
 simply different from the menu. You can also specify a different link and redirect it correctly on the landing page using a 301 redirect.
There
 are still another solution, if the previous do not agree, it is a 
technique that we had mentioned on the website Miss-Seo-Girl, concerning
 the strengthening of the internal mesh by the integration of pages 
tips, a technique that can be useful and that rid you permanently all 
these disruptive duplicate links.

Establishment of a structure of physical or virtual silos
If
 your site is new, not yet created, you can define the structure of your
 site entirely separating it by theme and thus to implement each silo / 
theme. In this case, you will implement the 
physical silos related directories, determined from the outset with 
categories landing pages created specifically for each of them.
This structure is clear and easily identifiable. On
 the other hand, if your site already exists and you want to implement a
 silo structure, you certainly need to implement virtual silos, an 
organization related to the concept of Theming. This
 technique is obviously more complex that the previous since each silo 
structure will be entirely created virtually from scratch. You will need to gather the pages of your site by topic, regardless of their category and sub-category where they are. Once
 this grouping by realized theme, you'll more than to determine the 
landing pages of each silo, the categories and articles. Finally,
 you will do to the strengthening of the landing pages through rich 
contextual links semantically from the base of the silo (subcategories 
or articles of level 3).
This virtual method is quite conceivable if we perform a detailed the new structure siloique conceptual scheme. The management of tags and keywords is also very largely inspired by this principle.
The
 main difference between the physical method (called directories) and 
the virtual method, is to the fact that in the virtual solution, the 
structure is only based on a set of links, while in the physical 
solution, pages are stored in separate directories.
Recommendations for a better structure in silo
But the most obvious and the most common error is that is to implement the links any azimuth between different silos. If
 some pages of content in a silo are linked to other pages of another 
silo, it is possible to bind the pages of each elevator landing, this 
action will be very beneficial for silos, it will not weaken and prevent
 dilution of the themes of each of the silos. You
 will contribute both to the respect for the integrity of each silo and 
the strengthening of the semantic weight of the landing pages. Links
 are important in a website in silo architecture and they are inbound, 
outbound, internal, if they are poorly managed, they can seriously 
affect the health of the site and therefore the positioning of the main 
keywords.
It
 was established that a minimum of 5 pages of content is necessary to 
anchor something in its theme and allow its ranking in the best 
positions.
One
 point that I had already explained in the structure of a site and that I
 remember again, it is essential to observe a level of depth of 3 or 4 
levels within each silo. Get more deep would result in a weakening of links, and therefore a loss of relevance of these pages.
It
 is absolutely essential to involve relevant content to links to 
strengthen the landing pages peaks of silos, without that the desired 
effect of optimization of the positioning unfortunately will not at the 
rendezvous.
To make optimal the silo structure, you must aim the 2 types of queries:
=> General keywords (short tail) representing the top of the silo
=> Keywords long tail representing the bottom of the silo
Conclusion
As
 you can see, this site architecture design can be very positive in an 
SEO strategy, in the same way as the technical design of a site to 
optimize, provided they follow a few basic rules that might be described
 as pillars of the siloique structure:
Architecture construction by theme
A reinforcement of the landing pages by links semantically enriched from the lower pages
Links between silos but from the top of each of them
