In a time when the referencing is especially known by strategies off-site of netlinking in particular, it is advisable to call back that it is also important to work the in-house SEO, that is to optimize correctly its pages and its internal links. The internal meshing is indeed a key factor of the referencing which can allow the site to climb much more easily on the SERP. Optimizing the internal meshing is before any improving the user experience and optimizing the links juice through all the site.
The first one of them is the simplest, but addresses especially websites with average size: websites possessing up to 50-60 pages can apply it in a effective way because it is a question of simply binding all the pages of the site between them . Watch out, not no matter how, it will be necessary to respect themes and anchors of links in adequacy with the subject and the page of destination.
We find then the technique said about the family tree, which divides into categories / subcategory / sub-subcategory pages and articles of the website. This technique finds its limits in the depth of the site, because in case this one would be too much under -categorified, risk to dilute the link juice too much becomes real. Thus here also, it is better to reserve this method for sites having less than 100 pages.
For medium-sized to big sites, it will rather be necessary to favor the 3rd and last technique, that from the internal linking in silo, which borrows the principle of hierarchical organization of the family tree while adding a semantic subdivision, which lends completely to assure a good experience to the Internet users and the relevance appreciated by Google.
This last strategy of internal linking owes its name to the structure of silos, reservoirs which we fill through the top used in the agriculture to store raw materials. In the case of websites, categorization and grouping of pages is similar, and is made on the same principle, as the funnel: the main category of a subject is referenced in each of the subcategories and the sub-subcategories, which allows to pass Pagerank and link juice in an increasing way by going back up in the categories.
In every time we go through a subcategory, we go to a more specific, sharper content. The architecture allows then to highlight effectively the main pages of your site and boost even more their referencing while bringing one convenience to the Internet user.
Every silo has to possess its own theme: in the end, thus the site finds itself with several silos of containing different theme / subject each several categories / subcategories. It is on the other hand advised to avoid as possible internal links between pages belonging to different silos, in order to keep a certain logic and a certain theme of contents to guarantee that the created internal links serve well to bring a further information, ideally in the objective to learn it more about the current page.
Today's SEO puts forward this semantization of the contents, the silo linking allowing to optimize the link juice of all its pages and thus boosts the positioning of these in the algorithm of Google.
An optimal internal meshing has to allow a given page to be connected with 1 - 5 other pages having the same subject or the same theme. To link more is not advised by a SEO point of view because it would begin to seem suspect: have you already seen on Web a "normal" page with more than 5 relevant internal links? If yes, it was probably either a media site, or a spam site with spinned and filled with keywords content.
Thus in less to fit into these categories, it is not really advised to exceed this figure.
The internal linking should not be necessarily made in the main text of a page, it can appear as well under the form of links at the generic anchors such "similar Subjects" or "IIn the same category". Attention however to well personalize and to vary anchors for every page! Whatever happens, they should necessarily be in connection with the page of chosen destination.
As regards our friend Google, beware of anchors over-optimization on your internal links. Indeed, if the Penguin filter is known to sanction too much optimized external links to the taste of Google's algorithm, it's the same for the too suspect internal links. Keep in mind that the keyword to choose its links anchors is "natural" Thus, Vary it and do not make an excessive use of optimization and others exact match keywords with the aim of rank better.
· Respect the 3 clicks rule: any page of your site must be able to be reached in 3 clicks maximum from the homepage.
· Over-optimizing internal anchors is an excellent way to receive a penalty from Google
· Avoid the nofollow for your internal links
· Vary at the most your anchors: a good internal meshing should not rest on the use of similar anchors or filled with keywords.
· Run away from the automated internal linking systems: Google spots them in a look and will relegate automatically your site to the very depths of the SERP.
· Make use of Internal.link to optimize your internal meshing, spy on your competitors ones, and boost your SEO rankings without risks !
