SEO internal linking best practices 2016
Types of links
A common link is usually composed of the primary domain (www.techindroid.com) followed by deep-link (deep link), which is nothing but the exact address of an entry into the main URL: http://www.techindroid.com/seo-strategy-get-started-improve-your-seo.html. If you do things right, the links on your page will be displayed as in the example. That is, at least, the cleanest way to locate content within a page.
It is also valid to include the date or category where the entrance is located www.techindroid.com/2016/07/seo-strategy-get-started-improve-your-seo.html or www.techindroid.com/seo/seo-strategy-get-started-improve-your-seo.html. While either of these two options is valid, internal link structure of a website my recommendation remains the last, because otherwise show dates tickets at some time or if you decided you wanted to re-locate an entry in another category, would have disastrous implications.
