As the well-known expert Aaron Wall said in his e-book:
"Search algorithms rely heavily on internal linking structures to determine the importance of documents on your site. The pages that you link to most frequently are the pages you are telling search engines are your most important pages."
He also advised to use the words, for which we want to rank well, in the anchor text, when linking between our documents.
So, here's my question: do I have to pass through all the articles in my site (it's an online cultural guide, so it's quite big, really) and to put let's say 2-3 anchor links in each of them? Will there be any benefit for the site if I do all this hard work in interlinking my pages and does it worth it? If so, how could I see the actual results of my work?
I hope the topic doesn't become too messy...
