If you are using WP, there is a plugin that would allow you to build an interlinking structure within your blog respectively - you just need to specify the keyword/anchor texts, and the link that the respective keyword is supposed to link to (the primary/intended article).
Interlinking helps the search engine understand your content better, and that would allow them to better prioritize your content when listing them on the search engine.
Thus, when a specific keyword is linked to a specific article, it tells them that the targeted article is the relevant article for that respective keyword.
