I think that it might be seen as a pattern and something that is too focused.
I have lots of original articles related to the content of my site that used to carry lots of contextual internal linking. I removed the links a long time ago (pre-recent algo changes), I think because I realised they weren't that helpful to a vistor who, getting halfway through an article in which they are interested, would get whisked away to another page if they clicked the link.
I am however considering adding a final paragraph to the articles along the lines of "If you enjoyed this article about How to Ripen Fruit you may be interested in our selection of Green Bananas" with the last keyphrase linked to my green banana page.
This is helpful to the user, who has reached the end of the article, and helpful to me because it represents an appropriate "call to action" for a likely conversion to a sale. It is a marketing tactic, not (purely) an seo tactic. But is Google clever enough to spot the difference?
