Excellent; I happened on this when - unusually - had a look at adsense forum.
Info applicable to content sites no matter whether concerned re Adsense.
I've lately made more effort re internal linking structure - figuring I have plenty of content, but can improve routes to various pages. (Yes, also adding more content; edit articles when I see need to do so.) WIll do more after reading post here.
I'd somehow missed re define: - looking into this.
