Let’s say I am targeting for the term “how to build a fire†and my site is named outdoorcamping.com. Should I direct the anchor link to my home page or to a sub page called outdoorcamping.com/how-to-build-a-fire/
In the case you described, you should definitely direct links to the subpage. You would be able to rank much better for that term with a page that is fully optimized for that specific term. Also you would want people to end up on that page and get exactly what they are looking for. If you direct people to your homepage for that search term, they may get frustrated trying to find that info on your homepage and give up to try the next search result.
