I have a few small review sites that have around 5-10 top 5 review articles on them. The homepage is my main keyword which is also a top 5 article and the pages in my nav bar are the standard about us, blog, contact ect... I have no sidebar to cut the keyword density down and I also think it looks better. My question is how should I interlink the review articles with no sidebar? Should I use contextual links on the homepage to all of the reviews and then use random links in each individual article? Please share what you would do.
