As mentioned with the rise of mobile, you don't want to make your pages too busy. Couple of other items:
1) My hosting/service provider offers an analyzer before you upload or change a page and their recommendations are at least 1 image and
outbound link on each page besides offering tips for SEO of the file name/keywords for that page. Altho, I don't believe with over 200 pages at my site that I should always offer an outbound link - still good advice overall.
2) Internal links are important, I give visitors at least 4-5 other click choices to keep them at the site.
3) I have created 10 rss feeds for specific sections of the site which bring in dofollow links. Some of these feeds are the most popular for visitors and a way of finding my site.
Happy Thanksgiving to our US friends!
