Links that require a click (like a navigation drop-down to view) are often hidden from search engine crawlers, so if the only links to internal pages on your website are through these types of links, you may have trouble getting those pages indexed.
Is there a way to optimize webpage formats that are pre-packaged? Would a drop-down menu from somewhere like Word Press or Square Space be harder to optimize because of my limited ability to alter them? Is it a good idea to include direct page links somewhere else to compliment the user experience of easy/flashy drop-down menus?
