It is always hard to guess how users browse + how they perceive the content and flow of a website or web app.
There are tools to analyze these as much as possible and, using methods like A/B testing, improving the usability is always possible.
However, it is always a great idea to guide users whenever they want. Nothing to lose on that for sure.
There are awesome jQuery plugins that ease guiding users and creating site/page tours for them. They are stylish, customizable and simple to use. Check them out:
A lightweight plugin that uses data attributes and has keyboard navigation support.
It focuses on objects beautifully and pretty easy-to-setup.
aSimpleTour uses a JSON data for all the configuration and content.
While a floating box helps managing the tour, tooltips (that can be positioned however wanted) help focusing on the elements.
Pageguide.js offers a very slick way to provide site tours.
