Include notes or wireframes

As you go along, include any notes to yourself that you need to remember, such as cross-linking pages between sections or links to external sites such as Facebook.

You might find it easier to keep some notes in separate schematic drawings for certain pages. If so, go ahead and make some page wireframes (sketches) in addition to your sitemap. Tools such as https://moqups.com/, http://lumzy.com/, or Google Drive Drawings can create simple wireframes and are useful if you need to share your ideas or get approval from colleagues.

Once you have finished your sitemap and wireframes, have someone else look them over to sense-check. This could be a colleague or friend, ideally someone who fits your target audience.
