It is important to plan your web site making sure your online needs are addressed.

Your needs may include:

Laying out the basic site including navigation.
Generating or obtaining any required graphics (including scanning and retouching of photo images).
Collecting any text from existing digital documents, through OCR (Optical Character Recognition by scanning documents and converting them to text), or manually creating the text.
Building the basic page templates to be used.
Integrate a database interface if required.
Build forms if required
Put all the pieces together (text, graphic, database interface, forms, etc...) into a great presentation that sells your site contents.
Proof and test all pages and forms in client specified browsers (i.e. Firefox, Google Chrome, Internet Explorer, Safari, Opera, etc...) This is an on going phase throughout construction.
