This wizard is a series of dialog boxes where you can add information that enhances your website’s visibility to search engines. If you have already added some of this information (for example in the Page Properties - Metadata dialog box), those screens do not appear.
Web Document - Author: Type your name or your company’s name.
Web Document - Internet search engine description: Add a brief description of your site.
Web Document - Internet search engine keywords: Add descriptive keywords that reflect the content on your site. Consider using synonyms of words in the content.
Page - Title: Your website can be more visible if you give each page a short, but descriptive title. The SEO Assistant shows this for each page in your document.
Image - Alternative HTML Text: Each image (and possibly multimedia file) on the page should have ‘alt text’ that shows if the file is not available. The SEO selects each image (or multimedia item) on each page in the document for you to supply alternative text. This text is also used with screen readers for visually impaired visitors.
