Adding a New Page

The process of adding a new content page to your store is essentially the same for any type of page you might want to create. You can include text, images, blocks of content, variables, and widgets. Most content pages are designed to be read by search engines first, and by people second. Keep the needs of each of these two very different audiences in mind when choosing the page title, and URL, and when composing the meta data, and content.

The following instructions walk you through each step to create a basic page. Some advanced features are skipped over, but are covered in other topics.

OpenStep 1: Add a New Page

1. On the Admin sidebar, tap Content. Then under Elements, choose Pages.
2. Tap Add New Page.

4. To schedule design changes, expand  the Custom Design Update section. Then, do the following:

OpenStep 3: Complete the SEO Information

1. Expand  the Search Engine Optimization section. Then, do the following:

b. Enter a Meta Title for the page. The Meta Title should be less than seventy characters in length, and appears in the browser title bar and tab.
c. Enter your choice of high-value Meta Keywords that search engines can use to index the page. Separate multiple words with a comma. Meta keywords are ignored by some search engines, but used by others.
