By default, your Blog comes with two widgets: tags and archive. Your tags widget displays all the tags you've used to categorize your posts and your archive widget displays specific years/months of your blogging history. If you'd like to modify the settings of these default widgets, you can do so.
From the Site Builder, within the web pages section, click on your blog page.
Under the widgets section near the bottom of the page, click on new widget. There are 3 types of widgets: tags, archive, and html.
To display an archive of your posts, choose widget type, archive. You can then name your widget and select the format you want it to display in. You can choose drop down menu or list view. Most people utilize the list view so their readers can easily see the options available.
To display a tags widget, select the tags option under widget type. You can again name your widget and select the format you want it to display in. You can choose tag cloud or basic list. We recommend the tag cloud because it displays your most popular tags in larger text.
Make sure to click save changes after you select the settings for the archive or tags widget.
