16% of traffic still depends on HTM pages - 37000 page views/month
That's the big conclusion!
These pages are still based on the frontpage design that needs somehow to be fixed or updated.
While people can still watch the pages, the navigation is no longer coherent right now.
That's what needs to be either dropped (not worry about it as it only slightly affects the quality of the visitor's experience) or be put back on track.
To attach pages to a Dynamic Web Template In the Folder List task pane, select the file(s) that you want to attach to the Dynamic Web Template. To select multiple files, press CTRL and hold, and then click the files that you want to attach. On the Format menu, point to Dynamic Web Template, and then click Attach Dynamic Web Template. Locate and click the Dynamic Web Template you want to attach, and then click Open. If the body of a selected web page contains content, the Choose Editable Regions for Content dialog box appears. The dialog box displays the default settings for mapping content from the body of the web page to editable regions specified by the Dynamic Web Template. The Old column lists content in the body of the web page. The New column lists editable regions specified by the template. In the Choose Editable Regions for Content dialog box, do one of the following: To move all of the content in the body of the web page to the default editable region, click OK. If the default editable region contains content, that content is replaced with the content in the web page. To move all of the content in the body of the web page to a specific editable region, click (Body), and then click Modify. In the New Region list, click the editable region you want to move the content to. If you click (none), the content is removed from the web page. To maintain all of the content and structure of the web page, click Skip Current Page. The template is not attached to the page.
A Dynamic Web Template is an HTML-based master copy of a web page that you can create to contain settings, formatting, and page elements such as text, graphics, page layout, styles, and regions of a web page that can be modified.
You attach a Dynamic Web Template to the pages in a website, and that template defines the layout for those pages.
You can use any number of Dynamic Web Templates in a website, and you can attach a Dynamic Web Template to as many pages as you like.
----------------------
By using Dynamic Web Templates, you can create HTML pages that share the same layout. In addition to providing a shared layout, you can make some regions in a template available for editing while preventing changes to other regions in that template.
This means that you can allow others to add and edit content, yet still preserve the layout of the pages and the template itself.
