Usage Guide for Banner Widget
You can choose to place one or more banners in any widget area, nofollow the links, choose to link to an internal page or an external URL.
Title: This is the title that appears at the top the widget. Check the ‘Show Title’ box if you want the title to appear on the live site.
Image URL: The URL to the image you want to appear for the banner like so: http://www.example.com/banner.jpg or http://www.example.com/wp-content/uploads/2014/06/banner.jpg
Image width (integer): Enter just the number portion of the image width. For example, 300 for 300px or 90 for 90%.
Image height (integer): Enter just the number portion of the image height. For example, 300 for 300px or 90 for 90%.
Size in pixels or percentages: Are the numbers you entered for width and height pixels or percentages?
CSS Class: Enter the CSS class that you want to apply to the banner. (Optional)
Alt: Enter the alt text you want for this banner.
Post Type: If you want to link to an internal WordPress post, page or other type, select the post type and click save to populate the ‘Page To Link To’ field with the correct internal items.
Page To Link To: If the user clicks on the banner, where should they be sent? You can select one of the items listed or use “Other URL” to send them to a custom URL. Don’t see the internal URL you want? Try changing the Post Type above to the correct item type for the internal URL and save the widget to refresh the list.
URL: If you selected “Other URL”, enter the custom URL here.
Nofollow this link: Checking this will add rel=”nofollow” to the banner link. This article by Google describes when you should and should not use the nofollow option.
