    6972== Frequently Asked Questions ==
    … …  
    7174= What if the web page I'm syndicating has relative URLs? =
    7275
    73 The plugin does its best to convert relative URLs into absolute http://... URLs so images will display and links will work and relevant CSS and JavaScript files will be imported.
     76Unless the content is published in an iframe, relative URLs from an external site will not work. Neither will relative URLs published from your own site when the relative directory is different than where your WordPress page is displayed.
    7477
    75 = I see an advanced feature is to publish with JavaScript. Why would I want to publish content with JavaScript? =
     78If links and external content (like images) need to work, the URLs of the href and src attributes need to be absolute https:// or https:// URLs - unless, as noted, the content is published in an iframe where relative URLs are relative to the URL of the content rather than the URL of the WordPress page.
    7679
    77 To discourage robots and spiders from reading the syndicated content. It may be desirable to keep ads out of search engine indexes, for example, and perhaps also off-topic content so SE's do not come to wrong conclusions regarding a page's topic.
     80= Why would I want to convert content into JavaScript before publishing it? =
     81
     82One reason for using this optional feature would be to discourage robots and spiders from reading the content. It may be desirable to keep ads out of search engine indexes, for example, and perhaps also off-topic content so SE's do not come to wrong conclusions regarding a page's topic.
     83
     84= What would importing live JavaScript do for me? =
     85
     86Some ads are delivered with JavaScript. Some regular content, such as the Spam-free Form, are delivered with JavaScript.
     87
     88There are developers who have determined that syndicated or remotely delivered content provided as JavaScript is desirable because it makes their content accessible by more websites - as compared to requiring specific types of web pages, like PHP (for example).
     89
     90As with all content pulled in from remote websites, not only JavaScript code and not only into WordPress, there must be trust that the provider won't send nefarious content or code to your page. Otherwise, it may be prudent to just not do it.

     28The plugin is especially useful when you have more than one WordPress installation, perhaps on several domains. Common content across each installation can be pulled in with the URL of one central file - contact information, special sales, political notices, daily quotes, any content can be provided by a central file or script.
    2629
    27 Advanced features include the ability to insert the content as JavaScript (to discourage spiders/robots from reading the content) and the ability to insert plain text content with optional CSS formatting.

    6972== Frequently Asked Questions ==
    … …  
    7174= What if the web page I'm syndicating has relative URLs? =
    7275
    73 The plugin does its best to convert relative URLs into absolute http://... URLs so images will display and links will work and relevant CSS and JavaScript files will be imported.
     76Unless the content is published in an iframe, relative URLs from an external site will not work. Neither will relative URLs published from your own site when the relative directory is different than where your WordPress page is displayed.
    7477
    75 = I see an advanced feature is to publish with JavaScript. Why would I want to publish content with JavaScript? =
     78If links and external content (like images) need to work, the URLs of the href and src attributes need to be absolute https:// or https:// URLs - unless, as noted, the content is published in an iframe where relative URLs are relative to the URL of the content rather than the URL of the WordPress page.

    77 To discourage robots and spiders from reading the syndicated content. It may be desirable to keep ads out of search engine indexes, for example, and perhaps also off-topic content so SE's do not come to wrong conclusions regarding a page's topic.
     80= Why would I want to convert content into JavaScript before publishing it? =
     81
     82One reason for using this optional feature would be to discourage robots and spiders from reading the content. It may be desirable to keep ads out of search engine indexes, for example, and perhaps also off-topic content so SE's do not come to wrong conclusions regarding a page's topic.

     84= What would importing live JavaScript do for me? =
     85
     86Some ads are delivered with JavaScript. Some regular content, such as the Spam-free Form, are delivered with JavaScript.
     87
     88There are developers who have determined that syndicated or remotely delivered content provided as JavaScript is desirable because it makes their content accessible by more websites - as compared to requiring specific types of web pages, like PHP (for example).
     89
     90As with all content pulled in from remote websites, not only JavaScript code and not only into WordPress, there must be trust that the provider won't send nefarious content or code to your page. Otherwise, it may be prudent to just not do it.
