Do iFrames and Share Bars Help Retain Curation Traffic?

Many content marketers contemplating curation fear that linking to third-party content will drive visitors away from their branded properties to be never seen again.  One tactic employed by some marketers is to use a share bar or iFrame which hovers over the third-party article displaying branding and a link back to the site which curated the content.  

Share bars must be used with caution. While they may help decrease attrition from a curation site, they also can annoy readers, visitors, and even search engines if they are not used with caution.  Let’s review some aspects to consider when deciding to use a share bar from marketing, reader, publisher and search engine optimization perspectives.

How to Bust Out

If you find that your content is being wrapped in a share bar or iFrame, and don’t want this, there are two ways to bust out.

The easiest and most practical way is to simply put a small piece of JavaScript code on every page of your site.


if (top != self) { top.location.replace(self.location.href); }


This basically tells the browser that if your page is not in the address bar, then reload the page without any iFrame wrappers.  This should work 99% of the time, but it is possible to circumvent this iFrame buster.

A better fail-safe way is to use a newer HTTP header called X-Frame-Options.  This will require IT help.  Furthermore, X-Frame-Options don’t really bust you out of iFrames, they just instruct the browser not to render your page if it detects it is being iFrame’d.
