Embedded content is bad for visitors’ privacy and for long‐term content availability and archiving. “Sorry, we cannot display this document”, “Video deleted by owner”, “The image you are requesting does not exist or is no longer available.” “410 Gone” and “404 Not Found”. Does this sound like your web site?
Those images, videos, and PDFs that are embedded into pages and articles may be gone in a month or a year. If your site is not hosting the resources itself, it has no real control over the resources’ long‐term availability.
This is a plea to website owners and bloggers: Please host your own content!
When visiting old pages—in Internet terms that means anything published over one year ago—I often have no idea what the page is about. The page refers to a document, a video, a snippet of code, or something else that no longer exists. Whoever uploaded one or more of the referenced resources on the page have deleted it. Other times it is because a service that was the pinnacle of modern hosting and presentation at the time has since gone out of business. More often, some automated battleship of a bot fighting copyright‐infringement have mistakenly aligned its legal canons on your content.
Services change. The way it looks now is not how it may look in the future. Maybe you will not agree to how embedded videos from YouTube will be presented in nine months. You are likely to have absolutely nothing to say on the matter.
The only way to ensure consistent and continued availability is to host all content on your own servers. By doing so, you can ensure that some of the value is maintained over time. A back catalog of good quality content is increasingly important in these search‐driven times.
Privacy and who agreed to what?
What are the scripts you embed from third‐parties doing now? —and how about in six months? YouTube’s embedding code alone is 160 KB of scripts will full access to your site.
At some point, it does become easier and more manageable with self‐hosted content. You are in control of all the content now, and in five years from now.
Update : The General Data Protection Regulation (GDPR) went into effect in the European Union (EU) and the European Economic Area (EEA) earlier . The new regulation mandate that websites pay attention to privacy as discussed in this article. I believe this is a positive development!
