For context, the sole purpose for this add-on is to improve the embedding of third party content. Amazon product links can be converted into nifty little product widgets that look better than just a text URL, so that's what it does. In fact,
the first version of this process (circa 2014) didn't even support affiliate tags. I added support for configurable affiliate tags shortly after.
Some time ago, I started received reports of admins and/or users that complained that they couldn't see embedded Amazon product widgets on account of some adblocking and/or privacy enhancing feature, either built-in or as a browser extension. The irony of complaining that an adblocker configured to block Amazon content was, in fact, blocking Amazon content wasn't lost on me but I also know that many users install extensions without knowing what they really do. That's why I devised a minimalistic solution, in the form of a placeholder that would fill the space reserved for the product widget (which would otherwise remain blank) without disrupting the page layout. The placeholder links to the product page in case the user wants to access the page but doesn't know how to disable their adblocker, and it carries an affiliate tag (if applicable) so that the webmaster doesn't lose revenue. More recently, browsers and extensions have become increasingly
thorough in blocking content, by misrepresenting that a page has been loaded when it's been in fact blocked or redirected, or by misrepresenting an element's dimensions, position on the screen, or visibility in general, and I have updated the placeholder accordingly. However, I do not want this feature to turn into some sort of adblocker-blocker if users configure their browser to hide some type of content.
With that said, if your goal is to optimize affiliate links and other extensions work better with untouched URLs, then you can edit the Amazon media site and check the box that says
Do not auto-embed links from this site
. It will preserve the existing embedded products, but it won't transform textual links in future posts.
I installed this add on a year ago
But quite frankly I can't see any difference.
What kind of effect did you expect, that failed to materialize?
