ViDL is a free Mac app that allows you to easily download videos from YouTube and hundreds of other websites for offline viewing.
It is based on the popular youtube-dl command line tool, but much easier to use, especially with videos/playlists that require a login (like your personal "Watch Later" list).
ViDL includes a browser extension for Safari, and a bookmarklet for other browsers, so you can download a video directly from a page you're viewing.
Some videos or playlists require a login before you can view or download them. ViDL can use login sessions (cookies) from an integrated web browser, so you can log in to e.g. YouTube to download your personal Watch Later list, private videos, etc.
You can easily download entire playlists from YouTube (just enter the playlist URL), or pick and choose from the list of thumbnails.
ViDL can optionally extract the audio track from any video you download (or, depending on the website, only download audio, e.g. from SoundCloud).

Perhaps it's a product code for something, and the blog post is supposed to highlight the quality aspects of that product. 3ccxyphyvyc3s9uupfu42gnzlvvvv11uk8 extra quality
Another possibility is that this is part of an SEO strategy, and the user wants to include specific keywords for search engine optimization. However, using an alphanumeric string as part of the SEO keywords is unconventional. It's more likely that they want to create content around a product with that specific ID, which could be part of a larger database or internal system. In summary, the user probably wants a blog
