How can a bookmarklet be ADDED on mobile Chrome without copying and pasting? On my Android phone, how can a user add a bookmarklet to my Chrome bookmarks, without needing to use another device, and without copying and pasting?
I have a bookmarklet on my website that I want other people to add to their bookmarks, so I'm looking for a straightforward method.

Bookmarklets are bookmarks, but of which contain Javascript code instead of a regular web link.

Bookmarklets can be added to Chrome on the PC very easily in many ways.  


However, on Android, if the bookmarklet is displayed as a link on a
page, it cannot be "dragged to the bookmark bar" as with a PC.   
If I try to open it in a new tab, the address bar will not contain the
Javascript, so the user can't use the bookmark button.
Tapping the link to the bookmarklet will not put the code in the address bar either.
The only way I've been able to add a bookmarklet on my
phone has been to tap and hold on the link, then tap "Copy link
address", then edit a pre-existing bookmark's link and pasting in
the bookmarklet code, then renaming said bookmark. But that's a pain, and trying to explain it to non tech savy folks isn't happening.


Is there a more simple method?  

Note that I have a particular bookmarklet that even when added on my PC, does NOT sync to my Phone's bookmarks. I believe it may be due to the length (It's over 9000 characters!). This is why I need an easy method for users to save this bookmarklet.
You can add (and execute) bookmarklets entirely in Android Chrome.

The caveat: it takes more work than just drag-and-drop in the desktop counterpart.

Save a bookmarklet (Android Chrome)


Long tap the desired bookmarklet
Select Copy link address
Go to Menu (three dots) and tap the Star (bookmark)
BEFORE IT DISAPPEARS, tap EDIT! (at the bottom)
Erase everything in the URL field, and type javascript:


Side note: If the url of the page is really, really long, you might want to long tap the url contents: the keyboard will appear, and then start typing immediately.

Long tap at the right of the javascript: and then tap PASTE
If you did it right, the begginning of URL should look somewhat like:


  javascript:(function(){lots-of-code-here...
  
  (The : is still in javascript:)

Change the Name to something useful (you'll use it later, see below)
Optional: Pick the destination Folder where you want your bookmarklet stored.
When done, press the back button.
You might want to test the bookmarklet. Read below:


Execute a bookmarklet (Android Chrome)

From How-To Geek (the link you sent):


  In mobile Chrome, you’ll need to launch the bookmarklet from the location [address] bar. Open the web page you want to run the bookmarklet on, tap your location bar, and start searching for the name of the bookmarklet. Tap the bookmarklet’s name to run it on the current page.
