The list is not the strategy
The download is a set of bookmarking destinations. Dumping every URL into all of them is how people conclude "bookmarking is dead." Treat the list as a menu. Pick the sites your reader still uses.
Write a title a human would save
Bookmark traffic still comes from curiosity. "Ultimate guide to success" gets ignored. "Why my posts get traffic and zero emails" gets a click. Use the same title on the page so the visitor does not feel baited.
Submit after the page is ready
A bookmark to a homepage with no next step wastes the click. Point to a spoke or the quiz. One link. Then wait. Repeat only for new or substantially updated pages.
Keep a tiny log
Site, URL submitted, date, clicks if you can see them. After ten submissions you will know which two destinations deserve a monthly slot. That is the whole system.
