Hey! I totally get the frustration with ranking drops. Hidden links are sneaky little devils, aren't they? I've found that sometimes a fresh pair of eyes helps – asking a colleague or even a friend to take a look can reveal things you've overlooked. Screaming Frog is pretty good at crawling and identifying unusual link patterns, might be worth a try. On the topic of focus and problem-solving, I swear, a quick round of Sudoku in the morning really helps me sharpen my mind before tackling these puzzles. It's like a little brain workout! Good luck digging those links up!
