You know that quiet nagging feeling when commissions don't match your traffic? I lived with that for six months before I finally cracked.
I run a home improvement site with decent traffic and click-through rates. But something always felt off when I looked at the numbers. So one weekend I clicked through every single link manually. What I found made my stomach drop. Three links had broken redirects sending people to a generic homepage instead of the specific product. Two more pointed to out-of-stock items with no affiliate parameter passing. And one somehow picked up a competitor's affiliate tag entirely. I'd been sending commissions to someone else for half a year. That's revenue I'll never get back.
Now I run a full link audit every month without fail. It takes about two hours and has already caught two more issues since I started. The boring maintenance stuff? Not optional. It only feels optional because nothing breaks loudly enough for you to notice.
Keep auditing, keep checking. Your future self will thank you.
