I have my suet cages hanging off of a tree at the back of my yard. I took a length of heavy gauge wire, wrapped it around the trunk of the tree about 4 feet off the ground, then I hung the suet cages from the wire using the metal clips that came with the cage. I found out that if I didn't use the wire the squirrels would chew through whatever was holding the cages up.
I get starlings stopping by all the time for lunch and dinner :)
Sometimes, after the suet is gone and I rebait, it takes the birds a day or two to discover there's more food there. You could also put out a "high visibility" bait on the ground just to get them to come into the area and discover the suet. One time I took a box of ritz crackers that had gone stale and I broke em up and tossed em on the lawn for the birds. Well, I got birds alright, but I was amazed that it was almost all starlings,,, guess they like ritz crackers.
