gear level/ilevel and content/recipe level need to be around the same. the higher the difference, the slower the spirit binding.
If you wear (as an example) lv57 crafting gear, then lv 57 recipes are good to spiritbind (or lv 57 enemies if you wear them on a battle job).
test out different recipe levels or enemy levels or content minimum ilevels to find the best options for your gear.
Maybe tell us what gear you tried to spiritbind how or where
Does the spiritbinding boost in Diaden effect crafting and gathering?
