My first tip would be to make sure you cover some ground. If the fish aren’t there you are not going to catch them. Perch, in general, like to shoal up. If you find the shoals, you’re in with a chance of catching some Fish.
Be prepared to walk around a bit and don’t get lazy and wait for them to come to you. Perch love snags and structures, Always look out for fallen branches, overhanging bushes, concrete structures reed beds etc.
They will quite often be hiding away tight in the undergrowth. So when casting it is worth getting the lure right up to the snag/structure, in order to entice the Fish out.
