There's a few major parts to Ganking.
The first is understanding pathing. When you are trying to gank, you do not want to run directly at your enemy. This is especially true with Kindred. You want to move to cut them off. So say you are ganking from the river. You don't want to run straight at your enemy. Unless your positioning is really close to them. You want to come from as far back behind them as possible before you start running at them. This gives them three options. Run straight at you to their tower, run through the river and take the route into their jungle. Or to try and fight it.
Kindred is incredibly hard to gank with because she has a poor gap closer. Her early game attack speed is meh. But her early damage is decent. You don't want to blow mounting dread on stopping them from escaping unless their HP is low. Because it can be very important at guranteeing the kill.
The second thing to understand, is if your laner has a form of CC. This is REALLY important for ganking someone who's not low on HP as it can help gurantee a kill.
Third, you can not control what your players do. If you ping the hell out of their lane as you are coming in for a gank. And they do not assist you in ganking a lane. Don't bother ganking their lane again unless you don't mind taxing. A jungler's time is important. Revealing yourself at any moment gives the enemy jungler the go ahead to simply go into your jungle, steal your farm and gain a level difference of 3 on you. At that point, good f*cking luck staying in the game.
Kindred is a little safer however. The people who know about kindred's marks will actively try to deny them to you. And will usually destroy their route to go quickly take care of the camp. Or they waste time trying to ambush you. Most Kindreds will normally just ignore the camps because the risk vs reward they present is just incredibly unfair (Yay for enemy junglers knowing your goals).
Fourth is routing. There are multiple routes for you to take when you want to gank someone's lane. And certain lanes are easier to gank if you are red or blue side. If starting blue side, top is often easier to gank because you can safely sneak into the lane from behind the enemy, just in front of their turret's range. The inverse is true for bot side. For mid, ganking from the bush unless you have additional help. The bushes are often warded. It is best to gank the mid laner from behind. But for many cases... this is just a bad idea in general. Unless your Midlane is fast to take advantage of the one man advantage, the midlaners are always a few levels ABOVE you. Meaning that you can be easily deleted if you are not assisted.
