Chain link fences that are set in soil need to be solid. That is, soil can shift as tree roots move around and grow. This can compromise the post strength. So, the cornerstone of any strong fence lies in the post. This article explains the best techniques for installing solid and reliable posts directly into soil.
Dig a Deep Hole or Use Concrete Footing
A post set directly in soil should probably be about half as deep as the post height. So, for a 5' tall fence, you will need a 2.5' deep hole. This is obviously not a set rule, and it partly depends on the consistency of your soil. On some soil that is extremely hard, it might be nearly impossible to dig deep enough. If this is the case, you can reinforce your post by setting it in a concrete footing. Basically, you can dig a hole that is just a little wider than the post, and pour concrete around it.
In fact, this process works best if you actually pour the concrete mixture and water into the hole at the same time, before they are mixed together. Then, use a stick or mixing device to create the concrete around the post. Obviously, before you do this you will need to make sure that you are ready to set your post into the concrete. After only a few minutes the concrete will start to dry and coalesce with the soil. This can be stronger because it causes the concrete to bond with both the soil and the post.
A concrete footing will strengthen your post, but you still want to try and dig your hole as deep as possible. For instance, if you need a 3' deep hole, but are only able to dig 1 foot deep, adding concrete footing isn't going to make your post strong enough. But, if you're able to dig 2' down, the concrete footing might help.
Of course, if your posts are closer together so that they aren't supporting as much weight from the heavy fencing slats, they might not need to be so deep. Regardless of the type of fence you are installing, you always do your best to ensure that your post are strong and level as possible. All in all, the time and effort you spent creating strong and reliable post will probably far outweigh the time you spend installing the rest of the fence.
