Sorry I am just getting to answering this question now. The main causing of skips is improper setup. The best thing you can do is get a small digital scale to double check that you are setting your VTF correctly.

Re: Antiskate I recommend you search for Peter Lederman's videos (they are on Youtube) on the topic and set anti-skate that way.
The trouble with some of these budget turntables is that the anti-skate dial on them is not very accurate. You need to ignore the numbers and watch the behavior of the arm. If the arm is pulling too much away from the lead-in groove it probably means the tension on the spring underneath the dial is too tight. A proper setting with a too tight spring will involve a lower AS setting than VTF.
Also, the turntable needs to be placed on a level surface, on a sturdy table or rack of some sort. Get a good quality torpedo level and check the plinth and platter to make sure they are level (check in multiple places). If you need to adjust one or more of the feet, putting business cards or playing cards under the feet will help you level the turntable properly.
Speakers, subwoofers, etc. should be moved as far away from the turntable as possible and not sitting on the same surface.
After all this, if you are still getting skipping you can try a heavier tracking DJ/broadcast type cartridge with a conical stylus.
If you are playing a lot of old, heavily worn vinyl with scratches be aware that some of those will have skips in them caused by damage. A record that is damaged like that can sometimes be "fixed" by surgery using a wooden toothpick and a magnifying glass, or repetitive backcueing using a conical DJ grade cart ONLY.
Before you do "surgery" or anything else, make sure the record is clean. The cheapest real cleaning system for records that I can recommend is the Spin Clean.
