1. Is it comfortable for you. thats the most important one.

2.The action of the guitar(the distance between the strings and the fretboard) should be at fair and playable distance.

3.Inotation (tuning). Check If it it stays in tune. play it for a while and keep notes.

Avoid Buying online guitars, it is very risky, sometimes you can get a good product but it is more safe just to go down at the store and play and see it for yourself. It will give you more idea about the instrument you are going to buy. Only some expensive guitars can be trusted buying online but only sometimes.

It is safe, but i would suggest you to go to your nearest guitar store or any store because it needs to felt in the hands of the player and then only you can make a decision on buying it because the neck of the guitar, the body of the guitar makes a lot of diffrence.

Maybe you need a thinner neck and a large body, thats where online shopping laggs, pictures are very deceptive and can fool you sometimes and you will be disappointed. 

 In Online Shopping you might get just one piece of the same guitar, but in the store you will get the same guitar with different pieces beacuse not every guitar is same even if its the same model.

hope it helps!
