VBA turning sections of a recorded macro into something more efficcient - vba

Question

I am trying to optimise some data sorting code, the original code looks like it has been "written" through the use of excels "Record Macro" function.
The following is an example from the code.
Range("A12").Offset(z, 0).Select
Selec.Resize(Selection.Rows.Count, Selection.Columns.Count + (X2 - 1)).Select
Selection.Copy
Range("C4").Offset(y, 0).Select
ActiveSheet.Paste
In order to make this code more efficient, should i re-write this section to involve a range variable that its' .Value is equal to the Selection data?
The X2, z and y variables are used as part of the copy function and are slowly increased to make reading the end product much easier. They are altered elsewhere in the module.
I would just like to see some suggestions for what you think I should do.
I have read the very popular "How to avoid using Select in Excel VBA Macros" question on here, and am just looking for some further advice.

Answer 1

I guess this would be the easiest way.
Range("C4").Offset(y, 0).Resize(1, x2) = Range("A12").Offset(z, 0).Resize(1, x2)
Although I would advise:
to avoid .Offset and work with named ranges instead
to avoid .Copy and .Paste sometimes your data might be too big for your clipboard and using just the =-operator is way faster
to not name your variables with capital letters or additional ciphers, it can be very confusing
use this format .Cells( row, column ) instead of `.Cells("A1"). It's easier to handle and can be changed more easily via calculations

Copy/pasting isn't very efficient. Doing Range("X1").value = Range("Y1").value is better. This is what I would do
'change this
Selection.Copy
Range("C4").Offset(y, 0).Select
ActiveSheet.Paste
'to this
Range("C4").Offset(y, 0).Value = Selection.Value 'selection value is the range that is being copied.
