For a sample of data it is a measure of the spread of the observations about their mean value.
Standard error is random error, represented by a standard deviation. Sampling error is systematic error, represented by a bias in the mean.
It would help to know the standard error of the difference between what elements.
The standard error increases.
the purpose and function of standard error of mean
The standard error of the underlying distribution, the method of selecting the sample from which the mean is derived, the size of the sample.

Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
Standard error of the sample mean is calculated dividing the the sample estimate of population standard deviation ("sample standard deviation") by the square root of sample size.
