TIFF stands for Tagged Image File Format.
Add a GeoTIFF
Adding a GeoTIFF to GeoServer is very easy.
1) Simply navigate to the Config->Data->CoverageStores->New menu:
2) Select the Tagged Image File Format with Geographic Information dataset option.
3) Enter the name you want to use for the dataset in the Coverage Dataset ID field. Then hit New.
4) You will be taken to the CoverageStore edit screen where you will have to enter the path to your GeoTIFF file. You can enter a relative path to your data directory if that is where the file lives, or you can enter an absolute path to the location of the file.
For example: C:\my_data\rasters\canada.tiff
5) Hit the Submit button and save.
6) Next head over to the Config->Data->Coverages->New menu:
Select your coverage store and hit the New button.
7) You will now be in the Coverage Edit page. It will know your projection, so all you have to do it hit the Submit button at the bottom, then apply and save the changes.
You should now have your GeoTIFF registered in GeoServer.
