If you drag your mount out to the same place every time then when you get a good alignment mark the spots for each leg. I put paint spots on the driveway and made a simple levelling base for the slight slope.
I also did a solar noon Nth/Sth line to start with and a big T square gave me East/West.
If you are using a DSLR camera on the scope you can also do the stop start Drift check.
Get your Dec right first with an Inclinometer app on your phone or tablet, something with a nice straight edge.
Start a longish exposure 30-60 secs with camera pointed towards abright star near zenith, Stop tracking for about half the exposure time then fast forward the mount to capture an offset trail.
The exposure should give you a V shaped pair of trails showing the difference start adjustiing to eliminate the V.
There are software supported (PHD2 eg) which can do all this for you as well. You can minimise this with a consistent setup but one day you'll decide it's time to build an Ob ! There is no turning back ....
