For me personally improving my soloing skills was and still is hard. It takes a lot of practice. But one thing helped me instantly and a lot!
Here we go!
Learn where on the fretboard the different notes are.
For example search all the A‘s then all the e‘s etc. Start with the low e and a String. This will help you with playing scales. For example you have a Banking Track in a-Minor and you want to use the a-Minor scale. Because you know the fretboard you know where to start with the first position of the a minor scale.
Or lets say you are in the middle of an awesome solo in a-minor but you lost track where you are on the fretboard. Because you know all the a’s you can always come back to the root and continue shredding. Same for other keys. Hope this helps Enjoy playing and checkout my Backing Tracks
