Need help with lilac

My well established lilac bush has produced this year loads of flowers over half the bush and the other half is bare! Last year it was covered all over in blooms. I did prune it last year as soon as the blooms died. Any ideas please?

I can't think why unless you cut it back harder in some parts perhaps?
I know I did a bit of a harder cut on ours a couple of years ago and think it did not flower as profusely. It grows a bit wonky towards the sun so I re shaped a bit, cutting into older wood.
Is the foliage healthy, just no flowers?
If not then check the stems and bark too in case it has had some damage or disease.
If the above is not applicable a photo or two close up of stems and leaves might give some eagle eyed member a clue.
You can prune out old wood, and take out thin straggly stems too, and that will also benefit it. It helps to create a good open structure and increase air flow too. Like many shrubs, these things help them stay productive long term
I live in west central Scotland - not where that photo is...
