Your LinkedIn strategy depends on your goal. Some goals:
– Create a personal brand
– Impressions & more connections
– Sales
If you want to work on your brand, for example, you need to focus more on personal content.
If you want to grow a big network or get lots of impressions, free giveaways and training files works well.
For sales focus on the pain points of your client and try to add a specific network.
Now it’s still important to have a mix of all these content types.
So, yes you can do these things all together but if you want to focus on one goal it’s better to lean towards a strategy that fits that goal.
