I don't have an amazing LinkedIn either but one tip I can give you is to put your skills in the headline since that's what recruiters see on the search page.

So, instead of saying: Web Developer at Style Collective and Stingray Branding

It might say: NodeJS/React/Go Web Developer

Also, honestly, don't bother adding random people on LinkedIn to grow your network. It's not worth it. Stick to people you know whose careers you want to follow.
