Hi there,
the two major issues i see is:
1. Advert scripts.
You should look at deferring their loading. Many optimization plugins do that – or you can use the Flying Scripts plugin.
2. Google Fonts
These will tank your site and Google won’t warn you of that.
You can try installing them locally to improve their load times:

I would focus on those first as they will make the biggest improvements.
