Hi @webdew , Thank you for your answer!
- We already tried to minify the JS and CSS files but that didn’t have any impact. Also because the JS used are linked to the HubSpot elements and we can’t reduce them.
- Yes, the lazy load is a great option that we use
- We use a google font, which we were advised to store locally instead of using the API, but we couldn’t implement this
- For videos, thanks for the tip
- For the JS thanks for the tip 
Do you, by any chance, have any tips specifically for mobile? Because our speed is good on Desktop, but it is the mobile version that is a bit low.
Best,
Laure
