Ask about web design

Hello,

I’m web developer, SEO and ads. But I’m a “chicken” web designer.

I just designed a sales website. But I don’t know if this is okay or not. Can you help me check it out? This is URL of website: https://chieusangphilips.vn/.

Thank you so much,

Ah, Can you help me check categorys product page important and product page?
