H1 Tag and Meta Keywords is missing

[Furqan]

Hi,
This is my 1st post on this forum and I need help. I saw in Mozbar that H1 Tag and Meta keywords are not present in my site.
I am using Porto theme and I'm not the technical person so guys any suggestion for me? 
Here is my site: https://www.lcd4laptop.co.uk

Thanks in advance.

Regards,
