I was advised to ask my question here where I initially placed it on Stackoverflow.
I'd be grateful for some feedback on what to do to fix my page speed insights. A step by step perhaps and how. I'd prefer to optimise the sites myself and I'm not sure how to do this or where to start.
I've been advised that I should stay away from plugins to speed up wordpress websites.
We do not need CDN as all the websites are focussed on clients in our own country.
- Our ISP has a good server so server config isn't a problem that I am aware of.
- Wordpress Administration: I have several plugins to optimise images and compress css etc but apparently the wordpress core already does this?
- GZIP support apparently can be enabled via 1 line of code
update_option( 'gzipcompression', 1 )but where do I put this?
- Our wordpress theme is DIVI. Not the fastest. Perhaps I should change the theme on all sites?
Many thanks for your suggestions and advice in advance.
