...
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 53% of the final above-the-fold content could be rendered with the full HTML response .
Minify HTML
Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 1.1KiB (14% reduction).
Minifying https://www.zeiss.co.uk/corporate/home.html could save 998B (13% reduction) after compression.
