Hey there,
Just had this question for a while now. I have a marketplace that due to the users being able to add a description to their items (images, videos, content in general) those item pages have been getting quite heavy. I have optimized categories and search pages to load amazingly fast but the item pages are unbelievable heavy (some of them).
Do you think Google ranks a site as a whole for the speed or on a page by page scenario? For example, let's say I have a page about broccoli and a page about carrots. The broccoli page is tremendously fast and the carrots is being amazingly slow.
Does the carrot affect the broccoli? :P
Kind Regards
