Seo and div display:none


Staff member
I'm just wondering if display:none is affecting my sites seo as I have for certain keywords dropped rank in google over the past few days since implementing this into a new homepage re-design.

I am using wordpress and displaying random post images on the homepage, getting the excerpt and hiding it using display:none and when a user hovers the image it displays the excerpt as a tooltip.

I have read a few conflicting articles on this and watched Matt Cutts youtube video but that doesnt really give me an answer for the way I have implemented it.

So I am hoping someone on here can give me a bit more insight as to whether it is not good seo practice or doesn't make much difference?
