How hide bread crumb without damage to seo ?

[seog]

Hello

 

Due to design purposes, I want hide breadcrumb but I read in the past that it is bad for google rich snippets and SEO

 

I look to find the least negative solution possible for SEO purposes in product page and I think in different options such as:

 

1.CSS options (The professional SEO say that display:none is very bad for SEO)

---------------------

.breadcrumb {

display:none}

 

.breadcrumb {

background:white}

 

.breadcrumb {

background-img: url (../img/img-for-hide-breadcrumb.png;

position:absolute}

 

 

2.File options (If I comment varible then the page dont read breadrumb)

--------------------

comment {*include file="$tpl_dir./breadcrumb.tpl"*}

 

 

NOTE: I see that if I delete {include file="$tpl_dir./breadcrumb.tpl"} from header.tpl and I paste at bottom of product page then there are subcategories that are not displayed. Example:

With breadcrumb in header are all the cats & subcats in product page: Home > Mainly Cat > Subcats > Product name

With breadcrumb pasted in product page and deleted in header I see only: Home > Mainly Category > Product name

 

Any suggestion about what is the better options?

 

best regards
