keywords on URL + categories on ecommerce site

[juanmig...@gmail.com]

Hi all,

I'm building an e-commerce site with OpenCart, which is sorted from general categories to specific ones. There are 10 main categories, and each one is parted according to the sublevels needed for an easy navigation and ordered classification of the whole catalog, about 1600 unique SKU or references.

As a result, when you arrive to the final product , the URL (pretty SEO friendly rewrited by .htaccess & apache) contains more than one occurrence of the keyword for this product or group of products, and has many levels, from 2 to 5, like this one (I'm also using dashes) :

mydomain.tld/catalog/[kw]-category-1/[kw]-subcategory-2/subcategory-3/[kw]-product-with-some-specific-feature

The keywords usually is repeated on breadcrumbs, left side menu, page title, H tags, description and product name, and meta description and keywords. Not so much as a matter of SEO, but because is the info I have for the product, and the most relevant I can provide for people to find the product.

I know i should keep the numbers of sublevels short, but the site is built for the users to descend comfortabily until they found what they need. The farest products is 4 clics away from shop home page (catalog subdir), plus 1 one from website home page. 

How bad is this? Could these URLs be considered as spammy? Too many sublevels? Sometimes I'm almost forced to repeat the kw (say, the brand before or being part of the name), or some products (like ink colors) will have repeated SEO URL keywords.

Thanks in advance,

Miguel
