Regarding Canonical Url

[areygie]

We have a e-commerce website. Our own homegrown:-)

We recently visited Google Webmaster tools and could see that Google mention we have double Meta tags for some main and subcategories.

Each Product Category on our site have a subcategory/ Sub url -  "Bestseller", "On Sale", "just arrived".  The sub url is not a really a real category and we can therefore not make totally unique description and title for does urls.

domain.com/category

domain.com/category/bestseller
domain.com/category/on-sale
domain.com/category/just-arrived

We are thinking about 2 solutions.

1. Canonical Url on subcategory pointing to main category.
2. Or add a word bestseller, on sale or just arrived in front of the meta title/description. We can do this from code.

I personally opt for option 1. But I am little unsure what is the best way to go.

Thanks in advance for your advice

i say write a unique description and title, dont be lazy. Make sure page has unique and usefull

if you use a canonical tag you will remove the pages from the index. only the canonical will be included.

If you are going to have a subcategory page (or any page for that matter), that page should be unique and usefull in its own right, or simply merge the content.

See the problem is that its not really a subcategory, its a filter that displays filtered products from the given parent "category".

all categories in our system have this filters. There is no place we can edit the data. As its not really a real category. If that has been the case we would of course have made UNIQUE descriptions.
