Hi Dennis! What do you mean by that website? That URL is from a price comparison website.
For metas: I am just recently added meta-description [Category-name. Product-description].
Categories: I am recently started to add nice descriptions to categories
Inernal linking: they were product tags ([product_name], [model_name], [manufacturer_name], [categories_names] ->with URL) on the product page, but I removed.
So linkbuilding is still necessary?
