A client of mine has a supplements shop and there are now many similar pages around a product. domain.nl/product.html domain.nl/product-2kg.html domain.nl/product-4-5kg.html For 6 months there are rel = canonical on the 2kg, 4-5kg pages, but Google still puts the wrong urls higher than the right. With a new update, we all grouped into one unique url domain.nl/product.html What should we do with URLs that will no longer apply? Should we put a 301 on that pages? Who has good advice.
