Welcome to the Q&A Forum

Hello, I have an ecommerce site with all pages crawled and indexed by Google. But I have some pages with multiple urls like : www.sitename.com/product-name.html and www.sitename.com/category/product-name.html There is a canonical on all these pages linking to the simplest url (so Google index only one page). So the multiple pages are not indexed, but Google still comes crawling them. My question is : Did I have any interest in avoiding Google to crawl these pages or not ? My point is that Google crawl around 1500 pages a day on my site, but there are only 800 real pages and they are all indexed on Google. There is no particular issue, so is it interesting to make it change ? Thanks
