Old product URLs still indexed and maybe causing problems?

[mcampanaro]

Hi all, Need some expertise here:

We recently (3 months ago) launched a newly updated site with the same domain. We also added an SSL and dropped the www (with proper redirects). We went from http://www.mysite.com to https://mysite.com.

I joined the company about a week after launch of the new site.

All pages I want indexed are indexed, on the sitemap and submitted (submitted in July but processes regularly). When I check site:mysite.com everything is there, but so are pages from the old site that are not on the sitemap. These do have 301 redirects.

I am finding our non-product pages are ranking with no problem (including category pages) but our product pages are not, unless I type in the title almost exactly. We 301 redirected all old urls to new comparable product, or if the product is not available anymore to the home page.

For better or worse, as it turns out and prior to my arrival, in building the new site the team copied much of the content (descriptions, reviews, etc) from the old site to create the new product pages.

After some frustration and research I am finding the old pages are still indexed and possibly causing a duplicate content issue. Now, I gather there is supposedly no "penalty", per se, for duplicate content but a page or site will simply not show in the SERPs. Understandable and this seems to be the case. We also sell a lot of product wholesale and it turns out many dealers are using the same descriptions we have (and have had) on our site. Some are much larger than us so I'd expect to be pushed down a bit but we don't even show in the top 10 pages...for our own product.

How long will it take for Google to drop the old and rank the new as unique? I have re-written some pages but much is technical specifications and tough to paraphrase or re-write. I know I could do this in Search Console but I don't have access to the old site any longer. Should I remove the 301s a few at a time and see if the old get dropped faster? Maybe just re-write ALL the content? Wait?

As a site note, I'm also on a Drupal CMS with a Shopify ecommerce module so maybe the shop.mysite.com vs mysite.com is throwing it off with the products(?) - (again the Drupal non-product AND category pages rank fine).

Thoughts on this would be much appreciated.

Thx so much!

Ok, thanks James. I'll stick it out with the 301s on these. I appreciate your input.

Thanks James. All the pages are set up with 301s so no 404s are returned for these. I'm thinking that is why google is not de-listing them. I don't know if having both of these urls indexed with very similar content, much identical, is causing google see it as duplicate and not return either in SERPs.

If I remove the 301 and allow the 404 response will google drop the old page faster? Then hopefully the new pages will begin to rank.

Thx!
