I am struggling with our product pages not being indexed. On GSC, it shows that the URLs in question are "Discovered - currently not indexed".
The content on all of our product pages is not duplicated from other pages and is 100% unique. For the product description, there are about 2000 characters.
The URL structure is pretty long, for example: sitename.com/product/this-is-a-product-test-of-the-long-url-structure-does-this-help-300
According to GSC, there's 257 pages that fall under the "Discovered - currently not indexed". Some of these pages have been created a while ago and still haven't been crawled by Google.
There's no Google-selected catatonic, its unique content.
Most images used on the product pages are not of our own, but instead taken from the manufacturer website.
A lot of these pages share the same keyword, such as a brand name in the URL.
If someone could point me in the right direction, I would appreciate it! We're losing out on visibility if you can't find what you're searching for.
