We have 2 e-shops, one B2B and one B2C. Both of them are under the same domain. Both shops have similar products, therefore a lot of times different pages have the same title tag (since the title tag gets the value from the product name).
In this question: checking for duplicate title and meta description tags across multiple subdomains I read that
if the content is unique on each page then it doesn't matter if titles are duplicate. Titles are duplicated in the thousands daily due to the fact the title tag is only so many characters and duplicates regularly occur naturally, this isn't a factor.
but in our case, the content is not actually unique since we have the same products.
Do you think that is possible that issue to affect the e-shop's ranking?
