So I am building my website up, so far so good, only 2 categories and about 40 articles. Each category is different and several of the articles in each category are reviews.My question is this...I have 500 words of unique content on each review, and then I have around 300+ words of the exact same content across each review (different category different similar content)The 300 words of similar content is things like..Product contains eggs.product contains milkproduct doesn't have supportproduct company isn't active on social media.product doesn't have email support.Things like this, depending on the product and depending on how deep I dive into the reviews they range from 300+ words.Is it okay to have these reviews with this point back to my category landing page? I mean they're ranking for separate products not the main keyword as my category landing page.Should I rework my strategy and just take out that similar content?
