my posts are usually (*product name review*), if a certain keyword is competitive, I assume I have to create multiple high-quality content around that same keyword. My question here is, should it have it's own category? or they all can be in the same category as everything else?
OptiMen review, this is a multivitamin brand, should this and all the related posts which I will create about this brand be in the category where I have reviewed all the other multivitamin brands or they should have their own category and call it for example, 'Optimen category'?
And what's the proper way to internally link them, if let's say I have created about 4 posts just for that particular keyword/brand/product or whatever? should it be like page 1 links to page 2 and 2 links to 3?
What's the proper way to link them? Thank you in advance.
