Hey there. I have one multi-niche website which i'm struggling to rank over the past months. I'm working with low comp. keywords and pretty much of them are on second to 10th page of google serps. Now i decided to blast some PBN posts to increase their rankings. My site has 80 posts which i'm trying to rank, and i cannot afford PBN posts for all of them... So i come up with a strategy like this. To divide all my 80 posts into 10 categories with 8 posts each category. To no-index the categories pages to avoid duplicate content, and then to blast the category pages with some PBN posts. So in that way the link juice from the category pages will go into the posts which i'm trying to rank and possibly rank them. Is this possible and do i have some mistakes in the strategy? All thoughts are welcome.
