I run this website: http://knowledgeweighsnothing.com/ It was initially built to get traffic from Facebook. The vast majority of the 1300+ posts are shorter curation style posts. Basically I would find excellent sources of information and then do a short post highlighting the information and then link to the original source (and then post to FB and hey presto 1000s of visitors going through my website). Traffic was so amazing from FB at the time, that 'really stupidly' these posts were written with no regard for search engine rankings. When Facebook reach etc dropped right off, I started writing full original content posts to gain more traffic from search engines. I am starting to get more and more traffic now from Google etc, but there's still lots to improve. I am concerned that the shortest/weakest posts on the website are holding things back to some degree. I am considering going through the website and deleting the very weakest older posts based on their quality/backlinks and PA. This will probably run into 100s of posts. Is it detrimental to delete so weak many posts from a website? Any and all advice on how to proceed would be greatly recieved.
