I am building a blog type website with articles. In one category, new articles will be posted every 2-3 days. I need the last article from that category to be (totally) displayed on the front page with sharing options comments.
Once a new article is posted, the old one gets a specific URL and is put in his category.
I was wondering the impact it has on SEO to change that article periodically on the front page. As shares made on the featured article will share my home page, will the old articles still benefit from their rank once the URL has changed?
