Hello everybody, I'm making some updates to one of my websites, and I'll soon have new articles with fresh content. For example, I have an old "Best xxx products 2014" and now I just want a "Best xxx products" page what I'll update on a monthly basis. I plan to 301 redirect the old article to the new one, as they're still ranking quite well. Question is, should I delete this old page/article after the 301 ? Even if visitors will always land on the new page with the 301, I don't want to have both pages displayed on my article list on my WP Category. Any idea of what is the best way to handle this ? Pros and cons ?
