Hi guys, an older article of mine is ranking #7 quite stable for a longer time now. Since the content is not that fresh anymore and I see room for serp improvement I wrote a completely new fundamental article for this search term and optimized it well on- and offpage-wise. Unfortunately the new article is not ranking at all. I even linked from the old ranking article to the new one and took every article, which is related to the term and linked it to the new article. No serp movement at all. Now I don't know what to do anymore? I thought about 301 redirecting the old article to the new one, or including the exakt content of the old into the new one and then deleting the old one. Any hints?
