I added 4 articles on a website a month ago. Two of them were main topics and the other two were sub-topics, more like a topic cluster. There are other products as well on the website that I have internally linked to the 2 main articles. I got around 30 referral links to the main pages, and the domain authority pretty much increased in a month. However, the keywords I targeted on the 2 main blogs didn’t work at all. They only received backlinks, but the organic keywords are still at 0 even though the KD was hardly 5 with a pretty high search volume. Is it a matter of time, or do I need to find another technique?
