Hey! I'm a beginner and made my first website 10 days ago. I noticed 7 of my pages are indexed and 2-3 pages are categories. When i'm looking at the excerpt of these categories on google, it's showing the excerpt of a post from that category. I have a feeling it's not really SEO-friendly isn't it (duplicate content?)? What can i do to resolve that problem please? I'm using SEO Yoast btw if it helps. Thanks.
