Hello members, I have the WordPress website with theme KARMA in it. The problem I have is that after running the XENU I found that I have the following URLS: www(dot)domain(dot)com/?p=1530 www(dot)domain(dot)com/?p=1533 www(dot)domain(dot)com/?p=1555 and more.... When I click on it, it goes to my human readable URLs, so it is duplication as for me. So I don't know : 1. How they appeared? 2. Is there SEO impact by having them? 3. How can I delete them OR exclude them, so Search engines wouldn't see them ,because it is duplication. My second question is about the TAGs . When we create a tag in WordPress it does create the page for it such as www(dot)domain(dot)com/tag/how-to-do/ . If I created the tag "how-to-do" & tag "do-it-yourself" and then used it on the same blog post it will appears on both tag's pages www(dot)domain(dot)com/tag/how-to-do/ www(dot)domain(dot)com/tag/do-it-yourself/ so this way I have the duplication, because both tags URLs shows me the same post. Question: 1. Should I keep TAGs? SEO sowtware shows it as an critical error as the duplication. 2. If I'll delete the TAGs, sho I redirect them for SEO juice ? Thank you a lot.
