In our main website with a branded domain, we have a webpage about a specific campaign. We also have an indexed landing page/microsite with recently optimized content and its own domain (domain contains the keywords).
I want to update/optimize as well the webpage of the branded website. I am thinking of targeting the same high-search volume, long-tail keywords I used in the landing page/microsite as H2s (because there are no other keywords to target).
From our business’ standpoint, what problem/s can you foresee if the same long-tail keywords are used by both of our sites with different domains? Obviously, I have to make the content different to avoid duplicate content, but I plan to keep the H2s. Thanks!
