Welcome to the Q&A Forum

Hi Andi! I'm not so sure the division of DA across pages on a domain is that cut-and-dry. It's not some finite material that can only be divided among so many pages, and a page's Page Authority can differ from its domain's Domain authority radically. Remember, also, that Domain Authority is a proprietary Moz metric measuring, primarily, a domain's overall link strength. It _approximates _Google's ranking algorithm, but it doesn't nail it exactly. In addition, the lack of backlinks to that page in Open Site Explorer doesn't mean that page has no backlinks. For a dynamically-generated page like that it's much more likely that OSE simply hasn't seen it. Remember, OSE doesn't necessarily crawl every page on a site, and that's especially true for particularly deep pages. Frankly, I would expect that the page on the larger site with DA 94 would do better than a page on a smaller site with DA 50. The DA 94 implies a much stronger site.
