      Hi,

      If we merge two sites say, one with DA 35 and another 20 what will be resulting DA of the merged site?

      Secondly, will the result vary based on which Domain is kept and which one is 301ed?

      ps :- all content is transferred from one to another using 301.

      Regards,

        Thanks Vijay!

        Also something to note though is that for us to update any 301 link, we would need to re-discover the old pages to be able to follow and update the metrics. This is not likely common for sites with lower authority since old links are not continuously shared on new pages/articles/blogs.

        Link Explorer works solely through link discovery and crawling. For every link we index/crawl, these links are not guaranteed to be re-crawled.

        Eli

          Hi There,

          It is a tricky situation, in this case using 301 would not directly transfer the domain authority but since the traffic might get transferred and eventually the site would trust and get some increase in domain authority. Given the above situation, it would be advisable to keep the higher authority domain and work on it, let the lower authority domain be 301ed to higher DA.

          I hope this helps.

          Regards,

          VIjay

            Unsolved REfund

            refund

            Hello,
            We have no idea what Moz is or how it is used. We only learned your name when our credit card was charged. We want to cancel this subscription transaction somehow and get our money back. We called our bank to cancel our card and stated that the transaction was made without our knowledge. Please refund our money.

            If your brand name (e.g., "Example Brand Name") is different from your brand's domain (e.g. "www.ebn.com"), does the Brand Authority tool measure authority for "Example Brand Name" or "EBN"? Thanks!

            0% visbility and no ranking keywords.

            Yesterday, we uploaded a new campaign but it appears it has 0% of visibility and no keywords ranking. What might be the problem? The website has a domain authority of 39 and 500 visits in the last week. But according to the Moz campaign they don't even rank for the name.

            Site Crawl Status code 430

            Hello, In the site crawl report we have a few pages that are status 430 - but that's not a valid HTTP status code. What does this mean / refer to?
            https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_errors If I visit the URL from the report I get a 404 response code, is this a bug in the site crawl report? Thanks, Ian.
