Welcome to the Q&A Forum

Hi There, I do agree with Martijn that this does not appear to be keyword stuffing of the content, I do not think this would cause any issues. However, I did notice that the meta keywords tag is extremely over-optimized, this could be considered keyword stuffing/spamming. The meta keywords tag does not provide any value, major search engines abandoned it as a ranking factor years ago. However, it is possible this is sending spam signals. Google states that they ignore the meta keywords tag, but Bing has acknowledged that they review this tag as a spam signal. I noticed that many pages contain meta keyword tags that are fairly 'stuffed', I would recommend removing these or significantly decreasing the keyword usage in these tags. Example: Screaming Frog Screenshot

I completely agree with Clayton's response so I won't touch on that. To answer your other question though of whether or not Google will see the second site as being duplicate, the short answer is that "it shouldn't". Google will only reference the last-crawled copy of your website so the only time there could be potential for being seen as duplicate is if the new domain gets crawled before the old one is recrawled. Even then, I wouldn't expect it would have a measurable difference on the progress of a new domain. Don't forget, you can't get penalized for duplicate content. The worst that can happen is your rankings slide somewhat but being a new domain, it'd take a few weeks/months to see any real rankings anyway so it's mostly a moot point

Sorry, don't have anything public around this that I'll be able to share.

Hi, I think adding Top 10 to your title tag will definitely help with your CTR since many users are looking for lists such as this.  You might get a temporary uplift in rankings, but if the user comes to your site and then doesn't find the word "Top 10" near the top of the page and just sees a list of 25 hotels, they will most likely get confused and just leave your site without staying for very long.  Especially if you just have a random list of hotels with no regards to rankings at all.   Thus your rankings might suffer since Google tracks dwell time on a page and user's intent.  So, if the user just leaves your site right away then that temporary uplift in your ranking might be lost. Hope this helps.  Let me know if you have any other questions.
