Example of Keyword Analysis [Moz Question]

Hello there!
This is an example of a keyword for a niche I am researching on Moz:



The purpose of this is a quick evaluation of the data presented through a few questions that I have. So let us begin!!!

1. The volume range is quite low. Of course, some niches may still be profitable with low VR, but with this keyword in particular, the KD is 18 and KO is 56, with a Potential Score of 64. Obviously it will be near impossible to find PS of 80+, so is it fair to assume that a PS of 64 is a generally good indication of whether a keyword can be ranked?
   
2. The average PA of the top 10 results is 31, and the average DA is 43. Almost all of the new posts I see advise that metrics are NOT the main thing that should be focused on, however I feel as though DA is still quite important as it can help in providing a clearer picture of the # of Authority Sites in any search. One of the pages has a DA of 66, would that be considered high enough to be considered an Authority Site??? What is the general score that could define if a site is an Authority Site??
3. What is the difference between RDs to D, and RDs to Page? Clearly the RDs to Page is very low compared to RDs to D.
4. With the VR or 1700, PS of 64 and average DA of 43, I conclude that it is quite possible with time and effort to rank a $$ site onto the first page of the SERPs. What do you guys think?
5. Lastly, this is only through Moz. Is it generally necessary to use more than one keyword analysis tool for more concrete results, or is using one tool just fine? Furthermore, what do you guys personally use? ATM I am using Moz and Semrush and I find them to work just fine.

And thank you to everyone posting such juicy information on BHW, honestly I am starting to see the bigger picture when it comes to SEO and I would like to thank everyone so far, even though I am still quite new and learning ever so much every day !!

What are you talking about ?

can't comment about 1 and 2, as they are personal beliefs.

3 - root domain to page is google.com linking to gmail.com/your-account. domain to domain is google.com to gmail.com

4 - please note that keyword searches is for month which means daily 60 visits out of which first position will get only 30 visits. Now you calculate how much you can make

5 - I personally check sites on google search to see how strong they are. If weak then go ahead.

Looks possible to rank , but search volume is a bit little.and 1/3 of search is what normally top 1 get

Not too sure about moz, I typically use long tail pro for checking keyword difficulty before manually check the sites.

Most software will be somewhat accurate but they can never be 100% accurate . You still need to manually check to confirm. And all this software just provide you value to let u know when compared to other keyword , it is a bit easier to rank.

There are lots of things that might affect it. Brand name , ecommerce lean etc. e.g product name , from keyword revealer will return low or no competition by their definition, which a lot of seller provides and lots of newbie fall into that trap . The truth is that high chance it is ecommerce lean, Google is bias towards ecommerce website , and it is a lot harder to rank than it actually shows
