1a) Google valuate the site at URL level not domain, so Ahrefs DR (same as Moz DA) only confusing people about any keyword for any given url.
As the results, Ahrefs users aren't able to evaluate their chance to any given keyword.
Additionaly they don't know the "topic" and "trust" which use Google.
1b) If link not increasing the search visibility, usually is worth nothing, because I am not the collector of useless backlinks.
Also I don't like wasting the time and money for low effective "strategy" with such links.
1c) I told you that "updated DR calculation" is useless same as was before, so no matter that it was even updated.
If you not using TF and TTF but useless DR your effectivity is pretty low for the all reasons above and I am not writing about You, but your methods.
2a) No matter how you using Ahrefs, it don't have TF and TTF which Google use.
As I wrote earlier, Ahrefs it's product for beginners, because for $100 you have some KW and some BL data plus pretty nice UI.
2b) Lets think what you are able to achieve by "manual check"
- you aren't able to valuate PR
- you aren't able to valuate TF
- you aren't able to valuate TTF
Only you're able to say if site look good or not.
But Google algorithm don't care about how site look, it care how much any site is useful for users.
Happy users share the links which increasing PageRank, which confirming this value, same as traffic.
So, in summary such "review" is not worth too much, just wasted time which costs money.
2c) You're wrong. Please check NEW PageRank patent and compare it to how Majestic creating TF.
Of course it never will be exactly same, but it's more than enough good in most cases.
Cheers, Greg.
