DA is not a ranking factor, yes. You can think about it as body weight - if I only tell you someone's bodyweight, you can only make an assumption. For example, somebody that weighs 95 kg might be well built and lean or somewhat overweight. Same goes for DA a high DA might be a result of "good" backlinks or a result of a spammy link building strategy.
This is a tricky question. While DA is not a metric created by Google but by Moz, it trys to estimate "PageRank" like scores as Google does. So it's not a ranking factor in itself, but what it's trying to estimate is. It's widely known that DA can be manipulated as can Pagerank and one reason Google stopped reporting it's scores. If DA is built naturally and with quality backlinks then it could correlate with better rankings.
Backlinks from High DA websites can improve your DA but does not mean it will help in higher ranking in Google. For good ranking your need first good on page and backlinks from real website by natural ways, if Google notice that you are purchasing links or inserting links forcefully then it can be reason of drop ranking.
DA is just one of many ranking factors that search engines consider when determining how to rank websites. Other important factors include relevance, content quality, site structure, and inbound links. Additionally, the importance of DA can vary depending on the niche or industry and the specific search engines being used. So, it can be said that DA can be helpful in predicting a website's potential to rank well, but it should not be the only consideration. A high DA does not guarantee high search engine rankings, and a low DA does not necessarily mean a website will not rank well. A holistic approach to SEO is recommended, taking into account multiple factors that can impact a website's visibility in search results.
DA is a MOZ's matrics to major the website's domain age on various factors. But it is not a ranking factor anymore. It is good to check while selling or buying old domains (other factors are also important). Most SEO thinks the links from the High DA PA websites are more powerful and have more value but it is not the case. There are many people who trick the DA and sell backlinks at higher prices. So better would be to do some R&D before creating backlinks (it must be relevant and from the relevant niche).
DA is just one of many factors that can impact a website's search engine rankings. Google uses hundreds of different ranking signals to determine the relevance and quality of a website's content, and no single factor is guaranteed to influence rankings.
Again, that is total horse manure .... DA is NOT a ranking factor used by any search engine. Why do so many continue to make this shit up for and post nonsense?
But DA is MOZ signal not of Google. When you buy a fresh domain then DA will be 1 without any activity .... if you will write few contents there and domain name is good then after few days you will see DA is 3 or 5+. I dont think also that google consider for DA when ranking a website in SERPs.
DA is just a 3rd party metric. And it's the not 2014. Good-quality content and good-quality backlinks do help.
DA is just one indicator. Changes examples of pages with artificially inflated DA and practically zero traffic.
A higher DA directly doesn't help, but it usually means higher authority, and that is what directly influences rankings. You can get higher DA by building high quality links.
