Do you think 2.0 (Domain Authority) will affect your website and your traffic?

as we know 2.0 websites have good da and pa then it can helps us to rank our website authority

no DA is not affect your website. google not used DA for ranking.

Web 2.0 submission is the online technique (it used to work better years ago, but it still works quite good). In this way or technique, you can share your content via hubpages, squidoo, blog sites etc.

There's no evidence that search engines use Domain Rating (Domain Authority, the power of domain, etc) as a ranking factor at all. ... Therefore, a page that doesn't have any external backlinks may rank higher only because of internal links that it gets from other pages of its own domain. Checked Google!

Guys, have you ever experienced your website to get un-indexed from Google for no reason? If yes then what to do in such a case?

Not at all, your actions have the most impact

NO, AS ALL KNOW GOOGLE DOES NOT CONSIDER DA AS RANKING FACTOR SO it's NOT GOING TO AFFECT RANK.

Google does not use Domain Authority in its ranking algorithm, so I don't think DA 2.0 update will affect website traffic.

Not at all! Currently, I have seen some changes in the ranking where there were some ups and down. But as you know Google does not consider DA (domain authority) as the ranking factor, so now start focusing on the best performing sites rather than high DA PA sites.
