Changed domains, saw significant drop in domain authority

[SteveSaf]

Hello,

A little over a month ago we switched our domain from A to B. The original was .com and the new one is at a .tech for good measure.

We have meticulously done 301 redirects page by page but there has been a massive drop in traffic and I checked here to see that we've gone from a 30 domain authority to a 9. The company is a few months over 1 year old, but we're really looking at traffic accumulated in just about 8 months for the old domain.

Is there any way to recover some of the old juice in this one other than the re-directs? Our number of backlinks have also severely dropped despite re-directs.

You can expect a domain authority drop with a new domain name. This will climb back up.

The loss of backlinks and traffic however would suggest your 301s are not complete which will impede your DA recovery.

How many 404s do you have in search console?

Thanks for the response.

Looks like we have 55 in search console that I am working on fixing now (mostly things I drafted in CMS)

Would I need to add anything I don't want indexed anymore to robots.txt?

I assume that some of the incomplete 301's might stem from this?
