redirecting domain to main website, SEO?

Hello,

I recently got myself some EMD domains that still had a DA/PA of around 10.
The backlinks where not spammy and the domains had my keywords in it.

Now i basically redirect them to my main website pages.

For example:
The domain i want to redirect is: dogs.com
I redirect it to: mywebsite.com/dogs

Example 2:
The domain i want to redirect is: cats.com
I redirect it to: mywebsite.com/cats

I did this trough DNS management and setted up a redirect.
Now all redirections are working so was that basically it for this small SEO step?

I read allot about 301 etc.. but never saw that number coming while setting all redirections up so not sure if I did it correct.

Thank you all

DNS redirection is done by your host using some kind of script. You need to find out whether it's really 301 by debugging the redirect.

On linux you can do a HEAD command on your url to see how it's redirecting.

On your browser you can set the sticky mode for the network console and see the redirect there too.

I prefer to host my own domains and then redirect them myself, that way I control the entire process.

Try this: http://www.redirect-checker.org/ and check if it's 301. If it is then you are set.

I think you should probably setup 301 redirect in a proper manner, so that when any search engine spider comes to the emd, it will read as 301 and then dutifully redirected to the right page, and hence preserving the link juice to flow to your intended page.
There are other redirect options as well, like javascript or dns - I can vouch for javascript, but link juice may be 50-70% max efficiency -- not sure about the dns.
