Is it better to park / alias a domain or have a simple one page redirect?
I have several domains that just need to direct to a main site and don't want duplicate content issues or to hurt any SEO benefits.

Do you think it's better to do a basic 1 page that refreshes to the main site or just park / alias it over as far as SEO and Google is concerned?

I used to do this but in 2018 google changed the algorithm so i'm not sure it will work
 
Post a web page and make it a permanent link to your site. Parking is like having nothing there. Zero score for search engines.

dont have a redirect page to the main website - that will hurt SEO - Rather park your domain - and that way you can make revenue too with the park domains through adsense/any other network.

Hope this helps...

I recommend to set 301 redirect to main domain. I guess that what you need .
 

Thanks, seems there is no definitive best option. I'll post any updates I get here.
