Can i do 301 redirect of such sub domain to my www.domain.com  to get link juice to homepage will it be good idea ? Is it good to redirect a subdomain to homepage url if that donot exists anymore?

Will it cause any google issue or it shall be Google friendly ?

Hello, I have a website having many subdomains having same copy of content i think its harming my SEO for that site since abc and xyz sub domains do have same contents.

Thus i require to know i have already deleted required subdomain DNS RECORDS now how to have those pages removed from Google index as  well ?

The DNS Records no more exists for those subdomains already.

Hello,

I recently faced issue of Google recent algo update on my main website. I found my ranks were all of 5th to 7th page even with website name without .com at end we have 5th page shown our biz website. It was a news portal and behind in subdomain i was running my web hosting website.

1. I removed all news content from my website since i thought the news agency send me content send same content to others may cause in the issue so i removed the NEWS AREA

2. I am turn off all of my old subscriptions or membership of blog networks etc. to make sure i get proper good backlinks with good research etc.

Is there anybody who can suggest me what shall i take more action ? Mean any kind of further good suggestion i will highly appreciate if anyone can help me with any suggestions of SEO. I know there are many people who knows lots about it thus i thought to ask to community..

I am also unsure its a Google panelty or a Google recent update negative changes to my website ?

However i have already filled reconsideration request as an possible alternative by explaining google that we are no more NEWS CONTENT Website.

Will wait for responses...
