Standalone Hosting Plan vs Multisite Hosting Plan for SEO?

[IsaCleanse]

I am looking to migrate my current site to Siteground so I was having a chat with the operator who is telling me that if I was to sign up a new hosting plan I would get additional SEO benefits.. can anyone confirm or deny this?

Also while on the question, do certain domain/hosting providers offer better SEO/SERP rankings and if they do can anyone recommend any in Australia in Particular?

The domain is a .com.au website

Transcript:

me: i have a website that is registered at crazydomains and Wordpress files hosted on my friends server... what would I need to do to have the domain/hosting transfered to SG?
Siteground Operator:.: Let me take a look at the website and I will provide you with a solution
me: thx
Siteground Operator:.: In this case you have two choices, you can either host it on your current plan or create a new one just for it
Siteground Operator:.: Getting a new plan will be a better choice in terms of SEO and performance
Siteground Operator:.: But you can run it on your current GrowBig as well
me: why will taht give it better SEO?
Siteground Operator:.: Because it will have its own cPanel and it will be a primary domain for it, instead of having it setup as an addon
me: How does Google know what the primary or secondary domain on my hosting plan?
Siteground Operator:.: It doest, as your file location will be primarydomain.com/addonslot
Siteground Operator:.: Compared to primarydomain.com if you put it in its own hosting plan
me: So im struggling to understand how this affects my SEO?
Siteground Operator:.: SERP is based on a couple of things, one of which is domain authority (DO). This tends to be a lot harder to build up with addon domains compared to domains hosted in their own plans.
Siteground Operator:.: Additionally, you will have 2 sites under a single IP address which is not the optimal solution you want to get
me: What would need to be done as far as transfering the WP installation/files/databse etc
Siteground Operator:.: As its stored on a local host you will have to upload a backup copy of your files and db on our server and we will configure it for you.
System: me has ended the chat

I am a big fan of SiteGround, but that is a load of rubbish.

So what you will get out of a multi-account domain hosting is all domains hosted on the same host one being the primary the rest would be add-ons. . The rep may over sold the SEO benefits in this case. However, he does have a point IMO. Lets say you have the following multi-domains on the same host plan

Flower-City.co.au (Primary)
Rose-City.co.au (Add On)
Tulip-City.co.au (Add On)

All these domains are hosted on the same server with the same name server that resolves the actual path. If Flower-City.co.au gets hit with a penalty for whatever reason the add-on domains may also suffer because technically they are on the same server, thus creating an association to a penalized domain. Additional issues like flower-city.co.au being marked as a spammer may cause the other sub-domains to be flagged as spam even if they never sent an email, simply because they are on the same server. This could actually work in the other direction as well, rose-city.co.au you get the penalty thus affecting the other domains it is associated with.

If you everything is done correctly on each domain, and no penalties are ever occurred than I can't see any reason why each domain wouldn't be able to rank and benefit from proper SEO individually.

My thoughts,

Hope it helps.
