Will multiple domains from the same company rank for the same keyword search?

[RG_SEO]

I'm trying to convince people that we need good marketing reasons for starting multiple domains, as it will be more difficult to rank multiple sites. Does anyone know if Google actively discourages multiple domains from the same company appearing in the search results for the same keyword? We are creating a separate content website which is related to an existing company website. Would you agree that is best to have these sites on one domain with the content site on a sub-domain perhaps? I'm worried about duplication of effort and cross-keyword targeting in particular.

These sites would not have duplicate content.

you took offense for how I communicated, and for that I apologize.  However if you read the opening of my initial response, I stated that what I was going to write was a more complete response because over-simplification is very dangerous in our industry. People make jumps and leaps of assumption all too often when they don't have a more thorough understanding of the nuances of acceptable vs unacceptable.

As you yourself pointed out, there are perfectly legitimate reasons for owning multiple domains that all rank for the same term (ex: nike.com, nikeinc.com, nikeplus.com, etc). Not sure why you are arguing with what I wrote.

this is a matter of semantics. Attempting to rank multiple sites for the same phrase IS a spam tactic, and thus a site WILL be penalized for it if that's the intent. I've done audits on enough sites that had been penalized and came to me for help as a result that I know this to be true.

Where in Google's TOS does it say that ranking multiple domains for the same phrases is against the guidelines? My original answer is correct: Google will not penalize you for owning multiple domains, only if you are being spammy about it.

Actually the correct deeper answer based on both Google policies and SEO best practices is as follows:

1. It is directly against Google's terms of service to attempt to rank multiple sites for the same phrases.
2. When you have more than one site that contains content that directly competes against any other site, whether its a site you own or someone else owns, or even other content on your own site, Google's multi-algorithm system attempts to determine which site deserves the higher ranking for a particular phrase or search query.  In that process their system attempts to then determine whether any of those shouldn't even be indexed, let alone show up in search results.
3. Based on these considerations, any of your content could quite possibly suffer from either a loss of position it should otherwise deserve, or even have some or all of its content deindexed.  And in a worst case scenario, you could be penalized as well.

SO - the only issue then is this - WHY would you want multiple sites? Do any of the following reasons match your vision? If so, then you CAN have multiple sites IF they are done properly.

A) If you've got a big active brand, with a lot of customers/clients, it can help to create multiple sites often including:

• Corporate Site
• eCommerce Site
• Careers Site
• Community Site
• Charitable Giving Site
• Customer Support Site

B) If you have specific separate and quite distinctly different service or product offerings, you can create multiple sites so that the very different topical intent of each site is kept uniquely refined in that specific funnel and doesn't "pollute" or "dilute" the umbrella topical focus of each niche.

C) If you have an eCommerce site (where intent is online sales) you may have a desire to have a separate community or blog site (where intent is informational) as another way to keep the "intent" funnels cleanly separated.

NOTE:

It is VITAL that you understand the concept that when executed properly, multiple sites are very useful. However, these need to factor in the following:

1. Every site needs to be able to pass the "5 Super-Signals" test:

• Quality
• Uniqueness
• Authority
• Relevance
• Trust

In regard to the above, content needs to be truly unique across each site. While you can have similar content specific to your brand identity, and even some similarity about the umbrella topic of your product or service offerings, this needs to be done in a way that does not violate the "multiple sites for ranking domination" except as it relates to your brand (as opposed to generic non-brand product or service offerings).

2. Each site needs to have a LEGITIMATE business case reason for its existence not considering SEO - the "why this site exists" question needs to pass muster.

3. Every additional site you create requires its own consistent quality effort, as well as trustworthy off-site reinforcement. If a proper concerted effort cannot be maintained over the long-haul on multiple sites, it is much wiser to go with one single unified site.

Google won't actively penalize you for owning multiple domains, unless you are going out of your way to be spammy about it. However, you will need a lot more resources in terms of link building, social media promotion, content production, etc.

In general, the best practice from an SEO perspective is to have a single site with the all the content living in subdirectories of the domain. Subdomains are considered in many cases to be separate sites, so you would run into the same issues as having multiple domains.
