Multiple sites about same topic on the same server

If you are *not* interlinking them, is there any harm in having 5-6 sites on the same topic on the same server? Spread out over a few IP's.

I ask because one of them ranks very well, yet the others don't. The content is not identical...different blog posts written by me on each and passes copyscrape, yet they're about the same subject and there's only so much news to cover in this topic.

No issues with the server imo. I have 11 clients in the same industry on the same server with no ranking aberrations.

Are they doorway pages built just to rank for a specific key phrase?

URLs?

They aren't doorways, they're individual blogs. Not going to share the URL's, but they all have a different wordpress theme, different posts, etc. They just happen to be covering the same sorts of things...i.e. take Honda as an example...there would be a civic blog, an accord blog, a cr-v blog, etc. It's just that when news about Honda applies to all of them, so there would be articles about that on each of the blogs, or talking about the auto industry, etc.

Sorry brother, I am not near smart enough to diagnose this problem without seeing it. Maybe someone smarter than me?

Good luck!

I think you would be fine IF;

1. they are different class C IPs
2. the whois information (registra info) is different or private

Hi DAG,

I would like to answer you for this with my own experience and similar situation:

One of my friend in Phillipens just maintain Blogs for his earning process and all hosted on a shared IP address. He suddenly got a set back on one of the blog from search results, he thought that shared IP is a problem but actually a heavily banned website was also hosted by the service provider..

The summary of the story is:

There is no harm putting your all blog sites on one server/IP address till you take care of the following things:

1. Be particular that the shared IP is not being used by another penalized/out of SERP's by Google for any spam reason. This effects...

2. You won't interlink these blog websites and telling Google that they are supporting each other besides giving some relevant different information to the net serving people. So don't interlink tham

3. All the blogs should have quality fresh & different content which makes each blog to serve something to the net users...if you mistakenly copy content on all of them whether once, it may create problem to you

4. Try building natural links / good relevant links for your Blogs and you will definately get lot of help

5. Promote your Blog in Social Media / announce them on forums if they are really worth informative / create rss so that people can subscribe to your feed to keep updated of your latest posts.

Just don't worry, there is no such concern as you mentioned, just do the above, take care of everything and you will sooner/later get good results, sometimes we loose our patience very soon and end up making changes and changes and no result, be patient for a month with all above care, you will do well than...

P.S. This is my theory of experience, anybody can have different theory as there are no rules, just do the best..

You should be absolutely fine. It wouldn't be logical if a site was deemed less important than another just because they are on the same server and are targeting the same industry - there are bound to be thousands of sites that share the same subject on the same server out there.

From my experience I haven't seen any problems with this kind of scenario. No duplicate content and no interlinking means you should be fine.

Sorry mate for digging at you again but I don't think it was necessary to share your friend's experience - there has to be something else involved as if that was true in theory it would be easy to bring your competitors down.

Zagek, i respect your words...it's just i am very straight forward, what i experienced with my friend as we have worked together on those websites, i shared....will consider your thought in further post as we all learn something from other buddy

Not to overlook your question but I have to ask - What's the point in having different sites? Why create 5-6 subpar blog entries on a topic and post to different blogs instead of just writing one excellent entry and only maintaining one site?

My guess is he is doing something like this:

honda-seattle.com
honda-kirkland.com
honda-bellevue.com

Making a "unique" blog for the product for each city in the region. I have seen that pop up a lot more lately from the competitors of my clients.

To rank for more and different keywords with sites that are more targeted to a group of keys.

Sort of like what st0rmshadow is saying except it's not geographical, it's different products that are all made by one brand...so news about that brand applies to all of them, yet news about the products only apply to that product.

I find it much easier to get a little traffic to one site and duplicate the idea than it is to get lots of traffic to one site. Only problem is coming up with unique content for the smaller sites when sometimes the information has to overlap.

Here is an example of one of my client's competitors:

http:// www [dot] kirklandwadui [dot] com


At the bottom he lists his sites. The header nav has multiple domains mixed.

haha...I assure you I know better than to make mine THAT obviously related. None of the sites are interlinked and the wordpress themes are all different, they're just all on the same server and ip range. Also have a ton more content on each than this guy does.

Record all the urls and report it to Google... and then all the domains will be worthless, and the only way to get any one back in will be to disclose to google who was responsible for the development and all domains in asscoiation - so you can repeat the process.

Fathom & DAG,

That is what I thought. Just wanted to make sure because I have seen this crop up a lot lately in the legal industry. Many clients are law firms given my legal background. They question me often about that tactic and I have advised against it. Pushing them to develop more quality content, and improve backlinks to their sole site. Thanks for the reassurance.
