Blog on Different IP

August 27, 2008
By

Hi Jill,

I'm wondering if there is more link value provided by a new blog if it is hosted on an IP with a different C block than the IP address of the web site itself. The owner of the business would be writing the blog and sharing business expertise with the idea of building the brand of the business.

Also, in this case, the domain name could be different and include keywords.

Thanks,

Gaya

Hi Gaya,

The whole "IP on a different C block" thing is a red herring. There's no reason to worry about different C blocks unless you are attempting to trick the search engines into thinking that the blog was somehow unrelated to the website (which I don't recommend doing).

Most companies create their blog as part of their main website because it's easier for most to remember that way – e.g., www.example.com/blog. You could also make it a subdomain – e.g., blog.example.com. Either way is fine for the search engines and your users.

Hope this helps!

Best,

Jill

um, ah, maybe...
I agree if it is just going to be a company blog (other companies excluded), do it on your own domain. That approach will also add content to your domain.

However, if you blog on an industry blog site with other authors you gain 1) a reason for people to go there. 2) industry creds, and 3) assuming that blog has some some page rank, link value.

Agree, IMG, but how does this relate to the original question?
 Ken Klages said:
I agree with IMG and I think it directly relates to the question asked. If the blog is on a different domain like an industry blog site, it WILL have a different IP and will look like (and will BE) inbound links from another, independent site. So, that would seem to have some value.

I also like that fact that some of these "community" sites have so much traffic that some people might find your blog through a search on that blog community site and potentially bring new eyeballs to your site. So, I have typically recommended NOT hosting a blog on the company web site. Would you think that is a bad idea? The only negative to hosting the blog elsewhere is that the main site does not get the new content added on a regular basis from the blog, but my guess is that the external link value and exposure on a community type site is more valuable. Any thoughts on that?

I agree with Jill, you should use a folder, its better and you also will get some links value
 Jill said:
That's not actually what I said, Moda. There is no "you should" when it come to this stuff.

Every situation is different. It's a business decision, imo, not a search engine one, however.

This is sounding a lot like a microsite debate I heard at SES Chicago two years ago. There are reasons for doing it either way.

As the OP states (my emphasis added):"The owner of the business would be writing the blog and sharing business expertise with the idea of building the brand of the business."

So, IMHOP: IF the business is NEW and the main site has no traffic, no PR and no inbound links and looking to generate more in the hopes of gaining more business it would help to host the blog along with the main site.

keep it on the same domain and IP. If you have multiple sites then use different C block IPs if you can.
 Mike Shannon said:
Jill,

Aside from the IP question, you mentioned that a blog can be either domain.com/blog or blog.domain.com. As I understand it, subdomains are treated as separate domains: blog.domain.com won't add to domain.com's authority, so a new site might want to keep their blog as a directory to help consolidate their pages for ranking purposes.

 Jill said:
Mike, it typically seems that even subdomains keep the authority of the main domain, from what I've seen, although I haven't studied it much lately.

IMHO the blog is most useful for seo and improved rankings if hosted on the same server as the website, if not the same domain, because it will boost the amount of relevant, in theme content to your main website and therefore increase authoritative position...and create a situation where the website/server is updated and nurtured often
 Jill said:
@SanDiegoWebStudio sorry, but imo, what you're saying is gobbledygook.

Hi Jill,

I'm wondering if you opinion on this has changed any since this was posted (3 years ago.) Or I suppose this is one of those things one needs to test out for oneself and one's business. I'm advising most clients to put their blog on their website at www.maindomain.com/blog. I also thinks it can work to have the blog separate from the website and to some degree from the business.

For example, I have an architect colleague who has built great traffic with a blog that is separate (from his website.) He uses the blog to interview contracts and others in the industry. He strengths his personal contacts to architects and builders through the blog. He also builds good inbound links to his site from the site.

Am I missing anything? Is this an either or? Or both kind of strategy?

Many Thanks, Karen

@Karen, no my opinion hasn't changed. It's still not a search engine issue, but a business decision, like most things online!
 Karen said:
What about similar sites in one industry - like one site about a service in California, then another site about the same service, just in Florida, and a third site that is a free info blog to feed to the 2 initial sites? Since all would be competing for the same keywords, would it makes sense to have different IP addresses?
 Jill Whalen said:
@Karen, as the article states, it should be fine unless you're trying to trick the search engines into thinking the sites aren't related.

One question... My site server is on IIS and due to some restrictions I cannot use wordpress on it for the blog. I'll install WordPress on a different IP and make it look like Site.com/blog/post.aspx with some dns tweaking. Does it hurt my site in some way?

Thanks.
 Jill Whalen said:
@Helen, if you do all the technical stuff correctly, it shouldn't hurt you in anyway as it would be seamless to the search engines.

That said, I know you can install Wordpress on IIS servers. An easier way would be to do that.
 Helen Klister said:
@Jill Whalen

The IT guy is the one placing restrictions, I told him to use APE but he says he simply is not going to try installling wordpress on IIS.

Thanks.
