The benefits from having a dedicated IP
-
Is the true? Claim by SiteGround
Having a dedicated IP for each website is considered by some experts as an advantage for search engine optimization. There is a common believe that sites with dedicated IP addresses do better in the search engine results than those on shared IPs. Such sites do not share the risk of being banned for sharing the same IP in case another website hosted on the same server gets banned by a search engine.

I have 7-8 ad-sense blog websites under one hosting, Now I am planing to create selling website. My blogs were not having good content and they are decreasing in ranking (my be panda). So I need to remove those websites from the hosting? should they effect my new selling website negatively?

In the great Google infrastructure, I'm sure that Google knows what IP address your site is hosted on, and all the ones tied to it. In one of the past MOZ blog posts you can see a number of factors Google looks at to see what you control. We used dedicated IP's for each client, just in case anything ever happened to one account, it would not affect the others. They are close in IP address range, since they are on the same block, but none are on the same number. This isn't an attempt to gain SEO rank, as much as it is to protect the client.
Locally, I have reason to believe its a different story. For example, we are located in St Louis, and use a local server center located in downtown St Louis. After changing our site from hostgator under a shared IP, (Provo, Utah) to a local server center, we saw an drastic (in internet time) improvement in site load time, responsiveness, and believe it or not, a ranking boost....true story, no joke. It wasn't a large boost, but we moved up 2 spots on our main keyword on page one, and 1-2 in other places. We didn't make any other changes to the site, other than adding a few blog posts, and this was not around any major algorithm shift or update. We have seen this pattern repeat with other clients as well.
My guess is that Google liked the decreased load times, the local server location (as it matched the city on our site, somehow verifying our location further), and the fact that the site was on a dedicated IP address. If we had just changed the site's IP address by itself, I do not think we would have seen any impact or result change.
"there is really no SEO benefit of having a unique IP for each of your sites unless you're attempting to pass link juice between each, which falls into the greyhat category."
I don't think you would get away with this for very long, or that it would benefit you in any way. Google would see that you host or control these sites through your analytics account, or IP range. If you wanted to pull it off, and have separate analytics accounts, dedicated IP's etc, I doubt the result would be worth the time.

Depending on what your site's purpose is, I have to respectfully disagree with the above comments. If you're site is selling something, you need an SSL certificate, and (I'm reasonably) certain, you can't have that without a dedicated IP address. All things equal, e-commerce sites with an SSL certificate will rank higher than sites without one. Plus, there are other non-seo benefits to a dedicated ip address, and it's inexpensive. To me it's a no-brainer, but I understand why people would disagree.

Google bans sites (domain names) rather than IP addresses. However if you are thinking of moving your site so https then you would need a dedicated IP address. Yoast has published an interesting article here Moving your website to https / SSL: tips & tricks perhaps that's what they are referring to.

I agree with Bill, there is really no SEO benefit of having a unique IP for each of your sites unless you're attempting to pass link juice between each, which falls into the greyhat category.

Nope, as far as I know. Matt Cutt's commented on it https://www.youtube.com/watch?v=AsSwqo16C8s
The only time I could see it was useful if you were doing some black hatish stuff and didn't want multiple domains on the same C Block that were related, but I'm pretty sure Penguin/ Panda is catching that sort of thing now.

What IP Address does Googlebot use to read your site when coming from an external backlink?
Hi All, I'm trying to find more information on what IP address Googlebot would use when arriving to crawl your site from an external backlink. I'm under the impression Googlebot uses international signals to determine the best IP address to use when crawling (US / non-US) and then carries on with that IP when it arrives to your website? E.g. - Googlebot finds www.example.co.uk. Due to the ccTLD, it decides to crawl the site with a UK IP address rather than a US one. As it crawls this UK site, it finds a subdirectory backlink to your website and continues to crawl your website with the aforementioned UK IP address. Is this a correct assumption, or does Googlebot look at altering the IP address as it enters a backlink / new domain? Also, are ccTLDs the main signals to determine the possibility of Google switching to an international IP address to crawl, rather than the standard US one? Am I right in saying that hreflang tags don't apply here at all, as their purpose is to be used in SERPS and helping Google to determine which page to serve to users based on their IP etc. If anyone has any insight this would be great.

SEO impact of 301 redirects based on IP addresses from a specific state
Hello Moz Community! We are facing an issue that may or may not be unique, but need some advice and/or clarification on the best way to address the issue. We recently rebranded and launched a new site under a new domain and things have been progressing well. However, despite all the up front legwork on trademarks and licensing, we have recently encountered a hiccup that forces us to revert to the old URL/branding for one specific state. This may be a temporary issue that lasts a couple of months or it could potentially be in the court system for a couple of years. One potential solution we have discussed is to redirect the new site to the old site based on IP addresses for the state in question. Looking for any guidance on what type of impact this may have on SEO. Also open to any other suggestions or guidance on dealing with this situation. Thanks

Does blocking foreign country IP traffic to site, hurt my SEO / US Google rankings?
I have a website is is only of interest to US visitors. 99% (at least) of Adsense income is from the US. But I'm getting constant attempts by hackers to login to my admin account. I have countermeasures fo combat that and am initiating others. But here's my question: I am considering not allowing any non US, or at least any non-North American, traffic to the site via a Wordpress plugin that does this. I know it will not affect my business negatively, directly. However, are there any ramifications of the Google bots of these blocked countries not being able to access my site? Does it affect the rankings of my site in the US Google searches. At the very least I could block China, Russia and some eastern European countries.

If I own a .com url and also have the same url with .net, .info, .org, will I want to point them to the .com IP address?
I have a domain, for example, mydomain.com and I purchased mydomain.net, mydomain.info, and mydomain.org. Should I point the host @ to the IP where the .com is hosted in wpengine? I am not doing anything with the .org, .info, .net domains. I simply purchased them to prevent competitors from buying the domains.

Duplicate internal links on page, any benefit to nofollow
Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!

Serving different content based on IP location
I have city centric website. For sake of simplicity, say I only have 2 cities -- City A and City B. Depending on a user's IP address, they will either get City A or City B. Users can change their location through javascript on pages. But there is no cross-linking between cities. By this, I mean that unless you can read or execute javascript, there is no way for you to get from city A to City B. My concern is this: googlebot comes to my site, and we serve them up City A. How does City B get discovered if Googlebot doesn't read javascript? We have an xml sitemap plus plenty of backlinks to City B. Is this sufficient? Should I provide a static link to City B (and vice versa) on the homepage for crawling purposes?

Can I Improve Organic Ranking by Restrict Website Access to Specific IP Address or Geo Location?
I am targeting my website in US so need to get high organic ranking in US web search. One of my competitor is restricting website access to specific IP address or Geo location. I have checked multiple categories to know more. What's going on with this restriction and why they make it happen? One of SEO forum is also restricting website access to specific location. I can understand that, it may help them to stop thread spamming with unnecessary Sign Up or Q & A. But, why Lamps Plus have set this? Is there any specific reason? Can I improve my organic ranking? Restriction may help me to save and maintain user statistic in terms of bounce rate, average page views per visit, etc...
