Does IP Blacklist cause SEO issues?
-
Hi,
Our IP was recently blacklisted - we had a malicious script sending out bulk mail in a Joomla installation.
Does it hurt our SEO if we have a domain hosted on that IP?
Any solid evidence?
Thanks.

It's not related to Gmail. The server itself was sending out email spam (Joomla is a CMS program used to manage websites). I bet he means he got listed on Spamhaus.
First off, web spam and email spam are two entirely separate things. So you can be blacklisted with anyone in the email realm and not have it affect your SEO.
Second, I've heard the "blacklisted IP" theory regurgitated for nearly 10 years now and nobody has ever proven that a specific IP was the reason for a site losing ranking. So you could, in theory, share an IP with an entire link farm and not lose any ranking (consider how many blogs share an IP under Wordpress.com or Blogspot). Google surfs the web just like everyone else (using DNS lookups) and they rank domains, not IPs (which are subject to change). The only way I could see an IP getting you in trouble is if your server got hacked and the hacker was using it to proxy attacks against Google (as in DDoS attacks, not spam). Then you might have some issues with SEO but your server being hacked would be a far more serious problem at that point.

Who has Blacklisted the IP Address. Is it Joomla forums or Gmail Account
However, as referred in this article :- http://moz.com/ugc/the-penguin-update-how-google-identifies-spam about spam emails
"So what about websites? Wouldn't that knowledge of identifying and classifying spam be shared with the search and webspam teams? Don't you think Matt Cutts has access to Gmail's spam detection data? I bet he does, and I bet some of it is being seen in this Penguin update.
Gmail is a pretty well documented product. You can read up quite a bit on spam filters and how they work. I would recommend this to everyone as we can then get a better idea of what Google sees as spam content. For me the biggest takeaway is that Gmail openly admits to using user data and feedback in classifying and identifying spam. This should be a huge indicator to us all that user data is playing a role in how Google classifies and identifies spam on the web. The trick now is to figure out exactly what user data/feedback is being used."

Does type of hosting affect SEO rankings?
Hello, I was wondering if hosting on shared, versus VPS, versus dedicated ... matter at all in terms of the rankings of Web sites ... given that all other factors would be exactly equal. I know this is a big question with many variables, but mainly I am wondering if, for example, it is more the risk of resource usage which may take a site down if too much traffic and therefore make it un-crawlable if it happens at the moment that a bot is trying to index the site (factoring out the UX of a downed site). Any and all comments are greatly appreciated! Best regards,

How to make second site in same niche and do white hat SEO
Hello, As much as we would like, there's a possibility that our site will never recover from it's Google penalties. Our team has decided to launch a new site in the same niche. What do we need to do so that Google will not mind us having 2 sites in the same niche? (Menu differences, coding differences, content differences, etc.) We won't have duplicate content, but it's hard to make the sites not similar. Thanks

The use of a ghost site for SEO purposes
Hi Guys, Have just taken on a new client (.co.uk domain) and during our research have identified they also have a .com domain which is a replica of the existing site but all links lead to the .co.uk domain. As a result of this, the .com replica is pushing 5,000,000+ links to the .co.uk site. After speaking to the client, it appears they were approached by a company who said that they could get the .com site ranking for local search queries and then push all that traffic to .co.uk. From analytics we can see that very little referrer traffic is coming from the .com. It sounds remarkably dodgy to us - surely the duplicate site is an issue anyway for obvious reasons, these links could also be deemed as being created for SEO gain? Does anyone have any experience of this as a tactic? Thanks, Dan

Adult Toy Store SEO
Hi fellows, I'm not so strange to SEO. I have been promoting our spiritual network through SEO and we have received great returns from it. I'm planning to promote an adult toy store via SEO. I have never done any adult store promoting before but I think there are a lot of down sides to it, such as: #1 When I search related keywords many porn websites show up; I assume it seems spammy to google's eye. Also most of the links that I will get are probably from porn websites due to relevancy. #2 Many of our returning customers are coming from retargeting but I assume there is no adult promotion via google display. Is that right? (It's not SEO related) I'm wondering to know if google is against adult content in any way? Any feedbacks are appreciated.

Sitelinks Search Box impact for SEO
I am wondering how the relatively new sitelinks search box impacts the SEO rankings for a specific site or keyword combination - do you guys have any experience or bechmarks on this? Obviously it should help on getting more real estate on the SERP page (due to adding the search box), but do you also get extra goodwill and improved SERP position from adding it? Also, is the impact different on different type of terms, let's say single brand or category term such as "Bestbuy" (or "coupon") or a combination term "Bestbuy Apple" (or "Dixons coupon")? Thanks in advance!

Footer Link in International Parent Company Websites Causing Penalty?
Still waiting to look at the analytics for the timeframe, but we do know that the top keyword dropped on or about April 23, 2012 from the #1 ranking in Google - something they had held for years, and traffic dropped over 15% that month and further slips since. Just looked at Google Webmaster Tools and see over 2.3MM backlinks from "sister" compainies from their footers. One has over 700,000, the rest about 50,000 on average and all going to the home page, and all using the same anchor text, which is both a branded keyword, as well as a generic keyword, the same one they ranked #1 for. They are all "nofollows" but we are trying to confirm if the nofollow was before or after they got hit, but regardless, Google has found them. To also add, most of sites are from their international sites, so .de, .pl, .es, .nl and other Eurpean country extensions. Of course based on this, I would assume the footer links and timing, was result of the Penguin update and spam. The one issue, is that the other US "sister" companies listed in the same footer, did not see a drop, in fact some had increase traffic. And one of them has the same issue with the brand name, where it is both a brand name and a generic keyword. The only note that I will make about any of the other domains is that they do not drive the traffic this one used to. There is at least a 100,000+ visitor difference among the main site, and this additional sister sites also listed in the footer. I think I'm on the right track with the footer links, even though the other sites that have the same footer links do not seem to be suffering as much, but wanted to see if anyone else had a different opinion or theory. Thanks!

Interesting case of IP-wide Google Penalty, what is the most likely cause?
Dear SEOMOZ Community, Our portfolio of around 15 internationalized web pages has received a significant, as it seems IP-wide, Google penalty starting November 2010 and have yet to recover from it. We have undergone many measure to lift the penalty including reconsideration requests wo/ luck and am now hoping the SEOMoz community can give us some further tips. We are very interested in the community's help and judgement what else we can try to uplift the penalty. As quick background information, The sites in question offers sports results data and is translated for several languages. Each market, equals language, has its own tld domain using the central keyword, e.g. <keyword_spanish>.es <keyword_german>.de <keyword_us>.com</keyword_us></keyword_german></keyword_spanish> The content is highly targeted around the market, which means there are no duplicate content pages across the domains, all copy is translated, content reprioritized etc. however the core results content in the body of the pages obviously needs to stay to 80% the same A SEO agency of ours has been using semi-automated LinkBuilding tools in mid of 2010 to acquire link partnerships There are some promotional one-way links to sports-betting and casino positioned on the page The external linking structure of the pages is very keyword and main-page focused, i.e. 90% of the external links link to the front page with one particular keyword All sites have a strong domain authority and have been running under the same owner for over 5 years As mentioned, we have experienced dramatic ranking losses across all our properties starting in November 2010. The applied penalties are indisputable given that rankings dropped for the main keywords in local Google search engines from position 3 to position 350 after the sites have been ranked in the top 10 for over 5 years. A screenshot of the ranking history for one particular domain is attached. The same behavior can be observed across domains. Our questions are: Is there something like an IP specific Google penalty that can apply to web properties across an IP or can we assume Google just picked all pages registered at Google Webmaster? What is the most likely cause for our penalty given the background information? Given the drops started already in November 2010 we doubt that the Panda updates had any correlation t this issue? What are the best ways to resolve our issues at this point? We have significant history data available such as tracking records etc. Our actions so far were reducing external links, on page links, and C-class internal links Are there any other factors/metrics we should look at to help troubleshooting the penalties? After all this time wo/ resolution, should we be moving on two new domains and forwarding all content as 301s to the new pages? Are the things we need to try first? Any help is greatly appreciated. SEOMoz rocks. /T cxK29.png

Ever seen a black hat SEO hack this sneaky?
A friend pointed out to me that a University site had been hacked and used to gain top Google rankings. But it was cloaked so that most users wouldn't notice the hack. Only Googlebot and visitors from Google SERPs for the spam keywords would see a hacked version. See http://www.rypmarketing.com/blog/122-how-hackers-gained-an-easy-1-google-ranking-using-a-university-website.whtml (my blog) for screenshot and specifics. I've dealt with hacks before, but nothing this evil and sneaky. Ever seen anything like this? This is not our client, but was just curious if others had seen a hack like this before.
