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."

White H1 Tag Hurting SEO?
Hi, We're having an issue with a client not wanting the H1 tag to display on their site and using an image of their logo instead. We made the H1 tag white (did not deliberately hide with CSS) and i just read an article where this is considered black hat SEO. https://www.websitemagazine.com/blog/16-faqs-of-seo The only reason we want to hide it is because it looks redundant appearing there along with the brand name logo. Does anyone have any suggestions? Would putting the brand logo image inside of an H1 tag be ok? Thanks for the help

Opinion on Gotch SEO methods & services
I would love to get you all's take on Gotch SEO. I am gearing up to link build for a site in the next several months, and have been reading up from sources other than Moz, in preparation. (Need to re-read Moz's guide, too, but I have already read it last year) I'm reading Gotch SEO's main link building method articles right now, and am wondering what you all think. Do you think they have a good approach and are generally reliable? Likewise, has anyone used their service for getting a link? What was your experience? Or if you haven't used the service, any quick takes on it?

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

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!

Rollover design & SEO
After reading this article http://www.seomoz.org/blog/designing-for-seo some questions came up from my developers. In the article it says "One potential solution to this problem is a mouse-over. Initially when viewed, the panel will look as it does on the left hand side (exactly as the designer want it), yet when a user rolls over the image the panel changes into what you see on the right hand side (exactly what the SEO wants)." My developers say" Having text in the rollovers is almost like hiding text and everyone knows in SEO that you should never hide text. "In the article he explains that it is not hidden text since its visible & readable by the engines.What are everyone's thoughts on this? Completely acceptable or iffy?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.
