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."

Let me explain my confusion:
I’ve checked backlink profile of a website. He is not using his main domain while doing comment backlink. He put his another domain while doing comment backlink. The another domain redirect to the main domain. Why he use another domain while doing comment backlink?
Is it helpful to get better rank on Google? For example: My Main Domain = solutionfall.com
Another Domain= xyz.com (It redirect to solutionfall.com)
He just uses xyz.com while doing comment backlink. Thank You so much1 -
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

href="#" and href="javascript.void()" links. Is there a difference SEO wise?
I am currently working a site re-design and we are looking at if href="#" and href="javascript.void()" have an impact on the site? We were initially looking at getting the links per page down but I am thinking that rel=nofollow is the best method for this. Anyone had any experience with this? Thanks in advanced

Backlinks for the same IP address
Hi Everyone I've been doing a backlink clean up as my site has dropped quite a lot in the search engine results over the last 4 months. While doing the backlink clean up I cam e across 20 different domains all based in the Washington/ VA area all with the same IP address. To make matters worse the contents and link to my site are all duplicated. Is this seen as bad practice from Google's perspective i.e. a link network.?? I look forward to hearing you comments Many thanks Jonathan

Off-page SEO and link building
Hi everyone! I work for a marketing company; for one of our clients' sites, we are working with an independent SEO consultant for on-page help (it's a large site) as well as off-page SEO. Following a meeting with the consultant, I had a few red flags with his off-page practices – however, I'm not sure if I'm just inexperienced and this is just "how it works" or if we should shy away from these methods. He plans to: guest blog do press release marketing comment on blogs He does not plan to consult with us in advance regarding the content that is produced, or where it is posted. In addition, he doesn't plan on producing a report of what was posted where. When I asked about these things, he told me they haven't encountered any problems before. I'm not saying it was spam-my, but I'm more not sure if these methods are leaning in the direction of "growing out of date," or the direction of "black-hat, run away, dude." Any thoughts on this would be crazy appreciated! Thanks, Casey

Negative SEO - Case Studies Prove Results. De-rank your competitors
Reading these two articles made me feel sick. People are actually offering a service to de-rank a website. I could have swore I heard Matt Cutts say this was not possible, well the results are in. This really opens up a whole new can of worms for google. http://trafficplanet.com/topic/2369-case-study-negative-seo-results/ http://trafficplanet.com/topic/2372-successful-negative-seo-case-study/ This is only going to get worse as news like this will spread like wildfire. In one sense, its good these people have done this to prove it to google its just a pity they did it on real business's that rely on traffic.

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
