      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."

            Is domain redirection a good method for SEO?

            I have a question and need suggestion from you guys. I’ve searched for my question on Google but don’t get exact information what I need. Maybe I can’t search perfectly.
            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 much

            Does ID's in URL is good for SEO? Will SEO Submissions sites allow such urls submissions?

            Example url: http://public.beta.travelyaari.com/vrl-travels-13555-online It's our sites beta URL, We are going to implement it for our site. After implementation, it will be live on travelyaari.com like this - "https://www.travelyaari.com/vrl-travels-13555-online". We have added the keywords etc in the URL "VRL Travels". But the problems is, there are multiple VRL travels available, so we made it unique with a unique id in URL - "13555".  So that we can exactly get to know which VRL Travels and it is also a solution for url duplication. Also from users / SEO point of view, the url has readable texts/keywords - "vrl travels online". Can some Moz experts suggest me whether it will affect SEO performance in any manner? SEO Submissions sites will accept this URL? Meanwhile, I had tried submitting this URL to Reddit etc.  It got accepted.

            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,
            Mark

            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
