      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."

            Moz was unable to crawl your site? Redirect Loop issue

            Moz was unable to crawl your site on Jul 25, 2017. I am getting this message for my site: It says "unable to access your homepage due to a redirect loop. https://kuzyklaw.com/ Site is working fine and last crawled on 22nd July. I am not sure why this issue is coming. When I checked the website in Chrome extension it saysThe server has previously indicated this domain should always be accessed via HTTPS (HSTS Protocol). Chrome has cached this internally, and did not connect to any server for this redirect. Chrome reports this redirect as a "307 Internal Redirect" however this probably would have been a "301 Permanent redirect" originally. You can verify this by clearing your browser cache and visiting the original URL again. Not sure if this is actual issue, This is migrated on Https just 5 days ago so may be it will resolved automatically. Not sure, can anybody from Moz team help me with this?

            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!

            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

            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

            Recovering From Black Hat SEO Tactics

            A client recently engaged my service to deliver foundational white hat SEO. Upon site audit, I discovered a tremendous amount of black hat SEO tactics employed by their former SEO company. I'm concerned that the efforts of the old company, including forum spamming, irrelevant backlink development, exploiting code vulnerabilities on BB's and other messy practices, could negatively influence the target site's campaigns for years to come. The site owner handed over hundreds of pages of paperwork from the old company detailing their black hat SEO efforts. The sheer amount of data is insurmountable. I took just one week of reports and tracked back the links to find that 10% of the accounts were banned, 20% tagged as abusive, some of the sites were shut down completely, WOT reports of abusive practices and mentions on BB control programs of blacklisting for the site. My question is simple. How does one mitigate the negative effects of old black hat SEO efforts and move forward with white hat solutions when faced with hundreds of hours of black gunk to clean up. Is there a clean way to eliminate the old efforts without contacting every site administrator and requesting removal of content/profiles? This seems daunting, but my client is a wonderful person who got in over her head, paying for a service that she did not understand. I'd really like to help her succeed. Craig Cook
