          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://a-moz.groupbuyseo.org/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."

                spam backlink attack spam backlinks

                Our competitor has employed the services of a spammy SEO agency that sends spammy links to our site. Though our rankings were affected we have taken the necessary steps. It is possible to send evidence to Google so that they can take down the site. I want to take this action so that other sites will not be affected by them again.

( collection/*+* ) Is this the query which is affecting the indexing product pages? Please explain me how this robots.txt work in shopify and once my page crawl and index by google.com then what is use of Disallow: Thanks.

                Can a Self-Hosted Ping Tool Hurt Your IP?

                Confusing title I know, but let me explain. We are in the middle of programming a lot of SEO "action" tools for our site. These will be available for users to help better optimize their sites in SERPs. We were thinking about adding a "Ping" tool based in PHP so users can ping their domain and hopefully get some extra attention/speed up indexing of updates. This would be hosted on a subdomain of our site. My question is: If we get enough users using the product, could that potentially get us blacklisted with Google, Bing etc? Technically it needs to send out the Ping request, and that would be coming from the same IP address that our main site is hosted on. If we end up getting over a 1000 users all trying to send ping requests I don't want to potentially jeopardize our IP. Thoughts?

                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!

                Why does expired domains still work for SEO?

                Hi everyone I’ve been doing an experiment during more than 1 year to try to see if its possible to buy expired domains. I know its considered black hat, but like I said, I wanted to experiment, that is what SEO is about. What I did was to buy domains that just expired, immediately added content on a WP setup, filled it with relevant content to the expired domain and then started building links to other relevant sites from these domains.( Here is a pretty good post on how to do, and I did it in a similar way. http://searchenginewatch.com/article/2297718/How-to-Build-Links-Using-Expired-Domains ) This is nothing new and SEO:s has been doing it for along time. There is a lot of rumors around the SEO world that the domains becomes worthless after they expire. But after trying it out during more than 1 year and with about 50 different expired domains I can conclude that it DOES work, 100% of the time. Some of the domains are of course better than others, but I cannot see any signs of the expired domains or the sites i link to has been punished by Google. The sites im liking to ranks great ONLY with those links 🙂 So to the question: WHY does Google allow this? They should be able to see that a domain has been expired right? And if its expired, why dont they just “delete” all the links to that domain after the expiry date? Google is well aware of this problem so what is stopping them? Is there any one here that know how this works technically?

                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
