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."

Hi, I am working on one big eCommerce store which have more then 1000 Product. we just moved platform WP to Shopify getting noindex issue. when i check robots.txt i found below code which is very confusing for me. **I am not getting meaning of below tags.** Disallow: /collections/+ Disallow: /collections/%2B Disallow: /collections/%2b Disallow: /blogs/+ Disallow: /blogs/%2B Disallow: /blogs/%2b I can understand that my robots.txt disallows SEs to crawling and indexing my all product pages. ( 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.

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,

Black Hat SEO Case Study - Private Link Network - How is this still working?
I have been studying my competitor's link building strategies and one guy (affiliate) in particular really caught my attention. He has been using a strategy that has been working really well for the past six months or so. How well? He owns about 80% of search results for highly competitive keywords, in multiple industries, that add up to about 200,000 searches per month in total. As far as I can tell it's a private link network. Using Ahref and Open Site Explorer, I found out that he owns 1000s of bought domains, all linking to his sites. Recently, all he's been doing is essentially buying high pr domains, redesigning the site and adding new content to rank for his keywords. I reported his link-wheel scheme to Google and posted a message on the webmaster forum - no luck there. So I'm wondering how is he getting away with this? Isn't Google's algorithm sophisticated enough to catch something as obvious as this? Everyone preaches about White Hat SEO, but how can honest marketers/SEOs compete with guys like him? Any thoughts would be very helpful. I can include some of the reports I've gathered if anyone is interested to study this further. thanks!

Would having a + plus sign between keywords in meta title have an effect on SEO?
I have seen one of my clients' competitors do this in their meta title and it got me a little intrigued... I understand that google uses the + sign as an operator in adwords, and to a certain extent, as a search tool, but would it help or make any difference to the SEO in the meta title/data (eg. 'SEO+Marketing+Services')? Thanks

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
