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://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."

Old subdomains - what to do SEO-wise?
Hello, I wanted the community's advice on how to handle old subdomains. We have https://www.yoursite.org. We also have two subdomains directly related to the main website: https://www.archive.yoursite.org and https://www.blog.yoursite.org. As these pages are not actively updated, they are triggering lots and lots of errors in the site crawl (missing meta descriptions, and much much more). We do not have particular intentions of keeping them up-to-date in terms of SEO. What do you guys think is the best option of handling these? I considered de-indexing, but content of these page is still relevant and may be useful - yet it is not up to date and it will never be anymore. Many thanks in advance.

Hiding Elements on Mobile. Will this effect SEO.
Hey guys and gals, I am hiding elements with @media sizes on the mobile experience for this site. http://prepacademyschools.org/ My question is when hiding elements from mobile, will this have a negative effect on rankings for mobile and or desktop? Right now it is a hero banner and testimonial. My interest is because I feel responsive is now working against conversions when it comes to mobile because desktop typically has the same info several times where mobile it can be repetitive and only needed once. Thanks,

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?

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,

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?

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

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
