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."

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.

How to make second site in same niche and do white hat SEO
Hello, As much as we would like, there's a possibility that our site will never recover from it's Google penalties. Our team has decided to launch a new site in the same niche. What do we need to do so that Google will not mind us having 2 sites in the same niche? (Menu differences, coding differences, content differences, etc.) We won't have duplicate content, but it's hard to make the sites not similar. Thanks

Negative SEO Click Bot Lowering My CTR?
I am questioning whether one of our competitors is using a click bot to do negative SEO on our CTR for our industry's main term. Is there any way to detect this activity? Background: We've previously been hit by DoS attacks from this competitor, so I'm sure their ethics/morals wouldn't prevent them from doing negative SEO. We sell an insurance product that is only offered through broker networks (insurance agents) not directly by the insurance carriers themselves. However, our suspect competitor (another agency) and insurance carriers are the only ones who rank on the 1st page for our biggest term. I don't think the carrier sites would do very well since they don't even sell the product directly (they have pages w/ info only) Our site and one other agency site pops onto the bottom of page one periodically, only to be bumped back to page 2. I fear they are using a click bot that continuously bounces us out of page 1...then we do well relatively to the other pages on page 2 and naturally earn our way back to page 1, only to be pushed back to page 2 by the negative click seo...is my theory. Is there anything I can do to research whether my theory is right or if I'm just being paranoid?

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!

Footer Link in International Parent Company Websites Causing Penalty?
Still waiting to look at the analytics for the timeframe, but we do know that the top keyword dropped on or about April 23, 2012 from the #1 ranking in Google - something they had held for years, and traffic dropped over 15% that month and further slips since. Just looked at Google Webmaster Tools and see over 2.3MM backlinks from "sister" compainies from their footers. One has over 700,000, the rest about 50,000 on average and all going to the home page, and all using the same anchor text, which is both a branded keyword, as well as a generic keyword, the same one they ranked #1 for. They are all "nofollows" but we are trying to confirm if the nofollow was before or after they got hit, but regardless, Google has found them. To also add, most of sites are from their international sites, so .de, .pl, .es, .nl and other Eurpean country extensions. Of course based on this, I would assume the footer links and timing, was result of the Penguin update and spam. The one issue, is that the other US "sister" companies listed in the same footer, did not see a drop, in fact some had increase traffic. And one of them has the same issue with the brand name, where it is both a brand name and a generic keyword. The only note that I will make about any of the other domains is that they do not drive the traffic this one used to. There is at least a 100,000+ visitor difference among the main site, and this additional sister sites also listed in the footer. I think I'm on the right track with the footer links, even though the other sites that have the same footer links do not seem to be suffering as much, but wanted to see if anyone else had a different opinion or theory. 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.
