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."

Unique page URLs and SEO titles
www.heartwavemedia.com / Wordpress / All in One SEO pack I understand Google values unique titles and content but I'm unclear as to the difference between changing the page url slug and the seo title. For example: I have an about page with the url "www.heartwavemedia.com/about" and the SEO title San Francisco Video Production | Heartwave Media | About I've noticed some of my competitors using url structures more like "www.competitor.com/san-francisco-video-production-about" Would it be wise to follow their lead? Will my landing page rank higher if each subsequent page uses similar keyword packed, long tail url? Or is that considered black hat? If advisable, would a url structure that includes "san-francisco-video-production-_____" be seen as being to similar even if it varies by one word at the end? Furthermore, will I be penalized for using similar SEO descriptions ie. "San Francisco Video Production | Heartwave Media | Portfolio" and San Francisco Video Production | Heartwave Media | Contact" or is the difference of one word "portfolio" and "contact" sufficient to read as unique? Finally...am I making any sense? Any and all thoughts appreciated...

Asynchronous loading of product prices bad for SEO?
We are currently looking into improving our TTFB on our ecommerce site. A huge improvement would be to asynchronously load the product prices on the product list pages. The product detail page – on which the product is ordered- will be left untouched. The idea is that all content like product data, images and other static content is sent to the browser first(first byte). The product prices depend on a set of user variables like delivery location, vat inclusive/exclusive,… etc. So they would requested via an ajax call to reduce the TTFB. My question is whether google considers this as black hat SEO or not?

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

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

How Is Your Approach Towards Adult SEO?
I would like to know how SEOMoz community members approach adult SEO. How do you approach a project when you get one (if you do it that is). If you dont do adult SEO, why do you not do it? Is it because it's much more difficult than normal SEO or do you not want to associate yourself with that industry?

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
