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."

Should I Report A SEO Agency to Google
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.

White H1 Tag Hurting SEO?
Hi, We're having an issue with a client not wanting the H1 tag to display on their site and using an image of their logo instead. We made the H1 tag white (did not deliberately hide with CSS) and i just read an article where this is considered black hat SEO. https://www.websitemagazine.com/blog/16-faqs-of-seo The only reason we want to hide it is because it looks redundant appearing there along with the brand name logo. Does anyone have any suggestions? Would putting the brand logo image inside of an H1 tag be ok? Thanks for the help

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?

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...

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!

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

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.
