Site being targeted by hardcore porn links
-
We noticed recently a huge amount of referral traffic coming to a client's site from various hard cord porn sites. One of the sites has become the 4th largest referrer and there are maybe 20 other sites sending traffic.
I did a Whois look up on some of the sites and they're all registered to various people & companies, most of them are pretty shady looking.
I don't know if the sites have been hacked or are deliberately sending traffic to my client's site, but it's obviously a concern. The client's site was compromised a few months ago and had a bunch of spam links inserted into the homepage code.
Has anyone else seen this before? Any ideas why someone would do this, what the risks are and how we fix it?
All help & suggestions greatly appreciated, many thanks in advance.

"in a case like this is it sensible to preemptively remove the links with the disavow tool?"
Once again, the Disavow tool was offered as a last resort by Google. Many webmasters seem frustrated the tool is not working as they expected, and the issue is typically they ignored Google's instructions for the tool's usage.
Prior to using the Disavow tool, you need to make an exhaustive effort to remove the links. Send a polite letter to the WHOIS address for the domain explaining the problem and identifying specific links from that domain which are pointing to your site. If there is no response within 3 days, send the same letter to an email address found on the site itself. If you still do not receive a response, check for a Contact Form on the site.
Try to learn what is going on with the site. Ask site owners how these links were created. It surely can be the result of negative SEO, but in the overwhelming majority of cases I have worked with, it is either the client or an agent acting on behalf of the client. Try digging a little deeper.

Hi again Ryan/Gordon,
Sorry to bring this one up again, but we could use some more input if possible. It turns out the number of referring URLs is way higher than we originally thought. I've also done some digging in OSE and have found a huge number of links from dubious sources. It's going to take some time to refine the list but we're probably looking in the thousands.
There's no doubt that this is malicious as we have never done anything to build links like these.
We've not yet noticed any penalty or received any warnings but in a case like this is it sensible to preemptively remove the links with the disavow tool?
One other thought: it seems suspicious that this has happened around the same time that the site itself was hacked with similar links inserted into the homepage.
My best guess is that the site hasn't been specifically targeted but has been caught up in some kind of automated spam attack. I've looked at some of the other offending sites and all the links are in odd places - hidden in the code or in strange anchor text. Is it possible that a robot has crawled all these sites and inserted spam links to create some kind of massive "link wheel"?
In this case what's the best preemptive solution before we get slapped with a penalty?
Thanks again...

There are not any general endorsements I can share. Your chosen expert may vary depending on your hosting environment, site software and budget.

I appreciate your time & help Ryan. I will pass all those suggestions on.
If they choose to bring in a security expert in to take a look, do you have any recommendations?

"As for the client's site hacking, as far as I'm aware their webmaster & in-house team dealt with that when it happened."
The webmaster and inhouse team likely had a gap which was exploited. It may be best to bring in an outside security consultant to review the matter.
"if our messages go unacknowledged, what else can we do about it?"
In my experience, 25 - 60% of removal requests are honored, depending on the site. If you are working with numerous site owners, either some of them will respond or you are likely doing something wrong. Ways to contact a webmaster:
-
use the WHOIS information to send an email
-
use information from the site. Before you say they don't have anywhere, check thoroughly.
-
use the site's Contact Us form
-
call the site with the number on the site or their WHOIS phone number
-
mail the site
-
check for social pages such as facebook and contact them via that method
You shared there are around 20 sites linking to your client's site. Some of them should respond.

That's good. Sorry, but I had missed the part where you said your clients site was compromised previously....
-
Thanks Gordon,
The links are no-follow so for the time being I'm not too worried about link spam penalties. We'll try to contact the site owners first and will then disavow the links if nothing else works...
Cheers, Matt

Thanks for your detailed reply Ralph As for the client's site hacking, as far as I'm aware their webmaster & in-house team dealt with that when it happened. I will pass your notes on to the team and check they are 100% confident that the security lapses are fixed. We are in the process of identifying & contacting the webmasters of the referring sites to requests the links be remove. However, if our messages go unacknowledged, what else can we do about it? The links are mostly no-follow which is a minor blessing and we haven't seen any link manipulation warnings in GWT yet. Still confused on their motives/reasons though.

"The client's site was compromised a few months ago and had a bunch of spam links inserted into the homepage code."
Has the issue been fully resolved? What steps have you taken to ensure the site's code is clean and remains clean? Some examples:
- placing the code on a test server and having an expert examine the code
- crawling the site and examining all links
- upon completion of the code analysis, implement a system which detects any coding changes and notifies you of the change
- ensure you are using professional development services with professionally developed extensions
- check your hosting. At a minimum, VPS hosting should be used. Do you have a firewall in place? What type of precautions does the host take (i.e. are you with a major host such as Rackspace, HostDime, etc? Or a host no one has heard of?)
- Use a service such as Symantec or McAfee SSL which offers daily site malware scanning
Every time I have worked with a compromised site, there have been major gaps or a complete lack of site security.
With respect to the links, the Disavow Tool can be used as a means of last resort. Google is very clear the tool should not be used until all other methods have been exhausted.
Have you tried contacting any of the webmasters to inquire about the links? That would be a start. You stated they are from independently owned sites. If that is true, then some of those webmasters will likely be cooperative and help you understand why they are linking to you.
We are happy to help Matthew. There is a lot more detailed information required which is missing from your question. There are dozens of possible causes and solutions.

Hi Matthew,
Sorry to hear this, and it's not good news. As to how/why it's happened, I can only guess one of two resaons. Either someone who knows nothing about SEO has decided s/he would "help" the whole SEO process and buy some links in. Or, and possibly more likely it may be a competitor who is doing a negative SEO campaign with the desire to lower your organic rankings, ensuring you will be penalised by Google.
You can now use the Google Webmaster tools and use the disavow tool to tell Google to ignore those links.
Hope that helps and all the best.
Gordon

Moving content form Non-performing site to performing site - wihtout 301 Redirection
I have 2 different websites: one have good amount of traffic and another have No Traffic at all. I have a website that has lots of valuable content But no traffic. And I want to move the content of non-performing site to performing site. (Don't want to redirect) My only concern is duplicate content. I was thinking of setting the pages to "noindex" on the original website and wait until they don't appear in Google's index. Then I'd move them over to the performing domain to be indexed again. So, I was wondering If it will create any copied content issue or not? What should i have to take care of when I am going to move content from one site to another?

Multiple Versions of Mobile Site
Hey Guys, We have recently finished the latest version of our mobile site which means currently we have 2 mobile sites. Depending on what device and Os will depend on which site you will be presented with.
White Hat / Black Hat SEO | | seekjobs
e.g.
iPhone 3 or 4 users on iOS4 will get version 1 of our mobile site
iPhone 5 users on iOS5 will get the new version (version 2) of our mobile site. Our old mobile site is currently indexed in Google and performing pretty well.
Since the launch of the second mobile site we have not see any major changes to our visibility in Google and so was curious My main concern here is duplicate content so I am curious can Google detect that we have 2 mobile site that we serve depending on device? And if Google can detect this, why has our sites not been penalized! Thanks, LW I know the first thing that comes to your mind is Duplicate content0 -
Are these links bad for my results?
In the past we have requested links on multiple directories. Since we have seen a mayor drop (60% in traffic) in results around the pinquin update 24-26th of April. Our results have been slowly getting lower and lower in Google. Is it possible to tell if these links are in fact doing my site harm? Before the 26th of April it was easy to see that the results where benefiting from the submission to those directories. We did not have any messages in webmaster tools and reconsideration says "no manual spam action taken". What would be the best strategy to turn this around and go up again? A selection of the requested links can be found below. <colgroup><col width="266"></colgroup>
