How to check if a site is doing blackhat SEO?
-
Thanks in advance!
-
It really depends on what you define as blackhat. On-page trickery (cloaking, redirects for search engines bots, etc.) can be discovered by browsing as a search bot, digging into code, viewing caches, etc. Danny Sullivan and Rand uncovered a large amount of cloaked (and stolen) content on stage at SMX Sydney a few years ago. It was quite entertaining at the time
Some people are basic enough to use tactics like hidden, white-on-white text, as Martijn says. I'm yet to see that tactic actually working post-2004 though
If it's links they're using, the easiest way is to use a tool like Open Site Explorer, Ahrefs or similar to check the links out. Sneaky people can block the OSE / Ahrefs / MajesticSEO bots from crawling the sources of their backhat links if they have access to the linking sites. You can block the bots either in robots.txt or by rejecting the visits to stop the bots from noting that the links exist. That way, the backlink analysis tools will never see that blackhatsite.com links to rankingsite.com, and so forth. It takes a big network that the spammer controls to block link research tools' bots' access to every link you build, however, so this isn't too common.
Whether all big brands / well ranked sites are using blackhat tactics pretty much depends on your definition of blackhat, but it's certainly true that it is very hard if not impossible to rank top 3 for competitive terms (car insurance, poker, credit cards) without parting with money that results in links being built. This doesn't mean that they're all buying links, but they're definitely investing in marketing that results in links, and the whitest of the whitehats will say that this is technically not organic, natural link development. It is, however, what we do - marketing.
-
Why does it matter?
-
An even easier way is to check their rankings - if they're top 3 for big money terms in their niche, they're probably using some blackhat tactics. Even the whitest of whitehats are still using some blackhat tactics in the background, despite people not wanting to admit it.
-
I can't agree more with Gary, we probably need some more information to know what kind of black hat you're possibily dealing with. One of the first things I tend to look at trying to find out if the site is using some ways of black hat tactics are:
- Backlink profile, if the quality of links is low or certain percentages between follow/ nofollow links are different then it could be a sign.
- Look at the site with Google as a user agent and see if the site is showing different information then to a real user.
- Just do a select all on the site to see if they hide any content (yup, still happens).
-
Your question is a bit to open ended, what do you want to achieve by knowing this information.
Does a site rank better than you?
Are they doing negative seo to other people?
Do they steal content from people?Are they building links as dofollow from places they should not?Too many questions to ask before answering such a vague answer.

Opinion on Gotch SEO methods & services
I would love to get you all's take on Gotch SEO. I am gearing up to link build for a site in the next several months, and have been reading up from sources other than Moz, in preparation. (Need to re-read Moz's guide, too, but I have already read it last year) I'm reading Gotch SEO's main link building method articles right now, and am wondering what you all think. Do you think they have a good approach and are generally reliable? Likewise, has anyone used their service for getting a link? What was your experience? Or if you haven't used the service, any quick takes on it?

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!

A site is using their competitors names in their Meta Keywords and Descriptions
I can't imagine this is a White Hat SEO technique, but they don't seem to be punished for it by Google - yet. How does Google treat the use of your competitors names in your meta keywords/descriptions? Is it a good idea?

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. MB.

Recovering From Black Hat SEO Tactics
A client recently engaged my service to deliver foundational white hat SEO. Upon site audit, I discovered a tremendous amount of black hat SEO tactics employed by their former SEO company. I'm concerned that the efforts of the old company, including forum spamming, irrelevant backlink development, exploiting code vulnerabilities on BB's and other messy practices, could negatively influence the target site's campaigns for years to come. The site owner handed over hundreds of pages of paperwork from the old company detailing their black hat SEO efforts. The sheer amount of data is insurmountable. I took just one week of reports and tracked back the links to find that 10% of the accounts were banned, 20% tagged as abusive, some of the sites were shut down completely, WOT reports of abusive practices and mentions on BB control programs of blacklisting for the site. My question is simple. How does one mitigate the negative effects of old black hat SEO efforts and move forward with white hat solutions when faced with hundreds of hours of black gunk to clean up. Is there a clean way to eliminate the old efforts without contacting every site administrator and requesting removal of content/profiles? This seems daunting, but my client is a wonderful person who got in over her head, paying for a service that she did not understand. I'd really like to help her succeed. Craig Cook

Would linking out to a gambling/casino site, harm my site and the other sites it links out to?
I have been emailed asking if I sell links on one of my sites. The person wants to link out to slotsofvegas[dot]com or similar. Should I be concerned about linking out to this and does it reduce the link value to any of the other sites that the site links out to? Thanks, Mark
