Black Hat vs. White Hat vs. Grey Hat SEO: The Definitive Guide

Let’s face it: as long as there is a logical-sounding, convenient (useful) label floating around, it will get used and mis-used. That is the story of “Black Hat SEO” and “White Hat SEO”. They are poor quality labels, poorly-defined (in practice), yet so easily “understood” and so convenient that they persist… year after year.

Personally I believe that these labels are good for Google, and bad for SEO practitioners. I believe that by labeling SEO as “black” or “white”, Google gains an opportunity to influence the popular perception of SEO in it’s favor, where otherwise it would not have such an opportunity. Of course Google has used this to its advantage many times (such as the times it has cautioned web site owners not to trust SEOs, because they may employ Black Hat tactics…F.U.D.). As I have said before, there is only one color of SEO worthy of effort, and that’s Green SEO.
So while it is unfortunate that we have to accept these labels, we do have to accept them because our clients think they understand them. Therefore, it is also essential that we properly define them.

That’s really quite easy to do, especially when you start with the definition of “Black Hat” SEO:

Black Hat : techniques or tactics which have been defined by Google as in violation of the Google “Quality Guidelines” (see “Quality Guidelines, which outline some of the illicit practices that may lead to a site being removed entirely from the Google index”) . The Black Hat label applies to those methods specifically mentioned n the “Guidelines”, other methods and/or tactics or circumstances mentioned by Matt Cutts in his blog, in Matt’s comments on others’ blogs, or just about anywhere anyone from Google says anything that strongly suggests Google took action against a site for some specific reason. Black Hat SEOs know what they are doing is defined as BAD, and do it anyway for specific reasons (not usually including “get banned”). I like to think of Black Hat SEOs as opportunists. They see an opportunity to gain, and take it, managing the associated risk. Please don’t confuse ignorant SEOs with Black Hat SEOs… the ignorant ones are those who execute on Black Hat (evil) tactics without managing the risks (either out of ignorance or folly doesn’t matter to me here).

White Hat: techniques or tactics which can be defended as NOT being contrary to the spirit of Google’s expressed quality desires, by citing Google’s own published guidelines, Matt Cutts’ blog posts, or comments posted in other places, or just about any other Google communication. I like to refer to White Hat SEOs as “conservatives” of the SEO world… where things are viewed as BLACK or WHITE (GOOD or BAD), and the letter of the Google god is taken verbatim as TRUTH. Yes, there is a bit of a timeline problem with that approach (if Matt said it was bad in 2002, is it still bad?) but that’s just the tip of the White Hat iceburg.

Grey Hat (or Gray Hat): Since the color gray is between black and white, logically Grey Hat SEO sounds like a label for the middle ground. But it’s not. Because White is pure white and grey is a shade of black, we have confusion. Some say Grey Hat is NOT White Hat and is just a shade of Black Hat. So let’s step away from the coor wheel and define Grey Hat as the practice of tactics/techniques which remain ill-defined by all that published material coming out of Google, and for which reasonable people (not White Hat SEOs, mind you, but “reasonable people”) could disagree on how the tactics support or contrast with the “spirit” of Google’s published guidelines.

Updated 06/2007: In response to comments, and recent emphasis by Google on webmaster intent,  I would say Gray Hat includes all areas where you feel you need to have some plausible deniability in place for your actions. Personaly I don’t believe in gray hats… but for the Definitive Guide, let it be defined.
So here we have the Definitive Definition of Black Hat vs. White Hat vs. Grey Hat. In summary, Black Hats know they are taking risks, defying some of Google’s expressed behavior guidelines. White Hats will only do what Google says is ok, and Grey Hats will try things which they believe are ill-defined by Google, without first asking permission.

According to Google, White Hat SEO is good, Black Hat SEO is bad, and most Grey Hat SEO is risky (ill-advised — see note below).

To the Black Hat SEO, White Hat SEO is non-competitive, Grey Hat SEO is a safe bet, and Black Hat SEO is the only thing that will beat good Grey Hat SEO.

To the Grey Hat SEO, White Hat SEO is effective only for SERPs where there are no Grey Hat or Black Hat SEOs, Black Hat SEO is for high-risk, high-yield opportunities, and in most cases, the term “SEO” means either Black Hat SEO or Gray Hat SEO. The rest is just good web mastering.

To the White Hat SEO, Black Hat SEOs are cheaters who need to be reported to Google, Gray Hat SEOs are quitters who need to be reported to Google (just in case it might get them penalized and dropped from the SERPs), and White Hat SEOs are good people worthy of reciprocal link exchanges (especially third-party exchanges), raving blind testimonials, and unconditional support.

I hope that helps clear up some of the confusion, and we can all move on from here. I suppose a good first step would be to gather every word ever uttered by Google on SEO, and update each item for the today tomorrow today (every day?), so we can know exactly what is Black or White. Then we can write down every other possible approach to web design, including those not yet invented, and make a big comprehensive list. We can then set up a meeting with Matt Cutts to label them as either Black or White. Whenever he has to “ask the right people at Google and get back to us”, we will label the item as Grey. That way we, as an industry, can use these new definitive definitions of Black/White/Grey to our advantage and clear up the confusion once and for all. If we are successful, we can publish an book, listing the Black Hat, White Hat, and Grey Hat SEO tactics everyone can use. Or better yet, just list the White Ones (since by definition, non-White tactics will be ill-defined or ill-advised).

We can call is the SESO Book, for Search Engine Sub-Optimization Book. Possibly we can do away with SEO altogether, in favor of SESO. We might even be able to get Google to pony up some of that AdWords/AdSense profit to support an Association. Maybe an Association for Sub-optimal Search Engine Services?

I may be projecting a bit far ahead here, but even with such an excellent industry catalog of tactics and techniques, I suppose there will still be an item or two that eludes a static assignment of risk as pertains to Google’s SERP-busting sledgehammer of Justice. Perhaps something that changes, or an item which isn’t easily labeled outside of its context. It could happen. So for those who really need to work with those edge circumstances, we can simply lump them together into a category called competitive webmastering.

Note: Google includes a threat statement in it’s Webmaster Guidelines that alludes to Grey Hat SEO as ill-advised, and indirectly calls it “spam” : “It’s not safe to assume that just because a specific deceptive technique isn’t included on this page, Google approves of it. Webmasters who spend their energies upholding the spirit of the basic principles will provide a much better user experience and subsequently enjoy better ranking than those who spend their time looking for loopholes they can exploit…If you believe that another site is abusing Google’s quality guidelines, please report that site… spam reports we receive are used to create scalable algorithms that recognize and block future spam attempts.” — emphasis added.

    John, you’re always trying to make people think. Too bad most won’t!

    IMO, and I think perhaps in your opinion as well, anyone who has to actually read what Google says about SEO in order to know what to do, is just a guinea pig SEO and needs to get out of the biz, ASAP.

  3. Daniel Says:

    In the end, it is not good business to guide people towards the Grey or Black area of SEO. Somehow, the blame will come back, and haunt you, from one angry customer, whose site got banned by Almighty Google using the techniques from the Dark Side.

    Not worth the headaches, nor the angry customer, who will troll every forum to give you a bad rap.

    People forget this is the World According to Google.Just play within the boundaries – there is so much to learn and to do – why waste your time otherwise?

    If you disagree, bring a warm jacket – I hear Siberia is a cold place.

    Sorry, but there is no such thing as black hat, because what the black hats really do to get ranked is not mentioned Google’s Guidelines. The most notorious trick next to spamming applications is linkbait, which is has been classified as a white hat tactic. Personally, I am not one for risk, I don’ even gamble, so the shady stuff is not something I would touch. I remember back when people included iframes on gov’t sites to get some rank passed, along with having google index their own results giving rank to the sites who were linked from the google results. It made me laugh, but I never took part.

  7. Ken Says:

    @Matt Sandy,

    Such a bold statement you’ve made. The statement above dictates that ”
    “it’s not safe to assume that just because a specific deceptive technique isn’t included on this page, Google approves of it.” To argue, black-hat seo does exist and includes things as simple as hidden text, and keyword stuffing.

    As for the article, the content here is very useful, the explanation on grey-hat seo is a bit muddy and could use a revision, but the point does eventually come across correctly.

    Hi.. Thanks for the info. I’m new at this and I’ve heard these phrases before, but never understood them. I am curious though. What exactly is “linkbait”?? I haven’t heard of that one yet.

  14. Vikas Says:

    Well Thanks for the information. At the same time if you could add features of theses SEO techniques would be great for me as well as all new SEO aspirants.

    Best Regards

  15. Ki David Says:

    Very nice explanation of white hat – grey hat and black hat. I personally like black hat the most, white hat won’t get you far. Just my opinion!

  16. The Dog Walker Says:

    If we look at the overall views of Mr Cutts the Google position is quite simple:

    Google wants to return a relevant result any given search, this position has not
    changed over time.

    Most self publishing website owners are not even aware of the term SEO never mind the shade
    of grey that any given SEO conforms to.

    The real Black Hats are very easy to spot as they mostly are or work for black hat sites,
    loans, cash, gold, make a million etc.

    For a local business there is no substitute for simple hard work, work on your target market and geographic area and attract people looking the exact services that you are offering.

    In my case none of the Hats are interested in “Dog walking Buckhurst Hill” and I am doing OK thank you.

  17. Heather Says:

    Just doing research for a mini paper on white-hat vs black-hat vs grey-hat and thought your page was hilarious. Couldn’t stop laughing at some of the pokes at Google. I personally believe that we need to invent some site that screws Google sideways as it is now a giant and if it continues to grow, no one and nothing will be able to compare. It is telling us what to do in web design and promotion, next thing we know it will be telling us how when, and how hard to wipe our a**!

    Good job on the site!

  18. Fantomaster Says:

    Most link building by most SEO firms is not “natural” and is in fact blackhat according to Google. If you have to pay for it, ask for it, comment for it or insert a link in your article to gain it, then you are manipulating Google search results and Google terms that as blackhat. You just need to view the many video’s by Matt Cutts to realize that if you are doing any of the above, then you are creating links manually and you violating Google’s TOS.

    It simply baffles me how many SEO experts will quickly denounce Cloaking as “unethical” or against Google’s TOS or even label it as spam which manipulates search results but then on a daily basis create artificial, manual or software generated backlinks for clients.

    If you are distributing countless articles with links or posting on blogs/forums to obtain backlinks or using automated backlinking software, isn’t that also spamming to manipulate search engine results?

    What is the difference? It all violates Google’s TOS.

    So does “blackhat” or being “unethical” really exist anymore? Isn’t this really about traffic, conversions and surviving within an ever tightening monopoly created by Google for which we now are left with few other options, unless to line the pockets of Google shareholders.
