        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.

            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.

                  Is domain redirection a good method for SEO?

                  I have a question and need suggestion from you guys. I’ve searched for my question on Google but don’t get exact information what I need. Maybe I can’t search perfectly.
                  Let me explain my confusion:
                  I’ve checked backlink profile of a website. He is not using his main domain while doing comment backlink. He put his another domain while doing comment backlink. The another domain redirect to the main domain. Why he use another domain while doing comment backlink?
                  Is it helpful to get better rank on Google? For example: My Main Domain = solutionfall.com
                  Another Domain= xyz.com (It redirect to solutionfall.com)
                  He just uses xyz.com while doing comment backlink. Thank You so much

                  Do I lose link juice if I have a https site and someone links to me using http instead?

                  We have recently launched a https site which is getting some organic links some of which are using https and some are using http. Am I losing link juice on the ones linked using http even though I am redirecting or does Google view them the same way? As most people still use http naturally will it look strange to google if I contact anyone who has given us a link and ask them to change to https?

                  Why does expired domains still work for SEO?

                  Hi everyone I’ve been doing an experiment during more than 1 year to try to see if its possible to buy expired domains. I know its considered black hat, but like I said, I wanted to experiment, that is what SEO is about. What I did was to buy domains that just expired, immediately added content on a WP setup, filled it with relevant content to the expired domain and then started building links to other relevant sites from these domains.( Here is a pretty good post on how to do, and I did it in a similar way. http://searchenginewatch.com/article/2297718/How-to-Build-Links-Using-Expired-Domains ) This is nothing new and SEO:s has been doing it for along time. There is a lot of rumors around the SEO world that the domains becomes worthless after they expire. But after trying it out during more than 1 year and with about 50 different expired domains I can conclude that it DOES work, 100% of the time. Some of the domains are of course better than others, but I cannot see any signs of the expired domains or the sites i link to has been punished by Google. The sites im liking to ranks great ONLY with those links 🙂 So to the question: WHY does Google allow this? They should be able to see that a domain has been expired right? And if its expired, why dont they just “delete” all the links to that domain after the expiry date? Google is well aware of this problem so what is stopping them? Is there any one here that know how this works technically?

                  Site dropped suddenly. Is it due to htaccess?

                  I had a new site that was ranking on the first page for 5 keywords. My site was hacked recently and I went through a lot of trouble to restore it. Last night, I discovered that my site was nowhere to be found but when i searched site: mysite.com, it was still ranking which means it was not penalized. I discovered the issue to be a .htaccess and it have been resolved. My question is now that the .htaccess issue is resolved , will my site be restored back to the first page? Is there additional things that i should do? I have notified google by submitting my site

                  Closing down site and redirecting its traffic to another

                  OK - so we currently own two websites that are in the same industry. Site A is our main site which hosts real estate listings and rentals in Canada and the US. Site B hosts rentals in Canada only. We are shutting down site B to concentrate solely on Site A, and will be looking to redirect all traffic from Site B to Site A, ie. user lands on Toronto Rentals page on Site B, we're looking to forward them off to Toronto Rentals page on Site A, and so on.  Site A has all the same locations and property types as Site B. On to the question: We are trying to figure out the best method of doing this that will appease both users and the Google machine.  Here's what we've come up with (2 options): When user hits Site B via Google/bookmark/whatever, do we: 1. Automatically/instantly (301) redirect them to the applicable page on Site A? 2. Present them with a splash page of sorts ("This page has been moved to Site A.  Please click the following link <insert anchor="" text="" rich="" url="" here="">to visit the new page.").</insert> We're worried that option #1 might confuse some users and are not sure how crawlers might react to thousands of instant redirects like that. Option #2 would be most beneficial to the end-user (we're thinking) as they're being notified, on page, of what's going on.  Crawlers would still be able to follow the URL that is presented within the splash write-up. Thoughts?  We've never done this before.  It's basically like one site acquiring another site; however, in this case, we already owned both sites.  We just don't have time to take care of Site B any longer due to the massive growth of Site A. Thanks for any/all help. Marc

                  Does posting on Craigslist damage our SEO or reuptation?

                  We have a website that's a single person barbershop. She has been promoting on Craigslist, and that is outranking the website in the SERPs. However, the craigslist results showing up are actually expired and don't link to anything. They just seem to be cached by Craigslist. My question is, is Craigslist considered to generally not be a good avenue for directing inbound links for services on your site? Or is it a good strategy to use Craigslist to build link traffic for service businesses? I get mixed responses when I search for this. Thanks eYtdHtg.png
