        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.

                  Hiding Elements on Mobile. Will this effect SEO.

                  Hey guys and gals, I am hiding elements with @media sizes on the mobile experience for this site. http://prepacademyschools.org/ My question is when hiding elements from mobile, will this have a negative effect on rankings for mobile and or desktop? Right now it is a hero banner and testimonial. My interest is because I feel responsive is now working against conversions when it comes to mobile because desktop typically has the same info several times where mobile it can be repetitive and only needed once. Thanks,

                  Moz was unable to crawl your site? Redirect Loop issue

                  Moz was unable to crawl your site on Jul 25, 2017. I am getting this message for my site: It says "unable to access your homepage due to a redirect loop. https://kuzyklaw.com/ Site is working fine and last crawled on 22nd July. I am not sure why this issue is coming. When I checked the website in Chrome extension it saysThe server has previously indicated this domain should always be accessed via HTTPS (HSTS Protocol). Chrome has cached this internally, and did not connect to any server for this redirect. Chrome reports this redirect as a "307 Internal Redirect" however this probably would have been a "301 Permanent redirect" originally. You can verify this by clearing your browser cache and visiting the original URL again. Not sure if this is actual issue, This is migrated on Https just 5 days ago so may be it will resolved automatically. Not sure, can anybody from Moz team help me with this?

                  Does type of hosting affect SEO rankings?

                  Hello, I was wondering if hosting on shared, versus VPS, versus dedicated ... matter at all in terms of the rankings of Web sites ... given that all other factors would be exactly equal. I know this is a big question with many variables, but mainly I am wondering if, for example, it is more the risk of resource usage which may take a site down if too much traffic and therefore make it un-crawlable if it happens at the moment that a bot is trying to index the site (factoring out the UX of a downed site). Any and all comments are greatly appreciated! Best regards,
                  Mark

                  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?

                  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
