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.

Does ID's in URL is good for SEO? Will SEO Submissions sites allow such urls submissions?
Example url: http://public.beta.travelyaari.com/vrl-travels-13555-online It's our sites beta URL, We are going to implement it for our site. After implementation, it will be live on travelyaari.com like this - "https://www.travelyaari.com/vrl-travels-13555-online". We have added the keywords etc in the URL "VRL Travels". But the problems is, there are multiple VRL travels available, so we made it unique with a unique id in URL - "13555". So that we can exactly get to know which VRL Travels and it is also a solution for url duplication. Also from users / SEO point of view, the url has readable texts/keywords - "vrl travels online". Can some Moz experts suggest me whether it will affect SEO performance in any manner? SEO Submissions sites will accept this URL? Meanwhile, I had tried submitting this URL to Reddit etc. It got accepted.

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,

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!

Tags on WordPress Sites, Good or bad?
My main concern is about the entire tags strategy. The whole concept has really been first seen by myself on WordPress which seems to be bringing positive results to these sites and now there are even plugins that auto generate tags. Can someone detail more about the pros and cons of tags? I was under the impression that google does not want 1000's of pages auto generated just because of a simple tag keyword, and then show relevant content to that specific tag. Usually these are just like search results pages... how are tag pages beneficial? Is there something going on behind the scenes with wordpress tags that actually bring benefits to these wp blogs? Setting a custom coded tag feature on a custom site just seems to create numerous spammy pages. I understand these pages may be good from a user perspective, but what about from an SEO perspective and getting indexed and driving traffic... Indexed and driving traffic is my main concern here, so as a recap I'd like to understand the pros and cons about tags on wp vs custom coded sites, and the correct way to set these up for SEO purposes.

Would having a + plus sign between keywords in meta title have an effect on SEO?
I have seen one of my clients' competitors do this in their meta title and it got me a little intrigued... I understand that google uses the + sign as an operator in adwords, and to a certain extent, as a search tool, but would it help or make any difference to the SEO in the meta title/data (eg. 'SEO+Marketing+Services')? Thanks

Merging four sites into one... Best way to combine content?
First of all, thank you in advance for taking the time to look at this. The law firm I work for once took a "more is better" approach and had multiple websites, with keyword rich domains. We are a family law firm, but we have a specific site for "Arizona Child Custody" as one example. We have four sites. All four of our sites rank well, although I don't know why. Only one site is in my control, the other three are managed by FindLaw. I have no idea why the FindLaw sites do well, other than being in the FindLaw directory. They have terrible spammy page titles, and using Copyscape, I realize that most of the content that FindLaw provides for it's attorneys are "spun articles." So I have a major task and I don't know how to begin. First of all, since all four sites rank well for all of the desired phrases-- will combining all of that power into one site rocket us to stardom? The sites all rank very well now, even though they are all technically terrible. Literally. I would hope that if I redirect the child custody site (as one example) to the child custody overview page on the final merged site, we would still maintain our current SERP for "arizona child custody lawyer." I have strongly encouraged my boss to merge our sites for many reasons. One of those being that it's playing havoc with our local places. On the other hand, if I take down the child custody site, redirect it, and we lose that ranking, I might be out of a job. Finally, that brings me down to my last question. As I mentioned, the child custody site is "done" very poorly. Should I actually keep the spun content and redirect each and every page to a duplicate on our "final" domain, or should I redirect each page to a better article? This is the part that I fear the most. I am considering subdomains. Like, redirecting the child custody site to childcustody.ourdomain.com-- I know, for a fact, that will work flawlessly. I've done that many times for other clients that have multiple domains. However, we have seven areas of practice and we don't have 7 nice sites. So child custody would be the only legal practice area that has it's own subdomain. Also, I wouldn't really be doing anything then, would I? We all know 301 redirects work. What I want is to harness all of this individual power to one mega-site. Between the four sites, I have 800 pages of content. I need to formulate a plan of action now, and then begin acting on it. I don't want to make the decision alone. Anybody care to chime in? Thank you in advance for your help. I really appreciate the time it took you to read this.
