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.

Is this campaign of spammy links to non-existent pages damaging my site?
My site is built in Wordpress. Somebody has built spammy pharma links to hundreds of non-existent pages. I don't know whether this was inspired by malice or an attempt to inject spammy content. Many of the non-existent pages have the suffix .pptx. These now all return 403s. Example: https://www.101holidays.co.uk/tazalis-10mg.pptx A smaller number of spammy links point to regular non-existent URLs (not ending in .pptx). These are given 302s by Wordpress to my homepage. I've disavowed all domains linking to these URLs. I have not had a manual action or seen a dramatic fall in Google rankings or traffic. The campaign of spammy links appears to be historical and not ongoing. Questions: 1. Do you think these links could be damaging search performance? If so, what can be done? Disavowing each linking domain would be a huge task. 2. Is 403 the best response? Would 404 be better? 3. Any other thoughts or suggestions? Thank you for taking the time to read and consider this question. Mark

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?

Preventing CNAME Site Duplications
Hello fellow mozzers! Let me see if I can explain this properly. First, our server admin is out of contact at the moment,
White Hat / Black Hat SEO | | David-Kley
so we are having to take this project on somewhat blind. (forgive the ignorance of terms). We have a client that needs a cname record setup, as they need a sales.DOMAIN.com to go to a different
provider of data. They have a "store" platform that is hosted elsewhere and they require a cname to be
sent to a custom subdomain they set up on their end. My question is, how do we prevent the cname from being indexed along with the main domain? If we
process a redirect for the subdomain, then the site will not be able to go out and grab the other providers
info and display it. Currently, if you type in the sales.DOMAIN.com it shows the main site's homepage.
That cannot be allow to take place as we all know, having more than one domain with
exact same content = very bad for seo. I'd rather not rely on Google to figure it out. Should we just have the cname host (where its pointing at) add a robots rule and have it set to not index
the cname? The store does not need to be indexed, as the items are changed almost daily. Lastly, is an A record required for this type of situation in any way? Forgive my ignorance of subdomains, cname records and related terms. Our server admin being
unavailable is not helping this project move along any. Any advice on the best way to handle
this would be very helpful!0 -

Rollover design & SEO
After reading this article http://www.seomoz.org/blog/designing-for-seo some questions came up from my developers. In the article it says "One potential solution to this problem is a mouse-over. Initially when viewed, the panel will look as it does on the left hand side (exactly as the designer want it), yet when a user rolls over the image the panel changes into what you see on the right hand side (exactly what the SEO wants)." My developers say" Having text in the rollovers is almost like hiding text and everyone knows in SEO that you should never hide text. "In the article he explains that it is not hidden text since its visible & readable by the engines.What are everyone's thoughts on this? Completely acceptable or iffy?Thanks
