Black hat SEO refers to a set of practices that are used to increases a site or page’s rank in search engines through means that violate the search engines’ terms of service.
We should know basic terms which should be avoided while doing SEO as they considered to be Black Hat
What is a PBN (Private Blog Network)?
A PBN is a collection of high authority websites that you have complete control over and all of which link back to your money site.
Typically PBNs are made of expired domains that have great backlinks and therefore pass high levels of link equity to your money site
PBNs are a shortcut method to get high-quality backlinks in large quantities without having to perform the tedious tasks typically done for link building.
There is a trade-off when using PBNs. As an SEO you accept the higher risk of a penalty for a better chance at controlling the links (quality + content + anchor text).
You should also note that most SEOs use PBNs along with other white hat link building strategies. They never use PBNs on sites that have no links and always try and have a mix of backlinks i.e. natural organic backlinks from outreach as well as PBN links. PBN links let them tweak the anchor text to ensure that the sites rank for specific keywords.
Building a PBN takes a lot of money and a lot of effort. You, therefore, want to treat this as a prized asset and want to build it to last for many more years to come. Below are reasons why PBNs get deindexed as well as rules that you should follow to ensure that you keep your PBNs as safe as possible.
By definition, keyword stuffing involves overusing the same keywords throughout one page in order to maximize its visibility and organic traffic. Content stuffed with keywords doesn’t look natural and because of this, it’s not user-friendly.
If you were to do keyword stuffing use a site like writeraccess.com to get a bunch of content written for you for cheap and then load your main keywords into a tool like LSI graph and get all of the variations of keywords and stuff them into your different h tags, bold and italics, and internal / external links. After, use a site like seoprofiler.com to check for over optimization via keyword density to content ratio.
Matt Cutts explains it clearly:
The vast majority of the time things are incredibly clear: people are paying money outright for links based on PageRank, flowing the PageRank, trying to get high the rankings.
He also adds that:
Ninety-nine percent of the time it’s abundantly clear that these are links that are being bought and paid and sold and all that sort of stuff.
Buying links for SEO has some undeniable advantages for the buyer. First of all, it is easy. Once a transaction is done, there is no need to bother with the quality of the content. Secondly, the anchor text, a strong Google ranking factor, is also chosen according to customer’s preferences. These two reasons are enough to effectively manipulate search engine rankings which is why this SEO technique is classified as a serious black hat.
Although this isn’t completely black hat, social media can be heavily abused. Social signals are obviously a ranking factor these days and there
are some seriously crazy methods you can use to hack your social signals.
