But what we're talking about here is a clear attempt to completely hide the text, and this doesn't apply to text in an accordion, in tabs, or that's dynamically loaded using JavaScript. As far as we're concerned, we absolutely do not recommend adding hidden text to your pages. Search engine crawlers are much more sophisticated these days and understand that you're trying to force the use of keywords.
Satellite Pages
Creating pages that target specific search queries with content intended solely to funnel traffic to a page violates Google's guidelines. These pages are called doorway pages.
Each piece of content on your site should have a specific purpose, and you should not create pages simply to rank for keywords that are not entirely relevant.
Here are some examples:
Create pages that target geographically specific keywords in locations where your business doesn't have a physical presence, in order to direct users to a single page.
Pages created solely for the purpose of ranking in search queries rather than meeting a user's needs
Create content for humans, not for search engines.
- Cloaking
Cloaking (or dissimulation) is a tactic that involves serving different content or URLs to users and search engines, essentially providing a different experience on each.
This is a clear attempt to rank a page based on content created for search engines while redirecting users to another location (or something else entirely). This is a brother cell phone list deceptive practice, which makes it a violation of search engine guidelines.
Focus your efforts on designing the best possible experience for your users, and there's a good chance that search engines will appreciate your page for what it's worth.
Paid/Manipulative Links
Link schemes are one of the most common types of black hat SEO, and it's one of the practices that most often causes confusion.
It makes sense to many marketers to think that you should write content that works for your users and that you shouldn't hide any text. But when it comes to link building , things are a bit more complex.
The key is that your links are well-earned, especially considering they represent votes of trust from one website's editorial team to another. This means you should avoid the following tactics:

Excessive link exchanges
Unwanted comments on blogs
Unwanted comments in forums
Large-scale article or guest posting marketing campaigns
Automated link building
Directories, bookmarking sites, and unwanted Web 2.0 properties
Footer or sidebar links throughout the site
Links that use exact match or commercial anchor text
While structured data can help define entities, actions, and relationships online, one of the common black hat tactics is to abuse or misuse this type of markup.
This typically involves using structured data to present factually incorrect information, for example, by attempting to create structured data that is more favorable to one's website. Many marketers write fake reviews that give 5-star ratings to boost their company's position in SERPs and achieve a higher click-through rate (CTR).
Like the other tactics on this list, this is pure deception and not a tactic to be considered.
Misleading redirects
Whether you're updating an old page to a new URL or preparing for a site migration, redirects are commonplace in SEO. There's nothing wrong with that. It's the preferred method to ensure your site is well-organized and easily accessible to both users and search engine crawlers.
However, as with cloaking, deceptive redirects are used via black hat SEO tactics to trick search engines into displaying different content than what the user sees. Often, a search engine will index the original page while users are redirected to a different destination URL. Google's Webmaster Guidelines specifically identify deceptive redirects as a black hat tactic that violates its guidelines.
Negative SEO
It would be wrong to assume that all black hat SEO tactics are aimed at the site a marketer is trying to rank.
Some unethical SEO strategies use negative SEO to try to lower their competitors' rankings. Think of this type of SEO as a way to violate Google's guidelines on someone else's site rather than your own.
In practice, this usually involves directing a large number of unnatural links to someone else's domain in the hope that they will be penalized for it.
