Black hat SEO
Manipulative techniques that try to trick search engines, such as bought links, hidden text, keyword stuffing or generated content with no value. They may help briefly but risk penalties and lost rankings.

What it means
Black hat SEO covers techniques that try to win higher search rankings by tricking the algorithm rather than improving the page for people. They include buying links, networks of artificial sites, hidden text, keyword stuffing and mass-produced content with no value.
The opposite is white hat SEO, which follows search engine guidelines and relies on quality content, technical quality and natural links. Between them lies a grey zone, such as aggressive link exchanges.
Search engines actively detect black hat techniques through algorithms and manual review. The result can be a ranking drop, a manual penalty or removal of the site from the index altogether.
How it works in practice
Companies usually encounter black hat SEO through offers of cheap link packages or agencies promising the top spot within weeks. Such promises signal that the supplier uses risky practices.
If a site receives a manual penalty, a notice appears in Search Console. Recovery means removing or disavowing harmful links, cleaning up content and requesting reconsideration, which can take months.
When choosing an SEO supplier, ask for a transparent list of activities and links. The contract should prohibit techniques that breach search engine guidelines and set liability for damage.
What to watch out for
A short-term traffic boost from black hat techniques can turn into long-term loss when an algorithm update arrives. Rebuilding a search engine's trust usually costs more than doing honest SEO from the start.
Beware also of negative SEO, where competitors deliberately point thousands of spam links at a site. Regularly checking the link profile helps spot such an attack early.
