The Black Hat SEO
Black Hat SEO (black hat) is a natural SEO technique that does not comply with the recommendations of search engines and can be penalized by the latter. Some practices may even be illegal and therefore punishable by law. The objective for the SEO practitioner is to be positioned on the first SERPs (the results pages of a search engine) of strategic keywords.
This is a short-term strategy, a site that does not comply with the instructions of search engines can not position itself in a stable and sustainable manner on the requests that interest him. Let’s take stock of some black hat SEO techniques regularly used to boost the visits of a website.
Cloaking is a “black hat” practice that consists of configuring a web server so that it does not present the same page of HTML content to Internet users and search engine spiders. For example, keywords can be inserted in a page only if the user agent signature corresponds to a search engine. If this technique is found, the search engine will penalize the site, which may see its positioning deteriorate rapidly. BMW had made the bitter experience in 2006, its site had been deindexed from Google several days.
AUTOMATIC BACKLINK GENERATION
The use of automated programs or software to create numerous inbound links to a site is strongly discouraged by Google. The goal is to massively increase the number of backlinks pointing to a site, however they can have a negative impact on its ranking in search results pages.
Rather than optimizing one’s own SEO and gaining visibility, malevolent people may try to penalize a competitor’s natural SEO. The most common methods of negative SEO are :
– duplication of content and source code of web pages;
– mass spamming of a site with poor quality inbound links.
Google defines “satellites” as: “pages or sites created for optimal ranking in search results in response to specific queries. For example, multiple pages or domain names may target specific geographic areas. By clicking on these links in search engines, users will be redirected to the same page.
Sometimes sites are hacked for malicious SEO purposes. Indeed, hackers may try to insert links and redirections from a site they have hacked to a site they want to better reference. More than not respecting the general instructions of search engines, this is above all an illegal act that can be condemned by law.

Spam Filtering, Indexing and Analysis: Filtrar-S and Signal Spam work presented at
On the occasion of WISG 2012 (Interdisciplinary Workshop on Global Security), the research project Filtrar-S and Signal Spam publish an article presenting the results of a test of the software designed and developed within the framework of the ANR-funded Filtrar-S project on a sample of unwanted, anonymized messages provided by Signal Spam.
Filtrar-S uses a semantic filtering module capable of uncovering non-predefined “topics” on a diverse corpus of texts. The application responds to a need of the Gendarmerie Nationale’s Division de Lutte Contre la Cybercriminalité, and Signal Spam provided a spam sample for the occasion: the test demonstrated that the semantic filtering module is capable of identifying scam messages that take the form of an e-mail and/or the name of a trusted sender in order to trap the recipient or steal his bank details.
